Processing Guide

● Only single use 338 series extruder reference setting temperature: extrusion section 90℃-165℃, mold die : 150℃-165℃, customers need to adjust the processing parameters according to their own co-extrusion film blowing machine set, base film formula, product usage;
● Control the ratio of adhesive layer extrusion or with other polyolefin used to adjust the adhesion of the protective film, with other adhensity-reducing materials need to adjust the extruder and die head temperature according to the different types of materials, fluidity, and processing temperature;
● In order to avoid bridging the material at the feeding port, the temperature of the feeding area must be kept below 70℃, and it is recommended that the feeding area be cooled by cold water to control the temperature;Especially in summer!

● Customers who use these products, and need technical support can consult our company personnel
