Insufficient heat seal strength of PLA film
ظاهرة المشكلة
The seal strength of PLA film after heat sealing is low.
تحليل الأسباب
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.
الحل
Precisely control the heat sealing temperature, time, and pressure; use a heat seal enhancing formulation.
الخلاصة الأساسية
The PLA heat sealing process window is narrow and needs precise control.
