Clear PETG sheet is a transparent, glycol-modified polyethylene terephthalate plastic sheet known for its high impact resistance, optical clarity, and excellent thermoformability. Compared to standard APET, PETG offers superior toughness — it resists cracking and stress-whitening during forming, making it the preferred material for deep-draw thermoforming, folding boxes, and packaging applications that require both visual clarity and structural durability.
ONE Plastic is a leading PETG sheet manufacturer in China. We produce clear PETG sheets using high-quality imported PETG resin and advanced co-extrusion lines, delivering consistent transparency, surface gloss, and mechanical performance across production batches. Our clear PETG sheets are available in thicknesses from 0.15mm to 6mm, with custom sizing, cutting, and thermoforming services. Food-contact compliance documentation is available on request.

Properties of Clear PETG Sheet
Clear PETG sheet stands out from other transparent plastic materials due to a combination of properties that make it particularly well-suited for packaging, display, and fabrication applications.
High Optical Clarity: Clear PETG sheet offers excellent transparency and surface gloss, providing a clean, glass-like appearance that showcases packaged products effectively. The clarity is comparable to APET, but with significantly better impact performance.
Superior Impact Resistance: PETG is 5 to 10 times more impact resistant than standard acrylic (PMMA) and substantially tougher than APET. It does not shatter on impact — instead, it flexes and absorbs energy. This makes clear PETG sheet ideal for protective covers, machine guards, and packaging that must survive rough handling during transit.
No Stress Whitening: Unlike APET, which can develop white stress marks when folded or formed aggressively, PETG maintains its clarity even through deep draws and tight bends. This is a critical advantage for folding box and clamshell packaging, where crease lines must remain transparent.
Excellent Thermoformability: Clear PETG sheet forms easily on standard vacuum and pressure forming equipment at relatively low temperatures. It produces consistent, detailed molds with sharp definition and uniform wall thickness — making it the material of choice for complex packaging shapes.
Chemical Resistance: PETG resists a wide range of chemicals including oils, greases, dilute acids, and many household cleaning agents. This makes it suitable for industrial, medical, and food service environments.
Food Contact Compliant: Our clear PETG sheet is suitable for food packaging applications. Food-contact certification documentation (including FDA compliance) is available on request for qualifying orders.
Lightweight: At 1.27 g/cm³, PETG is lighter than PVC (1.4 g/cm³) and standard PET (1.35 g/cm³), which helps reduce material costs, shipping weight, and per-unit packaging weight.
Recyclable: PETG is a recyclable thermoplastic and can be reprocessed after use, supporting sustainable packaging goals.

Applications of Clear PETG Sheet
Clear PETG sheet is one of the most widely used transparent plastics in the packaging and display industries. Its combination of clarity, impact resistance, and thermoformability makes it suitable for applications where both visual appeal and physical durability are required.
Packaging
Clamshell and blister packaging (electronics, toys, hardware, consumer goods)
Food packaging trays, containers, and lids
Cosmetic and personal care product packaging
Pharmaceutical blister packs and medical device trays
Folding box windows and sleeves
High-frequency (HF) sealable packaging — PETG welds cleanly under HF sealing, unlike APET which typically requires a GAG sheet for this purpose
Displays & Signage
Point-of-purchase (POP) and point-of-sale (POS) displays
Retail shelf displays and product showcases
Exhibition and trade show panels
Menu boards and information displays
Protective screen covers and sneeze guards
Industrial & Fabrication
Machine guards and safety shields
CNC-routed components and prototypes
Vacuum-formed enclosures and housings
Printed overlays and graphic panels
Architectural glazing and interior partitions

