Puncture Resistance in Flexible Packaging
Puncture resistance depends on product shape, film structure, seal design, case packing, and distribution handling.
The problem, framed.
Puncture failures don't announce themselves at the factory — they show up as one leaking bag on a store shelf and a quality complaint with your name on it. Puncture resistance is engineered, not hoped for.
What's actually going on.
Sharp contents (kibble, hard candy, hardware, dried pasta) attack film from inside; transit abrasion and handling attack from outside. Resistance comes from material choice — nylon-containing laminations excel — plus gauge, and the structure's ability to flex around a point load instead of tearing. Testing matters because puncture behavior varies with temperature and flex history.
