What are the characteristics and advantages of foam packaging

Foam packaging, also known as porous plastic, is made of resin as the main raw material. There are many gaps inside, with a structure similar to a combination of popcorn. There are usually two types of materials, hard and soft. The shape is determined by the mold. It is usually white and has the common characteristics of lightweight, waterproof, thermal insulation, and shock absorption. It is particularly suitable for packaging fragile or liquid items. Due to its low thermal conductivity, it is also used for fresh fruits and vegetables. Keep it fresh.Manufacturer of foam boxBriefly introduce its advantages.

Foam packaging can be divided into crystalline and amorphous forms: crystalline form, whose internal molecules are arranged orderly and closely connected, so it has better stability, higher heat resistance and higher strength. Contrary to uncertainty, molecular chains are dispersed and mechanical properties are poor.

At present, the mainstream foam packaging products on the market are generally soft, cheap and flexible, but most of them are flammable and have potential fire safety hazards. This new type of flame retardant foam has good flame retardancy due to the addition of flame retardant components, and greatly broadens its application range. However, due to the high price, the current acceptance is not high. The development and promotion of this product still require enterprises to strengthen their awareness of fire prevention.

The packaging time is short, and the foaming material can expand into a suitable packaging within ten seconds.

It takes up less space, saves storage space, and can foam about 10 kilograms of foam material for 1 meter.

Cost saving, high foaming rate, and lower unit volume cost than other packaging materials.

Good buffering effect, strict protection, and high rebound buffering ensure the safety of the product during transportation.
