PET/AlOx-PET/PE Packaging Bag & Film: High Barrier Transparent Packaging Solution & Applications

Transparent high-barrier packaging has become a favored option for high-end goods amid upgraded global packaging standards. PET/AlOx-PET/PE is an advanced multi-layer composite packaging material, integrating outstanding transparency, powerful barrier capability, sturdy mechanical performance and reliable food-grade safety.

Different from opaque traditional aluminized packaging, it adopts aluminum oxide coating technology. It keeps glass-like clarity while effectively blocking oxygen, moisture and odor, making it widely applied in scenarios that demand long preservation time, attractive product presentation and rigorous safety specifications.

Basic Structure of PET/AlOx-PET/PE Packaging

This three-layer laminated film consists of functional layers with respective features:

1. Outer PET Layer 
It boasts great rigidity, tensile strength and printability. It shields packages against scratch and external damage, ideal for brand printing and commercial display.

2. Core AlOx-PET Barrier Layer 
Nano-scale aluminum oxide is coated on PET surface to form the core protective layer. The invisible coating brings excellent barrier effect without blocking sight. It inhibits oxidation, damp deterioration and flavor loss thoroughly.

3. Inner PE Sealing Layer 
Made of food-grade material, it can directly contact products safely. Featuring stable heat sealing property and low temperature resistance, it seals bags tightly to prevent leakage and contamination during storage and delivery. 

Core Competitive Advantages

Superior Barrier Performance

The nano alumina coating achieves extremely low air and moisture permeability. It extends product shelf life 2 to 5 times longer than regular PET/PE bags, effectively solving food spoilage, mildew and flavor fading issues.

Crystal Clear Visual Effect

Free of metallic shading, the transparent design fully shows product appearance and texture, boosting shelf appeal and attracting consumer attention.

Broad Temperature Adaptability

The material works steadily at temperature ranging from -40°C to 120°C. It fits freezing storage, refrigeration, room temperature placement and pasteurization, satisfying various storage and processing needs.

Safe & Eco-friendly Property

No harmful metal migration exists, complying with international food safety regulations. Compared with aluminum foil packaging, it is easier to recycle and conforms to sustainable packaging trends.

Durable Mechanical Quality

Great resistance against puncture, tear and pressure suits high-speed automatic packaging production and long-distance transportation, lowering damage risks.

Wide Range of Industrial Applications

With all-round reliable performance, this composite packaging serves multiple high-standard industries:

Food Industry

It is the optimal packaging choice for fresh-preserved goods, including coffee, tea, nuts, chocolate, dried snacks, vacuum meat, seafood, ready meals, cooked food, condiments and honey. It locks original taste and keeps items fresh for longer periods.

Pharmaceutical & Healthcare Field

Suitable for health supplements, medical devices and medicine packaging. High barrier performance avoids damp and air pollution, maintaining stable quality and safety of medical supplies.

Cosmetics & Daily Chemicals
