Plastic bottles in the plastic packaging of cosmetics have what material request?

Plastic industry is a technical update more frequently, for new products, new technology of timely grasp is vital to the development of an enterprise. The advent of hot filling bottles is the result of such an opportunity, plastic bottles used in the cosmetics container to pack the important influence is the convenience of transport, not easy to break, better protection cosmetics. But not some plastic bottles are cable can be used in the packaging of cosmetics, countries in the plastic packaging of cosmetics have harsh request, related businesses to harsh, abide by the relevant production packing rail system. What then plastic bottles used in the cosmetics packaging material request? Whatever, plastic bottles for cosmetics packaging material divided into PP, PE, K, AS, ABS, acrylic, PET, etc. The PET material used in the cosmetics packaging plastic injection forming, tube embryos, product packaging for the bottle blowing. And radiation bottle acrylic class material, chemical resistance is poor, generally cannot be directly placed to paste, inserts for interception to equipment, fill not too full, in order to guard against and paste between the bushing and acrylic bottle, in order to transport packaging request higher scratches, seems particularly is, high permeability, super thick feelings on wall, but the price is quite expensive. Hot filling PET bottle of bottle of crystallization technology is the key, the new technology has to be able to make the bottle tolerance filling temperature 93 ℃, although from kill Jun perspective, temperature is not higher than necessary. Hot filling bottles of the future development trend are mainly concentrated in g and more bottle type. Plastic bottles of development has experienced add PEN, coated with a few process such as barrier property of coating. At present relatively feasible solution is to adopt multi-layer bottle production technology, use EVOH or nylon as barrier layer, middle but affected by factors such as cost, when the market start is not clear. PC is the main material of 5 gallons of drinking water barrels, PET manufacture it has been reported in drinking water barrels can also meet the quality requirements, but in a short period of time, the PET may still not replace the PC. BOPP bottles as a newly developed product, at present mainly concentrated in part need high temperature to kill Jun or pasteurized to kill Jun drinks, such as herbal tea, etc. The main application fields are currently focused on the big infusion products. PE containers in beverage plastic bottle blowing machine, mainly concentrated in a small number of large capacity ( Such as 5 liters) Bottled water. PET bottle used for carbonated soft drinks and bottled water has lower g space is small, the future development of mainly high speed production equipment. With the advent of the era of drink cold aseptic filling, common PET bottle again. At the same time, the use of recycled material in ordinary PET bottle production as core layer multi-layer bottle technology already quite mature, but due to the technical requirements for equipment is very high, the costs become the main factors restricting the development.
