Problems solved by technology

[0003] Due to the different application ranges of the film, the required characteristics will be very different. In some packaging, the friction of the surface layer needs to be high, while the friction of the inner layer is small, and the strength requirement is high. There is no such thing as yet. A film that is easy to mass-produce, has high friction on the surface, low friction on the inner layer, and extremely high strength

Embodiment Construction

[0012] The present invention will be further described below in conjunction with specific embodiments.

[0013] First, mix 25% LDPETN00, 25% MDPE1018HA, 40% LLDPE0209AA, and 10% LLDPE120F by weight percentage to make the outer layer raw material, mix 23% MDPE2310, 12% LLDPE2230, 62 % LLDPE0209AA, 3% 075 masterbatch are stirred evenly to make the middle layer original mixed material, and 20%-30% N00, 10%-15% MDPE1018HA, 5%-10% MDPE5400, 20%- 30% MDPE1018FA, 40%-60% LLDPE0209AA, 16%-20% LLDPE120F are stirred evenly to make the inner layer raw material, and then the outer layer raw material, the middle layer raw material, and the inner layer raw material are mixed according to the weight percentage The materials are batched according to 23% of the outer layer, 52% of the middle layer and 25% of the inner layer. After the batching is completed, the film blowing machine equipped with automatic batching equipment can be used to produce the required film.

[0014] The film provided ...

Abstract

The invention relates to a film which comprises the following three parts by weight percentage: 23% of an outer layer, 52% of a middle layer and 25% of an inner layer. The invention further provides a production method of the film, which comprises the following steps of Step (1) mixing, Step (2) batching, and Step (3) blowing the film. The film has the characteristics of great surface layer friction force, small inner layer friction force and higher strength, and can be produced continuously by batching equipment via a film blowing machine.

Description

technical field [0001] The invention relates to the field of film production and processing, in particular to a film and a production method thereof. Background technique [0002] Blowing film (Blow Membrane) is a plastic processing method, which refers to a plastic processing technology in which plastic particles are heated and melted and then blown into a film. If it is a film blown out of new materials, the color is uniform and clean, and the finished product is stretched well. If the plastic particles made of recycled waste plastics are usually added with pigments when made into a film, the resulting film may be unevenly colored, brittle and easily broken, and the price is relatively low. The blown film materials produced by professional film blowing machines are suitable for various high-grade film packaging. This film can be widely used in light and heavy packaging due to its good barrier properties, freshness preservation, moisture resistance, frost resistance, oxyg...
