Battery Packaging: The Advantages of PETG Film

PETG (Polyethylene Terephthalate Glycol) battery film is an innovative material in the realm of battery Packaging that offers numerous advantages over traditional battery packing solutions. PETG film is a non-crystalline copolyester which means it does not have a crystallization temperature, making it easy to mold and bond without the risk of albinism-a flaw commonly associated with PET materials.

This thermoplastic polyester provides significant chemical resistance, durability, and excellent formability, making it ideal for manufacturing applications where these properties are essential. The addition of glycol at the molecular level enhances these characteristics, differentiating PETG from its PET counterpart.

Notably, PETG film exhibits good thermoformability at low temperatures and offers cost-effectiveness for applications that do not demand high-performance films. It is also recognized for its high rigidity, which is particularly beneficial when packaging batteries that require a sturdy, yet flexible containment solution3.

For battery packaging specifically, PETg battery films are available that can shrink between 30%-80%, depending on the requirements. This feature ensures a snug fit around batteries, providing a protective layer that can conform to various shapes and sizes. These films come in a range of thicknesses, typically from 0.02 mm to 0.5 mm, and are Transparent, allowing for the easy identification of the battery within. The width of the films can range from 500 mm to 1150 mm, catering to different battery dimensions.

In summary, PETG battery film is a versatile, durable, and cost-effective material suitable for the protective packaging of batteries. It brings enhanced performance characteristics such as chemical resistance, rigidity, and thermoformability, making it an excellent choice for battery manufacturers looking for reliable packing materials.
