PETG shrink film is a premium heat-shrinkable polyester film widely used for producing high-clarity shrink sleeve labels. Known for its smooth shrink behavior and excellent transparency, PETG shrink film is ideal for complex container shapes and high-end packaging applications where visual quality and consistency are critical.
PETG shrink film (also known as PET-G heat shrinkable film) is a co-extruded, glycol-modified polyester known for high clarity, controlled TD shrinkage up to 75–80%, excellent heat resistance, and environmental friendliness. It starts shrinking around 70–80 °C, offering tight conformability around complex shapes with minimal MD shrink (“smile effect” control).
Ideal for beverage sleeve labels, cosmetics, food packaging, and retail security wraps, PETG excels where both visual appeal and functional performance matter.
As a professional shrink label film supplier, we provide PETG shrink film rolls engineered for stable performance on high-speed sleeve labeling lines.
Our PETG Shrink Sleeves Film:
| • Clear PETG Shrink Film | • PETG Bidirectional Shrink Film | • Clear PETG Shrink Tubing Roll | |
 |  |  |  |
Thickness: 30–60 µm (also available in matte, transparent, and white variants)
Shrinkage: Up to 70–80% TD (transparent grades)
Shrink Temp: 70–80 °C start, full shrink under ~95 °C for most grades
Compatible with rotogravure, flexo, and UV-offset printing—achieves clear, vibrant prints for labels and sleeves
Matte finish options available for "paper-like" feel and handling (e.g., Transcendia 7M)
PETG shrink film typically provides a transverse direction (TD) shrink ratio of 60%–75%, with minimal machine direction (MD) shrink. This high, uniform shrink performance makes PETG ideal for complex, contoured containers used in premium shrink sleeve labeling applications.
Recommended PETG Shrinkage Rates for Different Applications:
Standard Beverage Bottles: TD 60%–65%
Conical/Irregularly Shaped Bottles: TD 65%–70%
High-Drop Bottle Shapes (Shoulder + Waist Variations): TD 70%–75%
Different colors of PETG shrink film usually have the same rated shrink ratio, but actual shrink performance may vary slightly due to pigment content and heat absorption, especially between dark and light colors.
PETG shrink film provides exceptional clarity and gloss, enabling vibrant colors, sharp graphics, and a high-end shelf appearance.
With consistent transverse direction (TD) shrink behavior, PETG film minimizes distortion on complex container shapes.
Compatible with gravure, flexographic, and digital printing, PETG shrink film ensures strong ink adhesion and high-resolution image reproduction.
PETG film resists moisture, oils, and handling abrasion, maintaining label integrity throughout filling, transportation, and retail display.
| Feature | PETG Shrink Film | PVC Shrink Film | POF Shrink Film |
|---|---|---|---|
| Clarity | Exceptional transparency & gloss | Moderate clarity, may yellow | Excellent clarity, durable |
| Shrink Rate | Controlled, up to ~80% at moderate heat | Lower shrink, may not conform | Fast shrink, but lower clarity |
| Heat Resistance | High | Moderate | Very good |
| Toxicity | Non-toxic, recyclable | Emits chlorine gas, harmful | Food-safe, recyclable |
PETG is more eco-friendly than PVC (no chlorine release, recyclable) and offers better dimensional control than PVC with more aesthetic clarity for high-end packaging applications.
PETG (Polyethylene Terephthalate Glycol-modified) shrink film is a heat-activated shrink sleeve material that contracts uniformly when exposed to controlled heat through steam or hot air tunnels. It allows full-body labeling with precise conformity to curves, tapers, and irregular container geometries.
PETG shrink film is commonly used in:
Beverage bottles (water, juice, energy drinks, spirits)
Cosmetic and personal care packaging
Nutraceutical and pharmaceutical containers
Premium food and specialty product packaging
It is especially suitable for irregular, contoured, or tapered bottles requiring full-body decoration.
Brand visibility: Superior transparency and gloss deliver premium shelf impact for cosmetics, beverages, and electronics.
Smooth shrink behavior: Controlled shrink avoids distortions, particularly important for tapered/container wraps.
Sustainability: Recyclable, non-toxic—aligns with green packaging policies.
Printing flexibility: Supports various printing technologies without compromising shrink performance.
Complex geometries: Shrink film conforms tightly even on intricate shapes (e.g., curved bottles, jars).
Typical MOQ: 1,000 kg per model, with sample service available upon request
Thickness Range: 30–60 µm; also available in 30/35/40/45/50/60 µm, plus matte or white variants
Roll Width: Typically 300–2000 mm; custom widths offered
Printing Surface: Glossy and matte surfaces; corona treated for ink adhesion.
Downloadable Technical Data Sheet (TDS) and Shrink Curve.
Certifications: Food-safe grades, RoHS, recyclable compliance.
Q1: What shrink ratio can PETG shrink film achieve?
A: PETG can deliver up to 75–80% TD shrinkage under ~95 °C, ideal for sleeve and cap wrapping.
Q2: Can PETG film print with UV inks?
A: Yes — PETG supports rotogravure, flexo, and UV offset, producing vivid graphics.
Q3: Is PETG recyclable? How does it compare to PVC?
A: PETG is fully recyclable and non-toxic. PVC, by contrast, may emit harmful gases and is more difficult to recycle.
