Factors that determine the adhesion of decal labels

Factors affecting the adhesion of labels and stickers.

Several factors affect the adhesive strength of labels, including:

1. Surface components:

• Plastics, glass, paper, cardboard, wood, metal, and fabric  all have different compositions, which affect the effectiveness of the label adhesive.
• Plastics:  Some types of plastic, such as PP and PE, have weaker adhesion than others, such as PET and PVC.
• Metals:  Metals typically have smooth, slippery surfaces, making it difficult for adhesives to bond.

2. Surface texture:

• Smooth surfaces  (like glass, metal) make it more difficult for adhesives to stick compared to  rough surfaces  (like paper, cardboard).
• Rough surfaces  can cause labels to peel off.

3. Surface shape:

• Curved surfaces  are more difficult to apply labels to than  flat surfaces .
• Surfaces with many edges  can cause labels to tear.

4. Surface cleanliness:

• Dirty, dusty  , or  greasy surfaces   will reduce the adhesive's bonding strength.
• The surface must  be cleaned  and  dried  before applying the label.

5. The surface is damp:

• Adhesives will have difficulty adhering to  damp surfaces .
• Ensure the surface  is dry  before applying the label.

6. Temperature:

• Temperatures that are too high  or  too low  can affect the adhesive strength of the glue.
• Labels should be applied at  room temperature  (approximately 20-25°C).

7. Label quality:

• Poor quality labels   may use inferior adhesive, resulting in weak adhesion.
• You should choose to buy labels from reputable suppliers.

In addition, several other factors can also affect the adhesion of labels, such as:

• Storage time:  Label stickers should be stored under appropriate conditions (temperature, humidity) to ensure the quality of the adhesive.
• Pressure when applying:  The label needs to be pressed with just enough force to ensure proper adhesion.

To increase the adhesion of your labels, you can apply some of the following measures:

• Use labels that are appropriate for the type of surface they will be applied to.
• Clean and dry the surface before applying the labels.
• Apply labels at room temperature.
• Use a specialized labeling machine to ensure the correct amount of pressure is applied.
• Store labels and stickers under appropriate conditions.

Choosing a quality label printing factory

To choose high-quality label printing, you need to consider the following factors:

1. Identify usage needs:

• Intended use:  Labels for product packaging, warranty labels, barcode labels, etc.
• Quantity to be printed:  Small or large quantities.
• Label size:  The size should be appropriate for the product and the information to be displayed.
• Label materials:  Paper, decal, plastic, etc.
• Label colors:  Colors that match the brand and product.

2. Choose a reputable printing company:

• Experienced in label printing:  Ensuring high-quality printing, accurate colors, and sharp labels.
• We have modern equipment:  state-of-the-art printing machines, ensuring fast printing and the ability to handle large quantities.
• Competitive pricing:  Reasonable quotes, with many special offers for customers.
• Excellent customer service:  Enthusiastic advice and support in designing labels according to requirements.

3. Some things to note when printing labels:

• Provide all necessary information:  Product name, logo, contact information, ingredients, usage instructions, etc.
• Carefully review the design file before printing:  Ensure the information is accurate, the layout is logical, and the colors are correct.
• Request a print sample from the printing company:  Check the print quality before printing in large quantities.
