Guanzhong’s Core Material System

• PET (Polyethylene Terephthalate): PET has high transparency and impact resistance, widely used for salad boxes, dessert boxes, and display-type food containers. Guanzhong uses food-grade PET, ensuring product safety while meeting recycling and environmental requirements.
• PLA (Polylactic Acid): PLA is made from corn or cassava starch and is a renewable bio-based material that can be industrially composted. Guanzhong’s PLA food containers and tableware products comply with EN13432 (EU industrial composting standard) and ASTM D6400 (US compostable standard), suitable for cold drinks, desserts, and takeaway boxes.
• PP (Polypropylene): PP is heat-resistant and steam-resistant, suitable for microwave heating and hot food packaging. Guanzhong uses food-grade PP, customizable in melt index and thickness, making containers heat-resistant, tough, and well-sealed, suitable for takeout, lunch boxes, and compartmented containers.
• Bio-based and Biodegradable Composite Materials: Through independent R&D and material modification, Guanzhong can adjust the toughness, heat resistance, and degradability of containers, ensuring compliance with different countries’ environmental policies while meeting customized needs.

Guanzhong’s Advanced Production Capabilities

• Injection Molding Capabilities: Guanzhong is equipped with 50 fully automated injection molding production lines capable of multi-cavity, high-precision forming. By precisely controlling melt temperature, injection pressure, and cooling cycles, the containers have more stable wall thickness, higher compression strength, and better sealing fit, suitable for cold dishes, hot meals, and takeaway packaging requiring high closure integrity.
• Thermoforming Lines: The company has 8 fully automated thermoforming lines mainly for deep drawing and shaping of PET, PLA, and composite sheets. The lines are equipped with automatic feeding and online cutting systems, maintaining stable transparency, stiffness, and edge flatness in high-volume production, making them core manufacturing methods for salad boxes, dessert boxes, and display-type containers.
• Bio-based Sheet and Masterbatch Production: Guanzhong owns 3 biodegradable sheet extrusion lines and 5 bio-based modified masterbatch production lines, ensuring full-chain control from material modification, sheet processing to final forming. This capability allows adjustment of material toughness, heat resistance, and degradability according to customer needs, effectively supporting professional-grade customization.
• Straw Extrusion Lines: Equipped with 5 fully automated straw extrusion lines capable of producing fine and thick PLA and bio-based straws. With temperature control and online cutting devices, the products have smooth inner walls and minimal dimensional errors, suitable for takeaway drinks, in-store use, and utensil set packaging.
• Large-scale Comprehensive Capacity: Guanzhong’s annual production capacity reaches 90,000 tons, independently handling the entire process from material modification to finished food containers.
