Abstract

The invention relates to a high-temperature resistant nano film which comprises the following three parts in parts by weight: 40 parts of an outer layer, 20 parts of a middle layer and 40 parts of an inner layer. High-temperature resistant ingredients are added into both the inner layer and the outer layer, so that the finished product can resist to high temperature than like products. The invention further provides a production method of the film, which comprises the following steps: step 1, mixing; step 2, batching; step 3, film blowing. The film provided by the invention has the characteristics of high surface evenness, easiness for corona and compounding, high strength and high-temperature resistance and can be continuously produced by a film blowing machine in combination with batching equipment.

Description

technical field [0001] The invention relates to the field of film production and processing, in particular to a high-temperature-resistant nano 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 re...
