What are the uses of foam boxes? Not just for sealing packaging

Foam boxes can be seen everywhere in daily life, but people do not understand the use of foam boxes. In fact, foam boxes can be used for many wonderful purposes besides packaging.

1、 Sealing packaging

The foam box is made of foam. Generally speaking, foam packaging is mainly made of EPS by expandable packaging, and the raw materials are made by mold thermal processing. The packaging products are commonly known as "foam". Through the molding process, foam packaging boxes can be processed into packaging products of various shapes and thicknesses according to needs.

Under the condition of high load, the foam packaging box is cushioned and damped by deformation, energy absorption, energy decomposition and other means, and has the functions of heat preservation and heat insulation. EPS packaging products are generally white, and colors can be produced according to requirements. The main characteristics of foam packaging box are light weight. foam packaging box has the ability to absorb impact load, good thermal insulation performance, and foam packaging box has good sound insulation performance, aging resistance, corrosion resistance, and anti-static performance.

2、 Containers of insulation materials

The heat transfer performance of foam material itself is low. In addition, the micropores in the foam material prevent the "convection heat conduction" effect of air circulation, so the foam box can play a good role in heat preservation. If the corresponding ice bag is placed in a foam box, it can be used as food, beverage, clean vegetables, seafood, dairy products, butter, chocolate, biological agents, vaccines, chemical raw materials and other products, which need low-temperature refrigerated transportation and various biological refrigeration reagents, such as solder paste, poultry drugs, pharmaceuticals, plasma, vaccines, aquatic products, poultry, ornamental fish and foreign trade fresh food.

3、 Recycling of waste foam boxes for vegetable planting and fish farming

In recent years, planting vegetables on balconies has become a popular lifestyle among urban residents. It is common to use plastic foam boxes as flower pots. But is it safe and healthy? Professionals said that the common foam boxes or plastic boxes are organic, relatively stable, and the polymer molecular structure is strong and huge. Even after exposure to natural high temperature, decomposition is extremely limited, and it is difficult for plant roots to absorb foam box substances. If foam or plastic is toxic, it may refer to additives in foam boxes or plastic boxes, or heavy metals and other toxic substances loaded in the factory. Generally, foam boxes used for fruits should be relatively safe. However, when growing vegetables, do not use discarded foam boxes to grow vegetables. The purpose of these waste foam boxes is not clear. During use, the box may be contaminated with harmful ingredients. Growing vegetables in this foam box is definitely harmful to your health. Staff remind that foam is easy to soften and decompose. Replace the foam box once a year to ensure soil safety and vegetable safety.

In addition to growing vegetables, many city residents also use foam boxes to raise fish. The foam box is expandable polystyrene, non-toxic at room temperature, and insoluble in water. However, experienced individuals indicate that they still need to use potassium permanganate to eliminate toxins before releasing fish.
