[China Packaging Network] its traditional packaging has always been used in the earthquake-proof shockproof materials and foam shockproof materials, paper packaging materials in the industrial equipment requirements are high, environmental considerations, is not environmentally friendly, it's Poor pressure resistance, poor water resistance, paper packaging materials, the biggest drawback is that it is easy to damp, will play a certain degree of damage to the packaged product.
Compared with paper packaging, sponge packaging has higher strength, rigidity and hardness, good adhesion performance, good oil resistance, electrical insulation, etc., good water resistance, alkali resistance, and acid resistance. Sex, in general, is much better than paper packaging, but sponge packaging also has some disadvantages, such as easy chipping, and sometimes scratching.
The emergence of foam solves all the disadvantages of paper and sponge. The foam has high density, stronger liquid absorption, more toughness and elasticity, and good abrasion resistance. It will not scratch the wiped device and will not chip away. After the particles and liquid enter the foam hole, they will not fall out or be easily extruded. They have good locking ability, and have good buffering, shock resistance, heat insulation, moisture resistance, and chemical resistance.
In addition to packaging materials, foam is also commonly used in automobiles, air conditioners, refrigerators, freezers, household appliances, engineering refrigeration and refrigeration and freezing, and lining materials for skates, sports shoes, car seats, car interiors, etc. Shock-proof packaging for products.
