Guides, reference tables and the paperwork a first order turns on, from SGSBOTTLE, the MAIDAO INDUSTRY brand forming 700 million bottles a year on 14 lines in Shandong and Xuzhou. Your quotation carries the finish drawing and the loading plan; everything else a buying team asks a glass factory for lives in one library.
Certificates and test reports →The decisions a first container turns on, in the order a buying team meets them, with the numbers each one needs.
You choose from 27 stock categories and 10,000+ SKUs, 3 ml to 8 L (0.1 to 270 oz), on moulds that are already running. A first order can be a single pallet.
Browse the catalogue →Standard flint runs from 50,000 pieces on a custom mould, extra-flint from 12,000. The grade you specify decides which site forms your bottle and where your minimum sits.
Flint vs extra-flint →Your cap decides the jar. The finish drawing comes with every quotation, so your closure supplier confirms the match on paper before you commit a container to it.
Match a cap to a finish →An acrylic prototype at $500 in about 10 days, a sample mould at $1,200 in 35 days, production tooling at $1,200–2,200. Some shapes let you skip the sample mould altogether.
Stock mould or custom mould →Stock samples are free, and decorated samples come off the sample mould for sign-off. Every bottle gets a finish inspection at all two sites; a polariscope strain report joins your batch on request.
What a third-party inspection checks →About 25,000 bottles of 750 ml (25 oz) fill a 40HC in standard shapes. The loading plan for your cartons comes with the quote, with the certificates your customs broker and retailer ask for.
Container loading maths →Every guide, reference table and checklist files under one of the six questions a glass order raises.
Pillar 01
How a bottle takes shape, what flint, extra-flint and amber glass actually are, and the vocabulary your quotation and finish drawing are written in.
Pillar 02
Finish designations, capacity and weight tolerances, and whether the glass bottle you shortlist runs on the filling line and capping head you already own.
Pillar 03
Frosting, spray coating, screen printing, hot stamping, electroplating and labelling on glass, and what each process asks of your artwork, your minimum and your budget.
Pillar 04
From drawing to production glass mould in three priced stages, $500 acrylic, $1,200 sample mould and $1,200–2,200 production tooling, and the minimums that follow.
Pillar 05
How each site inspects every glass bottle, what the six transit failure modes look like, and which certificate answers which customs or retailer request.
Pillar 06
How many glass bottles fill a 40HC, what bulk and palletised loading each cost you, and what moves the price between EXW and your warehouse door.
Long-form answers with the numbers attached, each one reviewed against the figures our two sites actually run to. Start from your own question: your format, your closure, your market or your freight. Every guide closes with what your enquiry should carry, so your first message to us is one we can quote against.
How a bottle takes shape, what flint, extra-flint and amber glass actually are, and the vocabulary your quotation and finish drawing are written in.
Ninety-one glass packaging terms, annealing to twist-off, each with what it costs you when it goes wrong, from SGSBOTTLE's 14 lines in Shandong and Xuzhou.
From sand and cullet to a palletised container: the eight steps a glass bottle takes at SGSBOTTLE's two sites in China, and what each one decides for your order.
Standard flint or extra-flint (super-flint) for your bottle: where the green tint shows, which fills need water-white glass, and the MOQ behind each grade.
Barrier, weight, shelf life, freight, recycling and shelf presence, compared for your fill. Where glass earns its cost, and where PET is the honest answer.
Cans win on weight, chill speed and breakage; glass wins on shelf presence, reseal and taste neutrality. Where each earns its place in your range.
Glass colour is a furnace decision with an optical job. What amber, green, flint and extra-flint block, and how far a sprayed colour protects.
Borosilicate takes more thermal shock and costs more to melt. Where the difference is real, where it is oversold, and what container glass actually uses.
Sand, soda ash, limestone, cullet and the minor additions. What each contributes to your bottle, and why the batch decides colour and grade before forming.
Cullet is crushed recycled glass fed back into the furnace. What it does to energy, quality and your recycled-content claim, and why colour separation limits it.
A container furnace melts one colour continuously for years. What a campaign is, how furnace scheduling reaches your quotation, and why 2 colours cost more than 1.
Molten glass is cut into gobs before forming, and gob weight becomes bottle weight. How the feeder works, and why your freight bill starts here.
