The protective function of foam packaging: a commodity has to go through multiple circulations before it can enter a shopping mall or other places and reach consumers. During this period, it needs to go through loading and unloading, transportation, inventory, display, sales and other links. In the storage and transportation process Among them, many external factors, such as impact, humidity, light, gas, bacteria and other factors, will threaten the safety of the product. The protection function is the basic function of the package, even if the product is not damaged by various external forces. Therefore, the structure of the package is consistent with Materials are very important to ensure the safety of commodities in the circulation process. Good foam packaging has better protection functions and can fully guarantee the safety of products in circulation.
The main raw material of the foam box is EPS, which is usually referred to as polystyrene, and the two are mainly different in density. Pure polystyrene foam board is not toxic, but polystyrene foam board needs to add plastic additives to improve some properties of polystyrene foam board. Foam boxes are mainly used for food, beverages, clean vegetables, seafood, dairy products, butter, chocolate, biological preparations, vaccines, chemical raw materials and other products that require low-temperature refrigeration and transportation. In low temperature conditions, the foam box will not release toxic substances. Using foam boxes as packaging materials is relatively safe, and EPS packaging products are easier to recycle and reuse, making them a good green packaging material.
Pay attention to the following points when storing foam boxes:
1. The foam box contains a flammable volatile foaming agent, so fire should be avoided during storage.
2. The storage place of the foam box should be cool and well ventilated. To prevent the foaming agent from escaping too quickly, maintain a proper magnification, the storage temperature should be below 25℃, and always keep ventilation.
3. The foam box should try to use raw materials first, and keep them fresh, in order to obtain stable operating conditions and good products.
