Technical update of the cosmetic packaging material hose industry

The cosmetics packaging material hose industry is an industry with frequent technological updates. For new products, timely mastery of new technologies is vital to the development of an enterprise. The emergence of hot-filled cosmetic packaging material hoses is also the result of such an opportunity. Here are some introductions and precautions about it.

The bottleneck crystallization technology of hot-filled PET bottles is the key. At present, the new technology can make the bottle tolerate the filling temperature of 93℃, although from the perspective of killing feces, higher temperature may not be more than necessary . The future development trend of hot-filled bottles is mainly focused on reducing the weight and developing more bottle types.

The development of cosmetic packaging material hoses has gone through several processes such as adding PEN and applying barrier coatings. At present, a more feasible solution is to use multilayer bottle production technology with EVOH or nylon as the barrier layer. However, due to cost and other factors, 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 period of time, PET still has no possibility of replacing PC.

As a newly developed product, BOPP bottles are currently mainly concentrated on some beverages that require high-temperature or pasteurization, such as herbal tea. Its main application areas are currently concentrated on large infusion products. PE containers are not widely used in beverage plastic blow molding machines, mainly in a small amount of large-capacity (such as 5 liters) bottled water.

The space for reducing the weight of PET bottles used for carbonated beverages and bottled water is already very small. The future development is mainly to increase the speed of production equipment. With the advent of the era of cold aseptic beverage filling, ordinary PET bottles are making a comeback. At the same time, the multi-layer bottle technology that uses recycled materials as the core layer in the production of ordinary PET bottles has been quite mature, but due to the high requirements of this technology on equipment, cost has become the main factor restricting development.
