What Are the Characteristics of PETG Shrink Film?

Jul. 17, 2023

PETG (Polyethylene Terephthalate Glycol) shrink film is a type of plastic film widely used for packaging applications. It offers several properties that make it a popular choice in various industries. Below are the key characteristics of PETG shrink film:


  • Transparency: PETG shrink film is highly transparent, allowing for excellent product visibility. This property is particularly advantageous for retail packaging, as it enables customers to see the product inside without opening the package. The clarity of PETG film helps enhance the visual appeal of packaged items.


  • High Shrinkage: PETG shrink film has a high shrinkage ratio, meaning it can tightly conform to the shape of the product when heated. Upon exposure to heat, PETG film shrinks evenly and uniformly, resulting in a snug, protective wrap around the item. This property ensures a professional and attractive appearance of the packaged product.


  • Excellent Printability: PETG shrink film is compatible with various printing methods, including flexographic, gravure, and digital printing. It allows for vibrant and high-quality graphics, branding elements, and product information to be printed directly on the film. The excellent printability of PETG film helps in creating eye-catching and informative packaging designs.

  • Good Tear Resistance: PETG shrink film exhibits good tear resistance, making it durable and less prone to damage during transportation or handling. The film's resistance to tearing ensures the integrity of the packaging, preventing accidental openings or product exposure. This property is particularly crucial for products with sharp edges or corners.


  • Impact Resistance: PETG shrink film offers good impact resistance, providing protection to the packaged items against minor bumps, knocks, or drops. The film's ability to absorb impacts helps prevent damage to the product and maintains its overall quality.


  • Moisture Resistance: PETG film has excellent moisture resistance properties, acting as a barrier against humidity and moisture ingress. This property helps protect the packaged items from moisture-related issues, such as spoilage, mold growth, or degradation. PETG shrink film is commonly used for packaging food, beverages, and other moisture-sensitive products.


  • Chemical Resistance: PETG shrink film is resistant to many chemicals, including oils, greases, solvents, and cleaning agents. This property ensures that the packaged products remain unaffected by external substances, maintaining their quality and integrity. PETG film is often utilized for packaging chemical products, cosmetics, and personal care items.

  • Environmental Friendliness: PETG shrink film is recyclable and can be easily identified in the recycling stream due to its resin code (PETG or #1). Recycling PETG film reduces the environmental impact and promotes sustainability in packaging. Additionally, PETG is considered safer than some other plastic films, as it does not contain bisphenol-A (BPA) or phthalates.


  • Versatility: PETG shrink film is versatile and can be used for packaging a wide range of products, including bottles, cans, boxes, and various consumer goods. Its ability to conform to irregular shapes and sizes makes it suitable for packaging items with unique geometries. PETG shrink film can be used in various industries, including food and beverages, cosmetics, pharmaceuticals, and household products.


  • Heat Resistance: PETG shrink film exhibits good heat resistance, allowing it to withstand the shrink-wrapping process without distorting or melting prematurely. PETG film requires relatively low temperatures to shrink, which makes it compatible with a wide range of packaging equipment.


In summary, PETG shrink film offers transparency, high shrinkage, excellent printability, tear resistance, impact resistance, moisture resistance, chemical resistance, environmental friendliness, versatility, and heat resistance. These properties make it an attractive choice for packaging applications, providing product protection, visual appeal, and sustainability.
