Nowadays, people's living standards are constantly improving, and people's pursuit of quality of life is getting higher and higher, which also makes foam packaging and packaging bags more widely used. What are the main characteristics of foam packaging? What is the protection method for packaging bags? With these questions, follow Bian Xiao to understand it.

Main features of foam packaging

1. Lightweight. Part of the space in the packaging of expanded polystyrene products is replaced by gas, with 3-6 million independent sealed bubbles per cubic centimeter of volume.

2. Has the ability to absorb impact loads. When the foamed polystyrene packaging product is subjected to impact load, the gas in the foam is consumed and dissipated through stagnation and compression, and the foam body gradually terminates the impact load with a small negative acceleration, so that it has a better shockproof effect.

3. Good insulation performance. The thermal conductivity is the weighted average of pure EPS thermal conductivity and air thermal conductivity.

4. Good sound insulation performance. EPS products are mainly soundproofed in two ways: firstly, they absorb sound energy and reduce reflection and transmission; The second is to eliminate resonance and reduce noise.

5. Anti aging and corrosion resistance. Except for long-term exposure to high-energy radiation, there is no obvious aging phenomenon of the product. Can withstand many chemical substances, such as dilute acid, dilute alkali, methanol, lime, asphalt, etc.

Protection methods for packaging bags

1. Due to the significant impact of temperature on vacuum packaging bags, remember not to place them in areas where direct sunlight can reach them, as strong ultraviolet radiation can accelerate the aging of vacuum packaging bags.

2. Vacuum packaging bags must avoid sudden heat and cold as much as possible to prevent thermal expansion and cold shrinkage of vacuum packaging bags, thereby shortening their service life.

3. Remember not to place vacuum packaging bags in damp areas with no air circulation, as this can easily cause the packaging bags to rot and affect their use.

4. For some vacuum packaging bags that have not been used for a long time, please carefully check them for cracks before starting to use.

Foam packaging manufacturerThe main use characteristics of foam packaging and the protection methods of packaging bags were introduced. In normal use, we must remember this protection method so that your packaging bag can have a better service life.
