Embodiment 1

[0017] The raw material for the production of non-slip plastic film base is: high-pressure polyethylene:

[0018] The materials used to produce the anti-slip layer are prepared in the following proportions

[0019] Polyolefin 70% Co-blowing agent 2%

[0020] AC blowing agent 10% polyethylene wax 5%

[0021] Calcium stearate 2% Accelerator DZ 3%

[0022] Zinc stearate 8%

[0023] During production, it is implemented according to the following process:

[0024] The high-pressure polyethylene is arch-extruded through a plastic extruder to the inner polymer channel of the special die to extrude the feed inlet 8, and the non-slip plastic film base is formed from the outlet after heating.

[0025] The material formed by uniform mixing according to the above ratio is arched from another plastic extruder to the anti-skid layer material of the special mold to extrude the feed inlet 9, after heating, the surface of the non-slip plastic film base is covered by the outlet to form an irregular...

Embodiment 2

[0028] The non-slip plastic film base is made of polyolefin.

[0029] The materials used to produce the anti-slip layer are prepared in the following proportions:

[0030] Polyolefin 70% white oil 5%

[0031] Foaming spirit 15% accelerator DZ 2%

[0032] Zinc stearate 3% Accelerator ZDC 3%

[0033] Co-foaming agent spicy 2%

[0034] During implementation, follow the process flow described in the first embodiment.

Embodiment 3

[0036] The non-slip plastic film base adopts: polyolefin.

[0037] The materials used to produce the anti-slip layer are prepared in the following proportions:

[0038] Polyolefin 70% Polyethylene fat 5%

[0039] Foaming agent H 10% Co-foaming agent 2%

[0040] Calcium stearate 2% Accelerator DZ 1%

[0041] Zinc stearate 8% Accelerator ZDC 2%

[0042] During implementation, follow the process flow described in the first embodiment.

Abstract

The present invention relates to a production process of antiskid plastic film and its special-purpose mould. Its production process includes the following steps: using plastic extruding machine to press polymer into inner layer channel of special-purpose mould, heating and extruding to form antiskid plastic film base; using another plastic extruding machine to press prepared antiskid material into outer layer antiskid material channel of the special-purpose mould, heating, extruding to stick the antiskid material over the plastic film base, finally cooling by airing and setting so as to obtain the invented product. Its special-purpose mould includes main mould core, main mould body, cover plate and lower mould body, etc.

Description

Technical field [0001] The invention relates to a plastic film production process and its mold, in particular to a non-slip plastic film production process and its special mold. Background technique [0002] Plastic film is a very versatile product. In traditional plastic film, the polymer is usually extruded from a plastic extruder into a mold. The polymer in the mold is heated and melted into a gel in the mold. The mold outlet is cooled by blowing and then drawn by the film blowing auxiliary machine to form. The traditional mold used generally has only a single material channel. The plastic film produced by the above process and mold is smooth on both sides. The packaging bag produced with this kind of plastic film, because the two sides are smooth, often limits the height of the packaging. In production, the plastic film is heated and knurled to increase its anti-slip function. However, this heating knurling process is not only complicated, but also affects the tensile stre...
