Learn about the solution to blistering and warping of self-adhesive stickers

How users often encounter bubbles when pasting. Is there any way to avoid this? What is the reason for the blistering and warping of the self-adhesive paper?

Reason 1: Static electricity makes the sticker blister

In northern China, it is usually very dry, the labeling machine is easy to generate static electricity during the automatic labeling process, and the sticker can easily cause the sticker to blister. In addition, during the labeling process, the contact and friction of bacteria between the self-adhesive paper and the self-adhesive paper and the labeling machine produce advertisements, which cause the self-adhesive paper to blister.

Solution:

1. Maintain the temperature and temperature of the operation workshop, the temperature is generally controlled at 20-22℃, and the temperature is maintained at 50%;

2. Use copper wire to discharge

Reason 2: The reason for the manual label body

There are several possibilities:

1. The shape of the label body is not flat, such as flat or regular;

2. There are glue, impurities, etc. on the label body, and the chemical reaction causes the self-adhesive paper to foam;

3. The material is not selected by the label body material

Solution

1. During the labeling process, the labeling body needs to be fixed with a conveyor belt

2. Clean and dry the label before labeling

3. Choose according to the material of the label body, such as transparent glass or plastic body. Soft bottle body hard plastic bottle pe, pvc film material, material pet, bopp; choose a suitable good base paper, such as pet material.

Reason 3: The pressure source of the labeling machine roller

In the automatic labeling process, the last step of the labeling machine is to smoothly stick the self-adhesive paper to the product through the pressure roller. If it has pressure paper, the label paper will not fit completely, resulting in blistering.

Solution: Contact the labeling machine supplier to adjust the machine.

Reason 4: The glue on the self-adhesive paper is uneven

In the process of producing self-adhesive paper, if the label printing factory does not apply the glue in time, sparkling wine will also become popular.

Avoidance method: When purchasing self-adhesive paper, choose a strong self-adhesive printing factory, such as Hezhong logo label manufacturer, and choose good quality paper labels.

How to choose barcode paper and sticker paper?

Often when we first choose to buy something, we don't know where to start. The same goes for choosing barcode stickers. Let's take a look with me below.

Barcode paper labels, stickers. It is a commonly used consumable material for barcode printers. Usually printed in software using wax-based or mixed-based ribbons. The content can be text, numbers, pictures, one-dimensional bars, two-dimensional barcodes, etc. Types are: copper paper, pet, pvc, thermal transfer paper, removable self-adhesive labels, thermal paper, strip paper, synthetic paper, pearl film, etc., matt silver, bright and other code silver paper.

Select barcode paper first few questions:

①Is your printer a label printer/barcode printer?

②What bearing material is the label attached to? Clothing labels? Jewelry, jewelry? supermarket? Fruit shop? Fixed assets?

③What is the surface state of the pasted product (eg: What is the surface state of the pasted product? (For example: What is the surface state of the pasted product?)

④Is there any special consideration for the environment? (For example: outdoor climate, sun exposure, strong sunlight will easily debond the glue, and the low temperature studied will affect the danger of glue)

⑤ Does the printed content of the label need to be persistent? Scratch resistant? washable?

After understanding the above questions, I believe you probably know the labels you need to grow up.
