Embodiment 1

[0021] Such as figure 1 As shown, a low-friction coefficient high-barrier aluminum-coated film is formed by four-layer co-extrusion of a heat-sealing layer 1, a first core layer 2, a second core layer 3, and an aluminum-coated layer 4; The mass percentages of the heat-sealing layer 1, the first core layer 2, the second core layer 3, and the aluminum plating layer 4 are respectively: 21%, 30%, 30%, and 19%;

[0022] The material of the heat-sealing layer is formed by mixing ternary random copolymer polypropylene (PP) resin [ternary random copolymer resin 750M] and a modifier, and the amount of the modifier added is ternary random copolymer 10-15% of the mass of propylene (PP) resin;

[0023] The material of the first core layer adopts polypropylene resin (containing few low-molecular precipitates), and because the precipitates are few, the maintenance of the corona value of the base film and the adhesion of the follow-up aluminum layer have played a better effect;

[0024] Th...

Embodiment 2

[0038] Such as figure 1 As shown, it is basically the same as Example 1, except that: the material of the aluminum layer adopts ethylene-vinyl acetate (EVA) copolymer resin.

Uniform aluminum plating, high adhesion, excellent barrier after aluminum plating, high brightness. The heat seal strength of similar products in the market is 8N / 108 degrees, and the product of the present invention is 12N / 104 degrees. The coefficient of friction of similar products in the market is 0.6-0.8, and that of the product of the present invention is 0.3-0.4.

Embodiment 3

[0041] Such as figure 1 As shown, it is basically the same as Example 1, except that the modifier is Exxon FL3980.

[0042] The advantages of similar products in the market are as follows: the invention has good flatness, high gloss, high heat-sealing strength and low coefficient of friction. Uniform aluminum plating, high adhesion, excellent barrier after aluminum plating, high brightness. The heat seal strength of similar products in the market is 8N / 108 degrees, and the product of the present invention is 12N / 104 degrees. The coefficient of friction of similar products in the market is 0.6-0.8, and that of the product of the present invention is 0.3-0.4.

Abstract

The invention belongs to the technical field of aluminized films, and discloses a low-friction coefficient high-resistance aluminized film. The aluminized film is characterized by comprising a heat-seal layer, a first core layer, a second core layer and an aluminized layer which are arranged in sequence through four-layer co-extrusion casting the mass percentages of the heat-seal layer, the first core layer, the second core layer and the aluminized layer are 21%, 30%, 30% and 19% respectively; the heat-seal layer is made of ternary random copolymerization polypropylene (PP) resin and a modifying agent; the adding amount of the modifying agent is 10-15% of the mass of the ternary random copolymerization polypropylene (PP) resin; the first core layer is made of polypropylene resin; the second core layer is made of polypropylene resin; the aluminized layer is made of copolymer resin and a reinforcing agent; the adding amount of the reinforcing agent is 2-5% of the mass of the copolymer resin. The aluminized film prepared according to the method is relatively low in friction coefficient, and relatively high in heat-seal strength.

Description

technical field [0001] The invention belongs to the technical field of aluminized film, and in particular relates to a low-friction coefficient high-barrier aluminized film and a preparation method thereof. Background technique [0002] The friction coefficient of the existing aluminized film is still high, and the heat sealing strength (barrier property) is still weak. Contents of the invention [0003] The object of the present invention is to provide a low-friction coefficient high-barrier aluminized film and a preparation method thereof. The aluminized film prepared by the method has a low friction coefficient and high heat-sealing strength. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a low friction coefficient and high barrier aluminized film, which is characterized in that it consists of a heat-sealing layer, a first core layer, a second core layer, and an aluminized layer. It is formed by co-extruding f...
