[0037] 12 parts of methacrylic acid-butadiene-styrene copolymer resin, (to improve the strength of the film)

[0038] 15 parts of polyethylene glycol stearate (it increases the flexibility of the film, and can reduce the amount of softener used and increase the stability of the preparation system)

[0039] 3 parts of sodium n-hexadecyl sulfate (surface modifier, maintain the clarity of the film).

[0040] The packaging film is prepared by casting method.

Embodiment 3

[0042] A silky high-strength packaging film is prepared from the following raw materials in parts by mass

[0043] PE resin 100 parts,

Abstract

The invention relates to a smooth type high-strength packaging film, which is characterized by being prepared from the following raw materials in parts by mass: 100 parts of PE (polyethylene) resin, 5 to 8 parts of plasticizer, 2 to 3 parts of heat stabilizer, 0.5 to 4 parts of lubricating agent, 10 to 14 parts of methacrylic acid-butadiene-styrene copolymer resin, and 8 to 18 parts of polyoxyethylene stearate. According to the smooth type high-strength packaging film provided by the invention, through adding the polyoxyethylene stearate, the flexibility of the film is increased, the usage amount of a softening agent can be reduced, and the stability of a preparation system is improved; meanwhile, the transparency of the film is maintained through adding a surface modifier.

Description

technical field [0001] The invention relates to a packaging film, in particular to a silky high-strength packaging film used for daily necessities and hardware products. It 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 contradiction ...
