Insulation bags can be divided into two types, one is for personal and family use, and the other is commonly used for lunch bags and field trips and car trips; the other is used in industrial and service industries, such as fresh milk companies, wine companies and institutions, and so on. According to the structure, the industrial insulation bag can be divided into three layers, from the outside to the inside are strong tensile Oxford cloth, super-dense insulation cotton and aluminum foil bonded non-woven fabric, and the bottom is a very high-density extruded board with good thermal insulation and pressure resistance. enhance the load-bearing and heat preservation effect of the whole insulation bag.

In the seventh chapter, this chapter focuses on the upstream and downstream market situation of thermal insulation lunch bags, the upstream market analyzes the supply status of main raw materials and main suppliers of thermal insulation lunch bags, and the downstream market mainly analyzes the main application areas of thermal insulation lunch bags, consumption in each field and future growth potential.

The first chapter analyzes the characteristics, classification and application of the thermal insulation lunch bag industry, focusing on the comparison of the current development situation and development trend between China and the global market, as well as the present and future trend of supply and demand between China and the global market.

For a lunch bag, the capacity should be appropriate, the thermal insulation performance should be good, and the design should be ergonomic, easy to switch and easy to carry. Both models meet these requirements, but there are some differences in details that are suitable for different uses.

In the eighth chapter, this chapter analyzes the current situation and trend of import and export trade of thermal insulation lunch bags in China, focusing on the relationship among output, import, export and apparent consumption of thermal insulation lunch bags in China. as well as the favorable and unfavorable factors for the development of the domestic market in the future.

Each of them has its own applicable situation. From kindergarten to middle school, there are few places where children are provided with refrigerators to store food. At this time, you need an insulated lunch bag, and it is best to put an ice pack inside to keep the food at a temperature that does not spoil easily. Thermal insulation lunch bag usually uses zipper opening and closing, with thermal insulation lining, the internal space is relatively large. Compared with the bento box, it is lighter and more cost-effective, but it is only suitable for packaged food. If fresh food is packed, it needs the combination of fresh boxes or sealed bags.

The sixth chapter analyzes the output, price, output value (ten thousand yuan), share and the development trend of future products or technology of different types of thermal insulation lunch bags. At the same time, it analyzes the main product types in the global market, the product types in the Chinese market, and the price trends of different types of products.
