CPLA degradable products are more environmentally safe

With the issuance of the "Opinions on Further Strengthening the Treatment of Plastic Pollution" by the National Development and Reform Commission and the Ministry of Ecology and Environment, the use of non degradable disposable plastic straws in the catering industry is prohibited nationwide, and the environmental pollution of plastic waste in China has been effectively curbed. In response to policies and environmental protection, the market has begun to focus on CPLA degradable products.

CPLA refers to PLA after crystallization, and the heat resistance temperature of CPLA is significantly higher than that of PLA. As a leading biodegradable catering enterprise, Changzhou Bio Hotel Supplies Co., Ltd.   has improved the performance and production efficiency of its CPLA cup covers, knives, forks, spoons, straws, and other products through modifying PLA materials, improving production equipment, optimizing molds, and production processes.

(1) CPLA Cup Lid Forming Technology.

Currently, the production efficiency of CPLA cup caps on the market is about 10 molds/minute, and the yield is about 90%. Bio Hotel Supplies CPLA cup lid molding technology improves the crystallization speed and heat resistance of the material by improving the PLA particle material modification formula; In the molding stage, this technology improves the crystallization process, improves the temperature control accuracy of the molding machine, optimizes mold temperature control, and improves product stability and production efficiency. Using this technology to produce CPLA cup caps can reach over 18 molds per minute, and the yield can be increased to over 98%.

(2) CPLA knife fork spoon molding technology.

CPLA knives, forks, and spoons on the market generally have sharp edges, burrs, brittleness, deformation, poor heat resistance, and low production efficiency.

Bio Hotel Supplies CPLA knife, fork, and spoon molding technology improves the performance of PLA modified materials in melt fluidity, crystallization rate, and other aspects by modifying materials, developing special molds, and optimizing injection molding production lines; The product has a high yield, smooth and burr-free, and can be used normally at a high temperature of 100 ℃ without deformation; In addition, due to the improvement in crystallization rate, the product molding efficiency has been significantly improved.

(3) CPLA pipette molding technology.

PLA straws are similar to traditional PP straws at room temperature, but due to the nature of PLA itself, there is a significant softening phenomenon at about 50 ℃, while the requirements for high-temperature resistance of conventional hot drinks to straws are usually around 80 ℃. At the same time, most existing CPLA straw products on the market have problems such as short shelf life, easy aging, hydrolysis, and food safety risks.

To address the above pain points, Bio Hotel Supplies has modified the materials, optimized the formulation design, and improved the process flow to ensure that the produced straw has uniform wall thickness, stable pipe diameter, better heat resistance, roundness, and no burrs. The consumer experience is better. The product still maintains high strength at a water temperature of 95 ℃, can be stirred without bending or deformation, and the shelf life can reach more than 12 months.

While upgrading product performance, Bio Hotel Supplies also focuses on providing customers with a better product experience. In the future, Bio Hotel Supplies will continue to expand the depth of its products and services and continue to meet new market demands by investing in and constructing "30000t/a PLA compostable green biological products project", "intelligent upgrading and transformation project", and "R&D technology center project".
