We manufacture custom frozen food packaging bags tailored for seafood processors. They are a practical choice for frozen storage vacuum packaging, effectively delaying oxidation and maintaining seafood freshness.
Material Analysis of Vacuum Pouches
Introduction to NY/PE Composite Material
- Nylon/PE (NY/PE) is a popular two-layer co-extruded composite film widely applied for frozen food vacuum packaging.The nylon (NY) layer delivers strong tensile strength and outstanding puncture resistance, which can withstand sharp fish bones, seafood shells and irregular food edges during vacuum sealing and freezing.
- The inner PE layer provides stable heat-sealing performance. It ensures tight sealing under common vacuum machine temperature settings and prevents leakage during long-distance cold chain transport.
Common Applications of Nylon/PE Vacuum Pouches
Frozen Seafood
These nylon/PE pouches are the preferred choice for salmon, cod, shrimp and shellfish. Great puncture resistance stops sharp fish bones piercing the film during vacuum processing and low-temperature storage. They are ideal solutions for frozen storage vacuum packaging in seafood processing plants.
Frozen Meat & Cooked Meat
Suitable for beef steaks, pork, lamb, bacon and smoked meat. The nylon layer resists jagged bone edges, while reliable heat seal locks in flavor and avoids freezer burn. Many factories order custom frozen food packaging bags of this material for meat production lines.
Processed Ready-to-Eat Food
Vacuum-packed deli food, marinated products and ready meals also widely adopt nylon/PE frozen packaging bags. The multi-layer structure slows oxidation and extends shelf life under refrigeration or freezing conditions.

Material Options for Salmon Packaging & Comparison of Pros and Cons
1. NY/PE (Nylon/PE)
Durable NY PE High Barrier Vacuum Bags for Frozen Seafood belong to this material series, the most mainstream choice for salmon factories.
✅ Advantages: Excellent puncture resistance, stable heat sealing, suitable for products with fish bones; moderate cost, ideal for frozen storage vacuum packaging.
❌ Disadvantages: Medium oxygen barrier, not recommended for storage longer than 12 months.
2. PET/NY/PE Three-layer Composite
✅ Advantages: Higher oxygen & moisture barrier than NY/PE, stronger anti-puncture performance, support long-term freezing preservation. Many clients customize these custom frozen food packaging bags for high-end smoked salmon.
❌ Disadvantages: Higher raw material cost than two-layer NY/PE.
3. PET/PE Two-layer Composite
✅ Advantages: Lowest cost among common vacuum materials, good flat appearance.
❌ Disadvantages: Poor puncture resistance. Sharp salmon bones easily pierce the film. Only fit boneless salmon fillets without bone edges.
4. PA/EVOH/PE High Barrier Co-extruded Film
✅ Advantages: Ultra-high barrier, outstanding anti-oxidation, extend salmon shelf life greatly.
❌ Disadvantages: Premium price; strict requirements on storage environment of raw film, small factories rarely select this material for mass production.
5. Aluminum Foil Composite (PET/AL/NY/PE)
✅ Advantages: Complete light shielding, top-level barrier, best choice for smoked salmon sensitive to light.
❌ Disadvantages: Opaque, buyers cannot view products inside bags; higher cost.
Suggestion for salmon packaging:
Boneless salmon fillet → PET/PE or NY/PE
Salmon with bones / portioned salmon steak → NY/PE (cost-effective) or PET/NY/PE
Long-term frozen & smoked salmon requiring light protection → Aluminum foil composite bags
