As we all know, self-adhesive stickers are sticky, and bubbles are more likely to be generated in the process of applying stickers, which will directly affect the adhesive effect and externality of the label. The following will introduce two more commonly used sticker problems and their treatment methods. They are: transparent film type self-adhesive stickers attached to the transparent bottle body will produce bubbles.
Factors that cause bubbles: uneven surface of the bottle body, small depressions, or the softness of the label to match the bottle body will produce bubbles; the labeling method of the sticker machine matches the appearance design of the bottle body, or the labeling method is inappropriate, Air will remain in the sticker and generate bubbles.
process:
1. Transparent special self-adhesive labeling machine, the label adopts a rubber scraper;
2. Use materials that match the material of the bottle body to print bottle stickers;
Before applying the sticker, check whether the surface of the bottle mouth is flat. If leveling is not performed, the mold for producing the bottle body should be leveled.
The second problem: air bubbles are generated when a large number of paper labels are attached to vessels such as oil drums.
The reason for the bubbles: The storage environment of the sticker is too different from the temperature and humidity in which it is located, which results in the rapid absorption of moisture after the label is applied and the generation of bubbles. Or it is because the surface of the sticker is not flat or there is stains that produce blisters, which causes the label to be not firmly attached and causes bubbles.
process:
1. Before sticking the sticker, place the sticker in the sticker environment for a period of time to make it balance with the humidity of the environment;
2. Keep the surface of the labeling object dry and clean, and sticking the labeling object flat and firmly at the labeling place.
