Official-source supplier research
Nominal capacity alone is not comparable. Dimensions, film type, gauge, color, printing, and case pack determine the usable product.
Garbage bags & poly bags
Fifteen suppliers per category were selected from official-site research. Every listed supplier has at least three high-confidence, source-linked public claims. Missing facts stay missing; a check means evidence was found, not that availability or fit is guaranteed.
01 / COMPARE
A check means the supplier's official source supports that dimension. A dash means we did not fill the gap by inference.

02 / DECIDE
Require actual dimensions and nominal film thickness on every quote. For downgauging proposals, request a sample load test before accepting savings.
HDPE, LDPE, LLDPE, recycled, and biomass blends behave differently at the same thickness.
Quote exact width, length, thickness, capacity, and folded format together.
Municipal, food, heavy-duty, and infectious-waste uses require different evidence and labeling.
Record recycled or biomass percentage and certification at SKU level.
Custom print, color, carton pack, MOQ, and repeat lead time should be separated.
03 / SPECIFY
Use the same inputs for every supplier. This prevents a low headline price from hiding a different material, finish, quantity, or delivery condition.
