Multi-Layer Frozen Food Packaging with Oxygen Barrier and Temperature Resistance for Cold-Chain Protection
Overview
An Advanced Multi-Layer Frozen Food Packaging Pouch is a high-performance flexible packaging solution engineered specifically to protect frozen food products throughout the entire cold chain. Through intelligent material combinations and sophisticated lamination technology, this packaging format provides exceptional barrier protection, physical durability, and marketing appeal for frozen products ranging from vegetables and seafood to ready meals and premium desserts.
Materials Used
These pouches utilize specialized polymer films selected for their complementary properties:
- PET (Polyethylene Terephthalate): Provides exceptional strength, clarity, and print receptivity; typically serves as the outer layer.
- BOPP (Biaxially Oriented Polypropylene): Offers excellent moisture barrier, stiffness, and high-gloss surface for vibrant printing.
- PE (Polyethylene): Supplied as LDPE, LLDPE, or HDPE variants; delivers reliable heat-seal performance, flexibility, and moisture resistance as the inner layer.
- EVOH (Ethylene-Vinyl Alcohol): Provides superior oxygen barrier when dry; often incorporated as a middle layer in oxygen-sensitive applications.
- PA (Polyamide/Nylon): Enhances puncture and abrasion resistance while improving overall gas barrier properties.
- Metallized Layers: Aluminum vapor deposition on PET or BOPP for enhanced light, oxygen, and moisture barriers.
Typical Film Structures
Multi-layer constructions are achieved through adhesive lamination, extrusion lamination, or co-extrusion processes:
Common Laminate Structures:
- 3-Layer: PET // Adhesive // PE (balanced performance for general frozen goods)
- 4-Layer: BOPP // EVOH // Tie Layer // PE (enhanced oxygen barrier for sensitive foods)
- 5-Layer: PET // Metallized Layer // PA // Tie // PE (premium protection for extended shelf life)
Typical Thickness Range: 60-150 microns total, with individual layer thickness optimized for specific functional requirements.
Common Applications
- Frozen Fruits & Vegetables: Preserves texture and prevents dehydration
- Ready Meals & Prepared Foods: Maintains flavor integrity and prevents freezer burn
- Seafood & Meat Products: Protects against oxidation and odor migration
