wholesale plastic jars with lids

Food and personal-care fill

Creams, scrubs and condiments care about neck finish, liner and whether the jar will see hot fill. Food-contact and migration testing files are requested only for the named resin and lot. This desk does not treat a catalog PET jar as already approved for every fill.

Glass versus plastic is an open trade-off on aroma-sensitive or premium contact packs. Glass can fit inert-contact presentation; plastic can cut shipping weight and breakage. The buyer states which path is allowed before factories quote an alternative construction.

Industrial chemical pack

Solvent or surfactant fills often move from clear PET to HDPE. A food-contact jar and a chemical residue jar cannot share the same mold history without a written wipe-down or dedicated-tooling note. Burst strength of the shipper carton (for example 32 ECT single-wall or 275 lb burst double-wall) is a pack-out line, not a jar body spec. Flute profile and paperboard caliper belong on the outer carton, not on the jar drawing.

Line trial and ship-to rules

Capper chuck, labeler height and case-pack pattern change when wall thickness or lid height changes. Destination state rules and requested delivery date belong on the same RFQ as the jar. Incoming quality reviewers should name which documents they will check before the first receipt.
