Foam box is a box type packaging container made of foamed plastic (porous plastic). Plastic foam is a plastic with many tiny pores inside. Foam boxes are often used in the transportation of fruits and the packaging of goods.

Expandable polystyrene foam is a new type of shockproof packaging material and thermal insulation material. It has the advantages of light weight, impact resistance, easy forming, beautiful appearance, bright color, high efficiency and energy conservation, low price, and wide range of applications. EPS foam parts are excellent packaging materials, such as televisions, refrigerators, washing machines, air conditioners, electronic instruments, precision instruments, glassware, ceramic products, art and craft products, all of which cannot do without EPS foam parts as cushioning packaging materials. EPS foam plastic is a lightweight material made by heating and foaming polystyrene resin as the base material, adding foaming agent and other auxiliary materials. It has the advantages of light weight, low thermal conductivity, low water absorption, water resistance, aging resistance, low temperature resistance, easy processing, low price, and excellent quality. It is suitable for freezing seafood, preserving vegetables, and so onInsulation boxContainers of indispensable insulation and preservation materials for cold storage, refrigerated vehicles, railway passenger cars, etc. EPS packaging is relatively easy to recycle and reuse, making it a good green packaging material.

Before use, simply put the ice bag inside the refrigerator into a household refrigerator to fully freeze it, and then put the ice bag into a passive car refrigerator to cool it. It is very convenient to use and can generally maintain a low temperature for more than 72 hours. In winter, if the ice bag is fully heated in a microwave and then placed in a passive car refrigerator, it can also serve as insulation. This passive refrigerator avoids the noise generated by the compressor during operation, and also has the characteristics of energy-saving, environmentally friendly, noise free, lightweight and flexible semiconductor refrigerators, which is expected to occupy a place in the car refrigerator market.
