Let me ask you a direct question,When was the last time an ice bag broke on your customer's counter, leaving a puddle of frustration?
If this sounds familiar, the real problem isn't ice - it's low-notch impact resistance in the bag's polymer structure.
3 hidden reasons your current PE ice bags lack toughness
Too much recycled content – Over 30% post-industrial regrind kills elongation at break.
No anti-freeze agents – Yes, PE needs special additives to stay flexible below -10°C.
Inconsistent sealing – A weak bottom seal fails long before the film itself.
At YingFei Pack, we custom engineer PE ice bags using a three-layer co-extrusion process:
Outer layer: High-gloss LDPE for printability
Middle layer: mPE + EVA copolymer for extreme flexibility
Inner layer: Food-grade LLDPE for direct ice contact safety
Result? Bags that stretch instead of shatter - even when dropped from 1 meter high full of cubed ice.
