PBAT shopping bag strength
Problem Phenomenon
PBAT shopping bags have insufficient load-bearing capacity, handles break, and consumers complain.
Cause Analysis
PBAT strength is low; bag shape design; handle structure; thickness distribution; loading weight.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Blending reinforcement; ②bag shape structure optimization; ③handle reinforcement; ④uniform thickness; ⑤load-bearing test.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PBAT shopping bag strength is user experience; structure and material are equally important; testing ensures quality.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
