Multilayer Film for Strength, Barrier, and Performance
In the world of high-performance packaging, coextruded film stands out as a powerful solution for products requiring strength, durability, and barrier protection — without the bulk or cost of laminated alternatives.
At Sunrise Packaging Films, we specialize in coextruded packaging that combines multiple polymer layers into a single, seamless structure, engineered for vacuum sealing, thermoforming, and form-fill-seal operations.
Coextruded packaging is made by simultaneously extruding multiple layers of polymers into a single film during the manufacturing process. Each layer performs a specific function — such as providing strength, barrier, adhesion, or sealability — resulting in a high-performance packaging material with consistent quality.
Unlike laminated films that bond layers with adhesives, coextruded films are fused during production for greater structural integrity and improved cost-efficiency.
Common Layer Functions in Coextruded Film
-
Outer Layer – Print surface or abrasion resistance - Core Barrier Layer – Oxygen, moisture, or UV barrier (e.g. EVOH)
- Tie Layers – Bonding between dissimilar polymers
- Inner Seal Layer – Heat-sealable surface for forming or sealing
By customizing each layer, Sunrise Packaging Films tailors the film to your product’s requirements, whether it’s shelf life, appearance, or machine compatibility.
Advantages of Coextruded Packaging
- Seamless multi-functionality in a single film
- Consistent gauge and performance across runs
- Lower material cost than laminates
- Excellent formability and sealing behavior
- Reduced risk of delamination
-
Compatible with high-speed FFS equipment - Available in recyclable and sustainable formats
Ideal Applications for Coextruded Films
- Fresh, frozen, and processed meats
- Cheese, deli, and dairy products
- Poultry and seafood
- Bakery and snack foods
- Medical trays and kits
- Pet food and veterinary products
- Industrial and hardware packaging
Whether you need deep-draw thermoforming film or a high-barrier VFFS rollstock, we can build a film structure that delivers performance and savings.
Coextruded vs Laminated Film: What’s the Difference?
| Feature | Coextruded Film | Laminated Film |
|---|---|---|
| Construction | Fused during extrusion | Layers bonded with adhesives |
| Barrier Consistency | Very high | Variable |
| Risk of Delamination | Low | Medium |
| Cost | Typically lower | Higher |
| Use Case | FFS, vacuum, MAP | Premium or specialty needs |
Custom Coextruded Film from Sunrise Packaging Films
We engineer coextruded films using materials like:
- Nylon (PA) for strength and puncture resistance
- EVOH for oxygen barrier
- PE and PP for sealing and flexibility
- PET for clarity or stiffness
- Tie resins for layer adhesion
Each film is tailored for your machine, draw depth, sealing method, and regulatory needs. We offer both formable and non-forming options, in thicknesses ranging from 2 mil to 12 mil.

FAQ: Coextruded Packaging
How many layers are typical in coextruded film?
Most coextruded films range from 3 to 9 layers, depending on the product’s needs for strength, barrier, and sealing performance.
Can coextruded film be printed?
Yes — our outer layers are optimized for high-quality flexographic and rotogravure printing, up to 10 colors.
Is coextruded packaging recyclable?
We offer mono-material coextruded films designed for recyclability. Ask us about options that support your sustainability goals.
