Name：coated overlay films(strong type)
Item NO.：PVC-B-QU
Sphere of Application:
B-QU coated overlay films are mostly used for high-grade cards such as bank cards, IC cards, social security cards, RF cards, etc.
Chemical Specifications:
Gravity:（20/4℃）1.25g/cm3
chloride content 56～58％
Products of low molecular are easy to solution in solvents like ketones, esters and chlorinated hydrocarbon, etc, while products of high molecular are difficult.
acid and alkali resistance, wearing resistance, electrical insulating property, fire resistance, can be rope soled, water resistance, resist heat, innocuity, high initial stick force, color inhibition
Physical Specifications:
Gravity of rigid pvc: 1.38-1.43 g/cm3
High Mechanical Strength
Good chemical stability
Manufacture Method:
1,Put printing core and two overlay together, then put into the laminator, the temperature is determined as per the instruction of the machine , Pls be noticed that all glue sides of both pvc sheets and overlay are put inward.
2,The lamination usually lasts 10-15minutes ,The pressure is 6-8Mpa, The temperature is 120-140℃
3,Cut the card
Size and Packing:
Thickness: 0.04-0.2mm
Width: ≤1300mm
Length: ≤2000mm
Packing with PE films, in rolls or sheets, wooden pallet or cardboard boxes
The obility of fellow products:
high initial stick force(reaches to 7-8N/CM)
The rustiness of B-QU are slower than that of B-PU
color inhibition, not easy to change shape while lamination, easy to use with a smooth surface
