Application Cases of Non-Transfer Tamper Evident Label SK-88

In a South American country, the non-transfer type confidential tape SK-88 was used in election activities. Our customer die-cut SK-88 according to the government's 

specified specifications and applied it to the circuit board of the voting machine before the general election to prevent any malpractice during the election process. 

After the election was completed, the non-transfer tamper evident labels were removed. There was no ink or adhesive residue on the voting machine.


Currently, the non-transfer type tamper evident label SK-88 is widely used in towing teams of traffic police in various cities and counties in Taiwan. When towing illegally 

parked vehicles, traffic police apply Seal King’s non-transfer tamper evident labels to the car doors. When the owners reclaim their cars and tears off the labels, there will 

be no ink or adhesive residue on the vehicle body.
