1、Fast growing market of plastics packaging
With the high increase in China’s domestic retail and export market, the corresponding packaging industry is rising sharply. During this course, a variety of new materials, new equipments, and high-end technologies are emerging.
The plastics packaging industry covers a wide range, including household appliances, daily necessities, food, automotive, medical treatment, cosmetics, electronics, toys, etc. With the continuous improvement of living standards, plastics packaging is developing towards diversification, specialization, intelligence, personalization, energy conservation and environmental protection, and other multi-functional directions
2、PET raw materials and thin-walled injection molding technology
PET is a non-toxic, odorless raw material with good health and safety characteristics to be directly used in food packaging. It has low gas and water vapor permeability and excellent gas resistance, water, oil, and odor resistance. Therefore, it is widely used in the traditional bottle preform industry. With the stringent environmental protection, PET is used widely in the thin-walled packaging and injection molding industry with a relatively complete recycling system.
Most food packaging prefers thin-walled injection molding technology. The products have attracted attention due to the advantages of low parts weight, small scale, low material consumption, and short molding cycle time. Generally speaking, a product with a wall thickness less than 1mm is called a thin-walled product. It is further understood that the definition of a thin wall is related to the flow/wall thickness ratio, the viscosity of plastic, and the heat transfer coefficient.
3、Haitian PET thin-walled packaging solutions
To solve the issues of thin-walled PET such as poor fluidity, molding difficulties, easy crystallization, and white spots, Haitian International and Haitian Smart Solutions provide customers with a complete set of solutions to support the packaging industry.
- Faster injection speed, greatly improves the effective filling capacity on the premise of overcoming the resistance along the way. According to the wall thickness characteristics of the product, there are a variety of injection components to choose from.
- The highly rigid mechanical structure and excellent centering capability effectively avoid the industry pain point that the actual product wall thickness is greater than the designed wall thickness.
- The plasticizing chrome plating screw for PET can effectively increase the plasticizing effect and make the process easier.
- Quick response systems greatly improve the injection acceleration ability and filling capacity.
- Multi-stage injection, precise pressure control, and cooling system avoid white spots at the mold gate.
- The 2 + 2 mold design reduces the mold models and investment cost to meet the diversified product demands of processors.
- Haitians stable, efficient and accurate in-mold labeling system, enhances the added value for products and fully embodies the “value economy”.
