Primary Function |
| PET (Polyester) |
Outer Layer (PET/PE) |
12–20 µm |
Provides stiffness, puncture resistance, and excellent print surface |
| BOPP (Bioriented Polypropylene) |
Outer Layer (BOPP/PE) |
20–30 µm |
Offers superior moisture barrier, high clarity, and stiffness |
| PE (Polyethylene) |
Inner Sealing Layer (both) |
50–100 µm |
Ensures strong heat seals, moisture barrier, flexibility at low temperatures |
| Adhesive |
Lamination Layer |
2–5 µm |
Bonds PET/BOPP to PE permanently, resistant to delamination |
Total Pouch Thickness: Typically 65–130 µm, depending on product requirements.

Special Features: Resealable zippers, anti-fog coatings, shaped pouches
Sustainability Profile
- Reduced Material Use: Thinner and lighter than rigid packaging
- Lower Carbon Footprint: Efficient shipping due to lightweight design
- Recyclability Challenges: Multi-material structure limits current recyclability
- Emerging Alternatives: Development of mono-material recyclable options
Ideal Use Cases
Choose PET/PE when:
- High-quality printing and branding are priorities
- Products benefit from slightly better oxygen barrier
- Packaging needs to withstand slightly higher temperatures
Choose BOPP/PE when:
- Maximum moisture barrier is critical
- Product visibility through packaging is important
- Cost efficiency is a primary concern
Limitations & Considerations
- Oxygen Barrier: Moderate – may not be suitable for highly oxygen-sensitive products
- Long-Term Storage: Best for products with ≤18 month shelf life
- High-Fat Products: May require special PE formulations to prevent grease migration
Product Summary
The Frozen Fish & Food Packaging Pouch in PET/PE and BOPP/PE structures offers a practical, economical solution for a wide range of frozen products. While not designed for extended shelf life or high oxygen sensitivity, these pouches deliver reliable performance for standard frozen food applications, combining essential protection with manufacturing efficiency and consumer convenience.
Best Applications
Mainstream frozen food processors, value-oriented brands, private label products, and applications where cost-effective, reliable packaging with adequate protection is required. These structures are particularly suitable for products with moderate shelf-life expectations and standard retail distribution.
