Environmental Conditions
Printing paper should be stored in a dry, well-ventilated, and temperature-controlled environment, avoiding high temperatures, humidity, and direct sunlight. High temperatures can cause the adhesive layer to soften, flow, or age prematurely; humid environments may affect paper flatness and print quality; and prolonged exposure to sunlight can cause the surface layer to fade or become brittle, thus affecting the label's lifespan.
Storage and Packaging Protection
Unused self-adhesive printing paper should be kept in its original packaging, maintaining the flatness of rolls or flat sheets to prevent wrinkles, bending, or dents. For roll labels, they should be placed vertically or horizontally to avoid prolonged stress that could cause curling or deformation; for flat labels, they should be stacked neatly to avoid pressure that could cause labels to lift or stick together.
Regular Inspection and Usage Order
Self-adhesive printing paper stored for extended periods should be regularly inspected for the condition of the adhesive layer and backing paper to ensure there is no adhesive failure or moisture-induced deformation. When using, print paper that has been stored for a longer period should be used first, following the first-in, first-out principle to ensure optimal label performance during printing and application. At the same time, avoid storing it with corrosive substances or substances with strong odors to prevent affecting the adhesion of the adhesive layer or the quality of the surface layer.
