Ordinary wrapping or packing paper should not automatically be substituted for kraft paper intended for laminating work. A suitable backing must feed consistently, remain stable under operating pressure, and perform correctly around exposed adhesive. Some applications require machine-glazed kraft paper, while others need a coated release paper that prevents adhesive from bonding to its surface. General packing paper may wrinkle, tear, shed fibres, or stick to the adhesive. Confirm the required backing construction in the laminator or adhesive-film instructions. Process a short test section before a production run and stop if the paper tracks unevenly, bonds to the adhesive, leaves residue, or begins wrapping around the rollers.
