Problems solved by technology

[0003] Due to the disadvantages of traditional pulp paper production and the resource contradiction of wood pulp paper, it cannot meet the needs of the packaging industry with a wide variety and huge demand, let alone the needs of sustainable development of society
Especially at present, in order to meet the needs of packaging, traditional paper needs further surface coating treatment, and the existing packaging coatings have poor transparent and dry effects, which affects the use effect of packaging materials

Abstract

The invention relates to a degradable easy-to-print packaging film. The degradable easy-to-print packaging film is characterized by being prepared from the following raw materials in parts by weight: 100 parts of PVC resin, 5-8 parts of a plasticizer, 2-3 parts of a heat stabilizer, 0.5-4 parts of a lubricant, 1-3 parts of a softening agent, 6-8 parts of an organosilicone-aliphatic ester compound, 10-15 parts of polylactic acid and 1.5-5 parts of a surface modifier. The degradable easy-to-print packaging film is conducive to improvement of the transparency through adding the organosilicone-aliphatic ester compound, a smooth and dry film surface can be obtained and the film has excellent printing property.

Description

technical field [0001] The invention relates to a packaging film, in particular to a degradable and easy-to-print packaging film used for daily necessities and hardware products, and belongs to the technical field of daily necessities. Background technique [0002] With the extensive application of paper in packaging and other fields, the demand is increasing. In particular, the application of white cardboard in the packaging field includes medicines, health care products, cosmetics, electronic products, handbags, clothing boxes, toy boxes, cigarette packaging, paper cups, instant noodle boxes, hamburger boxes, pastry boxes and other food packaging. Paper jams have led to a sharp increase in the demand for white cardboard. At present, the rapid development of e-commerce and logistics has further promoted the surge in demand for packaging paper products such as cartons and cartons. [0003] Due to the disadvantages of traditional pulp paper production and the resource contr...
