example 1

[0037] 45-55 parts by weight of homopolypropylene with a melt index of 3-4g / 10min, 45-55 parts by weight of high-density polyethylene with a melt index of 0.09-0.15g / 10min, 0.1 part by weight of peroxide, and 0.2-0.25 parts by weight of oxidation inhibitor % parts by weight. It is produced by mixing and extruding with a twin-screw extruder.

example 2

[0039] A composite resin composition was produced in the same manner as in Example 1, using 45 to 55 parts by weight of random copolymer of ethylene / 1-butene and 45 to 55 weight percent of high-density polyethylene (HDPE). The results are shown in Table 1.

example 3

[0041] Using 50-80 parts by weight of random copolymer of ethylene / 1-butene and 20-50 parts by weight of high-density polyethylene, the same method as Example 1 was used to prepare a composite resin composition. The results are shown in Table 1.

Abstract

The invention discloses a polyolefin resin composition with a lusterless characteristic. The composition comprises, by weight, 20 to 80% of a polypropylene random copolymer resin of homo-polypropylene or ethylene/1-butylene and 80 to 20% of a high density polyethylene resin. The polyolefin resin composition has the advantages of a low price and excellent performance; a film prepared from the polyolefin resin composition has excellent mechanical properties, heat resistance, resistance to chemical reagents and superior formability, can be used for food packaging and commodity packaging and as coating materials for other materials and is a lusterless biaxial drawing polypropylene film with the advantages of the lusterless characteristic, simple manufacturing and excellent processability.

Description

technical field [0001] The invention relates to the technical field of film materials, in particular to a polyolefin resin composition with matt properties. Background technique [0002] The packaging industry has relatively high requirements for transparent plastic films, such as biaxially oriented polypropylene films. The surface of the film in the present invention is not generally high-gloss but dull, so it has a unique texture. [0003] Recently, films with low surface gloss and soft touch are widely used as high value-added products, and are produced by casting. [0004] The conventional production methods of polyolefin film include blow molding and casting molding. Films produced by blow molding with a T-die or circular die have excellent impact strength and tear strength, and are relatively inexpensive in terms of equipment investment, so they are often used. However, because the material will be stretched by blow molding, the melt strength of the resin must reach...
