Al MPP Film With Center Margin

An MPP film with a center margin refers to a film that has a margin or space between the printed or laminated material and the edge of the film in the center of the film. This margin is usually added to allow for proper handling, cutting, and sealing of the film during the manufacturing process. It can also help to prevent any damage to the printed or laminated material during transport or storage.

The size of the center margin on an MPP film can vary depending on the specific application and the requirements of the end-use product. It is important to consider the margin size when selecting an MPP film for a particular project to ensure that it meets all the necessary specifications.

In addition to the center margin, MPP films can also have margins on both sides or only on one side. The type of margin needed will depend on the specific requirements of the project and the desired end result.
