Stock Laser Labels have only two different "tack/stickiness" and the word your looking for is adhesive, either permanent or removable and I have never heard of any label manufacturer who wont provide free samples upon request, it’s an industry standard.
My point was that Integrated labels cost is becoming more affordable, compared to that of laser label sheets (price per 1,000 sheets) and the product is more versatile in terms that is can be used as a picking note, packing slip, despatch note and invoice, in my opinion!
