PETG Film: An Essential Component for Cylindrical Lithium Battery Packaging Labels

PETG (Polyethylene Terephthalate Glycol) film serves as a critical element in the production of labels for cylindrical lithium batteries, forming an integral part of the packaging process. Typically, battery packaging labels consist of six layers, each serving a specific function:

1.Protective UV Varnish Layer: This layer provides protection against ultraviolet (UV) radiation, safeguarding the integrity and appearance of the label.

2.Ink Layer: The ink layer contains the printed design, information, and branding elements on the label, ensuring clarity and durability.

3.PET Shrink Film: PETG film is commonly utilized as the shrink film layer, allowing the label to conform tightly to the cylindrical shape of the battery during the heat shrinking process, providing a snug fit and professional appearance.

4.Aluminum Layer: Positioned to enhance the barrier properties of the label, the aluminum layer acts as a barrier against moisture, gases, and external contaminants, preserving the quality and longevity of the battery.

5.Adhesive Layer: This layer serves as the bonding agent, facilitating the attachment of the label to the battery surface securely.

6.Release Liner: The release liner is the bottommost layer of the label, providing a non-stick surface to prevent the adhesive from prematurely adhering to other surfaces before application.

In the production of labels for cylindrical lithium batteries, the PETG film's versatility, durability, and shrink properties make it an optimal choice for ensuring a seamless labeling process. Its ability to conform to the unique shape of cylindrical batteries, coupled with its excellent printability and adhesive compatibility, enables manufacturers to achieve high-quality, visually appealing labels that meet stringent industry standards.

As the demand for lithium batteries continues to grow across various industries, including consumer electronics, electric vehicles, and energy storage systems, the importance of PETG film in battery labeling applications remains paramount. Manufacturers and suppliers are continually innovating and refining their processes to meet the evolving needs of the market, driving efficiency, sustainability, and performance in battery packaging solutions.
