What happens when the friction coefficient of PE plastic film becomes larger?
The film base itself smoothness bad; not with extrusion composite slip agent, sticky film extrusion PE, the friction coefficient is larger;
The above reasons will cause difficulties when pulling the material bag, bags and bags of different lengths have electric eye deviation, open issues is not good, when the gas nozzle for blowing open bag packing bag for a long time and stuck together.
The permeability of the adhesive to the inner surface affects the coefficient of friction on the surface of the base material, especially when the film is thin and the corona is over treated.
Mature temperature is too high, smooth agent in high temperature lose function, especially high temperature cooking bag, RCPP originally smooth bad, after high temperature long time ripening, friction coefficient is difficult to control.
