Buffer packaging material, that is to protect goods in the circulation process, not because of impact and vibration and damage, the implementation of the packaging is called buffer anti-vibration packaging.The goal of buffer packaging design is to ensure that the buffer system has the best buffer efficiency on the premise of meeting the requirements of packaging protection, so as to minimize the amount of buffer materials.The whole product, cushion liner material and packaging container is called buffer packaging system.
From the perspective of buffering packaging materials, the following categories are commonly used now:
1. EPS
EPS has become a widely used buffering material in modern times due to its good buffering and vibration absorbing properties. EPS has the advantages of light weight, easy processing, good protection performance, wide adaptability, low price and high quality, etc., but it also has the disadvantages of large volume, waste can not be naturally weathered, burning treatment will produce harmful gases, etc.Under the circumstance of serious environmental pollution and shortage of natural resources EPS has caused great attention to the environmental damage.Therefore, foam plastic will be gradually replaced by other environmental protection buffer materials.
2. EPE
EPE pearl cotton is a kind of environmental protection foaming material with buffering and anti-seismic ability. It is soft, light and elastic. It can absorb and disperse external impact force through bending, which overcomes the disadvantages of ordinary foaming gum such as fragile, deformation and poor recovery.At the same time, EPE has a series of excellent features of heat preservation, moisture proof, sound insulation, friction resistance, aging resistance, corrosion resistance and so on.Add special material,EPE pearl cotton, has remarkable anti - static performance.It is also an environmentally friendly material that can be recycled.Widely used in construction, mechanical and electrical engineering, high-grade furniture, household appliances, instruments and meters, process gifts, wood products, glass and ceramics, carpet sandwich, tourist bags, precision parts packaging and insulation and other fields.
3. Paper Cushioning Packaging Material
Paper cushioning packaging materials have been used for a long time.However, due to the advantages of EPS in price and performance, the development of paper cushioning packaging materials is limited.In recent years, the serious problem of environmental pollution has prompted people to turn their attention to the development of environmentally friendly cushioning packaging materials.Paper cushioning packaging materials are one of them.At present the market USES more paper buffer packaging materials corrugated board and honeycomb cardboard.Honeycomb cardboard in particular, is a very good performance of environmental protection paper buffer packaging materials.
4.Molded Pulp
Pulp molding with pulp (or waste paper) as the main raw material, pulping by crushing, seasoning, injection molding mold, dry.The raw material source of the product is rich, the production and the use process is pollution-free, the product weight is light, the compressive strength is big, the buffering performance is good and has the good recyclability. Pulp molding products have developed rapidly in China. However, due to their strength, they are only used in the buffering packaging of some small electronic products, fruits, eggs and other items, but not for the buffering packaging of heavier products.
