Offline Lamination Films for Thermoforming Sheets
CPP Film, PE Film, PE/EVOH/PE Barrier Film and Functional Films for Laminated Packaging
WANSYN supplies offline lamination films for thermoforming sheets, including CPP film, PE film, PE/EVOH/PE high-barrier film, printed film, anti-fog film, easy-peel film, easy-tear film and skin pack related functional films.
These films are laminated onto PET, PP, PS or other base sheets after sheet extrusion to build functional laminated sheets for food packaging, high-barrier packaging, sealing applications and thermoforming trays.
Typical applications include meat trays, seafood trays, sushi boxes, ready meal trays, frozen fish packaging, MAP trays, VSP / Skin Pack trays, candy packaging, chocolate inserts and premium food packaging.
Quick Answer: What Is Offline Lamination Film?
Offline lamination film is a functional film laminated onto a base sheet after sheet production. It is used to add specific packaging functions such as barrier performance, heat sealing, easy-peel opening, anti-fog clarity, printing, decoration or skin pack compatibility.
Common offline lamination films include:
· CPP film
· PE film
· PE/EVOH/PE high-barrier film
· Printed CPP / PE film
· Anti-fog film
· Easy-peel film
· Easy-tear film
· Skin pack related functional film
Compared with online PET-to-PET thermal lamination, offline lamination offers more flexibility for multi-material and multi-functional structures.
1. CPP Film for Offline Lamination
CPP film is widely used in offline lamination for thermoforming sheets. It can provide sealing performance, flexibility, printability and surface function depending on the film structure.
Typical CPP film options:
· Printed CPP film
· Gold / silver effect CPP film
· Sushi pattern CPP film
Common laminated structures:
· PET/CPP
· PP/CPP
· PS/CPP
· PET/Printed CPP
· PP/Printed CPP
Typical applications:
· Sushi boxes
· Food trays
· Candy packaging
· Chocolate tray inserts
· Bakery and dessert packaging
· Chilled food packaging
· Decorative thermoforming trays
CPP film is often selected when the packaging needs better sealing performance, decorative printing, flexible lamination structure or improved surface function.
2. PE Film for Offline Lamination
PE film is commonly used as a sealing layer or functional inner layer for laminated thermoforming sheets. It can help improve sealing performance, moisture resistance, easy-peel opening and food packaging compatibility.
Typical PE film options:
· Transparent PE film
· Easy-peel PE film
· Easy-tear PE film
· Printed PE film
· PE-based functional film
Common laminated structures:
· PET/PE
· PP/PE
· PS/PE
· PET/Printed PE
· PP/PE sealing layer
Typical applications:
· Meat trays
· Seafood trays
· Deli food trays
· Ready meal trays
· Salad boxes
· Frozen food packaging
· Lidding and sealing applications
PE film is often selected when the packaging requires stable sealing, easier opening, better moisture protection or compatibility with sealing films.
3. PE/EVOH/PE High-Barrier Film
PE/EVOH/PE film is a common high-barrier film used for offline lamination when oxygen barrier performance and shelf-life support are required.
EVOH provides oxygen barrier performance, while PE layers help support sealing, processing and food-contact surface requirements.
Typical functions:
· High oxygen barrier
· MAP packaging support
· Shelf-life extension
· Sealing layer support
· Food packaging compatibility
· Meat and seafood packaging protection
Common laminated structures:
· PET + PE/EVOH/PE
· PP + PE/EVOH/PE
· PS + PE/EVOH/PE
· PET/EVOH/PE based functional sheet
· Barrier bottom web for MAP packaging
Typical applications:
· MAP meat trays
· Seafood trays
· Fresh food trays
· Ready meal trays
· Cheese and deli packaging
· Frozen fish packaging
· High-barrier thermoforming sheets
For high-barrier packaging, final performance should be evaluated after thermoforming. Forming depth, corner thinning, sealing integrity, microleaks, OTR, WVTR and storage conditions can all affect the final packaging result.
4. Easy-Peel and Easy-Tear Films
Easy-peel and easy-tear films are used when the final package requires clean opening, controlled peel force or better consumer experience.
Typical functions:
· Clean opening
· Stable peel strength
· Reduced tray tearing
· Better consumer experience
· Suitable sealing window
· Compatibility with lidding film
Typical applications:
· Ready meal trays
· Meat trays
· Seafood trays
· Salad boxes
· Deli food packaging
· Premium food trays
Easy-peel and easy-tear performance should be tested together with the base sheet, lidding film, sealing temperature, pressure, dwell time and target peel force.
5. Anti-Fog Films
Anti-fog films are used for chilled display packaging where product visibility is important. They help reduce fogging caused by temperature differences and condensation.
Typical applications:
· Sushi boxes
· Seafood trays
· Meat trays
· Salad boxes
· Chilled food trays
· Fresh fruit packaging
· Dessert boxes
Anti-fog performance depends on film structure, surface treatment, storage temperature, humidity, condensation conditions and final packaging design. Real-condition testing is recommended.
6. Skin Pack / VSP Related Functional Films
Skin Pack and VSP packaging require system matching between the bottom tray or bottom web, top skin film, sealing layer, machine parameters and product shape.
Offline lamination can help build bottom sheet structures with suitable sealing, barrier, low-temperature or surface compatibility.
Typical applications:
· Frozen fish skin pack packaging
· Seafood VSP trays
· Meat skin pack trays
· Premium chilled food packaging
· High-barrier bottom web materials
7. Printed and Decorative Films
Printed CPP film, printed PE film and decorative films can be used to improve shelf appeal and brand recognition.
Available options:
· Sushi pattern film
· Food pattern film
· Wood grain film
· Gold effect film
· Silver effect film
· Customized printed film
· Logo printed film
· Seasonal promotional design
Typical applications:
· Sushi boxes
· Japanese food trays
· Candy packaging
· Chocolate inserts
· Dessert packaging
· Premium food trays
· Gift packaging inserts
Printed and decorative films should be evaluated for color stability, lamination strength, scuff resistance, pattern distortion after forming and food packaging suitability.
Why Choose Offline Lamination?
Offline lamination is suitable for packaging projects that need more complex functions than a single base sheet can provide.
It can help build thermoforming sheets with:
· High barrier performance
· Heat sealing performance
· Easy-peel opening
· Easy-tear function
· Anti-fog clarity
· Skin pack compatibility
· Printed or decorative appearance
· Better functional layer design
· Multi-material structure flexibility
For projects involving MAP packaging, VSP packaging, easy-peel sealing, anti-fog display or high-barrier food packaging, offline lamination is often a more flexible solution.
