Problems solved by technology

[0004] Due to the different application ranges of the film, the required characteristics will be very different. For 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. At present, there is no A film that is easy to mass-produce, has high friction on the surface, low friction on the inner layer, and extremely high strength

specific Embodiment approach

[0014] A specific embodiment of the present invention: a film, including an outer layer on the top, a middle layer is arranged on the lower side of the outer layer, an inner layer is arranged on the lower side of the middle layer, and the outer layer is an electric corona layer made of a special material. The halo layer, the middle layer is a polypropylene interlayer made of polypropylene scraps, and the inner layer is a heat-sealing layer made of heat-sealing plastic.

[0015] A film processing technology, comprising the following steps:

[0016] 1) Mixing, according to the weight percentage of each component of the outer layer, middle layer and inner layer, each raw material is stirred evenly according to the specified ratio to make the original mixed material for later use;

[0017] 2) Batching, batching the raw materials prepared in step 1) according to the weight percentage of the outer layer, middle layer and inner layer;

[0018] 3) Blown film, using a blown film machi...

Abstract

The invention discloses a thin film which comprises an outer layer, a middle layer and an inner layer with the composition ratios being 23%, 52% and 25% respectively. The invention further provides a production method of the thin film. The method comprises steps as follows: step one, mixing; step two, batching; step three, film blowing. The thin film provided by the invention has the characteristics of high surface layer friction force, small lining layer friction force and extremely high strength, and in combination of batching equipment, continuous production can be realized by a film blowing machine.

Description

technical field [0001] The invention relates to the field of thin films, in particular to a thin film and a processing technology. Background technique [0002] A film is a thin, soft, transparent sheet. It is made of plastic, adhesive, rubber or other materials, but some existing films are produced using raw materials, which wastes a lot of raw materials and high production costs, especially heat-sealing films. [0003] 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 pr...
