Abstract

The invention discloses a color master batch suitable for milk product packaging materials utilizing polypropylene as a base material. The color master batch contains the following components in partsby weight: 100-120 parts of polypropylene, 60-80 parts of pigments, 1-5 parts of an antibacterial agent, 1-5 parts of a lubricating agent and 0.1-0.2 part of a dispersing agent. A production processof the color master batch comprises the following steps: mixing, blending and extrusion granulation. By virtue of the cooperative use of polypropylene and the antibacterial agent, a polypropylene color master batch is endowed with excellent antibacterial property and high barrier property, the processing formation properties of the antibacterial agent, polypropylene and the pigments are enhanced,and meanwhile, the antibacterial agent is unlikely to migrate out, so that the produced polypropylene color master batch has durable antibacterial activity after being produced into a milk product package, and the quality of the mild products can be durably maintained.

Description

technical field [0001] The invention relates to a color masterbatch, in particular to a color masterbatch suitable for dairy product packaging materials with polypropylene as the base material. Background technique [0002] Polypropylene has the advantages of rich sources of raw materials, cheap price, easy molding and processing, good rigidity and excellent mechanical properties, heat resistance, chemical resistance, excellent comprehensive performance, non-toxic, recyclable, etc., and is widely used in Industries such as automobile industry, household appliances, industrial supporting materials, packaging, office supplies, medical supplies and daily necessities have become the fastest-growing varieties of general-purpose plastics. Among plastic products, one-shot polypropylene exterior trims are more energy-efficient and material-saving than traditional metal exterior trims. The non-polar characteristics of polypropylene molecules make its surface free energy and surface ...
