Summer has arrived, how fun is to a bottle of cold beer ah! Needless to say, I am sure you know that the traditional beer bottle packaging materials for the first generation and second generation of glass bottles aluminum cans, as people within the industry, when we can drink beer in plastic bottles ?
As a beer bottle packaging materials, the performance required to meet the following requirements:

Carbon dioxide overflow rate is lower, in order to maintain the taste. General provisions carbon dioxide 120 days overflow rate of less than 5%.
Oxygen and light beer is extremely sensitive, requiring oxygen penetration rate is low, in order to prevent deterioration, in order to increase shelf life. General provisions penetration rate of less than 120 days 10-6g; specific provisions of different countries present, generally 120 days, but 110 days for the United States, the European requirements for up to 180 days.
Temperature resistant material to withstand a beer bottle pasteurization temperature pasteurization temperature is generally 75 ~ 80 , the processing time is 15 minutes. In addition, it can withstand high temperature heat-resisting temperature even after the wash cycle, generally 75 ~ 80  under with lye cleaning.
Have sufficient rigidity to withstand the canning operation and laying laminate.
Absolutely non-toxic, can not contain harmful substances.
Easy to scratch hard surface to ensure that can be recycled.
Transparency, and transparency is generally greater than 80% or more, to ensure that the packaging is clearly visible, in order to increase consumer desire to buy.

Waste bottles can be recycled, so as not to be discarded in nature to pollute the environment.
Compared with the traditional beer packaging materials, plastic beer bottles have the following characteristics:
Light quality - easy to carry, save transportation costs; the relative density of only glass bottles of 12 or so, and the thickness of the plastic beer bottle beer bottle glass thickness of only 12 or so, so its total weight is only about 14 bottles .
Unbreakable - plastic beer bottles with high impact properties, or collide with each other after the fall from the car filled with beer will not be broken, and in the cold winter will be, too, can greatly reduce the beer during storage and transport losses.
Easy to Explode - plastic bottles with good pressure resistance, under the pressure of its bottled beer explosion zero chance, can effectively protect the safety of human life. Traditional glass of beer there are security risks, which not only threaten the safety of consumers, but also caused enormous psychological burden and damages to the beer producer. Plastic beer bottles to ensure safety of personnel, health beer bottle packaging materials.
Switch freely - convenient intermittent drinking.

Currently the main material of plastic beer bottles
All aspects of pure PET material is pure PET are good, and the low price of pure PET, but in the heat resistance, strength, barrier properties, etc. can not fully meet the requirements of a beer bottle, scratch resistance is not good.
Pure PEN material compared with PET, PEN in barrier properties and heat resistance can fully meet both beer packaging performance requirements, its oxygen barrier six times higher than that of PET, for CO2 barrier is 4.5 times higher than that of PET, temperature can be increased to 118 , suitable for high-temperature sterilization. PEN is by far the most suitable heat canned beer bottle packaging materials, but the price is higher than PET PEN more than five times higher than the current market, although a small amount of pure PEN beer bottle applications, it is difficult to popularize.

§ PET blends modified material is incorporated into the blend of PET barrier higher than other barrier in PET resin. Blended resin commonly used varieties of PEN, MXD6, EVOH, LCP, among PEN barrier six times higher than PET, EVOH barrier 100 times higher than the PET, MXD6 barrier 20 times higher than that of PET, LCP barrier high than PET 200 times.

We can not drink beer in plastic bottles, what is the reason?

Currently plastic beer bottle technology is mature, large-scale promotion is not a technical issue. In other countries, North America, Budweiser (Budweiser), Eagle (SoaringEagle) and other well-known beer brands have begun to use PET bottles. Mainly in the domestic price and recyclable issues. Bottle price is about 0.5 yuan, and can be recycled. The high price of plastic beer bottles, wherein the composite, blending, coating PET bottle price in more than $ 1, and can not be recycled. Higher prices PEN beer bottle, reaching about 1.5 to 2 yuan, the reasons for the PEN material to be imported, five times the price of raw materials of PET.
