PET Battery Separator Film from Japan

Microporous polyester film used as separators in lithium-ion batteries. Despite its porosity, the non-cellular structure predominates, and the film is not reinforced or combined with other materials, ensuring electrolyte flow and safety.

Import Tips

• Document that the film is non-cellular despite its microporous structure, as this is key for classification

• Provide a technical datasheet to the CBSA showing the polyester composition and porosity

• Verify if the film is considered a part of a battery, which could affect classification
