HSQY Clear Blister PET GAG Film Sheet

Clear GAG PET Sheet for Blister and Food Packaging

HSQY clear GAG PET sheet is a three-layer PETG/APET/PETG co-extruded sheet developed for transparent blister packaging, thermoformed trays, clamshells, folding boxes and other clear packaging applications requiring a balance of clarity, rigidity, toughness and forming performance.

The GAG structure uses PETG as the two outer A layers and APET as the central B layer. The PETG surfaces support demanding forming, folding, bonding and fabrication requirements, while the APET core provides structural rigidity and helps control material cost compared with using PETG throughout the full sheet thickness.

HSQY currently supplies clear GAG PET sheet in thicknesses from 0.15mm to 3mm, roll widths from 110mm to 1280mm, and cut-sheet sizes including 915×1220mm and 1000×2000mm. Customized thickness, width, sheet dimensions, color and packing can be discussed according to the project.

For food, medical or other regulated packaging applications, buyers should request current product-specific compliance documentation covering the exact resin, GAG structure, additives, intended contact conditions and destination market before commercial use.

What Is GAG PET Sheet?

GAG PET sheet, also called PETG/APET/PETG sheet or G-PET-G sheet, is a co-extruded polyester sheet with a symmetrical A/B/A multilayer structure.

Unlike standard APET sheet, which consists primarily of amorphous PET, GAG adds PETG surface layers. These outer layers can improve processing performance in applications involving deeper thermoforming, folding, bonding, printing or higher resistance to stress whitening and cracking.

Compared with a full PETG sheet, GAG retains an APET core. This makes it useful where PETG-like surface performance is desirable but using PETG throughout the entire thickness is not necessary.

PETG/APET/PETG Three-Layer Structure

For projects where the exact PETG/APET/PETG layer ratio affects forming, sealing or cost, buyers should request the production structure from HSQY rather than assuming a fixed percentage for every GAG grade.

Clear GAG PET Sheet Specifications

The following specifications are based on the current product information. Final tolerance, roll configuration, optical properties, layer ratio and regulatory requirements should be confirmed in the approved purchase specification.

Why Use GAG PET Sheet for Blister Packaging?

High Product Visibility

Clear GAG sheet can provide strong product visibility for retail blisters, clamshells, transparent trays and folding boxes. Where optical quality is critical, buyers should specify measurable haze, light transmission and acceptable surface-defect limits.

Improved Formability Compared with Standard APET

PETG outer layers can provide a more forgiving forming surface for deep cavities, sharp corners and demanding thermoformed package designs. Actual improvement depends on sheet grade, layer ratio, thickness and forming conditions.

Reduced Stress Whitening and Cracking

GAG is worth evaluating when conventional APET shows stress whitening, cracking or poor performance around tight folds and deeply formed areas.

Balanced Rigidity

The APET core contributes rigidity so blister packs, folding boxes and formed trays can retain useful structural stability while benefiting from PETG surface characteristics.

Printing and Decoration

GAG sheet can be evaluated for printed packaging and decorative applications. Ink adhesion depends on sheet surface, ink chemistry, printing technology and any required surface treatment, so production testing is recommended.

Folding and Bonding Performance

PETG surfaces can be advantageous for clear folding-box applications where crease quality, folding behavior and bonding performance are important. Adhesive compatibility should be tested with the actual production material.

PET-Based Material Structure

Both PETG and APET belong to the polyester family. However, actual recyclability of the finished package still depends on local collection and sorting systems, labels, inks, adhesives, coatings and other package components.

Clear GAG PET Sheet Applications

Retail Blister Packaging

Clear GAG sheet can be thermoformed into retail blister cavities for consumer goods, accessories, tools, toys, hardware and other packaged products where product visibility is important.

Clamshell Packaging

GAG can be evaluated for clamshell packs requiring clear appearance, forming performance and resistance to cracking during handling.

Thermoformed Food Trays

Food-contact GAG grades can be evaluated for transparent food trays where the exact resin, additives and layer structure are supported by suitable documentation for the intended food-contact conditions and destination market.

