PETG/APET/PETG GAG Sheet Roll for Thermoforming

PETG/APET/PETG GAG Sheet Roll for Thermoforming

HSQY GAG sheet is a three-layer PET-based sheet with a PETG/APET/PETG structure designed for thermoforming, vacuum forming, blister packaging, clear folding boxes, trays and other transparent packaging applications. The PETG surface layers help improve forming and surface performance, while the APET core provides useful rigidity and cost control.

HSQY supplies clear GAG sheet rolls and cut sheets in thicknesses from 0.15mm to 3mm, roll widths from 110mm to 1280mm and standard sheet sizes including 915 × 1220mm and 1000 × 2000mm. Custom widths, sheet sizes, colors, roll configurations and packaging can be discussed for thermoforming companies, packaging converters, folding-box manufacturers and wholesale buyers.

What Is GAG Sheet?

GAG sheet is commonly a three-layer co-extruded PET sheet consisting of PETG outer layers and an APET core. It can be described as PETG/APET/PETG, G-PET-G or an A/B/A structure, where the two outside PETG layers surround the central APET layer.

The structure is designed to combine characteristics of both PETG and APET. PETG surfaces can provide improved toughness, forming behavior, folding and bonding performance, while the APET core helps provide stiffness and reduce the amount of higher-cost PETG required compared with a full PETG sheet.

For this reason, GAG is often considered when standard APET does not provide sufficient forming or folding performance but a full PETG construction is not economically necessary.

GAG Sheet Layer Structure

The exact PETG/APET/PETG layer ratio should be confirmed according to the forming depth, stiffness, folding, sealing or bonding requirement of the finished package.

PET GAG Sheet Specifications

HSQY manufactures GAG sheet in roll and cut-sheet formats for thermoforming, vacuum forming, folding, die-cutting and transparent packaging conversion. Roll configuration should be matched to the buyer's forming equipment and production line.

Key Advantages of GAG Sheet

Improved Thermoforming Performance

The PETG surface layers can provide a more forgiving forming surface than standard APET for selected deep-draw or complex packaging geometries. Final performance depends on layer ratio, sheet thickness, forming temperature, mold geometry and forming equipment.

High Clarity for Display Packaging

Clear GAG sheet provides good product visibility for blister packaging, folding boxes, clamshells and retail display applications where transparency is important.

Balance of Toughness and Rigidity

PETG surface layers can improve toughness and resistance to cracking during folding or forming, while the APET core helps maintain useful stiffness for the finished package.

Better Folding and Bonding Potential

GAG is frequently considered for clear folding boxes and fabricated packaging because PETG surfaces can provide useful folding, gluing and selected heat-sealing characteristics. Adhesive or sealing compatibility should be tested with the buyer's actual production system.

PET-Family Multilayer Construction

PETG and APET are both polyester materials in the PET family. This can simplify the material structure compared with laminates that combine unrelated polymer families. Actual recyclability and acceptance still depend on the finished package, additives, labels, adhesives and local recycling infrastructure.

GAG vs APET vs PETG Sheet

APET, PETG and GAG are all used in transparent thermoforming and packaging, but their structures and processing characteristics are different. GAG is often selected as a middle option when the buyer wants PETG-like surface behavior with an APET core.

GAG Sheet for Thermoforming

GAG sheet is suitable for vacuum and thermoforming applications where the converter requires transparency, useful rigidity and improved resistance to cracking during forming.

Actual forming conditions depend on total thickness, PETG layer ratio, mold depth, heater configuration, machine speed and forming method. Buyers should evaluate samples on their own thermoforming equipment before approving mass production.

Drying requirements can depend on material moisture, storage conditions and processing temperature. Do not assume that every GAG grade or storage condition can always be formed without pre-drying; follow the technical guidance applicable to the supplied grade.

GAG Sheet for Clear Folding Boxes

Clear folding boxes require more than transparency. The sheet must also tolerate scoring, creasing, bending, adhesive bonding and repeated handling without excessive whitening or cracking.

PETG outer layers make GAG attractive for folding-box applications because they can improve surface toughness and folding behavior compared with standard APET. Final crease performance depends on thickness, score geometry, grain direction, processing conditions and box design.

If the box will be glued or heat sealed, provide HSQY with the adhesive type, sealing method and production speed so compatibility can be tested before bulk production.
