Low tear strength of PLA film
Problem Phenomenon
PLA film has insufficient tear strength and tears easily.
Cause Analysis
PLA molecular chains are rigid, extensibility is poor, and tearing propagates fast.
Solution
Blend with flexible polymers (PBAT, etc.) to increase tear strength.
Key Takeaway
PLA tear performance is a key indicator for flexible packaging applications.
