Product Certification

 

【Foreign】

 

DIN CERTCO certification and OK Compost certification, according to the European standard EN13432 for biodegradability and compostability, France, Belgium, Italy and others prefer OK compost, and Germany and the Netherlands prefer DIN CERTCO certification. 

Cost and cycle: If the product is made of certified materials (European and American certification), the cost is 20,000 RMB 20,000 and the cycle is about 1 month; 

If the product is made of new raw materials (without European and American

certification), the cost is about 100,000 yuan, and the cycle is more than half a year.

 Product Certification

【Domestic】

 

Third-party testing institutions such as the National Plastic Products Testing Center, Feifan Testing, and Stand Testing can test. According to the standard GB/T 19277.1, the final aerobic biodegradability of materials under controlled composting conditions is determined. Third-party testing does not issue certificates. Only provide test report, only applicable to domestic customers.

Cost and cycle: The cost is about RMB 20,000, and the test cycle is 45 days (generally can meet the standard). If the standard requirement is not met after 45 days of the test, it needs to extend the cycle (30 days). The cost is about 5,000 yuan, the longest It can be done for 180 days.


Future product direction-foamed products

 

Ø PLA foaming principle: PLA foaming is the use of physical foaming to prepare foam. The principle is to use a physical foaming agent to fully mix with PLA under a certain temperature and pressure to achieve equilibrium saturation. Then, the foaming gas and PLA The mixture of the melt undergoes thermodynamic state and changes, and saturated gas molecules escape from the melt, resulting in a foam structure with a certain pore size and density, thereby forming a PLA foam. 

Ø The expansion ratio of PLA extruded foam sheet is 10-40 times, 10-20 times can be used to produce lunch boxes and trays, and 20-40 times can be used for shock absorption packaging. 

Ø At present, the best one in China is Guangdong Bijia Material Technology Co., Ltd. Its material has high melt strength and is suitable for extrusion foaming process. Its products are widely used in disposable foamed lunch boxes, trays, and cushion packaging.

Future product direction-mulch products

 

Ø China is a large agricultural country. At present, the annual investment in mulching film is about 1.5 million tons, covering an area of ​​more than 350 million mu, and the residual film rate of farmland is about 40%. The degradation cycle of mulch film is generally 200~300 years. Long-term accumulation of mulch residues in farmland will affect crop yields.

Ø Studies have shown that when the residual film content in the soil is 58.5kg/hm2, the yield of corn will be reduced by 11% to 23%, wheat yield will be reduced by 9%-16%, soybean yield will be reduced by 5.5%-9%, and vegetable yield will be reduced by 14.6%-59.2%.

Ø National standard "GB/T35795-2017 Fully Biodegradable Agricultural Ground Cover Film".

Future product direction-fiber products

 

Ø China is a major producer of chemical fiber. In 2018, the total output of chemical fiber is expected to reach 52.6 million tons, accounting for 70% of the world's total chemical fiber output. 90% of chemical fibers are petroleum-based synthetic fibers, which are greatly restricted by petroleum resources. 

Ø The performance of PLA fiber is similar to those of general fiber, and it has the advantages of biodegradation, bacteriostasis, better UV resistance, flame retardant and barrier property, etc. Differentiated and functional PLA fiber is expected to be applied on a large scale.

Future product direction-engineering plastics

 

Ø From the perspective of long-term use,we try to modify the PLA and apply it to the fields of electronic and electrical products, office automation, communication materials and automobile interior accessories. For example, Foxconn in Japan modified PLA with polycarbonate (PC), and the PLA/PC blend obtained by injection molding products are used in computer keyboards, computer casings, Walkman casings, DVD panels and CD. 

Ø The modified PLA has good performance of impact resistance, heat resistance, rigidity and flame retardancy, etc. It has been widely used in the manufacture of computer parts, portable notebook shell, mobile phone parts, DVD player shell, CD, home appliance parts, auto parts and so on.
