reason:
Because of external effects such as friction or in the form of various energies such as kinetic energy, potential energy, thermal energy and chemical energy, the positive and negative electricity of atoms will be unbalanced.
Packaging solution: During secondary processing, add 3% sanitary anti-static agent into the inner PE film to avoid such problems. When receiving orders from customers, the packaging will fully understand the customer's product characteristics and the characteristics of the automatic filling production line, so as to achieve a targeted view and better meet customer requirements.
What should we do if the bag warps after heat sealing?
reason:
(1) The thickness of the composite film is inconsistent.
(2) The heat sealing temperature is too high or the heat sealing time is too long.
(3) In the longitudinal heat sealing knife section, the running track of the composite film is not straight.
(4) Insufficient cooling.
(5) The ripening time is not enough.
(6) The heat resistance of the surface substrate film is poor.
(7) The tension matching control of the composite substrate is improper during the composite process, resulting in residual stress after its curing and setting, especially when the thickness of the composite film is thin.
Solutions for packaging:
(1) Adjust the tension of the floating roll.
(2) The inner sealing base material with low temperature heat sealing property shall be selected.
(3) Adjust the heat seal temperature to a suitable temperature.
(4) Cool sufficiently.
(5) Fully ripen.
(6) Reselect the surface substrate film.
(7) Adjust the tension of each part of the composite processing equipment to make the shrinkage of the two composite substrates equal as far as possible.
