Problems solved by technology

[0003] In the preparation of masterbatches, polyolefin wax is generally added as a dispersant. If the amount of dispersant is too small, the pigment will be dispersed unevenly. If the amount of dispersant is too large, it will be difficult to process and shape, which will affect the dimensional stability of the product and lead to poor performance.
The amount of dispersant is difficult to control accurately, therefore, the existing polyolefin color plastic products are difficult to meet the requirements in terms of transparency and color uniformity

Abstract

The invention discloses a high-barrier colorful plastic product capable of retarding moisture and air. The plastic product is prepared from the following substances in percentage by weight: 70-90 percent of polyolefin, 7-20 percent of a high-barrier material, 2-5 percent of maleic anhydride-styrene solid resin, 0.4-5 percent of pigment, 0-3 percent of filler, and 0-2 percent of auxiliaries. According to the invention, the maleic anhydride-styrene solid resin can be used for improving the compatibility of non-polar polyolefin and polar high-barrier material, and enables the pigment, the filler and other powdered bodies to have excellent disperse performance. The plastic product has excellent uniformity and barrier performance, has the advantages of uniform color, smooth surface, good printing performance and the like, and is applicable to drink, food and medicine package.

Description

technical field [0001] The invention relates to a plastic product for packaging, more specifically, to a high-barrier color plastic product with moisture and gas resistance, which can be used for packaging of beverages, food and medicine. Background technique [0002] As a widely used packaging material, polyolefin has good moisture barrier properties, but poor gas barrier properties. In order to make up for the defect of poor gas barrier properties of general polyolefin materials, the main methods adopted are multi-layer compounding and blending modification. Multi-layer composite means that when manufacturing polyolefin packaging materials (such as polyolefin bottles and other containers), the container wall is made into a multi-layer structure, and a polymer material barrier layer with better barrier properties is compounded in the middle of the polyolefin layer. , but due to the complex manufacturing process of the material of the multilayer structure, the production co...