The individual section machine forms nearly every glass container. How a section works, what sets line speed, and what it means when a quotation names 6S or 8S.
Compressed air settles the gob and blows the parison, then blows it again to shape. How the oldest forming process works and where it still beats the alternative.
A plunger spreads glass more evenly than air. How press-and-blow works, what NNPB added, and how much weight your bottle can lose without losing strength.
The parison decides where your glass ends up. How thickness is set before the blow mould, why thin spots cluster in the same 4 places, and what you can ask for.
A bottle mould is a set, not one block. What the blank, blow, neck ring and baffle each do, and why your seam lines land exactly where they land.
Tin oxide is applied seconds after forming, before the lehr. What hot-end coating does to your glass surface, why it comes first, and how the thickness is checked.
The second coating goes on after the lehr and makes bottles slide instead of scrape. What lubricity buys you, how it is tested, and where it interferes with labels.
Colour in glass comes from metal ions in the melt, not from a coating. What iron, chromium, cobalt and the sulphur-carbon amber system each block, and what that protects.
One fluid ounce means two different volumes. A conversion chart for every trade size, both ounce systems side by side, and the rounding conventions the trade uses.
Eight ounces is 236.6 ml in the US and 227.3 ml in imperial measure. Where the 8 oz jar sits in the trade, and the mistake that ships the wrong size.
The wine and spirits standard converts to an awkward number in both ounce systems. Why 750 ml became the global format, and what it means for your bottle and your pallet.
12 US fluid ounces is 354.88 ml, sold as 355 ml. Why this size dominates North American drinks, how it compares with 330 ml, and what it does to your container count.
Brimful, nominal and fill point are three volumes and only one reaches your carton. What each means, which one your filler needs, and where the confusion costs a run.
16 US fluid ounces is 473.18 ml, but an imperial pint is 568 ml. What that gap does to your specification, and where the 16 oz format sits in the trade.
A litre is 33.81 US fluid ounces and 35.20 imperial ones. Where the 1 L format is a legal standard, where it competes with 750 ml, and what it does to your pallet.
250 ml is 8.45 US fluid ounces, so it is not the 8 oz trade size. Where the 250 ml format is a standard in its own right, and what the difference does to your fill.
Headspace is not wasted volume, it is working volume. What your closure, your product and your process each need from it, and what happens when you take it away.
Your filling method decides your headspace, your closure and your thermal shock margin. What each of the three routes asks of a glass bottle, and where each one fails.
A pasteuriser heats and cools your filled pack in stages, and glass has limits at every stage. How tunnel and batch differ, and what the differential does to your bottle.
A drop of liquid nitrogen displaces oxygen and stiffens a bottle. How dosing works, what it does for shelf life and lightweighting, and where it goes wrong on glass.
The capping head that applies your closure decides how repeatable your seal is. How chuck, magnetic and servo heads differ, and what a format changeover really involves.
A faster line scuffs, jams and breaks more glass. Where the damage happens, what coating and wall distribution do about it, and how to find your real speed ceiling.
Your labeller decides what your bottle has to give it. How wet glue, pressure sensitive and shrink sleeve machines differ, and which bottle geometry each one demands.
Switching bottle format is a job, not a dial. What changes at the conveyor, filler, capper and labeller, and how bottle choices cut your changeover time for years.
Finish designations, capacity and weight tolerances, and whether the glass bottle you shortlist runs on the filling line and capping head you already own.
Every neck finish a glass buyer meets, from GPI 24-410 to BVS 30×60 and the 26 H 180 crown, with the published T, E, I, H and S figures and the closure each one takes.
The 43-485 finish is the US spice-jar standard for sifter, shaker and flip-top caps. What it is, how it differs from 43-400, and the jars that carry it.
The vacuum lug finishes of ISO 9100, from 38 mm to 110 mm: which size suits your jar, what regular and deep change, and how you order a twist-off cap.
The tall 26 mm crown finish of ISO 12821: its bore, its crimping edge, how it differs from the shallow 26 H 126, and what your crown capper needs from the glass.
The BVS 30x60 screw finish for wine and spirits, dimension by dimension: thread, seal and locking-ring diameters, heights, bore and the ovality your capper needs.
FEA names the collar your fragrance pump crimps onto. What 13, 15, 17, 18 and 20 mean, crimp against screw, and the figures your pump supplier asks for first.
