The consultation record · answer was conducted on December 17, 2021 to investigate and analyze the current use of food packaging in the market, and point out the existing problems and improvement methods. Hello, dear! I’ve seen your question here, and I’m trying to sort out the answers. I’ll give you a reply in five minutes. Please wait a minute ~ through the survey in the mall, it is found that the most used packaging materials are plastic and paper, followed by metal, glass and rubber; Electrical appliances are mostly made of foam plastics, and some gifts materials include fabrics, wood and ceramics. In the survey, we also found that the higher the price of goods, such as gift goods, the more exquisite the packaging is, and the cost of packaging materials is also higher, but the practical * is not as good as ordinary packaging materials, and it is not as good as other packaging materials in terms of environmental protection. Appendix: main types of packaging materials, commodity categories and application materials. Electrical appliances: paper, foam plastics; Daily necessities: paper, plastic, rubber, glass (less), metal (less); Food: paper, plastic, metal, glass; Beverages: paper, plastic, glass, metal; Clothing: paper, plastic, fabric; Fruits and vegetables: plastic; Audio and video: paper, plastic, rubber; Gifts: paper, metal, glass, plastic (less). (2) Consumers’ opinions through the survey, it is found that nearly 64% of respondents will consider the packaging of goods when purchasing goods, while others believe that packaging will not affect their purchase of goods. Nearly 67% of the 64% of the respondents who bought goods considering commodity packaging. 9% of the respondents chose products with exquisite packaging; The second is the goods with durable packaging, with nearly 30. 3% of respondents chose this item; The choice of packaging simple and environmental protection of packaging materials is only about 0. 9% of respondents. (3) The disposal of waste packaging materials found through investigation that nearly 85. 1% of the respondents will say that useless packaging materials will be directly thrown into the trash can; There are nearly 10. 9% of the respondents will leave these materials for use when necessary; Nearly 4% of respondents will return useless packaging materials to the recycling bin for recycling. Because most of the waste packaging materials are treated by biodegradation, and some of them are not easy to be biodegradated, So as to cause [white * pollution]. For alleviating [white * pollution] Some respondents believe that pollution sources can be controlled and the use of such harmful packaging materials can be reduced; Such materials can be recycled; Or use high technology, use chemical, physical and other methods to decompose it into harmless substances and then bury it in the soil; It was suggested that it is necessary to develop new environmentally friendly packaging materials to solve this problem The Dongpo meat of sanfengqiao in Wuxi, Jiangsu Province is very famous. Please analyze the required protective conditions according to the characteristics of the product and design its packaging accordingly X09, including determining the appropriate packaging technology and method, selecting the appropriate packaging materials, etc. 1.
