Guide to Buying PETG Shrink Film

Mar. 10, 2023

PETG (Polyethylene Terephthalate Glycol) shrink film is a type of plastic shrink film used for packaging and labeling applications. It is a popular choice among businesses because of its high clarity, durability, and versatility. PETG shrink film is used in various industries, including food and beverage, pharmaceuticals, cosmetics, and consumer goods.


If you are planning to buy PETG shrink film, here are some factors to consider:



The gauge of the PETG shrink film refers to its thickness. The thicker the film, the more durable and stronger it is. PETG shrink film typically comes in gauges ranging from 40 to 120. The gauge you choose will depend on the product you are packaging and the level of protection it needs.


For example, a heavier product will require a thicker gauge film for better protection. On the other hand, a lightweight product can use a thinner gauge film to save on costs. It is important to note that the gauge also affects the shrink rate and clarity of the film. Thicker films tend to shrink slower but offer better clarity, while thinner films shrink faster but may not be as clear.

Shrink Rate

The shrink rate of PETG shrink film refers to the amount of shrinkage that occurs when heat is applied. PETG shrink film typically has a shrink rate of 70-78%. The shrink rate is important to consider as it affects the fit and appearance of the package. If the shrink rate is too low, the film may not conform well to the product, resulting in wrinkles or gaps. If the shrink rate is too high, the film may over-shrink and distort the product.



PETG shrink film is known for its high clarity, which is important for packaging and labeling applications. The clarity of the film is affected by the gauge, as well as the manufacturing process. High-quality PETG shrink film is manufactured using advanced extrusion techniques that result in a film with excellent clarity and gloss.



PETG shrink film is strong and durable, which is important for protecting products during shipping and handling. The strength of the film is affected by the gauge and the manufacturing process. Thicker films are generally stronger but may be more expensive. PETG shrink film should also be puncture-resistant to prevent damage to the product.

Roll Size

PETG shrink film is sold in rolls, and the size of the roll is an important factor to consider. The roll size will depend on the amount of film you need for your packaging or labeling application. If you are packaging a large volume of products, you may need a larger roll size to avoid frequent changeovers. It is also important to consider the width of the film, as it affects the amount of film needed to wrap each product.



When buying PETG shrink film, it is important to choose a reputable supplier. A good supplier will provide high-quality film at a competitive price, and offer excellent customer service. Look for a supplier that has a good reputation in the industry, and has experience working with businesses in your industry. Ask for references and samples of their film before making a purchase.



The cost of PETG shrink film is an important factor to consider, but should not be the only factor. While it is important to stay within your budget, choosing a lower quality film may result in higher costs in the long run. Poor quality film may require more film to be used for each package, or may result in damaged products that need to be replaced.


In conclusion, PETG shrink film is a popular choice for packaging and labeling applications due to its clarity, strength, and versatility.
