Cylindrical cell PET packaging sleeves are essential components in the battery industry, providing protection, insulation, and branding for cylindrical lithium-ion cells. These sleeves are made from polyethylene terephthalate (PET), a durable and heat-resistant material that ensures safety and longevity.
In this article, we will explore the manufacturing process, benefits, applications, and future trends of cylindrical cell PET packaging sleeves. We will also include visual aids (images and videos) to enhance understanding.
Cylindrical cell PET packaging sleeves are thin, flexible tubes designed to fit snugly around cylindrical battery cells. They serve multiple purposes:
- Protection: Shields against scratches, moisture, and short circuits.
- Insulation: Prevents electrical leakage and thermal issues.
- Branding: Allows manufacturers to print logos, specifications, and safety warnings.
The production of PET sleeves involves several key steps:
- PET film is chosen for its high tensile strength and thermal stability.
- Additional coatings may be applied for flame resistance.
- Digital or flexographic printing is used for branding.
- QR codes and safety labels can be incorporated.
- Precision cutting ensures a perfect fit.
- Heat sealing or ultrasonic welding secures the edges.
