Shandong foam packaging quality assurance Which? Jinan sail electronics industry preferred [] bubble wrap, put it simply, is to use foam to make packaging. Commonly referred to as bubble wrap, mainly it refers expandable polystyrene (EPS) raw materials made through the mold by heat, produced packaging products, commonly known as the "bubble." Polystyrene is an ideal packaging material, by molding process, can be processed into various shapes according to needs, different thickness of packaging products. At higher loads, the material through the deformation, energy absorption, decomposition and other energy to cushion, damping effect, but also has thermal insulation function. EPS packaging products is generally white, according to the requirements to produce color. The main use of features: 1, light. EPS packaging products replaced part of the space for the gas, per cubic decimeter volume contains 300-600 million independent sealed bubble. So it bulky than the plastic several times to several times. 2, with the ability to absorb shock loads. When the impact load EPS packaging products, foam and compressed gas through the stagnation that external energy is consumed, the dissipation of foam with a smaller negative acceleration, gradual termination shock loads, it has good shock effect. 3, good insulation properties. Thermal conductivity of pure EPS thermal conductivity (108cal / mh ℃) and the thermal conductivity of air (about 90cal / mh ℃) weighted average. 4, good insulation properties. EPS insulation products mainly through two ways, one to absorb acoustic energy, reduce reflection and transmission; the second is to eliminate resonance and reduce noise. 5, anti-aging and corrosion. In addition to prolonged exposure to high-energy radiation, no significant aging products. Resistant to many chemicals, such as acid, alkali, methanol, lime, bitumen and the like. 6, anti-static properties. Since the EPS product has a low conductivity, so the friction is easy to produce their own live phenomenon, the product of the average user will not be affected. For high-precision electronic products, especially large-scale modern appliances manifold structural elements, you should use anti-static EPS products.
