High-resistance anti-ultraviolet bottle for packaging and preparation method thereof

Abstract

The invention provides a high-resistance anti-ultraviolet bottle for packaging, which is characterized by consisting of an outer layer, a middle layer and an inner layer, wherein the outer layer consists of the following components in percentage by weight: 94-98 percent of high-density polyethylene and 2-6 percent of anti-ultraviolet master batches; the middle layer consists of the following components in percentage by weight: 50 percent of a high-resistance composite material and 50 percent of adhesive resin; and the inner layer is high-density polyethylene. The invention further provides a preparation process of the high-resistance anti-ultraviolet bottle for packaging. The high-resistance anti-ultraviolet bottle has the advantages of wide anti-ultraviolet range, excellent oxygen resistance, excellent moisture resistance and increase the falling strength and thermal change-resistant temperature of a packaging container.

Description

technical field [0001] The invention relates to a high-barrier anti-ultraviolet bottle for packaging and a preparation method thereof. Background technique [0002] In recent years, with the development of society and the advancement of science and technology, people's living standards have been continuously improved, and people have paid more and more attention to health. Consumers have also put forward new requirements for food shelf life. During the storage of food, due to the oxygen input from the outside of the packaging container, the oil, pigment and other components in the food are oxidized to produce peculiar smell, and the ultraviolet rays affect the natural and synthetic pigments and dyes, vitamins, and other substances in various food, beverage, medical and health care products. Grease, fatty acids and odors have adverse effects, while standard PET and other packaging materials such as glass, polypropylene, polyethylene allow UV light to pass through. In order ...

AI Technical Summary

Problems solved by technology

The preparation methods of polymer nanoclay composite materials mainly include monomer intercalation method, solution intercalation method and melt intercalation method, but their manufacturing costs are relatively high. At present, domestic development is still in its infancy, and many fields are still blank.

On the one hand, many plastic packaging materials in my country, especially food, require high-barrier materials that cannot meet the requirements of international market competition; on the other hand, domestic requirements for high-barrier packaging for food, etc. are getting higher and higher.
