Product Overview: Dry Fish Vacuum Packaging  

Dry fish vacuum packaging is designed to protect dehydrated fish products from moisture, oxygen, and physical damage during storage and transportation. Key applications include:  

- Dried Fish Products: Salted fish, stockfish, jerky, and smoked fish.  

- Seafood Snacks: Packaged dried squid, anchovies, and shrimp.  

- Bulk Export: Vacuum-sealed boxes or pouches for international logistics.  

Core Advantages:  

- Extended Shelf Life: Ultra-low oxygen and moisture transmission rates prevent spoilage and rancidity.  

- Puncture Resistance: Protects against sharp fish bones and edges.  

- Tamper-Evident Seals: Ensures product integrity and consumer safety.  

- Sustainability: Recyclable and mono-material options available.
