How to Spec Composite Paper Cans
Specify composite paper cans by barrier, rim, and closure—not by photo. Compare structures, sample seals, and RFQ China canister converters.
Quick answer
Specify composite paper cans from the product contact case outward: barrier needs, rim/closure type, label or print method, and drop/stack targets—not from a lifestyle render. The same outer diameter can hide very different liner and seal systems.
What should buyers freeze first?
Lock ID/OD/height, spiral or convolute build, liner/foil structure, and end closures (metal, paper, plastic). State food-contact or dry-goods only before artwork starts.
How do you validate the can as a system?
Approve production-process samples with fill, seal, label, and ship simulation. Bottom leaks and rim crush often appear only after real filling equipment runs.

When should you reject a quote?
Reject quotes that omit liner structure, seal method, or sample gates. Unit price without a frozen bill of materials is not comparable.
