What are the differences between PET and PE liners?

PET and PE liners are two different types of liners commonly used in adhesive tapes and labels.

PET liners are made of polyester films, which are known for their high tensile strength, dimensional stability, and resistance to moisture and chemicals. PET liners are commonly used in applications where a high level of precision is required, such as in the electronics and medical industries. They are also suitable for use with high-speed die-cutting equipment.

On the other hand, PE liners are made of polyethylene films, known for their flexibility, cost performance, and good release properties. PE liners are commonly used in applications where a low level of precision is required, such as in the packaging and labeling industries. They are also suitable for use with a wide range of adhesive formulations.

In summary, the main differences between PET liners and PE liners are their material properties and their suitability for different applications. PET liners are more robust and more precise, while PE liners are more flexible and cost-effective.
