The best option to choose for labels that need to be written on would be the 60lb Uncoated Label. This material can be written on with pens, pencils, markers, and speciality writing devices without the ink smudging risk. 60lb Gloss and the Vinyl options can be written on, however only with a Sharpie-style marker and certain pens. If the ink is too watery, it will need to dry before being handled or else it could smudge or smear. Gloss or silk lamination is also compatible with markers and certain pens, but the ink might need to dry. As UV coating is oil-based, it will not work with any type of writing implement and should be avoided if the labels need to be written on.
