Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-2, the present invention provides a plastic film with high tensile strength: including stretch-proofing layer 1, enhancement layer 2, protective layer 3, the fixed both sides that set up at stretch-proofing layer 1 of enhancement layer 2, protective layer 3 is fixed to be set up in one side that stretch-proofing layer 1 was kept away from at enhancement layer 2.

The stretch-resistant layer 1 is made of a biaxially oriented polypropylene film, and the thickness of the stretch-resistant layer 1 is 20-40 microns.

The biaxially oriented polypropylene film has the advantages of good physical stability, mechanical strength and air tightness, high transparency and glossiness, toughness and wear resistance, so that the film has good structural strength, and the thickness of the anti-stretching layer 1 is 20-40 microns, so that the film is high in transparency and glossiness, and simultaneously, the toughness and wear resistance are balanced.

Referring to fig. 1-2, the reinforcement layer 2 is made of EVA material. The thickness of the reinforcing layer 2 is 20 to 150 μm.

The film made of the EVA material has high strength and good anti-fogging and heat-insulating properties, the thickness of the reinforcing layer 2 is 20-150 microns, so that the strength and transparency of the film are balanced, and if the strength of the film is less than 20 microns, the strength of the film is insufficient, and if the thickness of the film exceeds 150 microns, the transparency is poor.

In addition, the reinforcing layer 2 is in a honeycomb net shape.

When the strength of the film is enhanced, the honeycomb reticular reinforced layer 2 can save materials and reduce cost, and meanwhile, the film has better toughness due to the honeycomb reticular reinforced layer 2.

Referring to fig. 1, the protective layer 3 is made of polyethylene material, and the thickness of the protective layer 3 is 30-80 μm.

The film made of the polyethylene material is glossy, soft in texture and excellent in chemical stability, heat sealability, water resistance and freezing resistance, the thickness of the protective layer 3 is 30-80 microns, so that the transparency, softness, water resistance and freezing resistance of the film are balanced, if the thickness is less than 30 microns, the water resistance and freezing resistance of the film are poor, and if the thickness exceeds 80 microns, the transparency and softness of the film are poor.

The stretch-resistant layer 1, the reinforcing layer 2, and the protective layer 3 are bonded and fixed by an adhesive.

The anti-stretching layer 1, the reinforcing layer 2 and the protective layer 3 are bonded and fixed through the adhesive, so that the film has good heat preservation, freezing resistance and structural strength.

Furthermore, a moisture-proof filling agent is arranged between the anti-stretching layer 1 and the protective layer 3, and the moisture-proof filling agent is arranged in the honeycomb net-shaped grids of the reinforcing layer 2.

And moisture-proof filler is filled between the tensile-resistant layer 1 and the protective layer 3, so that the film has good moisture resistance.
