Glass packaging, due to its good barrier properties, is predominantly used for high-end sauces and alcoholic beverages, but its development is constrained by issues such as heavy weight and high energy consumption.

(II) Application characteristics of mainstream materials

Traditional plastic packaging: Compliant materials such as PE, PP, and PET have stable molecules and are suitable for different food scenarios, but the use of non-compliant PVC, recycled materials, and migration of additives still pose safety hazards.

Bio-based and degradable materials: PLA, PBAT, PHA, etc. have become research and development hotspots. China has set a target of 30% substitution rate for degradable materials by 2025, but PBAT faces issues of overcapacity (operating rate below 60%) and high costs.

Composite and functional materials: Multi-layer composite films (such as BOPP/PE, PET/AL/PE) enhance barrier properties through structural optimization. Modified Atmosphere Packaging (MAP) can extend the shelf life of refrigerated foods by 30%-50%, and is rapidly gaining popularity in the cooked food and fresh food sectors.

Printing and production process: Water-based ink and solvent-free laminating technology are gradually replacing traditional solvent-based processes, reducing the risk of residues. However, due to cost pressures, some small and medium-sized enterprises still exhibit non-compliant practices.

(III) Current status of policies and supervision

73 countries globally have implemented mandatory recyclable packaging regulations. China's GB 4806 series standards enhance the safety requirements for food contact materials, while the EU's Green Deal aims to increase the use of renewable materials to 42%. Carbon footprint accounting has become a new threshold for import and export trade, with enterprises incurring additional compliance costs accounting for approximately 2.3% of revenue. However, issues such as an imperfect recycling system and the influx of non-food-grade recycled materials into the food packaging sector still need to be addressed.

II. Core challenges faced by industry development

Balancing environmental protection and cost: The cost of biodegradable materials is approximately 18% higher than that of traditional plastics, posing financial pressure on enterprises undergoing transformation. Materials such as PBAT are constrained in their large-scale application due to price fluctuations in upstream BDO and insufficient capacity utilization.

Technical and standard bottlenecks: High-end biobased materials rely on imports, and domestic modification technology is insufficient; the degradation conditions and testing standards for degradable materials are not unified, affecting market trust.

Synergy between safety and performance: The multi-layer structure of composite packaging increases the difficulty of recycling, and the migration risk of additives needs to be strictly controlled through migration tests. Residual issues such as fluorescent whitening agents and antioxidants require continuous attention.

Imperfect recycling and circulation system: The efficiency of plastic packaging recycling and sorting is low, and non-food-grade recycled materials are mixed into food packaging production, posing a prominent risk of secondary pollution.

III. Development Trends of Food Packaging Materials

(1) Greenification: Sustainable materials become mainstream

Scale-up of bio-based materials: With the iteration of technologies such as PLA and PHA, costs continue to decline. By 2030, the market penetration rate of bio-based materials is expected to reach 30%, covering 20% of food packaging demand. The CO₂ copolymer technology developed by the Ningbo Institute of Materials, Chinese Academy of Sciences has achieved mass production, with a bio-based content of 90% and a cost reduction of 23% compared to traditional PLA.

Recyclability and Single Materialization: The industry is transitioning towards single-material structures such as PE and PP to enhance recycling efficiency. Paper-based materials are being enhanced with coating technology to improve waterproof and oil-resistant properties, replacing certain plastic applications.

Edible and degradable packaging: Edible packaging materials such as sodium alginate and starch-based products are being piloted in the snack and beverage sectors to reduce waste generation; mushroom mycelium and cellulose-based materials are gradually being used for cushioning packaging.

(II) Functionalization: Dual improvement in performance and safety

High barrier and preservation technology: Nanocomposite materials (such as nanoclay and nano-SiO₂) reduce oxygen transmission rate to below 0.1cc/m²·day, extending the shelf life of food. Antimicrobial coatings and antioxidant coatings are applied in high-end packaging, with the number of related patent applications increasing by 18.5% annually.

Security protection upgrade: Tamper-proof packaging has become an industry standard, with intelligent detection systems monitoring the integrity of the seal in real time to reduce the risk of contamination.
