Hello everyone
I am Jeff from COMAX.Why does some PVC tarpaulin fabric appear white line after folding?
Some PVC tarpaulin fabric appears white line after folding in the market. It is not suitable for looking and shortens the lifetime. It is because of the calcium percentage in the PVC formula. It is easier to see the white line if the manufacturer puts more calcium into the PVC formula. Of course, the cost will be lower if more calcium is in the PVC formula.
