The advantages and disadvantages of using glue for self-adhesive label paper

There are many kinds of glue used for self-adhesive label paper, and each glue has its own unique advantages and disadvantages. The following is a summary of the advantages and disadvantages of several common glues in the application of self-adhesive label paper:

Hot melt glue

Advantages:

Strong adhesive force: Hot melt adhesive has a strong adhesive force in the molten state, which can ensure that the label is firmly pasted on the object.

Fast curing speed: hot melt adhesive cures quickly after cooling, improving production efficiency.

Environmental protection and non-toxic: hot melt adhesive is mostly non-toxic or low-toxic materials, in line with environmental requirements, suitable for food, medicine and other fields of label paste.

Cons:

Sensitive to temperature: hot melt adhesive needs to be used at a specific temperature, and the sensitivity to temperature is high, low temperature environment may become hard and brittle, affecting the bonding effect.

Limited heat resistance: The heat resistance of hot melt adhesive is relatively poor, and it is not suitable for long-term use in a high temperature environment, otherwise it may soften or even melt, resulting in the label falling off.

Poor solvent resistance: hot melt adhesive is easily dissolved by organic solvents and may lose viscosity after contact with solvents.

Water glue

Advantages:

Environmental protection non-toxic: water glue with water as a solvent, non-toxic and tasteless, harmless to the human body and the environment.

Good adhesive force: water glue has good adhesive force and can meet the needs of general label pasting.

Strong temperature resistance: compared with hot melt adhesive, water adhesive has stronger temperature resistance and can be used in a certain high temperature environment.

Cons:

Long curing time: water glue takes a certain amount of time to fully cure, which may affect production efficiency.

Sensitive to humidity: A high humidity environment may affect the adhesive performance of the water glue, resulting in a decrease in adhesive strength.

Poor marking performance: If there is slight water or oil stains on the paste, the hydrosol is prone to drop the mark and tilt the mark.

Oil glue

Advantages:

Strong adhesive force: the oil adhesive has a strong adhesive force, which can ensure that the label is firmly pasted on various materials.

Fast curing speed: the curing speed of oil adhesive is relatively fast, which is conducive to improving production efficiency.

Not easy to be eroded by water: oil glue has a certain waterproof performance, suitable for use in humid environments.

Cons:

Irritating odor: Oil glue may produce irritating odor during use, which has a certain impact on human health.

Harmful to the human body and the environment: Some ingredients in the oil glue may cause harm to the human body and the environment, and it is necessary to pay attention to the safety of use.

Higher cost: Compared to other types of glue, the cost of oil glue may be higher.

Solvent glue

Advantages:

Strong adhesive force: solvent adhesive has a strong adhesive force, suitable for all kinds of material label paste.

High temperature resistance: solvent adhesive has good high temperature resistance, suitable for use in high temperature environment.

Cons:

Not environmentally friendly: solvent glue may cause pollution to the environment during production and use.

Toxic: Most solvent glues are toxic and harmful to human health.

High price: The price of solvent glue is relatively high, which increases the production cost.

In summary, different types of glue have advantages and disadvantages in the application of self-adhesive label paper. When selecting glue, it is necessary to comprehensively consider factors such as the specific application scenario, the material to be affixed, the use environment, and safety requirements.
