Abstract

The invention discloses a packaging winding film, which is prepared from acrylonitrile-butadiene-styrene, aramid fiber, surface modified mineral fiber, polyurethane, a plasticizer and a stabilizer as the raw materials. Specifically, the surface modified mineral fiber is prepared by adding TES into chloroform with suspending mineral fiber, and conducting shocking, standing, washing and drying. The packaging winding film is prepared by mechanical mixing, double-screw high temperature extrusion, and film casting by virtue of a melt casting machine. The packaging winding film provided by the invention has the advantages of simple preparation process, low cost, excellent tensile performance and penetration resistance, and excellent self-adhesion.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and relates to a film material, in particular to a packaging wrapping film. Background technique [0002] With the development of the economy and the progress of the society, there is an increasing demand for various stretch wrap films in bundling, packaging and wrapping operations. Stretch film has the characteristics of good tensile performance, tear resistance, strong penetration resistance, high transparency, good self-adhesiveness, high shrinkage rate, tight packaging and no looseness. It has been widely used in domestic and foreign packaging markets in recent years. Involving chemical products, electronic product boxes, ceramic products, mechanical and electrical equipment and other packaging and bundling applications. [0003] At present, the conventional stretch film used in the market is mostly processed by extrusion process, and its main raw materials are polyvinyl chloride...
