TO, a subsidiary of Da Sai Lu GroupPATOPAS launched by S Advanced Polymers ®COCCyclic olefin copolymers have become an efficient material solution, enabling injection stretch blow molding (ISBM) process to replace extrusion blow molding (EBM) process for productionHDPE(High density polyethylene) bottle.
TOPAS ® COC is a crystal clear and highly pure plastic that is changing the world of plastic bottles and containers. When mixed with HDPE, TOPAS ® COC has solved decades old challenges, enabling packaging manufacturers to produce ISBM containers with superior performance compared to typical EBM packaging and higher recyclability. In terms of sustainability advantages, HDPE containers have reduced weight by 20-40%, reduced manufacturing waste, and improved resource utilization efficiency.
ISBM HDPE technology represents a significant advancement in the field of plastic production. By enhancing the unique characteristics of HDPE - flexibility, durability, and cost-effectiveness - and leveraging TOPAS ® With COC's unique processing capabilities, companies can finally utilize similar equipment currently used for high-speed production of billions of lightweight PET bottles to manufacture ISBM HDPE products faster and on a larger scale.
Adopting TOPAS ® COC's ISBM HDPE products have a range of characteristics that distinguish them from EBM. In terms of strength and durability, the biaxial orientation achieved in the ISBM process, combined with the high stiffness of COC, significantly improves the strength to weight ratio of the material, resulting in lightweight container products that can withstand both high impact forces and long-term use.
ISBM HDPE also has excellent resistance to various chemicals, making it an ideal choice for packaging corrosive substances or for use in harsh industrial environments. The molecular orientation achieved during the stretching process improves the barrier properties of the material, providing excellent moisture resistance, gas barrier, and resistance to other potential pollutants.
Due to TOPAS ® COC provides a higher level of heat resistance, and a notable new advantage of this technology is that ISBM HDPE containers made with specific grades of COC can withstand hot filling conditions. This is difficult or even impossible to achieve for EBM HDPE containers, thus expanding the range of materials that can safely use HDPE packaging, covering a variety of foods and beverages.
ISBM HDPE bottles have also been significantly improved in terms of aesthetics. Although HDPE itself is opaque, the ISBM process can achieve a smoother and more glossy surface than traditional EBM HDPE containers when needed. In addition, due to its efficient material utilization and high production speed, ISBM technology reduces costs and improves cost-effectiveness, making it an ideal choice for large-scale production.
The performance characteristics of ISBM HDPE can be expected to be widely used in various industries, such as in the food and beverage industry. The excellent barrier properties and chemical resistance of this material make it an ideal choice for maintaining product freshness and safety. In the fields of personal care and cosmetics, the transparency and customizable appearance design of ISBM HDPE are particularly prominent in this image conscious industry. Meanwhile, in industrial applications, the durability and chemical resistance of ISBM HDPE make it a good choice for packaging high demand industrial materials.
Colgate Palmolive is exploring the application of COC in economically efficient and high-performance HDPE packaging to meet increasingly stringent lightweight regulatory requirements. So far, the relevant achievements are encouraging, and the company plans to continue advancing the commercialization process of this technology.
