METAL-POLYMER TAPE Russian patent published in 2017 - IPC G06K19/02 B32B27/36 C23C14/20 

FIELD: physics.

SUBSTANCE: metal-polymer tape is a laminated tape consisting of polyethylene terephthalate films with an adhered light-absorbing layer applied. The said layer contains a mixture of aluminium powder as a filler and an antifriction filler at a weight ratio of 1:(0.08-0.12), with the following component ratio, %: thermally activated polymer of polyester type 63.0-67.0; mixture of aluminium powder and antifriction filler 26.1-36.7; pigment 0-9.8; oleic acid 0.3-0.4.

EFFECT: obtaining a film with high physical and mechanical properties, good perforatability with small punching forces and no light transmission and electrification of the tape, when rewinding.
