Embodiment 1
[0017] A preparation process of a plastic film is characterized in that the ingredients of the plastic film are: the polypropylene component is 55-95%, the maleic anhydride graft modified product component of polyolefin is 2-30%, and the masterbatch component is 2-30%. Divided into 0.5-30%,
[0018] The anti-sticking agent component contained in the agent masterbatch is 0-2%, the antistatic agent component is 0-5%, the matting masterbatch component is 0-20%, and the titanium dioxide and calcium carbonate components are 0-20%. 20%.
[0019] A kind of preparation technology of plastic film comprises the following steps:
[0020] Put the ingredients into the corresponding extruder for melting and plasticizing at 180°C-280°C, extrude and confluence in T-shaped or hanger-shaped die, and extrude through the die at 180°C-280°C;
[0021] Cool the die extruded product of the support layer through a cooling device at 10°C-60°C to form a membrane;
[0022] The film is preheated, stret...

The invention discloses a preparation process for a plastic film. The preparation process is characterized in that the plastic film is prepared from 55%-95% of a polypropylene component, 2%-30% of a polyolefin maleic anhydride graft modifier component, 0.5%-30% of an agent master batch component, and the agent master bath component comprises 0%-2% of an anti-binding agent component, 0%-5% of an antistatic agent component, 0%-20% of an extinction master batch component and 0%-20% of a titanium dioxide and calcium carbonate component. The plastic film has the beneficial effects that the plasticfilm is a stretchable film which is wider in applicability, lower in cost and capable of achieving low-temperature heat sealing between paper and the plastic film or between plastic films, and when the film is combined with the paper or other films, combination can be completed through contact between a low-temperature heat seal layer and the object to be combined without glue coating, and no toxic gas is generated in combination.
Description
technical field [0001] The invention relates to a preparation process of a plastic film. Background technique [0002] At present, the paper-plastic structure has poor adaptability to paper, narrow application range, and high processing cost of glue-free composite film. As an important part of chemical building materials, material pipes are widely used in the fields of building water supply and drainage, urban water supply and drainage, and gas pipes because of their advantages such as small water loss, energy saving, material saving, ecological protection, and convenient completion, and have become urban construction pipes in the new century. The main force of the network. With the continuous improvement of consumers' quality requirements for product environmental protection, health, durability, etc., while the output of my country's plastic pipes is increasing, the product quality level is continuously improving, the technological progress of the industry is accelerating,...