Regular mouth is 70-450G and wide mouth is 86-450G. What the 450 series does, why the G matters on glass, and which two-piece lids fit your jars.
38-400 is the most widely stocked wide-neck finish in food and beverage. What it carries, how it differs from 38 mm lug and DBJ necks, and which caps fit yours.
28-400 and 28-410 are two different bottles. The published T, E, I, H and S figures for each, what the extra half turn buys, and why the caps never interchange.
24-410 carries most lotion pumps, foamers and sprayers. Its published dimensions, what one and a half thread turns buy, and how to match a pump you already stock.
Nominal against brimful capacity, fill point, weight, verticality and finish flatness: seven figures on a glass bottle drawing, and the ISO standards behind them.
Three 18 mm necks take three different dropper caps. What separates the 400, 415 and DIN 18 finishes, and which one your pipette and tamper band were made for.
Bar-top stoppers, cork mouths and the bores behind them: the Cetie and EN standards, what pull force depends on, and how a spirits neck is specified.
A swing top has no thread and no series number. What the neck ring does, what the gasket does, and how a reusable bottle or jar is actually specified.
Nine checks that keep a cap from leaking on your line: finish designation and drawing, sealing surface and liner, torque, tamper band, fill and sample run.
A lug cap holds a vacuum in a quarter turn; a continuous thread seals on a liner. What each asks of your fill, your line and your consumer.
Cork, ROPP and crown are three different bottles. What each seals against, which capping head it needs, and where reseal, pressure and presentation decide.
Two ways to close a pressurised bottle. What a bail and gasket give you that a crimped crown cannot, and what they cost in speed and consistency.
The cap holds the liner; the liner holds the seal. What pulp, foam, plastisol, foil and EPE each do, which fills they suit, and how to put one on your specification.
Torque is where a good cap and a good bottle still fail. What application and removal torque mean, why the number decays after capping, and how to set your window.
Tamper evidence has to show interference, not prevent it. How bands, shrink sleeves, induction seals and lug buttons work, and which one your market expects.
A vacuum jar seals as it cools, not as it closes. What creates the pressure difference, why the button pops, and the handling mistakes that lose your seal.
An induction head welds a foil membrane to your bottle in under a second. How the field heats the foil, what the sealing surface must give it, and why seals fail.
A child-resistant cap has to defeat a toddler and still open for an adult. How push-and-turn, squeeze-and-turn and snap-lock work, and what the test protocols measure.
A dispensing closure is a small machine on your bottle. How lotion pumps, fine-mist sprayers, droppers and trigger heads work, and what each needs from the glass.
A gasket is chosen by chemistry and temperature, not by looks. What silicone, EPDM, natural rubber and cured plastisol each survive, and where they fail on glass.
Convert a bottle volume between millilitres and both fluid ounces, and see the nearest trade format. The full conversion table renders whether the converter runs or not.
Filter the common finish designations by the closure you hold or the diameter stamped on it. The full table renders whether the filter runs or not.
Add the prototype, sample mould and production tooling for a cavity count you choose. The published stage prices render whether the estimator runs or not.
Frosting, spray coating, screen printing, hot stamping, electroplating and labelling on glass, and what each process asks of your artwork, your minimum and your budget.
Frosting, spray coating, screen printing, decals, hot stamping, electroplating and labelling on glass bottles: what each survives and what it asks of your artwork.
A fired ceramic print is part of the glass; a label sits on it. Durability, cost, colour, minimums and lead time compared for your decoration decision.
Raised lettering is cut into steel, not printed. How embossing depth, radius and draft work, what glass will and will not fill, and how to keep your logo legible.
Frosting is a surface change, not a coating. How acid etching, sandblasting and frost coatings differ, what each does to fingerprints, and which suits your artwork.
Spray coating puts colour on the outside of a finished bottle. How the layer goes on and cures, what it survives, and why it beats coloured glass on small runs.
Screen printing pushes ceramic ink through a mesh and fires it into the glass. How the passes work, what registration costs, and the artwork rules that decide the result.
A decal carries photographic artwork onto a bottle and fires it into the glass. How the transfer works, what it costs against screen printing, and when your art needs it.
Hot stamping presses metallic foil onto glass with a heated die. What it can and cannot reproduce, why the panel matters, and how it compares with a fired print.
