Guanzhong Core Materials: PLA and CPLA

Guanzhong focuses on PLA and CPLA two major bio-based material systems, ensuring consistent performance and food safety compliance of biodegradable food containers under different temperature and application scenarios.

1. PLA (Polylactic Acid): Eco-Friendly Cold Food Packaging Core Material

PLA is a bio-based material derived from plant starch and is one of the most widely used biodegradable plastics globally. In Guanzhong’s food container system, PLA is mainly used for cold and room-temperature food packaging, offering excellent transparency and molding stability.

• Material source: fermented from corn, cassava, and other plant starches, renewable in nature
• Appearance: high transparency, similar to traditional plastic, suitable for display packaging
• Structural properties: good rigidity and stable molding, suitable for standardized production
• Applications: salad boxes, fruit boxes, cold drink cups, and refrigerated food packaging
• Usage limitation: temperature resistance approx. 0°C–50°C, not suitable for high-temperature or microwave use

2. CPLA (Crystallized Polylactic Acid): High-Temperature Food Packaging Solution

CPLA is an upgraded material formed by crystallizing PLA through modification processes, significantly improving heat resistance for hot food packaging applications.

• Heat resistance: can withstand approx. 85°C–100°C
• Structural stability: strong anti-deformation performance, suitable for hot food delivery scenarios
• Material properties: retains bio-based origin and industrial compostability
• Applications: hot food delivery boxes, coffee cup lids, beverage lids, and hot meal packaging
• Technical advantage: higher strength and thermal stability compared to PLA, better suited for modern food delivery systems

Production Process and Quality Control System

Guanzhong has established a complete industrial system covering raw material processing to final product delivery, ensuring stability and consistency of biodegradable food containers in the global market through standardized production processes and strict quality control mechanisms.

1. Production Process System (Industrial Manufacturing from Raw Materials to Finished Products)

Guanzhong adopts a highly automated and standardized production model, converting PLA and CPLA bio-based materials into high-quality food container products through fully controlled production processes.

• Raw material inspection: testing melt index, purity, and food-grade safety of PLA and CPLA materials to ensure compliance with production standards
• Molding production: using fully automated injection molding and thermoforming equipment, injection molding for structural parts and thermoforming for lightweight and transparent packaging products
• Surface treatment: food-grade oil-resistant coating and structural optimization including leak-proof design and edge reinforcement
• Finished packaging: standardized moisture-proof and pressure-resistant packaging with batch coding traceability system

2. Quality Control System (Full Process Inspection and Standardized Management)

Guanzhong has established a full-process quality management system to ensure each batch meets international food contact safety and biodegradable material standards.

• Raw material control: all PLA and CPLA materials must pass food-grade safety testing with no harmful residues
• Process monitoring: real-time monitoring of temperature, pressure, and molding time to ensure product consistency and batch stability
• Finished product testing: high-temperature resistance, compression, sealing, and simulated compost degradation tests
• Traceability system: batch coding management for full lifecycle traceability and accountability
