Special black coating technology and the application of top graded glossy film eliminated the bottleneck of traditional technology caused by loosely laminating between the black and white films.

On the other hand,they are completely removable and none-glue remaining by means of black coating being applied between the white film and clear glue.

The innovation comprise the following chief traits:
pure white, super covering and extensive ability, anti-UV, forceful and straight, apt to absorbing, high printing resolution, bright and colorful.

The characteristics of excellent adherence to PVC film and perfect affinity are acclimatized to extreme environment.Totally resolved the problem of glue remains and unclearence resulted from marginal black glue extravasation.

1. A.Black film laminated with white PVC membrane,and coated with clear glue.This

technics give rise to following objections:
1.Under high and cold temperature,the black and white film will delaminate beacause of the substandard intensity of lamination.
2.The different shrinking rate of the white and black film gives cause for black and white interference.
B.Black glue was directly printed on the back of the film:
1.Black glue is apt to spread out by heat and remain on interface..
2.The black glue tends toward bubbling and peeling over time.

Focus perforated window film adopt black coating at PVC film back and apply superior clear adhesive.There are many remarkable advantages:

• ⑴Top grade film offers better ink-absorbing and extension ability.
  
• ⑵Black coating technology prevents the interference of black and white films.This technology won national patent in 2007.
  
• ⑶It's totally removable