Metallised glass looks like solid metal and weighs nothing extra. How vacuum metallising and electroplating differ, what the layer survives, and where it fails.
Most label failures are surface failures. How wet glue, pressure-sensitive film and shrink sleeves differ on glass, and why coatings change what your adhesive can do.
Artwork made for print fails on glass for predictable reasons. Vector formats, Pantone on a curve, minimum line weight, seam clearance and how to mark a proof.
From drawing to production glass mould in three priced stages, $500 acrylic, $1,200 sample mould and $1,200–2,200 production tooling, and the minimums that follow.
Nine steps of a custom glass bottle project, with cost and deliverable at each: drawing, $500 prototype, $1,200 sample mould, production tooling, first run, reorders.
Tooling, minimums, lead time and shelf differentiation compared. What a custom mould actually buys, and the four cases where an existing mould cannot serve.
A sketch is not a drawing and a render is not a model. What a glass mould shop needs in your file, which dimensions it must carry, and what happens when they are missing.
An acrylic model costs a fraction of a mould and answers the questions a drawing cannot. What a prototype settles, what it cannot tell you, and when to skip it.
A sample mould makes real bottles before production tooling is cut. What it proves about weight, wall and fit, what it costs, and why buyers try to skip it.
Two bottles of the same size can differ several times over in tooling cost. What shape, cavity count, finish, embossing and glass grade each add to your mould quotation.
One mould is one cavity, and cavities decide how fast your order can be made. How section count, cycle time and cavity count combine into a realistic delivery date.
Paying for tooling and owning it are different things. What ownership, exclusivity, an NDA and a transfer clause each cover, and what to agree before steel is cut.
Tooling wears from the first cycle. Which part goes first, what wear looks like on the glass you receive, and how a maintenance schedule protects your specification.
How each site inspects every glass bottle, what the six transit failure modes look like, and which certificate answers which customs or retailer request.
Internal pressure to ISO 7458, thermal shock to ISO 7459 and vertical load to ISO 8113: the methods, the figures the trade quotes, and how to write one into your order.
Critical, major and minor glass bottle defects, the AQL most buyers write into an order, the ISO 2859-1 sample sizes behind it, and what SGSBOTTLE checks before packing.
ISO 9001, the SGS FDA lead and cadmium report, EC 1935/2004, Proposition 65, RoHS and a CNAS report: what each glass packaging certificate covers, and what it does not.
A bottle that cools too fast breaks for no visible reason. What your annealing lehr does, how residual stress is graded in polarised light, and what to ask a supplier.
A polariscope turns invisible stress into colour. How the instrument works, what an annealing grade under ASTM C148 means, and how to read the number on your report.
Glass breaks from a temperature difference across its wall, not from heat itself. Where your process creates that gradient, how the test runs, and how to design it out.
Carbonated fills push outward for the life of the pack. How the two ISO 7458 methods differ, what a burst figure tells you, and how to specify pressure resistance.
A bottle at the base of a pallet carries the whole stack. How ISO 8113 measures vertical load, where the force actually goes, and what your stacking plan implies.
An AQL is only half a sampling plan. What inspection levels I, II and III change, how normal, tightened and reduced inspection switch, and what to write into your order.
An inspection agency verifies what a factory reports. What SGS, TUV and Bureau Veritas actually do on a glass order, what they cannot cover, and how to brief one.
A factory tour shows you what the host chooses. What to ask about furnaces, forming, the cold end, tooling and records, and which answers tell you the most.
Glass is inert, and buyers still need paperwork. What lead and cadmium testing covers, what an EC 1935/2004 declaration says, and which document each market wants.
Glass is inert and US paperwork still exists. What FDA food contact, Proposition 65, net quantity labelling, TTB fill standards and state deposit laws each ask of you.
The EU regulates the material, the quantity and the waste. What EC 1935/2004, nominal quantities, the e-mark, packaging waste rules and EPR each ask of a glass buyer.
UK rules started from EU law and have moved. What assimilated food-contact law, packaging EPR reporting, deposit schemes and weights legislation now ask of a glass buyer.
Canada regulates labelling more tightly than the material. What bilingual labelling, metric net quantity, food-contact review and provincial stewardship each require.
Australia runs food standards, trade measurement, a recycling label and state deposit schemes at once. What each asks of your glass, and where they hit your label panel.
