Open choices
glass jars manufacturer
Close the specification choices that still block a comparable glass jars manufacturer quote. This page reuses a compact header plus a data table and a document checklist. It is not an ESG scorecard and not a carbon report. The theme is barrier through the closure, paperboard strength of the shipper, neck finish and test files.
- Barrier
- Board strength
- Neck finish
- Test files
Fields that must be named before two replies can be compared
A 1 L flint pantry jar and a 250 ml wooden-lid gift jar can share artwork and still be different forming jobs. Put each open choice on its own row. Alternative constructions are acceptable only after the buyer verifies the fields that change.
| Field | What to write | What blocks a comparison |
|---|---|---|
| Barrier | Oxygen transmission rate and water vapor transmission rate for the named lid liner; glass walls are not the usual leak path | The word airtight without a liner construction or a test method |
| Board strength | Paperboard caliper for any printed inner carton; edge crush test or burst strength for the corrugated shipper | A marketing PDF treated as a locked carton die line |
| Neck finish | GCMI drawing (for example 70-400, 89-400 or 110 lug), liner and closure type | A stock-neck sample priced as if it were a custom mould |
| Glass color | Flint, amber or cobalt; cullet or post-consumer recycled content with a named evidence file | A mixed color family on one piece-price cell |
| Test files | Migration testing, food-contact or chemical-compatibility file that names the quoted lot | A category certificate reused as if it were this cavity |
Check an open pair before you accept a substitute
Documents to request, not badges this site wears
- Glass and liner data sheet for the quoted construction only.
- Neck-finish drawing in the same units used on the price line.
- Migration testing file when the jar holds food; the file must name the lot.
- Sample type: stock-neck jar, first-article mould or filled line trial.
- Exclusions: tooling, colorant, freight and sample freight listed in the same currency.
Before accepting an alternative construction, verify that glass color, capacity, neck finish and liner still match the filler or the formula. A cheaper 2 oz CT jar is not automatically a substitute for a 1 L wooden-lid gift jar. A mono-material glass body can help recycling reporting; a multilayer liner path may still be needed when oxygen transmission rate through the closure is the duty. That is the mono-versus-multilayer dispute in the industry notes, not a site-wide recyclability claim.
