Vacuum Metalized BOPP (VMBOPP)

Vacuum metalized BOPP film is a high-performance film obtained by upgrading BOPP through vacuum aluminum coating technology. It perfectly combines the high stiffness, excellent processability of the BOPP substrate, and the outstanding barrier properties (water resistance, oxygen resistance, light blocking) of the aluminum layer, as well as the magnificent metallic luster.


It is often used as an intermediate barrier layer or decorative outer layer in packaging structures. While providing comprehensive protection and an upscale appearance, it offers high cost-effectiveness and is one of the most widely used aluminum-coated films in the soft packaging fields, such as snacks and daily chemicals.

Key Difference: The core advantage of metalized BOPP lies in its excellent stiffness, low cost, and attractive appearance, making it highly suitable as the middle or outer layer of composite packaging. However, it cannot be heat-sealed on its own and must be combined with heat-sealing materials such as CPP or PE to form packaging bags. This is in stark contrast to metalized CPP that can be heat-sealed on its own and forms a complementary application.


Main Performance Features of VMBOPP Film

Excellent overall barrier properties
  • Extremely high water vapor barrier: far exceeding that of ordinary BOPP, it can effectively prevent the contents from getting damp or drying, significantly extending the shelf life.

  • Excellent oxygen barrier: it fills the gap of ordinary BOPP in oxygen barrier, effectively preventing the contents from oxidizing and deteriorating (such as spoilage of snacks, loss of flavor).

  • Complete light-blocking and high UV resistance: the aluminum layer can 100% block light, which is crucial for light-sensitive contents (such as oils, medicines).

Gorgeous appearance and decorative properties

It has a bright metallic luster, enhancing the packaging's grade and visual appeal, meeting the brand's demand for aesthetics.

Economy and environmental friendliness
  • Compared with the structure using aluminum foil, the amount of aluminum used is very little, the cost is lower, and the film is softer, less prone to pinholes due to bending.

  • It maintains the recyclable characteristic of BOPP film.

Maintaining the advantages of BOPP base material

Inherited the high stiffness (favorable for printing and composite processing), high strength and excellent printing adaptability of BOPP.
