Plastic Bottle Cap mould Industry Technology
2019-12-20
Update The plastic bottle cap mould industry is a relatively frequent technology update industry. For new products, the timely grasp of new cap mould technologies is vital to the development of an enterprise. The emergence of hot-filled plastic bottles cap mould is also the result of such an opportunity. Here are some introductions and precautions about it.
Hot-fill PET bottle crystallization technology is the key. At present, the latest technology can make the bottle tolerate the filling temperature of 93 ℃, although higher temperature may not be necessary from the perspective of sterilization. The future development trend of hot-filled bottles is mainly focused on reducing the weight and developing more bottle shapes.
The development of plastic bottles has gone through several processes such as adding PEN and applying barrier coatings. At present, the more feasible solution is to use multi-layer bottle production technology, with EVOH or nylon as the barrier layer. However, due to factors such as cost, it is not clear when this market will start. PC is currently the main material for making 5 gallon drinking buckets. It has been reported that drinking buckets made of PET can also meet the quality requirements, but in a short time, PET still has no possibility to replace PC.
As a newly developed product, BOPP bottles are mainly concentrated on some beverages that require high-temperature sterilization or pasteurization, such as herbal tea. Its main application area is currently focused on large infusion products. PE containers are not widely used in beverage plastic bottle blowing machines, mainly concentrated on a small amount of large-capacity (such as 5 liters) bottled water.
PET bottles for carbonated beverages and bottled water have little space to reduce their weight. The future development is mainly the high-speed production equipment. With the advent of cold and aseptic filling of beverages, ordinary PET bottles are likely to make a comeback. At the same time, the technology of multi-layer bottles using recycled materials as the core layer in the production of ordinary PET bottles is quite mature, but because of the high equipment requirements of this technology, cost has become a major factor restricting development.
