Embodiment Construction

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

[0013] First, mix 65% LDPE2420H and 35% LLDPE920NT by weight percentage to make the outer layer raw material, stir 35% LDPE2420H and 65% LLDPE920NT to make the middle layer raw material by weight percentage Stir 25% of LDPE2426H, 25% of MDPE5401, 25% of LLDPE218W, and 25% of LLDPE920NT evenly to make the inner layer raw mix material, and then mix the outer layer raw mix material, middle layer raw mix material, inner layer raw mix material The materials are batched according to 30% of the outer layer, 40% of the middle layer and 30% of the inner layer. After the batching is completed, the film blowing machine equipped with automatic batching equipment can be blown to produce the required film.

[0014] The film provided by the invention has the characteristics of high surface smoothness, easy corona, and easy compounding, and can be combined with batching equipment to realiz...

Abstract

The invention relates to a thin film. The thin film comprises, by weight, 30% of an outer layer, 40% of a middle layer and 30% of an inner layer. The invention further provides a production method of the thin film. The production method includes the following steps of material mixing, batching and film blowing. The thin film has the advantages that the surface evenness is high, electric corona and composition are easy, and the continuous production can be achieved through a film blowing machine by combining batching equipment.

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...
