Abstract

The invention relates to the field of processing of macromolecular compounds, in particular to a film blowing material and a preparation method thereof. The material special for blowing a packaging film comprises a composite blowing material, wherein the composite blowing material comprises carrier resin, inorganic powder, a toughening agent, a dispersing agent, a lubricating agent, a coupling agent and a stabilizer. The preparation method for the material special for blowing the packaging film comprises the following steps of: 1) mixing the composite blowing material; and 2) performing extrusion granulation on the mixture. Through the technical scheme, the composite blowing material has the obvious advantages that cost is low, dispersion points do not exist on the surface of a film-coated product, and the like.

Description

technical field

[0001] The invention relates to the field of polymer compound processing, in particular to a blown film material and a manufacturing method. Background technique

[0002] Traditional shopping bags or packaging films are generally prepared by blending and blow molding of polyolefin resin and a small amount of filler material prepared by inorganic powder. Traditional shopping bags or packaging films are relatively complicated in technology and need to be formulated strictly according to a certain ratio. And in the preparation process, a special stirring link is required for stirring. In addition, the amount of filler material added is relatively small, and the general amount added does not exceed 30% of the total amount of blow molding materials, so the effect of cost reduction is not obvious. Contents of the invention

[0003] The object of the present invention is to provide a special material for blown film for packaging to solve the above technical prob...
