Puncture-resistance nylon composite film

Abstract

The invention discloses a puncture-resistance nylon composite film. The puncture-resistance nylon composite film is prepared from, by weight, 60-70 parts of nylon, 15-20 parts of nitrocotton resin, 14-20 parts of corundum fine powder, 9-13 parts of melamine cyanurate, 6-12 parts of silicon carbide, 12-25 parts of boron carbide, 23-29 parts of glass fibers, 3-7 parts of aluminum oxide, 1-3 parts of titanium dioxide, 0.5-2 parts of antimonous oxide, 1-2 parts of benzoin ethyl ether, 7-9 parts of nanometer montmorillonite, 1.2-1.4 parts of tetrabutyl titanate, 12-14 parts of ramie stems, 2-3 parts of gelatin, 1-2 parts of magnesium stearate, 13-15 parts of acetyl tributyl citrate, 1-1.5 parts of 2,6-ditert-butyl-4-methylphenol, 4-6 parts of 3-hydroxybenzoic acid, 1-2 parts of lauryl sulfate and 4-6 parts of plant saponin. The nylon composite film prepared with the method has the quite-high puncture resistance, and is free of damage at a corner angle after being vacuumized and stretched, and therefore the higher oxygen resistance function, water resistance function and vapor resistance function can be kept; a quite-good packing material is provided for corner-angle products.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a puncture-resistant nylon composite film. Background technique [0002] With the progress of society, commodities also put forward higher and higher requirements for packaging. Many angular commodities such as trotters, steaks, chickens and geese, and electronic printed circuit boards are vacuum-packed. The corners of the nylon composite film are often damaged due to the stretching of the nylon layer, which affects the barrier performance of the package. Therefore, in addition to the oxygen barrier and water vapor barrier functions of the packaging film, the packaging of the product also requires that the packaging film at the edges and corners of the package should not be damaged after vacuum packaging of many angular products. This requires that the co-extruded composite film not only has the functions of oxygen barrier and water vapor barrier, but also has good puncture re...
