Common Storage Precautions for Self-Adhesive Materials
The rainy season is characterized by high humidity, making moisture control crucial when using self-adhesive materials. Key precautions include:
Storage:
-
- Keep the original packaging intact until the materials are ready for use.
-
- If self-adhesive materials are temporarily unused after opening or need to be returned to storage, they should be promptly repackaged to prevent moisture absorption.
-
- Dehumidification measures should be implemented in storage and processing areas.
-
- Semi-finished and finished products should be promptly packaged, with particular attention to sealing and moisture-proofing.
Label Application:
-
- Common issues during label application in rainy seasons include label lifting, peeling, and bubbling, especially on corrugated cartons.
-
- Avoid opening the packaging of labels before application to prevent moisture-related deformation.
-
- Ensure that the surfaces to be labeled, such as cartons, are kept dry to avoid warping, wrinkling, or bubbling.
-
- Newly made corrugated cartons should be allowed to acclimate to the environment’s humidity before labeling.
-
- Align the grain direction of the labels with that of the corrugated cartons to minimize the risk of wrinkling or lifting after application.
-
- Apply adequate pressure during labeling, especially at the edges, to ensure proper adhesion.
-
- After labeling, store the labeled products in a low-humidity, enclosed space until the adhesive sets before moving them to outdoor storage or transportation.
