Clear PETG Sheets – .020", .030" & .040"

Crystal-clear, impact-resistant plastic sheets for thermoforming, prototyping, protective covers, displays, and custom fabrication.

Bring your ideas to life with Clear PETG Sheets. PETG (Polyethylene Terephthalate Glycol-Modified) is a versatile thermoplastic that combines excellent optical clarity with toughness, flexibility, and easy fabrication.

Popular for vacuum forming, thermoforming, product prototyping, and clear protective components, PETG offers greater impact resistance than standard acrylic and can be formed at relatively low temperatures. Its smooth, glossy surface makes it particularly useful for transparent housings, display components, packaging prototypes, and detailed models.

Available in .020", .030", and .040" thicknesses, Clear PETG is ideal for designers, engineering students, makerspaces, and fabricators who need lightweight, transparent material in convenient, project-ready sizes.

Thermoforming & Fabrication Tips

PETG is popular for thermoforming because it can be heated and shaped into detailed transparent components while retaining good clarity.

For best results:

  • Heat evenly and avoid overheating, which can cause bubbles, distortion, or discoloration.

  • Use smooth molds and appropriate draft angles for easier part removal.

  • Allow formed parts to cool before removing them from the mold.

  • Account for material thinning in deep or complex shapes.

  • Use sharp tools and appropriate cutting speeds to minimize heat buildup.

Laser Cutting: Not recommended for general use. PETG can melt, discolor, and produce potentially hazardous fumes during laser processing. Use conventional cutting or CNC methods unless your equipment manufacturer and facility safety procedures specifically authorize laser processing.

Pro Tip

Choose the thickness based on the detail, flexibility, and rigidity your project requires.

  • .020" (0.51mm): Architectural glazing, miniature components, lightweight models, and shallow formed parts.

  • .030" (0.76mm): Packaging prototypes, detailed vacuum-formed shapes, and transparent model components.

  • .040" (1.02mm): More substantial covers, enclosures, display components, and formed prototypes.

For transparent thermoformed parts, start with a clean mold and avoid overheating to help preserve optical clarity.

FAQs

What is PETG?

PETG is a glycol-modified polyester thermoplastic known for its clarity, impact resistance, and ease of fabrication. It is widely used for thermoforming, prototyping, packaging, and displays.

Is PETG more impact resistant than acrylic?

Yes. PETG generally offers greater impact resistance and toughness than standard acrylic, making it useful for transparent components that may experience handling or mechanical stress.

Can PETG be vacuum formed?

Yes. PETG is well suited for vacuum forming and thermoforming and can be shaped into detailed three-dimensional components at relatively low forming temperatures.

Can PETG be cut with a knife?

Thin PETG sheets can be cut with appropriate knives, shears, or other cutting tools. The best method depends on thickness, part geometry, and the desired edge quality.

Can PETG be laser cut?

Laser cutting is not recommended for general use because PETG can melt, discolor, and release potentially hazardous fumes.

Is PETG suitable for outdoor use?

Standard PETG has limited UV resistance and is primarily recommended for indoor applications. Extended sunlight exposure may cause yellowing or deterioration.

Is PETG food safe?

Some PETG grades are approved for certain food-contact applications, but suitability depends on the specific resin grade, manufacturing process, and applicable regulations. Do not assume these sheets are food-contact certified.
