Heat seal matching of PLA cup lid and cup body
Fenómeno del problema
The heat seal strength of the PLA cup lid and the PLA cup body is inconsistent.
Análisis de la causa
Although the upper and lower materials are both PLA, the formulation and thickness affect the heat sealing temperature window.
Solución
Adjust the heat sealing parameters (temperature, time, pressure) to match the specific combination.
Conclusión clave
PLA cup lid sealing needs to be optimized for the specific material pair.
