GAG Plastic Sheet Roll for Thermoforming

GAG plastic sheet roll is a three-layer co-extruded PET sheet (PETG outer layers + APET core) supplied in continuous roll form for direct feeding into thermoforming machines and packaging conversion lines. Roll-format supply is the standard way thermoforming factories and packaging converters receive GAG sheet, because it allows continuous, high-speed forming without the interruption of loading individual cut sheets.

This page specifically covers GAG sheet in roll format for thermoforming and packaging applications. For a general overview of GAG sheet properties, layer structure, and the comparison with APET and PETG, see our GAG plastic sheet category page.

ONE Plastic manufactures GAG sheet roll on advanced three-layer co-extrusion lines and supplies it to thermoforming factories, packaging converters, and folding box producers worldwide.

Why Roll Format for Thermoforming?

Thermoforming factories and packaging lines specify roll-format GAG sheet for practical production reasons.

Continuous Feeding: Roll supply allows uninterrupted feeding into inline thermoforming machines. The roll unwinds directly into the heating station, so the forming process runs continuously without stopping to load individual sheets. This maximizes machine uptime and output rate.

Less Material Waste: Rolls can be ordered in widths that match your forming tool layout, minimizing edge trim waste. Custom widths reduce the need for secondary slitting or cutting at your facility.

Consistent Tension and Tracking: Roll-format material feeds more consistently through thermoforming equipment than individual sheets, which can shift or misalign during loading. This helps maintain forming accuracy and reduces reject rates.

Efficient Storage and Handling: Rolls are compact relative to the amount of material they contain. A single pallet of GAG rolls holds significantly more forming area than the same pallet space loaded with cut sheets.

Compatible with Inline Systems: Roll supply is required for inline thermoform-fill-seal systems and high-speed packaging lines where the forming, filling, sealing, and cutting operations happen in sequence on one machine.

Thickness Guide for Thermoforming Applications

The right thickness depends on your forming depth, part rigidity requirements, and packaging design. We can provide sample rolls for forming trials on your equipment.

Applications

Thermoformed Food Packaging

GAG sheet roll is widely used in thermoformed food packaging where the finished tray, container, or lid needs to be HF-sealed or glued:

• Fresh produce trays and containers

• Bakery display boxes and cake domes

• Deli containers and prepared meal trays

• Fruit and vegetable clamshells

• Thermoformed lids for cold food packaging

The PETG outer layers allow the thermoformed part to be HF-sealed (which standard APET cannot do) while the APET core keeps the material cost lower than full PETG.

Folding Box Packaging

GAG sheet roll is converted into folding boxes for cosmetics, electronics, toys, and consumer goods. The PETG surface layer resists stress-whitening at fold lines, keeping the crease areas clear and transparent - a critical advantage over APET for folding box applications.

HF-Sealed Clamshell and Blister Packaging

High-frequency sealed packaging for electronics, hardware, and consumer goods. Roll-format GAG sheet feeds directly into inline form-and-seal equipment. The PETG outer layer provides the dielectric response needed for clean HF welds.

Display Trays and Point-of-Sale

Thermoformed product display trays and POS packaging where visual clarity and structural rigidity are both important.

Thermoforming Performance

GAG sheet roll is designed for reliable performance on standard thermoforming equipment:

Pre-drying is important. Moisture absorbed during storage can cause bubbles, haze, or surface defects during thermoforming. We recommend drying at 65 C for 2-4 hours before processing, especially in humid climates.

Roll Specifications and Custom Options

ONE Plastic can customize roll specifications to match your thermoforming equipment and production requirements:

Width Matching: We can produce rolls in the exact width your thermoforming tool requires, reducing edge trim waste. Custom widths between 300mm and 1400mm are available.

Thickness Control: Tight thickness tolerance across the roll helps ensure consistent forming depth and wall thickness in the thermoformed parts.

Core Size: Standard 3-inch (76mm) paper core. If your unwinding equipment requires a different core size, contact our team to arrange a custom core.

Roll Length: Roll length can be adjusted based on your preferred roll weight and machine capacity.

Frequently Asked Questions

Why choose GAG sheet roll instead of cut sheets for thermoforming?

Roll format allows continuous feeding into thermoforming machines, maximizing production speed and minimizing downtime from sheet loading. Rolls can also be ordered in custom widths to reduce edge trim waste. Cut sheets are more suitable for sheet-fed forming on smaller equipment or for non-forming applications.

What is the difference between GAG and APET for thermoforming?

Both are PET-family materials used in thermoforming. GAG has PETG outer layers that provide HF sealing compatibility and resistance to stress-whitening at fold lines. APET is less expensive but cannot be HF-sealed and may stress-whiten during aggressive forming. GAG is preferred for HF-sealed packaging, folding boxes, and deep-draw applications.

What roll widths are available?

We offer roll widths from 300mm to 1400mm. Custom widths matched to your thermoforming tool layout are available to help reduce material waste.

Do I need to pre-dry GAG sheet roll before thermoforming?

Pre-drying is recommended, especially in humid environments. PET-family materials are hygroscopic and can absorb moisture during storage. Drying at 65 C for 2-4 hours before forming helps prevent bubbles, haze, and surface defects.

What thicknesses are available?

We offer GAG sheet roll in thicknesses from 0.15mm to 2.0mm. The most common range for packaging thermoforming is 0.25mm-0.80mm.

What is the minimum order quantity?

Contact our sales team for current MOQ based on your required thickness, width, and roll length.
