Analysis of 25 Core Advantages of Corn Starch Meal Bag Packaging
High-Performance Degradable Solutions for Modern Food Service Needs
Corn starch packaging converts agricultural renewable resources into high-performance, fully degradable food packaging solutions. It offers excellent rim rigidity, heat resistance, and complete product certification for hot food, oily food, and takeout scenarios.
Key Advantages of Corn Starch Packaging
Corn starch packaging represents a revolutionary approach to sustainable food packaging, combining renewable materials with high-performance characteristics. With temperature ranges from -20°C to 120°C, industrial composting certification, and PFAS-free options, it provides comprehensive solutions for modern food service requirements.
1. Utilization of Renewable Raw Materials
Annual renewable corn resources are adopted to replace petroleum-based raw materials. According to the data from the Ministry of Agriculture and Rural Affairs of China in 2024, the annual corn output in China reached 272 million tons, ensuring a stable and reliable supply of raw materials.
2. Industrial Composting Certification
Certified by EN13432/ASTM D6400, with a biodegradation rate of ≥90% within 180 days under industrial composting conditions. Each SKU is provided with an independent certification certificate.
3. Reduced Reliance on Fossil Energy
Replace petroleum-based plastics such as PS/PP/PET, helping brand owners comply with the requirements of the "Action Plan for Plastic Pollution Control during the 14th Five-Year Plan" issued by the National Development and Reform Commission.
4. Wide Temperature Range Applicability
The operating temperature range is from -20°C to 120°C, suitable for all scenarios from frozen storage to microwave heating. Experimental data shows no leakage after 30 minutes in 100°C hot oil.
5. Excellent Structural Rigidity
The cup mouth rigidity index reaches 85N, ensuring it does not collapse when held with one hand. It is particularly suitable for scenarios such as buffets and school cafeterias where meals are consumed on the move.
6. Flexible Design Options
Supports injection molding of various complex structures, including multi-compartment lunch boxes, deep bowls, and stackable designs, meeting the needs of different dining scenarios.
7. PFAS Zero-Addition Commitment
Provide a written statement of "No Intentional Addition of PFAS", along with a third-party test report (detection limit ≤ 100 ppm).
8. Microwave Compatibility Verified
Passed the microwave compatibility test in accordance with GB 4806.7-2023, remaining undistorted after being heated at 800W for 3 minutes.
9. Full-scenario Service Coverage
Suitable for all scenarios including dine-in, takeout, and delivery. With a sealed lid, it can maintain heat and freshness for 60 minutes.
10. Cost Optimization through Scale
Achieve cost control in large-scale production by standardizing the size of the cover and optimizing the product weight (reducing by 10-15%).
11. Clear Environmental Protection Labels
Provide clear compostable labels and disposal instructions to help build the brand's environmental protection image.
12. Policy Compliance Advantage
Complies with the plastic ban policies of major global markets and provides a complete package of compliance certification documents.
Additional Advantages (13-25)
Other significant benefits include superior oil resistance, excellent moisture barrier properties, customizable branding options, reduced carbon footprint, food safety compliance, enhanced customer perception, operational efficiency improvements, waste reduction benefits, supply chain stability, technical support services, competitive pricing, rapid delivery capabilities, and comprehensive after-sales support.
