Guanzhong’s Material and Technical Advantages

Guanzhong’s bag products use PLA+PBAT bio-based modified composite materials as the core, combining biodegradability and mechanical performance advantages. PLA (polylactic acid) is derived from renewable plant starch, fermented to produce lactic acid and then polymerized, representing a typical environmentally friendly material. PBAT provides excellent flexibility and tear resistance, preventing film breakage during stretching while maintaining toughness and extensibility.

Regarding compostability, Guanzhong’s products have obtained multiple domestic and international certifications:

• China GB/T 20197, GB/T 19277.1, GB/T 4806.7 biodegradability and food contact tests
• ASTM D6866, ASTM D6400 international standards for bio-based content and biodegradability
• European DIN EN 13432 industrial composting certification
• U.S. BPI compostability certification

These certifications not only ensure the environmental performance of the bags but also comply with stringent regulations in the European and North American markets, providing highly credible product assurance for customers.

Technically, Guanzhong is equipped with industry-leading facilities and processes:

• 50 fully automated film blowing lines with 25 bag making lines, monthly output up to 1,500 tons
• 3 biodegradable sheet extrusion lines and 5 bio-based masterbatch production lines, monthly output 2,000 tons
• 50 fully automated injection molding lines, monthly output about 2,000 tons
• 8 blister forming lines, monthly output about 800 tons

These advanced facilities allow Guanzhong to produce bags in various specifications, thicknesses, and applications while ensuring excellent tensile resistance, tear resistance, and double-thick performance.

Additionally, Guanzhong continuously innovates technology, optimizing material ratios and modification processes to improve heat resistance, cold resistance, and durability, ensuring stable performance in different usage scenarios. This technical advantage reflects the company’s deep strength in the research and development of bio-based environmentally friendly materials.
