PETG Sheet — Clear Plastic Sheet Sizes, Thicknesses & Uses

PETG sheet is the dominant stock form for this material — the vast majority of PETG applications are flat-sheet based: displays, machine guards, signage panels, thermoformed trays, and food-contact covers. PETG sheet combines optical clarity (>90% light transmission), impact toughness (3–4× acrylic), easy thermoforming, and FDA food-contact compliance, making it the workhorse clear plastic for fabricators and thermoformers.

At a glance:

  • Standard sizes: 48" × 96" (primary); 24" × 48"; 36" × 48"
  • Thickness range: 0.030" to 0.500" standard; thicker gauges available
  • Thickness tolerance: ±0.003" (thin) to ±0.015" (thick)
  • Both sides protected with masking film (paper or PE); remove before use
  • FDA 21 CFR 177.1630 — both food-contact and non-contact applications
  • Not suitable for outdoor use in standard grade — specify UV-stabilized for outdoor

Custom Cut-to-Size

Ready Plastics can supply PETG sheet cut to specific dimensions from stock. Custom cut pieces are typically sawn or laser cut from standard stock sheets. Minimum order quantities apply for non-standard sizes.

Selecting Thickness for Your Application

Display and Sign Fabrication

  • Ticket holders, brochure stands, small displays: 0.060"–0.093" — flexible enough to snap into slots, rigid enough for vertical use
  • Large display panels, product covers: 0.125"–0.187" — rigid, stands freestanding, routes cleanly
  • Heavy display bases and frames: 0.250" — structural rigidity for display frames

Machine Guards

  • Light splash shields: 0.125" — adequate for low-energy splash or incidental contact
  • Standard machine guards: 0.187"–0.250" — protects against typical chip and debris impact
  • Heavy-duty guards: 0.375"–0.500" — for applications with more significant impact risk

For guards subject to high-energy impact, polycarbonate is the appropriate specification rather than PETG.

Thermoformed Packaging

  • Clamshells and blister packs: 0.030"–0.093" — standard food packaging gauge
  • Reusable trays and containers: 0.093"–0.125" — thermoformed to depth of 0.5"–2.0"

PETG Sheet vs Competing Clear Sheet Materials

Handling, Cutting, and Forming PETG Sheet

Masking and Handling

PETG sheet ships with paper or PE masking on both faces to protect the optical surfaces. Keep masking on during storage, transport, and until final fabrication — PETG is not as scratch-resistant as acrylic, and exposed sheet will accumulate fine scratches from dust and handling.

Remove masking before thermoforming — leaving masking on during oven heating causes adhesive transfer to the sheet surface.

Cutting

  • Score and snap: Valid for thicknesses ≤0.125" with a sharp scoring knife
  • Table saw / panel saw: TCG carbide blade, 80–100 teeth, 3,000–4,000 RPM
  • CNC router: O-flute or 2-flute carbide, 18,000–22,000 RPM, climb routing for clean edge
  • Laser cutting: CO₂ laser produces clean cuts with slight polished edges; settings vary by machine

Thermoforming

Oven temperature: 280–340°F. Pre-dry at 140–160°F for 2–4 hours to prevent blistering. Full thermoforming parameters are in the PETG machining guide.