Clear Folding Boxes

Clear GAG sheet is useful for transparent folding cartons for cosmetics, gifts, electronics, stationery, accessories and retail products requiring high product visibility.

Electronics Packaging

GAG can be converted into clear trays, blisters and protective packaging for electronic products. Anti-static or ESD performance should only be claimed where a dedicated grade has been specified and tested.

Printed and Decorative Packaging

Selected GAG sheet can be printed, decorated, cut and fabricated for transparent packaging, promotional displays and decorative plastic components.

GAG vs APET vs PETG for Clear Packaging

When Should You Choose GAG Instead of APET?

GAG should be evaluated when a standard APET package is close to meeting the project requirements but experiences cracking, stress whitening, difficult folding, unreliable bonding or inadequate forming performance.

If conventional APET already provides sufficient forming performance, rigidity and package quality, APET may remain the more economical solution.

When Should You Choose GAG Instead of PETG?

Full PETG is generally preferred where maximum forming flexibility, deep-draw performance, toughness or advanced fabrication performance is more important than raw-material cost.

GAG can be a practical choice where PETG-like surface behavior is needed but a full PETG structure would provide more performance than the application requires.

GAG PET Sheet for Food Packaging

GAG can be produced for transparent food-packaging applications, but the phrase “PET-based” by itself does not prove that every GAG grade is approved for every food-contact condition.

Before purchasing material for food trays or direct food-contact packaging, confirm the exact resin grade, additives, manufacturing specification, food type, contact temperature, contact duration and destination-market requirements.

Request current food-contact declarations or migration documentation applicable to the exact supplied GAG grade rather than relying only on ISO 9001 or a general SGS certificate.

Thermoforming Clear GAG PET Sheet

GAG sheet can be processed using common thermoforming methods, including vacuum forming and application-specific pressure or plug-assist forming. Successful processing depends on sheet thickness, machine design, heater profile, mold geometry and forming depth.

Quality Parameters for GAG Blister Sheet

• Thickness and Tolerance: Important for forming consistency and finished blister rigidity.

• Layer Ratio: Influences cost and the balance between PETG surface properties and APET core rigidity.

• Roll Width Tolerance: Important for automatic thermoforming-line tracking.

• Haze: Important for transparent retail packaging and product visibility.

• Light Transmission: Useful for defining clear packaging quality more precisely than simply stating “transparent.”

• Surface Defects: Define acceptable limits for gels, black spots, scratches, bubbles and contamination.

• Flatness and Curl: Important for sheet-fed printing, folding and forming.

• Impact Performance: Test according to the actual blister or finished package requirement.

• Forming Performance: Validate on the intended thermoforming equipment and mold.

• Printing / Bonding: Test with the actual ink, adhesive or sealing process.

How to Choose Clear GAG PET Sheet

1. Define the Finished Package

Specify whether the finished product is a blister, clamshell, food tray, folding box, insert, electronic package or another transparent thermoformed product.

2. Select the Required Thickness

HSQY currently lists 0.15–3mm. Select the gauge according to cavity depth, package size, rigidity, load and conversion method.

3. Confirm Roll or Sheet Format

Roll-fed thermoforming lines require slit width, core diameter, maximum roll diameter and maximum roll weight. Folding boxes and sheet-fed fabrication normally require cut-sheet dimensions and flatness control.

4. Provide Forming Depth and Product Drawing

Deep cavities, sharp corners and narrow radii increase material stretch and should be evaluated using the actual package drawing or tooling information.

5. Define Optical Requirements

For premium transparent packaging, specify haze, transmission, color and acceptable visual defects rather than using only a general “high clarity” requirement.

6. Confirm Printing, Folding or Bonding

Tell HSQY whether the material will be printed, creased, folded, glued, heat sealed or otherwise converted after extrusion.

7. Confirm Food-Contact Requirements

If direct food contact is required, provide the food type, contact temperature, use conditions and target country so current product-specific documentation can be checked.
