Xinjiang PET plastic packaging bottle high-quality manufacturers, MGG companies worth choosing. PET plastic packaging bottles provided by MGG, transparent plastic packaging bottles are excellent, enabling customers to use lower prices to use better products. Pet blow molding bottle It can be divided into two categories, one type is a bottle such as a bottle that is filled with carbonated drinks; the other is a non-pressure bottle, such as filling water, tea, oil, etc. The tea beverage bottle is a modified PET bottle or PET and a thermoplastic polyarylate that is blended with polyvyl methacodate (PEN), which is a heat bottle, which can heat 80 ° C; the water bottle belongs to the water bottle Cold bottle, no need for heat resistance. The heat bottle is similar to the cold bottle on the molding process.
The author mainly discusses the pressure beverage bottle forming process in the cold bottle. With the continuous improvement of technology and production, PET blowing machine has become higher and higher, and production efficiency is getting higher and higher. The production capacity of equipment is continuously improved, and thousands of bottles produced from the previous hour will now produce tens of thousands of bottles every hour.
Operation is also developed by the past manual button to currently control, which greatly reduces the difficulty of process operation, increasing the stability of the process. At present, the manufacturer of injection and blowing equipment mainly has Sidel, Germany, etc. in France. Although the manufacturer is different, but its equipment principles are similar, generally include the supply system, heating system, blowing system, control system and auxiliary machine five parts of PET plastic is an abbreviation, referred to as PET or PETP.
The meaning of polyethylene terephthalic plastic mainly includes polyethylene terephthalate PET and polyethylene terephthalate PBT. Polyethylene terephthalate is commonly known as polyester resin, commonly known as polyester resin. It is a polycondensate of terephthalic acid with ethylene glycol, which is collectively referred to as a thermoplastic polyester together with PBT, or a saturated polyester.
Polyester is a general term represented by PET represented by PET, including PET, PBT, PEN, PCT and its copolymers. PET is the earliest, large output, and the most widely used polyester products. PET recycled plastic can be used on the food packaging, which can achieve unlimited regeneration cycles.
This is the environmental protection technology technology that my country's tentacles. Due to the raw materials of plastic packaging from oil, in order to save resources, many developed countries have developed recycling technologies for plastic packaging, and the regeneration PET plastic slice has been used as food packaging materials in 1991.
