Medium Barrier Seafood Skin Packaging Film is a transparent multilayer film designed for vacuum skin packaging of chilled and frozen seafood. During the skin packaging process, the heated film forms closely over the product and seals to a compatible tray, board or bottom web.
The film combines medium barrier performance with controlled forming, heat sealing and clear product visibility. It is suitable for fish fillets, shrimp, prawns, shellfish and portioned seafood requiring close product coverage and a defined skin-pack format.
Key Features
Medium Barrier Structure
The multilayer construction provides controlled oxygen and moisture protection for seafood applications specified for medium barrier performance.
Controlled Skin Forming
The heated film follows the seafood profile and bottom substrate, supporting close coverage around flat fillets, portions and shaped products.
High Transparency
The clear film keeps the seafood visible through the package, supporting direct inspection of product color, shape and presentation.
Consistent Sealing
The sealing layer is selected according to the required bottom substrate, package structure and processing conditions to support a continuous package seal.

Seafood Applications
Fish Fillets
Suitable for salmon, white fish and other fillet products requiring close film coverage and clear product presentation.
Shrimp and Prawns
Suitable for individual or portioned shrimp products where controlled forming and continuous sealing are required around the product profile.
Shellfish
Suitable for selected shellfish formats requiring close film contact, visible product presentation and a defined package seal.
Frozen Seafood
Suitable for frozen seafood formats requiring skin-tight coverage and film flexibility during cold-chain handling and storage.
Forming & Sealing Performance
Controlled Heating
The film is heated before vacuum forming to reach the flexibility required for controlled draping over the seafood and bottom substrate.
Product Conformity
Vacuum pressure draws the softened film toward the product surface, creating close contact around the seafood profile.
Seal Formation
The sealing layer bonds with the specified tray, board or bottom web to form the package perimeter.
Package Integrity
Film gauge, sealing layer and forming conditions are matched to the package structure to support consistent sealing during normal handling.
Tray & Bottom Web Compatibility
Rigid Trays
The film can be specified for compatible rigid tray structures according to the sealing surface and required packaging format.
Board-Based Formats
For board-based skin packs, the film sealing layer is selected according to the coated or treated surface of the board.
Bottom Webs
Film selection can be matched to compatible flexible or semi-rigid bottom webs according to package dimensions and sealing requirements.
The final film and substrate combination should be confirmed through packaging trials before regular production.
Manufacturing Process
Multilayer Co-Extrusion
Functional polymer layers are co-extruded to establish the required combination of barrier, forming and sealing properties.
Thickness Control
Film gauge is monitored during extrusion to maintain the specified thickness across the production width.
Slitting and Winding
Finished film is converted into specified widths, roll lengths and core configurations for packaging operations.
Finished Roll Inspection
Roll appearance, winding condition, dimensions and specified film characteristics are checked before packing.
Quality Control & Testing
Gauge Inspection
Film thickness is measured against the specified gauge to maintain material consistency across production batches.
Physical Property Testing
Tensile strength and elongation are checked according to the applicable product specification.
Optical Inspection
Film transparency, surface condition and visible appearance are inspected during finished-product control.
Seal Testing
Sealing performance is evaluated with the specified bottom substrate to verify the required package seal.
Forming Evaluation
Skin-forming behavior is assessed according to film thickness, seafood profile and packaging structure.
Food Contact Safety
The film is manufactured for food packaging applications, with applicable food-contact documentation available according to the specified product and destination market.
Food-contact requirements are reviewed against the final film structure, intended seafood application and applicable market requirements before production.
Customization
Film Thickness
Thickness can be selected according to seafood profile, forming depth and required packaging structure.
