The plastic bottle industry is an industry with frequent technological updates. For new products, timely mastery of new technologies is crucial to the development of an enterprise. The emergence of hot-filled plastic bottles is also the result of such an opportunity. The important role of plastic bottles in cosmetic container packaging is that they are easy to transport, not easy to break, and better shelter cosmetics. But are all the plastic bottles available for packaging cosmetics? Guojia has strict requirements on cosmetic plastic packaging, and relevant companies must strictly abide by the relevant production and packaging regulations. Then what are the material requirements for plastic bottles used in cosmetic packaging?

Generally speaking, the materials used for cosmetic packaging of plastic bottles are divided into PP, PE, K material, AS, ABS, acrylic, PET, etc. Among them, the PET material is used for the molding of cosmetic packaging plastic bottles, the tube embryo is injection molding, and the product packaging is blow molding. Acrylic-based radioactive bottles have poor chemical resistance and generally cannot be directly placed in a paste form. The liner to be equipped is intercepted, and the filling is not easy to be too full to prevent sticking between the liner and the acrylic bottle, so that the transportation and packaging requirements are higher. The scratches look particularly sharp, with high magnetic permeability and super thick feeling on the wall, but the price is quite expensive.

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

The development of plastic bottles 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 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 period of time, PET still has no possibility of replacing PC.

As a newly developed product, BOPP bottles are currently mainly focused 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 concentrated 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 filling of beverages, 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 for equipment, the cost has become the main factor restricting development.
