Abstract

The invention discloses an environment-friendly beverage packaging bag which comprises the following raw materials in parts by weight: 50-60 parts of polybutylene succinate, 16-18 parts of polybutylene terephthalate adipate, 2.6-3.2 parts of modified chitosan, 2.2-2.5 parts of carbon nanotube whiskers, 1.8-2 parts of mica powder and 0.5-0.7 part of a coupling agent. The invention further disclosesa processing technology of the packaging bag. According to the invention, the copolymer of polybutylene succinate and polybutylene terephthalate adipate is used as the polymer matrix of the packagingbag, so that the polymer matrix not only meets the environment-friendly performance of easy degradation, but also has good mechanical properties and heat resistance. By adding modified chitosan and carbon nanotube whiskers and carrying out coupling agent treatment before blending with a polymer matrix, the environment-friendly packaging bag which is easy to degrade, high in mechanical property and barrier property and antibacterial is obtained, and the environment-friendly packaging bag is suitable for packaging beverages.

Description

technical field [0001] The invention belongs to the technical field of packaging bags, and in particular relates to an environment-friendly beverage packaging bag and a processing technology thereof. Background technique [0002] Food packaging is an integral part of food commodities, which can prevent the damage of biological, chemical and physical external factors during the circulation of food from the factory to the hands of consumers. The food industry has always shown great interest in developing packaging of different materials, and the development of new packaging technologies helps to improve the quality and safety of food. For beverage packaging, the more common ones are bottled, canned, boxed, bagged, etc. Beverage packaging bags are widely used because of their low cost, small size, light weight, and portability. Beverage packaging bags are generally made of plastic, or a layer of functional paint is coated on the inner surface of the plastic. Ordinary plastics ...