Japan regulates hygiene, measurement and recycling separately, and expects precision in all three. What the Food Sanitation Act and labelling ask of your glass.
Mexico works through NOM standards, and front-of-pack warnings changed label design there. What NOM labelling, net content and alcohol rules do to your panel.
Brazil splits packaging oversight between health, metrology and waste policy, with MERCOSUR behind it. What ANVISA, INMETRO and reverse logistics each ask of your glass.
Collected glass and furnace-ready cullet are not the same thing. What happens between the bin and the batch, and why colour sorting decides the outcome.
A recycled content figure on your pack is a public claim. What pre and post-consumer mean, how mass balance works, and what evidence a regulator expects.
A deposit scheme turns your bottle into a returnable asset. What marking, standardisation, refill weight and recognition each demand, and what to fix before tooling.
Extended producer responsibility charges you by weight, every year you sell. Who the obligated party is, how fees are modulated, and what your reporting rests on.
Melting, chemistry and freight each contribute. Where the carbon in a glass bottle actually comes from, what cullet and fuel change, and which lever is yours.
Two life cycle assessments of the same bottle can disagree completely. What scope, functional unit, trips, allocation and sponsorship each do to a result you are shown.
How many glass bottles fill a 40HC, what bulk and palletised loading each cost you, and what moves the price between EXW and your warehouse door.
About 25,000 bottles of 750 ml (25 oz) in standard shapes, 22,000 irregular, 60,000 of 12 oz: the 40HC loading maths, bulk against pallets, and what moves landed cost.
Enter your bottle diameter, height and gram weight and read how many pieces a 40HC or 20GP holds. Worked examples render whether the calculator runs or not.
What each Incoterm moves from your side to ours, why containerised glass often ships FCA, and the six line items between a Chinese factory gate and your warehouse door.
Glass fills a container by weight long before it fills it by volume. How payload limits, tare weight and VGM decide your container choice, and when a 20GP wins.
Incoterms divide cost, risk and paperwork between you and your supplier. What all 11 rules cover, which four apply to sea freight only, and how to write one correctly.
Bulk loading fits more glass in a container; pallets get it out faster and safer. What each costs you in count, labour, damage and unloading time.
Most transit damage starts inside the carton. What partitions, pads, trays, board grade and pieces per carton each do, and how to write them into your order.
Broken glass on arrival is a question of proof, not opinion. What actually causes transit damage, what evidence a claim needs, and when to open the container.
Glass containers classify under heading 7010. What the subheadings cover, why the code drives your duty rate, and the documents that clear a container without delay.
Freight rates move, sailings fill and peak season arrives every year. What booking, transit time, season and demurrage each do to a glass order, and how to plan them.
Every gram in your bottle ships twice and gets paid for every year. How glass weight moves container count, freight, recovery fees and shelf impression at once.
Approximate counts for a 40HC. The loading plan for your exact shape and carton comes with the quote, before you book freight.
| Container | Product | Approximate capacity |
|---|---|---|
| 40HC | 750 ml (25 oz) bottles, standard shapes | ≈ 25,000 pcs |
| 40HC | 750 ml (25 oz) bottles, irregular shapes | ≈ 22,000 pcs |
| 40HC | 12 oz (355 ml) bottles | ≈ 60,000 pcs |
A first order rarely fills a container with one shape: food jars, sauce bottles and candle glass load together, and the plan for your SKUs comes before you book freight. Heavier glass and irregular silhouettes lower the count. Landed-cost notes on the products page →

Yes. The 2026 catalogue covers every stock category with capacities in ml and oz, finishes and colours, and goes out by email within one business day until the download link is live.
Yes. Every quotation carries the finish drawing, so your closure supplier confirms the match on paper before you commit a container to it, and a sample of your existing cap comes back matched to the stock finishes that fit.
Yes, on request. Every batch gets a polariscope check at the site as routine; the written report is not part of the standard shipping documents, and it joins your paperwork when you ask for it at order stage.
Yes. Stock samples are free, and a custom project's decorated samples come off the sample mould at the $1,200 stage, 5–10 pieces in the decoration you sign off.
No tooling minimum on existing moulds: your first order is a pallet if that is all you need, and a container when you scale. Custom moulds start at 12,000 pieces in extra-flint or 50,000 in standard flint, the numbers we quote your competitors too.
