PET bottle technology than about 30 years ago developed by the DuPont system of law after the biaxial stretch. Began to grow rapidly. In use in Europe from 23 million tonnes in 1987 to 550,000 tonnes in 1992 and 900,000 in 2000 tonnes. The amount of the world's 2.4 million tons from 1993 to 2000, five million tons annually at an average rate of 10% growth. biaxially-oriented PET bottles with the following characteristics

1, good transparency and gloss performance, with modern.
2, the weight is much lighter than glass bottles or direct blow PVC bottles.
3, poor ventilation, good for carbon dioxide, oxygen and other gas barrier properties.
4, excellent food hygiene
5, resistant to almost all organic solvents.

Therefore, PET is widely used in the mineral water bottles, soft drinks, soft drinks, and cooking oil bottles, cosmetics, condiments, cleaning agents bottle. And are continuing to grow every year.

Recovery of PET material is substantial growth every year. Feedstock recycling after use is very wide and can then made a bottle, carpet, strapping, fiber fillers, etc. for environmental protection, it is ideal for plastic containers.
Second, the characteristics of PET material(Melt phase) a molten polymer early PET manufacturing process, an average of about 80 to 100 fat cells linked together. PET this financial state escorted out and cut into pellets, its IV (intrinsic viscosity) value of about 0.6 can be pumped directly into the wire, it becomes a polyester yarn for textile use of solid state polymerization (solid statepolymerization), the initial polymerization of PET is reheated to 200∘C grains above, but below the melting point, filled with nitrogen or vacuum cycle to remove ethylene glycol, to produce a polymerization reaction in the solid state polymerization of PET can process The increase in molecular weight. time and temperature level of the polymerization of the relevant molecular weight, the longer the higher molecular weight, high temperature polymerization time can be shortened. Usually blowing with IV values ​​between about 0.72 to 0.80, higher heat filling bottle , is about 0.83.

PET is generally used in the container material to note the following features; 1, molecular weight (IV) 2, the amount of diethylene glycol (diethylene glycol, DEG) 3, acetaldehyde content (acetaldehye) 4, a carboxyl group (carboxyl end groups) 5, crystallization degree, 6, melting point, 7, the glass transition point, 8, the percentage of total polymer (copolymer content)
