GAG Sheet Series

High Quality Clear Transparent PETG-APET-PETG Composite GAG Sheet

The Clear Transparent PETG-APET-PETG Composite GAG Sheet is a state-of-the-art laminated sheet engineered for unparalleled performance and sustainability. Its unique three-layer "GAG" structure features two tough and clear PETG outer layers encapsulating a high-strength, rigid APET core. This design delivers the perfect synergy of surface durability, structural integrity, and 100% mono-material recyclability.

✔ Unmatched Durability & Clarity: PETG outer layers resist scratches, chemicals, and impacts while maintaining >90% light transmittance for a crystal-clear, glass-like finish.

✔ Superior Rigidity & Dimensional Stability: The APET core provides exceptional stiffness and flatness, preventing warping and ensuring precise fabrication.

✔ 100% Recyclable & Eco-Friendly: As a true mono-material (all layers are PET-based), the entire sheet is easily recyclable in standard PET/PETG streams, supporting circular economy goals.

✔ Optimal for Thermoforming: The "GAG" structure provides a wider and more stable thermoforming window than single-layer sheets, resulting in deep-drawn parts with uniform wall thickness and no whitening.

✔ Enhanced Barrier Properties: The APET core offers improved resistance to moisture and gases compared to single-layer PETG.

Provide high-quality Clear Transparent Composite GAG sheet and roll materials

Description

Our Clear Transparent PETG-APET-PETG Composite GAG Sheet represents a breakthrough in engineered plastic sheeting. This isn't a simple blend, but a precision-coextruded laminate. The outer layers of Glycol-Modified PET (PETG) are chosen for their toughness, formability, and excellent surface quality. They protect the inner Amorphous PET (APET) core, which contributes high tensile strength and rigidity.

This construction is specifically designed to overcome the limitations of single-material sheets. It provides the deep-draw capability and surface resilience of PETG, combined with the load-bearing strength and stability typically associated with thicker, less formable materials like polycarbonate. It is the ideal choice for applications requiring a combination of optical clarity, structural performance, and environmental responsibility.

Customer Testimonials

“

Switching to this GAG sheet for our premium skincare packaging was a game-changer. We achieved the deep-draw depth we needed for our unique design, the clarity is stunning, and our marketing team loves the strong sustainability story.

“

The rigidity of this composite sheet solved the warping issue we had with standard PETG in our large-format medical trays. It runs perfectly on our forming lines and meets all our sterilization protocols.

Frequently Asked Questions

Q: What does "GAG" stand for in this context?

In sheet extrusion, "GAG" is a common industry abbreviation describing a 3-layer symmetrical structure: a Glycol-modified (PETG) outer layer, an Amorphous (APET) core, and another Glycol-modified (PETG) outer layer. It describes the material sequence.

Can this sheet be recycled?

Yes, seamlessly. This is its key environmental advantage. Since all three layers are PET-based polyesters (PETG and APET are chemically compatible), the entire sheet can be recycled together in PET recycling streams without the need for separation, unlike traditional multi-material laminates.

Is it more difficult to thermoform than regular PETG?

Not at all. In fact, many users find it more forgiving. The APET core provides a wider and more stable "forming window," allowing for consistent molding of deep-draw parts. The processing temperatures are similar to those for standard PETG.

What are the main benefits compared to a single-layer PETG sheet of the same thickness?

The primary benefits are greatly increased rigidity (stiffness), superior flatness, and reduced warpage. You get the surface and forming benefits of PETG with the structural performance closer to a thicker or more rigid material, often allowing for downgauging (using a thinner sheet) to achieve the same performance.

Do you offer anti-fog or anti-static versions?

Yes. We can apply permanent anti-fog coatings to the surface or incorporate anti-static additives into the composite structure for applications like refrigeration packaging or electronics handling. Please inquire for these specialized grades.
