which can be within a few hours to make beer can not drink.PET bottle of another problem is unable to bear the beer for pasteurization when the higher temperature 78 ℃, bear 15 min.) According to the United States BP Amoco company said, to produce qualified beer bottles, should have a higher resistance to gas permeability performance, and can withstand pasteurization temperature. A few years ago, a Polyethylene naphthalate (PEN), which is similar to PET chemical structure, is considered to have a good prospect in the field of beer bottle manufacture.PEN melting point is 263 ℃, close to PET, glass transition temperature is above 113 ℃ , More than 40 ℃ above PET, long-term use temperature above 155 ℃, product size and stability, heat shrinkage is less than PET.PEN gas barrier is good, the O2 barrier than PET 4 times, the barrier to CO2 5 times higher than the water barrier 3.5 times .PEN transparent in the visible light range, and can be blocked beer sensitive less than 380nm UV. Packed in pure PEN bottles of beer, storage life can be as long as 6 months. However, PEN expensive, has not yet reached mass production.Therefore, the current PEN plastic beer bottle market positioning is more expensive high-end beer. Plastic beer bottles in recent years, the international competition research and development of new packaging materials. Compared with the glass beer bottle, its advantages: than the glass light, can reduce the storage and transportation costs; good security, easy to break, easy to explode; its shortcomings: the beer is easy to oxidize deterioration, very sensitive to light,
And usually need to ensure that 120
Days of storage, therefore, the application of plastic in the beer bottle market than in the mineral water bottle and soft drinks market application is much more difficult. However, as long as the use of advanced technology to develop the appropriate plastic varieties, these shortcomings can be completely overcome.

The key to the selection of plastic beer bottles is storage life and cost. Factors related to the former include the barrier properties of the material to the gas (to prevent oxygen ingress and carbon dioxide exudation), the UV resistance of the material, and the like, including raw material prices, raw material availability, and recyclability. At present, foreign plastic beer bottles are the following: ● polyethylene terephthalate (PET): the current soft drinks used PET is PET. But used as a beer bottle, because PET gas barrier is poor, easy to make beer take the gas
