What Is Seafood Packaging?
Seafood packaging protects fish, shrimp, shellfish and other aquatic products from oxygen, moisture and temperature abuse from catch to consumer. Because seafood spoils quickly, flexible packaging with high barrier properties, strong seals and cold-chain reliability is essential. Packtastic supplies high-barrier seafood packaging - including vacuum bags and thermoforming films - used by fish processors, exporters and seafood brands around the world.
Seafood Packaging Requirements
- Ultra-low oxygen transmission: fish is highly sensitive to oxidation; high-barrier films prevent rancidity and bacterial growth.
- Excellent seal integrity: strong seals prevent leakage of juices (drip loss) and brine.
- Cold-chain performance: films must remain flexible and strong at freezing temperatures down to -30C.
- Puncture and abrasion resistance: shells, bones and fins can damage thin films.
- Food-contact safety: compliance with FDA/EU food-contact regulations for direct contact with seafood.
Recommended Seafood Packaging Solutions
- Vacuum Bags - PA/PE and PA/EVOH vacuum bags for whole fish, fillets, shrimp and IQF seafood with excellent barrier and clarity.
- PVDC & EVOH Barrier Films & Bags - ultra-high barrier films that minimize oxygen ingress for extended chilled shelf life.
- Thermoforming Films - vacuum skin packaging (VSP) webs that lock fillets and shellfish in a tight, premium presentation.
Material Structures
Recommended structures for seafood packaging:
- PA/PE - all-purpose vacuum bag for chilled and frozen seafood.
- PA/EVOH/PE - maximum oxygen barrier for smoked salmon, sushi and premium fillets.
- PA/PE with PVDC - high-barrier shrink alternative for export packs.
- PE/EVA low-temperature films - flexibility at deep-freeze temperatures.
Seafood Packaging FAQ
How long does fresh fish stay fresh in vacuum packaging?
Chilled fish vacuum-packed in high-barrier bags lasts 8-15 days, depending on initial freshness and temperature control. EVOH-barrier structures provide the longest shelf life.
Can seafood vacuum bags be used for frozen products?
Yes. PA-based vacuum bags remain flexible at -30C, reducing freezer burn and protecting products during frozen storage and transport.
What packaging is best for smoked salmon?
High-barrier vacuum skin packaging (VSP) or PA/EVOH vacuum bags are the industry standard for smoked salmon, preserving color, texture and flavor.
Do you supply printed seafood bags?
Yes, with gravure or digital printing using food-safe inks, including brand artwork, species information and traceability codes.
