Single Margin Zinc Aluminium MPP Film With Heavy Edgy
Polypropylene plain film, 2 um–12 um, serves as the foundation for MPP films. 620mm is the typical width.
A coating machine in a high vacuum state melts, evaporates, and deposits high-purity zinc and aluminum on the base film, resulting in the formation of a metalized polypropylene film with a very thin metal layer on its surface.
Following a partial breakdown of the thin film dielectric, metallization has a self-healing action that causes it to automatically resume its electrical performance prior to the breakdown. Covering one or both of the metalized film’s edges or the center in order to create a blank insulating tape without evaporating metal is known as the margin, and its width is known as the margin.
Packing of Single Margin Al or Zn-Al MPP Film With Heavy Edgy
Film rolls are packed in plastic bags, vacuumed, and put into desiccant for heat sealing.
The 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 in wooden cases or reinforced cartons.
