Abstract

The invention relates to the field of plastic making and in particular to a modified film for packaging alcohols and drinks and a preparation method of the modified film. The modified film for packaging alcohols and drinks comprises the following components in parts by weight: 100 parts of polyvinyl chloride resin powder, 1.5 parts of a stabilizer, 9 parts of a reinforcing agent, 1.2 parts of processing aids, 5 parts of a plasticizer, 0.35 part of aluminum powder and 0.8 part of a lubricating agent. Due to synergism of different components of the modified film for packaging alcohols and drinks, the obtained film can be shrunk, is good in sealing property, relatively uniform in longitudinal and transverse shrinkage rate, low in cost and low in price. The modified film prepared by using thepreparation method provided by the invention has a dull polish effect and a metallic color, and can meet market requirements.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to a modified film used for packaging alcoholic beverages and a preparation method thereof. Background technique [0002] Red wine is very sensitive to oxygen, and an irreversible chemical reaction will occur when it encounters oxygen. Excessive oxygen will make the flavor of the wine disappear in a short time. At present, the material used for the outer packaging of red wine bottle caps is mainly aluminum foil. The production process and purity of aluminum foil are destined to have pinholes and trachoma, and pinholes and trachoma are channels for oxygen, and aluminum foil is low in strength and easy to tear. It is easy to break when folded, resulting in holes. In addition, aluminum foil is a metal with poor durability, so it is prone to cracks that are not easy to find with the naked eye. Such cracks are also one of the channels for oxygen. [0003] In 2010, the applicant applied...
