The invention discloses a modified PET tangle film and a manufacturing method thereof. The modified PET tangle film comprises the following raw materials in parts by weight: 10 to 20 parts of modifiedPET material, 4 to 6 parts of
polyamide resin, 3 to 4 parts of modified maleic resin, 1.6 to 2.4 parts of modified Dama resin, 1 to 2 parts of
erucyl amide, 2 to 3 parts of
propylene glycol monomethyl ether, 2 to 3 parts of
tributyl citrate, 1 to 2 parts of diacetone
diamine, 0.3 to 0.5 part of
styrene, 1 to 2 parts of
dioctyl sebacate, 0.2 to 0.4 part of
tricresyl phosphate, 2 to 4 parts of
aziridine, 0.1 to 0.2 part of
ammonium molybdate, 1 to 2 parts of isobutyl
methacrylate and 5 to 7 parts of
rosin resin. The manufacturing method comprises the following steps: mixing and
drying the aboveraw materials, plasticizing and melting, extruding to form a film sheet, performing rapid-cooling shaped on a cooling roller, preheating by a heating roller, performing longitudinal stretching of 1:(2-5) between a low-speed roller and a high-speed roller, shaping by a shaping roller,
cutting edges, rolling and performing aging treatment to obtain a finished product. The production efficiency andthe product performance of the modified PET tangle film can be greatly improved.
