What Is the PETG Shrink Film?

Jun. 28, 2024

PETG shrink film, also known as Polyethylene Terephthalate Glycol shrink film, is a versatile and durable material widely used in packaging and labeling applications. It offers excellent shrinkage properties, clarity, and strength, making it a preferred choice for various industries. This guide provides an in-depth look at PETG shrink film, its benefits, applications, and how it compares to other shrink films.

1. Understanding PETG Shrink Film

PETG shrink film is a thermoplastic polymer that combines the benefits of PET (Polyethylene Terephthalate) with the added flexibility and impact resistance of glycol modification. This modification prevents the film from crystallizing and becoming brittle during the shrink process, allowing for uniform shrinkage and a smooth, high-quality finish.

2. Key Benefits of PETG Shrink Film

PETG shrink film offers several advantages that make it ideal for packaging and labeling:

High Clarity and Gloss

PETG shrink film provides excellent transparency and gloss, enhancing the visual appeal of products and making labels stand out on store shelves.

Strong Shrinkage

The film can shrink up to 78% in the transverse direction, ensuring a tight, form-fitting wrap around various container shapes and sizes.

Durability and Strength

It is highly resistant to tearing and puncturing, providing reliable protection for packaged products.


PETG is recyclable and considered more environmentally friendly compared to other shrink films like PVC.

Compatibility with Printing

The film is compatible with various printing techniques, allowing for high-quality graphics and vibrant colors.

3. Common Applications of PETG Shrink Film

PETG shrink film is used in a variety of applications across different industries:

Labels and Sleeves

It is widely used for shrink labels and sleeves on beverage bottles, food containers, cosmetics, and pharmaceuticals. The film conforms tightly to the contours of the containers, providing 360-degree coverage for branding and information.

Tamper-Evident Seals

PETG shrink film is used to create tamper-evident seals for products, ensuring the integrity and safety of the contents.

Multi-Pack Bundling

It is effective for bundling multiple products together, such as promotional packs and multi-unit sales, keeping the items securely in place during transportation and handling.

4. How PETG Shrink Film Compares to Other Shrink Films

There are several types of shrink films available, each with its own set of characteristics. Here’s how PETG shrink film compares to other common shrink films:

PVC (Polyvinyl Chloride) Shrink Film

- **Pros**: PVC shrink film is cost-effective and offers good clarity.

- **Cons**: It has lower shrinkage rates compared to PETG and is less environmentally friendly due to the release of harmful chemicals during production and disposal.

OPS (Oriented Polystyrene) Shrink Film

- **Pros**: OPS shrink film provides excellent clarity and high shrinkage rates.

- **Cons**: It is more brittle and prone to tearing compared to PETG, and is less environmentally friendly.

PLA (Polylactic Acid) Shrink Film

- **Pros**: PLA shrink film is biodegradable and compostable, making it an eco-friendly option.

- **Cons**: It has lower durability and strength compared to PETG, and may not provide the same level of clarity.

5. Processing and Handling of PETG Shrink Film

Proper processing and handling are essential to achieve optimal results with PETG shrink film:

Shrink Temperature

The recommended shrink temperature for PETG shrink film is between 180°C and 200°C. Maintaining the correct temperature ensures uniform shrinkage and a smooth finish.

Storage Conditions

Store the film in a cool, dry place away from direct sunlight and heat sources to maintain its quality and performance.

Compatibility with Equipment

Ensure that your shrink tunnel or heat gun is compatible with PETG shrink film and can provide consistent heat distribution.
