Foam packaging foam packaging design process is the use made of foam packaging. General bubble wrap is defined by the polystyrene processing of raw materials produced by the mold by hot foam packaging products. Abstract technique used for amenity, using abstract geometric patterns color or texture of the composition of the picture results, you need to text and packaging design packaging design packaging products to co-ordinate thinking generally produce white color. Polystyrene is the ideal packaging materials, foam insulation box Qingdao, through the molding process, can be processed into various shapes according to needs, different thickness of packaging products. At higher load conditions material can be decomposed by absorbing deformation energy to cushion the shock absorption and other effects, but also has insulation foam packaging function. Foam packaging foam material effect on theory, any type of thermoplastic foam can be used in rotational molding, but because of the special parts of its technology, the choice of materials have some special requirements. First, the foam incubator Weifang, because it is not pressed into indium, rotational molding foam material must have good liquidity to enable it to smoothly like a liquid inflow every corner of the mold cavity to obtain uniform wall thickness products. Secondly, since the rotational foam molding cycle is longer, material required to withstand higher temperatures, so it is better thermal stability. Finally, in order to be able to resist the pressure of the gas inside the bubble, plastic raw materials requires a certain amount of melt elasticity. If the melt elasticity is too small, foam insulation box Linyi bubble will burst, foam insulation box, affect the quality of air bubbles. Impact strength and toughness in the choice of material is a very important consideration, but also the main requirements rotomolding foamed article. To meet this requirement, which is widely used in rotomolding foaming process. In addition, polypropylene (PP), PVC plasticized powder, ethylene - vinyl acetate copolymer (EVA), ethylene - butyl acrylate copolymer (ECTFE) and nylon, ABS, ethylene - trifluoroethylene copolymer (which is equal to also used for special applications. prospects for the development of raw materials also includes polyphenylene ether (PPO), ABS and ABS- polycarbonate (pc) alloy, polyether ether ketone (PEEK), polyphenylene sulfide (PPS) and glass . reinforced nylon, etc. In recent years, the metallocene catalyst synthesis provides excellent PE rotomolding foamed material foam insulation box |. much foam | foam insulation foam box Rizhao from Shandong great Ltd provide foam insulation box. | much foam | foam insulation foam box Rizhao Shandong great Ltd.
