Europe’s Leading Biodegradable Garbage Bag Manufacturers

Guanzhong’s Professional Technology and Material Advantages

• High-Performance Eco-Friendly Materials: Guanzhong uses PLA (polylactic acid) and PBAT (polybutylene adipate terephthalate) composite materials. PLA provides natural biodegradability, while PBAT enhances toughness and tear resistance, ensuring the garbage bags remain stable under heavy loads, wet waste, or sharp items. Materials are strictly selected, non-toxic, odorless, and meet food contact standards, providing B2B clients with safe and reliable products.
• Advanced Film Blowing Technology: The company operates 50 biodegradable film blowing production lines, precisely controlling film temperature, stretching ratio, and thickness to ensure each batch of garbage bags has uniform thickness and stable mechanical performance. This process improves tear resistance and reduces production waste, reflecting the company’s commitment to green manufacturing.
• Precision Bag Making and Heat Sealing: 25 bag-making lines combined with automatic heat sealing ensure uniform seals, high strength, and excellent leak resistance. Whether vest-style bags or compartment bags, they maintain tensile and puncture resistance, meeting the application needs of various B2B clients.
• Diversified Injection Molding and Forming Capabilities: Guanzhong is equipped with 50 fully automated injection molding lines capable of producing various bag types, reinforced structures, and functional designs, such as double-layer reinforcement and puncture-resistant textures. Accurate molding ensures consistent bag shapes and stable quality, reducing breakage risk during use.
• Practical Design and User ExperienceEach garbage bag undergoes mechanical testing and real-world scenario simulations. Double-layer reinforcement, leak-proof, and puncture-resistant designs enhance safety, reduce damage during use, and facilitate handling, offering efficient and reliable waste management solutions for restaurants, retailers, and industrial clients.
