Open choices
bulk plastic tubs
Close the specification choices that still block a comparable bulk plastic tubs 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 lid, paperboard strength of the shipper, lid finish and test files.
- Barrier
- Board strength
- Lid finish
- Test files
Fields that must be named before two replies can be compared
An 8 oz natural PP deli tub and a 1 gal HDPE gasket tub 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 or multilayer wall; a mono PP wall is not the usual leak path when the lid gasket is open | 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 |
| Lid finish | Lid diameter (for example 89 mm, 110 mm or 160 mm), snap versus tear-band, liner and gasket type | A stock-cavity sample priced as if it were a custom mold |
| Resin and color | PP, HDPE or PET; natural, white or pigmented; post-consumer recycled content with a named evidence file | A mixed resin 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
- Resin and liner data sheet for the quoted construction only.
- Lid-finish drawing in the same units used on the price line.
- Migration testing file when the tub holds food; the file must name the lot.
- Sample type: stock-cavity tub, first-article mold or filled line trial.
- Exclusions: tooling, colorant, freight and sample freight listed in the same currency.
Before accepting an alternative construction, verify that resin, capacity, lid finish and liner still match the filler or the formula. A cheaper 8 oz / 250 ml snap-lid tub is not automatically a substitute for a 1 gal / 3.8 L gasket tub. Write fill volume in ml or L, wall or lid-film thickness in μm or mil if a liner is quoted, and shipper strength as 32 ECT single-wall or a named burst value. A mono-material PP 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.
