Abstract

The invention discloses a production process of a high-extensibility plastic packaging film, and belongs to the technical field of packaging films, and the production process comprises the following steps: 1, weighing raw materials in parts by weight; 2, drying the raw materials in a vacuum oven at 45 DEG C, then mixing, carrying out extrusion granulation in a twin-screw extruder at the temperature of 160 DEG C, blowing into cylindrical film bubbles by air compression, carrying out blow molding film forming in a film blowing auxiliary machine to form a film product, and finally cutting, separately rolling and packaging to obtain the high-extensibility plastic packaging film. The modified polypropylene carbonate is added, the modified polypropylene carbonate is obtained by mixing and extruding polypropylene carbonate, a modifier and auxiliary components, and the modifier plays a coupling role in a reaction process, so that a three-dimensional network structure is formed, and the mechanical property and chemical stability of the film are enhanced.

Description

technical field

[0001] The invention belongs to the technical field of packaging films, and in particular relates to a production process of highly extensible plastic packaging films. Background technique

[0002] Plastic packaging and plastic packaging products have the advantages of a wide variety, light weight and beauty, and are not easy to break. The development speed far exceeds that of traditional paper, metal, glass and other packaging materials, and their market share is increasing. Composite plastic flexible packaging has been widely used in daily life, food, medicine, chemical industry and other fields, and has been developed rapidly and widely used. But while this brings convenience to people, it has also brought increasingly serious environmental pollution problems. A large number of waste plastic films are not easily degraded in nature, causing great harm to the ecological environment. Among them, biodegradable plastic film refers to a polymer material that c...
