Heat sensitive label paper is better to use water glue, or hot glue

Thermal labels use water glue or hot glue, which mainly depends on the specific application scenarios and needs. Here is a detailed analysis of the pros and cons of both to help you make a more appropriate choice:

Water adhesive thermal label paper

Advantages:

Environmental protection and non-toxic: Water adhesive thermal label paper uses water-based glue, non-toxic and tasteless, in line with environmental requirements.

Moderate price: Compared with hot glue, the price of water glue thermal label paper is usually lower.

Widely used: Due to its excellent adhesion, water adhesive thermal label paper can be widely used in various material surfaces.

The stronger the adhesive: there are two layers of water adhesive, including water-based adhesive layer and permeable layer, although the initial adhesive fastness is weak, but over time, the bonding effect will gradually increase.

Long storage time: Water adhesive thermal label paper can be stored for a long time under appropriate storage conditions.

Cons:

Slightly weak adhesion: Compared with hot glue, the adhesion strength of water adhesive thermal label paper is weak.

Poor water resistance: If soaked in water for a long time, water adhesive thermal label paper may not be easy to maintain the integrity of the label.

Hot-glue heat-sensitive label paper

Advantages:

Strong adhesion: Hot glue Thermal label paper uses hot melt adhesive, adhesion strength is large, and the object is firmly bonded.

Good water resistance and chemical resistance: hot adhesive thermal label paper can be used in a humid environment for a long time, and has good chemical resistance.

High initial adhesion: hot melt adhesive can be quickly bonded when in contact with the adhesive, and the initial adhesion is very high.

Cons:

Slightly higher price: The price of hot adhesive thermal label paper is usually higher than that of water adhesive thermal label paper.

There are requirements for the use of the environment: hot melt adhesive may not be used in a low temperature environment, and the decline rate is faster, and the viscosity will gradually weaken.

The labeling process is complicated: When using hot-glue thermal label paper, it is necessary to ensure that the labeling environment is suitable to avoid adhesion problems caused by temperature changes.

conclusion

When choosing water adhesive or hot adhesive thermal label paper, the following factors should be considered comprehensively:

Application scenario: If labels need to be exposed to moisture for a long time or withstand chemical corrosion, you are advised to use hot-adhesive heat-sensitive labels. If the application scenario is relatively dry and the adhesion requirement is not particularly high, water adhesive thermal label paper may be a more affordable option.

Cost budget: The price of hot-glue thermal label paper is usually higher than that of water-glue thermal label paper, so the cost budget is also an important consideration.

Labeling process: If the labeling process is relatively complex or has high requirements for the labeling effect, it may be necessary to choose a hot adhesive thermal label paper with higher initial adhesion and stronger adhesion.

To sum up, there is no absolute "good" or "bad", and the choice of which type of thermal label paper should be determined according to the specific application scenarios and needs.
