Multi-layer film material and its manufacturing method with gas leak detection watch box

摘要

The present invention is a gas that can visually detect the absence or gas leakage of the package by reacting with carbon dioxide contained in the packaging in a modified atmosphere packaging (MAP) used to extend the shelf life and marketability of fresh food Leak Detection Indicator Incorporation Multilayer Film Material, Electrical Gas Leak Detection Indicator Incorporation Method of Manufacturing Multilayer Film Material and Packaging Using It to Recognize Freshness of Contents without Changing the Package It is about a method. According to the packaging method using the gas leak detection indicator-embedded multilayer film material of the present invention, whether to control the environmental gas in the package without breaking the product package without going through cumbersome direct identification steps such as physicochemical and microbiological analysis of the contents It can be recognized by the color change of the indicator attached to the film itself.
