To protect skin to taste in chaoyang packaging picture books

Protect skin to taste in chaoyang packaging picture books according to the food law, used in food, packaging shall be used for secondary recycled material. Injection molding of bottle preform need to store more than 24 h before use. After heating unused bottle preform, must be reheated to store more than 48 h can use again. A bottle of billet storage time can't more than six months. 3, PET material for environmental protection, high barrier property, qualitative light, no broken properties, chemical resistance, sex is extremely strong, but make it white, pearl, colored, magnetic, widely used in hold gels water. Bottle mouth is usually 16 # #, # # 18, 22, 24 diameter, can be used with the pump head. Three, cosmetics SuPing category and process 3, injection pressure. Good PET melt flow, easy molding, usually USES the medium pressure, the pressure is 80 ~ 140 mpa, glass fiber reinforced PET injection pressure is 90 ~ 150 mpa. Should consider the determination of injection pressure, viscosity of PET, the amount and type of packing, the location and size of gate, the shape of the plastic parts, mold temperature, injection molding machine type and size, etc. 4, special distributor such as foam pump head and hand button type nozzle, is a kind of filling and gas bubble pump type hand pump head, do not need to fill gas to generate foam, only high quality foam can be produced. Equipped with a special bottle. Hand sprayer is usually used in detergents and other products. PET plastic profile: 6, mold fee: bottle blowing mold for 1500 yuan, 8000 yuan 4000 yuan, the injection mould for - 20000 yuan, the mold with stainless steel material more expensive than alloy material, but durable, die a few at a time, see the demand of production, such as production is bigger, can choose one out of four or six of the mold, the client may decide. The rheological properties of PET in the molten state, the pressure effect on the viscosity is bigger than the temperature, therefore, mainly from the pressure to change the melt flow rate. The material of plastic bottles are usually for PP, PE, K, AS, ABS, acrylic, PET, etc. PET material is environmental protection material, high barrier property, qualitative light, no broken properties, chemical resistance, sex is extremely strong, but make it white, pearl, colored, magnetic, widely used in hold gels water. Bottle mouth is usually 16 # #, # # 18, 22, 24 diameter, can be used with the pump head. In ABS, AS, ABS, AS degrees and toughness.
