With the large infusion bottle BOPP production equipment and supporting the sterilization, filling equipment domestically, China infusion Glass bottle Packing pattern of world domination is rapidly changing, BOPP infusion bottle is showing strong growth momentum. The first half of next year, existing and under construction production capacity of BOPP bottles will exceed one billion bottles / a, BOPP transfusion bottle packaging will become a major mainstream pharmaceutical packaging. Glass bottles, soft plastic infusion bags and bottles of hard one-third of world manufacturing BOPP pattern is taking shape. Symbol Technologies Group, Hong Kong Central
developed BOPP bottles and related production technology and equipment, since the advent of the beginning caused widespread concern in the industry. Compared with PET hot-fill bottles, BOPP bottle has the following characteristics:
1. Temperature is good. The hot-fill PET bottle crystal bottle can only withstand a maximum temperature of 93 for filling, while BOPP bottles can easily withstand temperatures above 95 , so hot filling process a breeze;
2. Low cost. PP PET resin than the average around 200 U.S. dollars per ton cheaper, and market stability. Together with other factors, BOPP bottles lower than the average cost of PET bottles more than 20%.
3. Production process is simple. As the PP resin itself does not absorb moisture, so as PET resin before processing without using specialized equipment to do the same drying treatment, and need not deal with the heat setting and crystal bottle, easy to control the entire production process. And a set of equipment can produce common BOPP bottles, can also produce hot filling bottles, the production rate will not fall.
4. Equipment, a small investment. Since no drying and heat setting equipment, BOPP production equipment than the hot-fill PET equipment is cheap;
5. High capacity utilization. As the hot filling PET bottles easily absorb moisture decreased crystallinity to decrease heat resistance, so shelf life is usually not more than 14 days.
Bottled drinks constitute the largest cost factor is the packaging, beverage packaging accounted for direct costs generally constitute more than 60%. Peak, a Tea Bottles can be sold for more than one money. Therefore, the choice quality and cheap bottles, not only for the drinks company’s survival, but also directly affect the price of drinks and the vital interests of consumers.
Vast majority of tea drinks currently on the market using a PET Plastic bottles . PET mineral water and general costumes, different tea drinks hot filling treatment needs require a bottle of good heat resistance, high strength. Therefore, the tea beverage packaging is heat setting treatment after hot-fill PET bottles. By increasing the crystallinity of PET resin to increase strength and temperature of the bottle.
PET hot-fill bottles of transparency and barrier properties are better, more mature technology. Less than more costly and more complicated production process, PET raw materials and bottles are easy to absorb moisture, the storage of empty shelf life is short, on the production and full utilization of equipment, negative, and one-time investment in large equipment.
