PET bottle market advantage and disadvantage analysis
PET bottles due to their light weight, easy to transport and carry, beer, beverage manufacturers and consumers of all ages. But because of the gas permeability of PET bottles (oxygen into the bottle, carbon dioxide escaping outwards), use it to package beer life is affected. In the next period of time, need to be further used batch test method, gradual improvement of PET bottle of beer filling equipment and the applicability of the shelf life of beer.
(A) advantages of PET bottles
1 is better than glass beer bottles, PET bottles in security;
2, PET bottle is light, easy to transport over long distances, for beer companies can save on shipping costs;
3, portability is superior to glass bottles and cans of beer in PET bottles, novelty, difference can adapt to young people;
4, Brown, oxygen barrier PET bottles filling beer or in the sterilization unit premium beer, premium beer can improve the appearance of the image;
5, PET bottles type and capacity selection of more flexible, can produce a different bottle sizes, different volumes of products, rich product varieties.
(B) the defects of PET bottles
1, PET bottles for beer filling equipment adaptability was poor. As PET bottle cannot with wash bottle machine cleaning, only with high pressure no bacteria water flush, bottle within of no bacteria State cannot guarantee (especially on after long-term store of bottle); not heat of PET bottle cannot through BA's sterilization machine, on packaging workshop of no bacteria State requirements high; PET bottle of posted standard way and existing glass posted standard way has larger differences, needed transformation posted standard machine.
2, PET bottles on the shelf life of beer: the carbon dioxide loss 10%-15% after filling, beer beer of oxygen into the aging process. PET bottles need to improve protection against ultraviolet rays, prevent sunlight smelly in the beer.
3, no matter what material will inevitably be a small amount of organic monomers of organic synthesis, when the inner wall of bottles and beer in contact for a long time, dissolution will have trace amounts of organic matter.
4, the strength of the PET bottle. Due to the strength of the PET bottle than a glass cannot be ruled out using two vacuum air inside the bottle, not directly with Crown caps Cap machine
