MPP film is a type of plastic film that is used for various applications including packaging, printing, and laminating. It is a multi-purpose film that is made from polypropylene, which is a strong and flexible material.
The margin on both sides of an MPP film refers to the space or distance between the edge of the film and the printed or laminated material. This margin is usually added to allow for proper handling, cutting, and sealing of the film during the manufacturing process. It also helps to prevent any damage to the printed or laminated material during transport or storage.
The size of the margin on both sides of 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.

Film rolls are packed in plastic bags, vacuumed and put into desiccant for heat sealing.
he Bags are marked with type labels, mark thickness width, free margin width and resistance.
The bags are packed in carton cases.
The cartons are wrapped by wooden cases or reinforced carton.
