11 kinds of blow film formulations come! Improve film performance!
Reduce the thermal seal temperature formula for blowing film machine The starting temperatures of various heat sealing films were as follows: LDPE 135 ° C, LLDPE 148 ° C, EVA (VA content of 7.5%) 107 ° C, EVA (VA content 12%) 93 ° C, EMA (methyl methacrylate) 79 ° C, EMAA (Vinyl methacrylic acid) 93 ° C, surledn121 ° C, EAA (vinyl acrylic acid) 93 ° C. The various resins have good compatibility, and the extrusion blown film or extruded in the extrusion can reduce the heat sealing temperature after mixing each other. Such as: LDPE + EVA (50% + 50%) LDPE (50%) + 50% EMA; LDPE70% + 30% EAA; LDPE70% + 30% EMAA. Improve the heat-sealed film with cold resistance or heat resistance The cold-resistant temperatures of various hot segments are as follows: EVA, EAA, EMAA can resist -65 ° C ~ -73 ° C, LLDPE can resist-68 ° C ~ -73 ° C, PC (polycarbonate) can be resistant to -65 ° C ~ -75 ° C, LDPE can resist -48 ° C ~ -50 ° C, MDPE can resist -42 ° C ~ -45 ° C, surleng can resist-38 ° C
