Material Insights: PLA+PBAT Modified Biodegradable Bags

Guanzhong’s custom biodegradable bags mainly use PLA+PBAT modified biodegradable materials, balancing environmental performance and user experience. Its advantages include:

• Natural Bio-Based Materials: PLA (polylactic acid) is derived from corn starch or sugarcane; PBAT (polybutylene adipate terephthalate) is a flexible biodegradable material that enhances bag toughness. The materials are natural, safe, non-toxic, odorless, and suitable for direct food contact.
• Excellent Biodegradability: Under industrial composting or soil conditions, PLA+PBAT bags fully degrade within 90–180 days, producing only water and carbon dioxide, harmless to the environment; compliant with ASTM D6400, DIN EN 13432, BPI, and other international certification standards.
• High Strength and Durability: PBAT provides flexibility and tear resistance, PLA provides rigidity and transparency; double-sided thickening design ensures bags are stretch and tear-resistant, balancing lightness and durability; suitable for retail, logistics, and heavy load transport scenarios.
• Flexible Applications: Suitable for shopping bags, trash bags, pet waste bags, and food packaging; PLA offers transparent or semi-transparent effect, PBAT enhances durability, fitting various corporate green packaging needs.
