PAPERBOARD FOR USE IN WATER RESISTANT PACKAGING |
摘要 |
A method of producing paperboard and cartons made therefrom is described incorporating a waterproof or water resistant coating applied to the interior of the carton except for areas intended for gluing. A coating material (122) is applied to the surface of an applicator roll (110), and a portion of the coating material is then removed from the roll. Contact between a paperboard web (150) and the roll transfers coating material to the web, creating a coated surface except for an uncoated stripe (237). A carton blank (300) may be formed from the coated web with the uncoated portion of the carton blank cut from the uncoated stripe.
