PET Sheet for Thermoforming Applications
Forming Stock Extruded In-House
Every roll and stack of PET sheet for thermoforming on this page is extruded on our own lines in Ganzhou, Jiangxi, where we have produced polyester sheet since 2013. Eight automated lines run about 50 tons a day inside a plant of more than 10,000 m², so a single qualification roll and a standing monthly order can be quoted against the same specification. Thermoformers arrive with the same three questions: what gauge, which grade, and how consistent is the thickness across the web. The sections below answer them in that order.
Selected Material Options
Specification Details to Confirm
- Requested material grade, thickness and thickness tolerance
- Roll width, core size, maximum diameter and winding direction, or cut-sheet dimensions
- Clarity, color, surface treatment and appearance criteria
- Forming-line requirements and the proposed sample-trial plan
- Required test methods, acceptance criteria and grade-specific documentation
Review the quoted material specification with the intended forming line. Confirm process settings through the material guidance and a controlled trial on the intended equipment.
What is the difference between APET and PETG for forming?
Compare the exact APET or PETG grade against the pack design, forming process, clarity, rigidity and joining requirements. For a GAG proposal, confirm the layer structure and grade specification. Review the material guidance and a sample on the intended line before deciding which option meets the agreed requirements.
Samples, Trials and Lead Times
Include the required sample quantity and target delivery date with the material specification. Confirm sample availability, dispatch timing and the proposed production schedule in the quotation. Review the trial on the intended tool for forming depth, trim quality, fit, stacking and denesting, and agree the acceptance criteria before confirming the bulk order.

Application Comparison Checklist
| Decision area | What to compare | Recommended next step |
|---|---|---|
| Pack design | Tray, lid, clamshell or insert geometry, forming depth and intended load. | Send the drawing and any existing sample or acceptance requirements. |
| Forming process | Vacuum, pressure or plug-assist forming and the intended tool and line. | Describe the process and confirm the proposed grade for a sample trial. |
| Feed specification | Thickness and tolerance, roll width, core, maximum diameter and winding direction or sheet-fed blank dimensions. | Provide the forming-line feed specification and requested quantity. |
| Trial criteria | Corner thinning, trim quality, fit, stacking and denesting. | Review a trial on the intended tool against agreed inspection points. |
| Order scope | Grade, feed format, food-contact or ESD requirements where applicable, packing and destination. | Confirm the material specification, required documentation and delivery requirements. |

Grades for Formed Packaging
Specify the function required from the material and review the proposed grade for the intended pack and forming process.
- Clear packaging: define clarity, color and surface-appearance criteria.
- Stacked packs or blanks: describe separation, stacking and denesting requirements.
- Electronics trays: state the required electrical performance, test method and test conditions for the formed part.
- Chilled packaging: describe the intended temperature and condensation conditions for sample evaluation.
- Multilayer material: confirm the proposed layer structure, joining method and trial requirements.
Include any color reference or recycled-content requirement in the specification. Confirm the quoted grade, supporting information and compatibility with the intended equipment through the agreed review and sample trial.
Specification and Procurement Checks
For cup projects, review our PET sheet for disposable drink cups for cup drawings, rim and lid fit, beverage conditions and sample acceptance details.
| Specification area | Recommended check | Buyer note |
|---|---|---|
| Forming process | Thermoforming, vacuum forming or pressure forming. | Share machine width and forming temperature if known. |
| Thickness choice | Based on tray depth, load, rigidity and cutting performance. | Send drawing or existing sample. |
| Material option | APET, PET, PETG or GAG depending on clarity, toughness and forming behavior. | Confirm cost and performance priority. |
| Packing format | Rolls, sheets, palletized loads and protective wrapping. | Confirm unloading and storage requirements. |
What to Send Us for a Quote
- The pack and its forming method - vacuum, pressure or plug-assist - plus the forming depth
- Thickness and the tolerance you need held, or the drawing it comes from
- Roll width and core size, or the sheet size if you form from blanks
- Clarity, color or surface requirement, with a reference if you have one
- Whether food-contact or ESD documentation is required
- Sample quantity and expected annual volume, with the destination port
With those six lines we can quote and ship a sample without a round of clarifying emails. Buyers comparing pet sheets for thermoforming across several suppliers usually find the specification conversation, not the price, is what separates them — which is the main reason we would rather sell PET sheet for thermoforming against a drawing than against a catalogue number.
Food Contact and Documentation
For a food-packaging project, identify the food type, intended contact time and temperature, and destination market. Review documentation for the exact material grade and intended use before approving the specification. Include the forming, sealing and filling process in the sample-review brief, and record the required acceptance criteria before a bulk order.
