Waterproof dependent material coating
The waterproof performance of label stickers mainly depends on the selection of their material and coating. The following are common waterproof label stickers and their characteristics:
Thin film adhesive label paper
This type of label paper is generally made of synthetic materials such as polyethylene, polypropylene, and polyvinyl chloride, which have good waterproof properties on their own. Thin film adhesive labels are not only waterproof, but also maintain dimensional stability and appearance in humid environments.
Synthetic paper (PP adhesive label paper)
This type of label paper is matte white in color, made of tough material, has good resistance to compression, and excellent moisture and water resistance. Its cost is lower than PET, suitable for heat transfer printing, and widely used in fields such as electronic components and daily chemical products.
PVC adhesive sticker
PVC label paper has good chemical corrosion resistance and tear resistance, but its temperature resistance and tensile strength are usually affected by temperature. Nevertheless, PVC label paper is still widely used in electronic, mechanical, battery, and outdoor posting scenarios.
Polyolefin (a mixture of PP and PE)
After machine uniaxial stretching treatment, this material has high tensile strength and tear resistance, while maintaining low opacity. It has both good softness and stiffness, performs well during labeling, and has good resistance to compression after labeling.
Specially treated water transfer printing stickers
For application scenarios with higher scratch resistance requirements, water transfer printing stickers printed with special scratch resistant materials can be used. After applying these stickers to the product, there is no need to spray additional varnish or perform other surface treatments. Simply bake them in an oven at 50-120 degrees Celsius for 30-60 minutes to achieve scratch resistance.
Other additional protective measures
In addition to selecting suitable substrates, the waterproof performance of the label can also be enhanced by coating or other forms of coating treatment on the surface of the label. For example, using UV coating or laminated film can further enhance the waterproof, corrosion-resistant, and scratch resistant capabilities of the label.
summarize
In summary, label stickers can achieve waterproof function mainly because they use specific waterproof materials as substrates and may be combined with additional surface treatment techniques. These designs ensure that label information remains clear, visible, and not easily damaged even under humid or flooded conditions.
