After sealing ziplock warped reasons

Rongcheng Wujia Plastic Co.,Ltd | Updated: May 26, 2016

Cause ziplock bags after sealing warping may be inconsistent thickness of the composite film, heat sealing or heat sealing temperature is too high for too long, hot knife in longitudinal section, running track composite membrane is not straight. Or cooling and the curing time is insufficient, poor heat resistance of the surface of the base film. Complex process of composite substrate tension mismatch control, resulting in ziplock after aging stereotypes still residual stress, particularly when the composite thin film thickness is more prone to such failure.
