How to distinguish the quality of A4 stickers?

To distinguish the quality of A4 stickers, the following aspects can be considered:

1、 Material quality

Surface material: High quality adhesive labels use high-quality surface materials, such as water-resistant, heat-resistant, light resistant, and wear-resistant materials. These materials can maintain the integrity of labels in various environments, and are not easily deformed or damaged. At the same time, the surface gloss and color of the surface material should be consistent, with uniform density, to ensure the stability and aesthetics of the printing effect.

Bottom paper: The bottom paper should have good flatness and thickness uniformity to facilitate the complete die-cutting of the surface material. In addition, the strength of the backing paper is also an important factor affecting the quality of die-cutting and the effectiveness of waste disposal.

2、 Adhesive backing

Adhesive testing: High quality adhesive labels should have good adhesive properties, be able to adhere closely to various surfaces, and not easily peel off after long-term use. The adhesion of the backing adhesive can be tested by pasting the label onto surfaces of different materials and observing its detachment over a certain period of time.

Adhesive formula: The adhesive formula of self-adhesive is also an important factor affecting its viscosity. A high-quality adhesive formula can adapt to different surface materials and occasions, ensuring the stability and durability of labels in various environments.

3、 Print quality

Clarity: High quality adhesive labels print clearly, with bright colors and sharp text patterns. You can judge the printing quality by observing the text and patterns on the label.

Ink adhesion: Ink adhesion is also an important factor affecting print quality. High quality adhesive materials should have good ink adhesion to ensure that printed content is not easily peeled or faded.

4、 Cutting accuracy

Edge neatness: High quality adhesive labels should have neat cutting edges without burrs or edges. This can be determined by observing the edges of the labels.

Die cutting quality: Die cutting quality is also an important factor affecting the appearance and effectiveness of labels. High quality die-cutting technology should ensure accurate shape and size of the label.

5、 Durability

Wear resistance: High quality adhesive labels should have good wear resistance, which can maintain the integrity and clarity of the label during long-term use.

Weather resistance: The weather resistance of adhesive labels is also an important indicator of their quality. High quality adhesive labels can maintain their stability and durability in various harsh environments.

In summary, identifying the quality of A4 stickers requires consideration from multiple aspects such as material quality, adhesive strength, printing quality, cutting accuracy, and durability. When choosing adhesive labels, it is recommended to consider the actual needs and usage environment comprehensively to ensure the selection of high-quality products.
