Processing method of food/drug container, materials for food/drug container and food/drug container

Abstract

Aiming at the shortage that hazardous substances are liable to ooze when a food / drug container in the prior art is heated or under an acid-base environment, the invention provides a processing method of the food / drug container, materials for the food / drug container and the food / drug container. The processing method comprises the steps that a manufactured container body is placed in a reaction cavity of atomic layer deposition equipment, metallic oxide deposition is conducted on at least the inner surface of the container body, and a metallic oxide air resisting layer is obtained on at least the inner surface of the container body. According to the processing method, the saving materials for the food / drug container and the food / drug container, the metallic oxide air resisting layer is arranged on at least the inner surface of the container body, therefore contact of foods or drugs with the container body can be isolated, and the situation that the hazardous substances oozed form the container body pollute the foods / drugs can be prevented.

Description

technical field [0001] The present invention relates to the field of daily necessities, and more specifically, relates to a processing method of a food / drug container, a material used for the food / drug container, and a food / drug container. Background technique [0002] At present, in our country, there are many kinds of food, including milk bags and milk boxes for liquid milk, beverage bottles for mineral water and beverages, wine barrels for wine, oil barrels for cooking oil, disposable fast food boxes, Disposable cups, canned bottles, solid food containers, the materials of these containers are divided into two categories, one is made of pure plastic and starch board, such as wine barrels, oil barrels, beverage bottles, some canned bottles, condiments Bottles, disposable plastic cups and disposable plastic lunch boxes, baby bottles, space cups, kettles, etc. The main raw material of these containers is plastic, the main raw material of disposable starch lunch boxes is star...

Problems solved by technology

The packaging container with this structure, the bottom plate is made of hard sheets such as polyvinyl chloride and polyvinylidene chloride. If polyvinyl chloride and polyvinylidene chloride are used for a long time to hold medicines, especially tablet medicines, the harmful ingredients contained in them are also There will be a certain degree of leakage, which will affect the quality and safety of drugs, especially for drugs that need to be stored at low temperature, the harm is more obvious; in addition, although these materials are resistant to moisture, water vapor, gas, light, aroma, odor, heat, etc. It has a certain blocking effect, but the air-tight performance is not ideal, and there will be moisture, odor, etc. absorbed by the drug through polyvinyl chloride and polyvinylidene chloride, which reduces the shelf life and efficacy of the drug
