PLA+PBAT Material Analysis: Core Technology and Performance Advantages of Compostable Bags

Guanzhong’s biodegradable bags mainly use PLA (Polylactic Acid) + PBAT (Polybutylene Adipate Terephthalate) modified materials, balancing environmental friendliness and mechanical performance.

• PLA: derived from renewable resources like corn starch, non-toxic, odorless, safe, and fully degradable in soil or industrial composting conditions
• PBAT: provides flexibility and tear resistance, making the bags strong and durable
• Modification Technology: Guanzhong can adjust thickness, tensile strength, and degradation cycle according to customer needs for custom biodegradable bags

Material Advantages

• High environmental friendliness: completely absorbed and degraded in soil
• Excellent mechanical performance: double-thick design, stretch and tear resistant
• Customizable: size, thickness, color, pattern, and structure are flexible
• Lifecycle design: the whole process from raw materials to finished products follows green environmental concepts

International Standards and Certifications

• China: GB/T 20197, GB/T 19277.1, GB/T 4806.7
• International: ASTM D6866, ASTM D6400, DIN EN 13432, FDA food contact test
• Industrial compost and biobased certifications: International Industrial Compost Certification, DIN Industrial Compost Certification, DIN Biobased Product Certification, US BPI Degradation Certification

Through optimization and modification of PLA+PBAT materials, Guanzhong can produce high-quality, stable-performance custom biodegradable bags, meeting the practical needs of wholesale customers in different scenarios.
