Note: As different customers have different lamination equipment and cross-linking requirements, this process is only our recommendation, and customers can find the process that suits them best.


package

The inner diameter of the paper tube is 76 mm, and each roll is 100 meters. It is sealed with PE film. Each carton puts one roll, and each pallet contains 9 cartons.


Transportation and storage

Must be stored in a dry and cool constant temperature room

Temperature 0 ~ 30 ℃, humidity ≤60%;

The storage period of this product is 6 months from the production date


Application

1. Make sure that the EVA film is stored and used in a constant temperature and humidity room.

2. In order to avoid abnormal lamination of components due to static electricity, it is recommended to remove static electricity throughout the module.

3. The EVA film cut into sheets should be kept sealed to avoid pollution and moisture, and related facilities should be set up to avoid insect pollution.

4. It is recommended not to use each roll near the paper tube and the outermost circle.
