The seal labels may be made of paper, plastic films (such as PVC, PET, etc.), fabric, etc. Different materials have different characteristics. For example, the paper-based seal stickers have a soft texture and are convenient for writing. Those made of plastic films have better waterproof and moisture-proof properties. Those made of fabric are more durable and have some flexibility. Regarding the adhesive, high-quality seal stickers usually use adhesives with strong adhesion, long-lasting, and not prone to residue, ensuring that the items can be firmly sealed and will not damage the surface of the object when it needs to be removed.
The main emphasis is on its sealing performance. For instance, good stickiness can ensure that the sealed items will not accidentally open during transportation and storage, thereby protecting the contents. Additionally, some seal labels may have special functions, such as waterproofing, moisture-proofing, and anti-tearing. For example, seal labels used for food packaging may need to have waterproof and moisture-proof functions to extend the shelf life of food; while seal labels used for important documents or receipts may have anti-tearing designs to ensure the integrity and security of the documents.
Cleaning the Surface: Before attaching the seal label, make sure the surface to be labeled is free of dust, water stains or oil stains. Otherwise, seal label will affect the stickiness of the label. You can wipe the surface with a clean soft cloth to keep it dry and clean.
Removing the Backing: Carefully start from one corner of the seal label and slowly peel off the backing paper. Be careful not to cause the label to curl or stick together, and ensure that the backing is fully exposed.
Precise Positioning: Place the seal label accurately at the position to be sealed, ensuring the position is correct and the pattern and text are oriented properly. If the position is off, adjust it promptly to avoid difficulty in moving the seal label after it is fully adhered.
Pressing for Adhesion: Use your fingers or a scraper, etc., to press from the center of the label to the edge gradually, expelling air and ensuring the label is fully adhered to the surface to prevent bubbles and wrinkles.
Checking and Reinforcing: After the sealing is completed, carefully check if the edges of the seal label are firmly attached. For the edge part, you can press again to reinforce it to ensure the sealing effect.
Printing: Offset, Gravure, Flexographic, Digital and other processes cater to different material and design requirements of seal labels. Digital printing is suitable for small-batch customization, while Gravure is conducive to large-scale high-quality production.
Die-cutting: Use die-cutting knives to cut seal labels into the desired shapes and sizes. High-precision die-cutting ensures the quality of labels with special shapes.
Gluing: Uniformly apply adhesive through roller coating or scraping coating methods. The amount and method of gluing affect the stickiness of seal labels.
Materials: Seal labels are made from degradable (such as polylactic acid), renewable (bamboo pulp paper) or recycled materials.
Production: Use environmentally friendly inks and adhesives to reduce pollutant emissions and optimize processes to enhance energy efficiency.
Recycling: Mark with recycling symbols, and enterprises participate in recycling projects to promote the recycling of seal labels.
