The $1.7 Trillion Spoilage Crisis
Global food waste costs exceed $1.7 trillion annually, with meat and seafood accounting for 26% of losses due to rapid oxidation and microbial growth. Traditional packaging fails to address critical challenges:
- Myoglobin oxidation turns fresh pork gray within 3-5 days
- *Shewanella* spp. proliferates in fish burgers within 72 hours
- Minced beef sees microbial counts surge >7 log CFU/g in 10 days
Zhucheng Huasu Packing Co., Ltd. – a Weifang-based innovator since 1993 – solves these problems through advanced co-extrusion technology. Our 10,000 ㎡ facility houses 8 automated production lines, including American-engineered 5-layer co-extrusion systems processing Japanese specialty resins. The result? Barrier films that outperform industry standards by 300%.

1. Do Chitosan-Propolis Films Delay Minced Beef Oxidation?
*Science Meets Scalable Manufacturing*
University studies confirm chitosan films with 2% ethanolic propolis extract (EPE) achieve remarkable results:
- Microbial reduction: 5.5 log CFU/g
- Protein carbonyl content decrease: 38% over 14 days
Zhucheng Huasu's industrial adaptation:
We've translated this chemistry into commercially viable solutions using our 7-layer co-extruded films:
Real-world performance:
Minced beef packed in our films maintains:
- Acceptable microbial levels (<4 log CFU/g) for 21 days at 4°C
- Bright red color (a* value >14.5) 60% longer than industry standard

2. Can Lactoperoxidase (LPS) Systems Preserve Fish Burgers?
*Extending Shelf Life Through Precision Engineering*
Laboratory results show chitosan-LPS films:
- Suppress *Shewanella* spp. by 99%
- Extend shelf life by 5 days
Zhucheng Huasu's manufacturing edge:
Our 6-color printing + dry lamination line creates precision LPS-delivery systems:
1. Base substrate: 120μm co-extruded film (OTR: 0.3 cc/m²/day)
2. LPS reservoir: Micro-encapsulated enzyme layers
3. Controlled release: Humidity-triggered diffusion pores
Validation case (2023):
A Shandong seafood processor using our films achieved:
- Reduced spoilage rates: From 12% to 3.2%
- Extended distribution radius: +500 km
- Shelf life: 19 days vs. 14 days for competitor films

3. Why Multilayer Co-Extrusion Dominates Processed Meat Packaging
*The Zhucheng Huasu Advantage*
Conventional films fail because:
❌ Single-layer structures allow O₂ ingress >5 cc/m²/day
❌ Inconsistent thickness causes seal failures
Our 7-layer solution:
Performance benchmarks:
- High-temp films: Withstand 121°C sterilization (ideal for cooked meats)
- Low-temp films: Maintain integrity during 100°C sous-vide processing
- Vacuum retention: <0.1% leakage after 30 days (tested per ASTM D3078)