Clear PETG Sheet vs. APET Sheet — How to Choose
Buyers often compare PETG and APET because both are transparent PET-family thermoplastics. Here is a practical comparison to help you select the right material:
| Property | Clear PETG Sheet | Clear APET Sheet |
| Impact Resistance | High — does not shatter, absorbs energy | Moderate — can crack under sharp impact |
| Stress Whitening | None — maintains clarity through bending and forming | Can develop white marks at fold lines |
| Thermoforming | Excellent — wider forming window, deeper draws possible | Good — but narrower window, risk of crystallization |
| Transparency | High (88–90%) | High (up to 89%) |
| HF Sealing | Compatible — seals well under high-frequency welding | Not directly compatible (use GAG instead) |
| Density | 1.27 g/cm³ (lighter) | 1.35 g/cm³ |
| Cost | Slightly higher than APET | Lower |
| Best For | Deep-draw packaging, folding boxes, protective covers, HF-sealed packaging | General blister packaging, food trays, cost-sensitive projects |
Rule of thumb: Choose PETG when the packaging will be handled roughly, requires deep forming, or needs HF sealing. Choose APET when cost is the primary concern and the forming depth is moderate.
Processing Clear PETG Sheet
Thermoforming
Clear PETG sheet thermoforms easily on standard vacuum and pressure forming equipment:
| Parameter | Guideline |
| Forming Temperature | 80°C – 120°C |
| Mold Temperature | 40°C – 65°C |
| Pre-drying | Recommended: 65°C for 2–4 hours (PETG is hygroscopic) |
| Forming Window | Wide — more forgiving than APET; less risk of crystallization or whitening |
| Deep Draw Capability | Excellent — suitable for complex shapes with tight radii |
Pre-drying is important for PETG. 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.
Cutting & Fabrication
| Method | Notes |
| Die Cutting | Suitable for high-volume production; clean edges |
| Laser Cutting | Produces smooth, polished edges |
| CNC Routing | Ideal for custom shapes and prototyping |
| Circular Saw | Use fine-tooth blades; maintain steady feed rate |
Printing & Decoration
| Method | Compatibility |
| UV Printing | Good adhesion; no primer typically required |
| Screen Printing | Compatible; produces vibrant results on clear surface |
| Hot Stamping | Compatible; for metallic logos and decorative elements |
| Vinyl Lamination | Compatible |
Bonding
Clear PETG sheet can be bonded using solvent cement (specific to PETG/PET), UV-cure adhesive, or cyanoacrylate. For structural bonds, solvent cement produces the strongest results. Proper surface preparation (clean, dry, dust-free) is essential for reliable bond strength.

Frequently Asked Questions
What is the difference between PETG sheet and APET sheet?
Both are transparent PET-family thermoplastics, but PETG is modified with glycol to improve impact resistance and formability. PETG does not stress-whiten when folded, offers a wider thermoforming window, and is compatible with high-frequency (HF) sealing. APET is slightly more rigid, less expensive, and sufficient for standard blister packaging with moderate forming depth.
Is clear PETG sheet food safe?
Yes. Our clear PETG sheet is suitable for direct food contact applications and is widely used for food packaging trays, clamshell containers, fruit and vegetable boxes, and bakery display covers. Food-contact compliance documentation is available on request.
What thicknesses and sizes are available?
We offer clear PETG sheet in thicknesses from 0.15mm to 6mm. Standard sheet sizes include 915 × 1220 mm and 1000 × 2000 mm. For thermoforming customers who require roll-form supply, widths from 300mm to 1400mm are available. Custom thicknesses, sizes, and cut-to-size services are available upon request.
Can clear PETG sheet be used for vacuum forming?
Yes. PETG is one of the most popular materials for vacuum forming due to its wide forming window, excellent detail reproduction, and resistance to stress whitening. It is suitable for both simple blister trays and complex deep-draw applications.
Does PETG yellow over time?
PETG has good resistance to UV-induced yellowing under normal indoor conditions. For extended outdoor exposure, UV-stabilized grades or protective coatings are recommended.
Can I get samples before placing an order?
Yes. We can provide samples in your required thickness for evaluation and testing. Contact our sales team to request sample sheets.
