What type of adhesive is usually used for circular colored copperplate labels?

The types of adhesive commonly used for circular colored copperplate labels include the following:

1、 Pressure sensitive adhesive

Pressure sensitive adhesive is the most commonly used type of adhesive in self-adhesive labels, with good adhesion and initial adhesion, and can firmly adhere to various surfaces such as glass, plastic, metal, etc. For circular colored copperplate labels, pressure-sensitive adhesive can provide stable and reliable adhesion performance, ensuring that the label is not easily peeled off or curled during use.

2、 Specific types of adhesive

Water based adhesive:

Features: Non toxic and harmless, excellent environmental performance. But the drying speed is relatively slow, and it takes some time to achieve the best bonding effect.

Applicable scenarios: Suitable for situations with high environmental requirements and low requirements for pasting speed.

Acrylic lotion:

Features: Quick drying, strong adhesion, high transparency, will not affect the appearance of the label. But when using, it is necessary to pay attention to controlling the amount of glue to avoid affecting the appearance of the raw materials.

Applicable scenarios: Suitable for situations that require quick pasting and high requirements for label appearance.

Oil glue:

Features: Fast drying speed, strong viscosity, but may turn yellow after drying and easily pollute the surrounding environment. Therefore, special attention should be paid to controlling the dosage and avoiding glue leakage during use.

Applicable scenarios: Suitable for pasting heavy or rough surface labels, as well as situations with high requirements for adhesive drying speed. However, considering its environmental friendliness and impact on the appearance of labels, the application of oil-based adhesives in circular colored copperplate labels is relatively limited.

Hot melt adhesive:

Features: High viscosity, stable adhesion, and does not require too much time. But after tearing, there may be a large brushed shape, which makes it difficult to tear off the folds.

Applicable scenarios: Commonly used in industries such as express delivery, milk tea, food, clothing, and foreign trade that require cost control.

3、 Choose suggestions

When choosing the type of adhesive for circular colored copperplate labels, the following factors need to be considered:

Usage environment: Select the appropriate type of adhesive based on the usage environment of the label, such as temperature, humidity, lighting, etc. For example, labels used outdoors or in high-temperature environments need to choose adhesives with better weather resistance.

Surface of the sticker: Select the appropriate type of adhesive based on the material and surface characteristics of the sticker. For example, for rough or uneven surfaces, it may be necessary to choose a stronger adhesive to ensure the bonding effect.

Cost considerations: While ensuring the adhesive effect, the cost of glue needs to be taken into account. The prices of different types of adhesives vary greatly, and it is necessary to choose according to actual needs.

To sum up, the glue types commonly used in round color copper plate labels include pressure sensitive adhesive and its specific types, such as water-based adhesive, acrylic lotion, oil-based adhesive and hot-melt adhesive. When making a selection, it is necessary to comprehensively consider factors such as the usage environment, the surface of the sticker, and cost.
