What is GAG Sheet?

GAG stands for PETG–APET–PETG co-extruded sheet. It combines the advantages of both PETG and APET into a single structure:

• Outer layers (PETG): Excellent printability, strong chemical resistance, and superior bonding performance for heat sealing or gluing.
• Core layer (APET): High rigidity and good formability, keeping costs lower than full PETG sheet.

This three-layer structure makes GAG plastic sheet the ideal material for high-clarity packaging such as clamshells, blisters, and window boxes.

Advantages of GAG Sheet for Thermoforming Packaging

1. Crystal-Clear Transparency
The sheet offers glass-like clarity, ensuring your product is perfectly visible to consumers — an essential factor in retail display packaging.

2. Excellent Thermoforming Performance
Suitable for vacuum forming and pressure forming, GAG sheet maintains high definition in molded details, ideal for complex blister shapes.

3. Superior Printability
The PETG outer layer allows direct printing without pre-treatment, perfect for branding, logos, and product information.

4. Good Bonding & Sealing
Can be sealed with high frequency, heat, or ultrasonic methods, making it widely compatible with different blister packaging processes.

5. Impact Resistance
Strong and durable, reducing damage risk during transportation and handling.

6. Food-Grade Safety
Non-toxic and compliant with FDA and EU food-contact standards, suitable for food clamshell trays and bakery packaging.
