Rainy Season Storage, Processing, and Usage Precautions for Self-Adhesive Label Materials

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.
