Insufficient heat seal strength of PLA film
문제 현상
The seal strength of PLA film after heat sealing is low.
원인 분석
The PLA heat sealing temperature window is narrow (between the start of melting and degradation) and the parameters are improper; the strength of the film itself is limited.
해결 방법
Precisely control the heat sealing temperature, time, and pressure; use a heat seal enhancing formulation.
핵심 요약
The PLA heat sealing process window is narrow and needs precise control.
