What is the difference between hot melt adhesive and water-based adhesive used for label paper

There are significant differences between hot glue and water-based glue used in label paper in multiple aspects. The following is a detailed comparison:

Hot glue adhesive

High viscosity but low viscosity

Adhesive properties: high viscosity, suitable for long-term adhesive labels, not suitable for repeated pasting. Low viscosity, suitable for temporary labels or labels that need to be frequently removed, can be easily removed without leaving any traces

Strong water resistance, not easily affected by moisture or chemical corrosion, difficult to maintain viscosity in water, suitable for dry environments

Strong chemical resistance, less suitable for labeling in chemical environments

Widely applicable and suitable for various occasions that require long-term label maintenance, such as outdoor environments, electronic products, automotive parts, and industrial supplies. The identification labels are narrow and suitable for some labels that require short-term use or in dry environments, such as stationery, school classroom labels, restaurant desktop labels, etc

Environmentally friendly and non-toxic, meeting the requirements of modern life for environmental protection. The vast majority of water-soluble solutions are environmentally friendly and non-toxic

Good stability and stability, but it is not easy to reattach after being damaged. Good stability and can be reattached in a short period of time

Relatively high and relatively low cost

In summary, hot glue and water-based glue each have their unique advantages and applicable scenarios in label paper applications. The decision on which type of adhesive to choose should be based on specific needs. If labels need to be used for a long time, in humid environments, or fixed in position, hot glue should be selected; If labels need to be replaced frequently, in dry environments, or require frequent cleaning, water-based adhesive should be chosen.
