1. The food vacuum bag type, thickness, and quality of the heat seal layer material have a decisive influence on the heat seal strength.
2. The effect of heat sealing temperature on heat seal strength is most direct.
3, Dried fruit bags to achieve the ideal heat seal strength, a certain amount of pressure is essential.
4. The heat sealing time is mainly determined by the speed of the Bags making machine.
5, if the seal after heat sealing is not good, not only will affect the appearance of weld flatness, but also have a certain impact on the heat seal strength.
6. The more heat seal times, the higher the heat seal strength.
7. The same structure and thickness of the composite film, the higher the peel strength between the composite layers, the greater the heat seal strength.
