Menus Place Mats 11 x 17-inch Paper Sheets Arts &amp; Crafts Tabloid Size Sheets Signs Many of todays pouch laminators have silicone rubber rollers that do not require the use of laminating carriers; however, we do recommend the use of carriers to extend the life of the rollers in your machine and improve lamination results. <span class="a-text-bold">Heres why:</span> During the lamination process, all laminating pouches generate a small amount of adhesive squeeze out past the edge of the pouch which can accumulate on your machines rollers. That excess adhesive dries, cracks and eventually ruins the laminator rollers. Carriers protect the rollers from excess adhesive and extend the life of your laminator. <span class="a-text-bold">Also,</span> This adhesive will likely show as very thin lines on additional pouches run through afterward. It can be removed with rubbing alcohol; however, using a carrier catches that excess adhesive without leaving traces on your next pouch. <span class="a-text-bold">And,</span> Carriers protect the exterior of your pouch from scratching during the laminating process, which may occur when running through the cooling plates at the back of your laminator (if equipped). For customers with adjustable temperature laminators who are trying a new brand, we recommend lowering the temperature approximately 25 degrees F for the first sheet or two. Users can always re-run laminate that was not run hot enough and seems foggy, but you cannot fix blister bubbles caused by running too hot the first time. Laminators with speed control can achieve a cooler result by trying a faster speed at first. Then, slow the speed as necessary to achieve perfect laminating results. Generally, setting the perfect temperature and speed will be done just once for each thickness of laminating pouch; however, temperature requirements may also be affected by large dark solid colors which draw more heat. Sheets should not be laminated until at least 24 hours after being printed. This is especially true for laser and digital output. Allowing printed sheets to be open to air for extended time before laminating will increase adhesive grip. <span class="a-text-bold">DO NOT ROLL UP laminated prints until adhesive has cured completely</span>. Customers who plan to trim sheets after laminating (<span class="a-text-bold">flush or multiple cards per pouch</span>) should wait at least 24 hours to allow adhesive to cure. Curing will produce a cleaner and more professional cut. Industry standard specification for 3 mil laminating pouches is 3 mil on each flap for a total of 6 mils added to your paper and 1 mil equals 1/1000th of an inch and 25 microns metric. The lamination industry calls these laminating pouches yet they are sealed on only one edge, like a file folder.
