The problem of bubbles on the label of the bottled water filling machine

Bottled water filling machine are generally only caused by the transparent labels, and they look ugly. This is a problem that plagues most manufacturers. To solve this problem, we must first know the reasons for the bubbles caused by the labeling.

The specific reasons for the bubbles in the labeling of the bottled water filling machine are as follows:

1. There is dust or dirt on the bottle.

2. The bottle was not blown well when it was blown, and there were uneven pits.

3. There is static electricity on the bottle, which will repel the label and cause air bubbles.

4. Static electricity is generated when the label is peeled off from the backing paper, which is also the cause of bubbles in the labeling, which generally occurs on high-speed labeling machines.

After knowing the reason, let's see how to deal with it:

1. Make sure the bottle is clean and tidy before labeling.

2. Install electronic anti-static equipment to reduce the influence of static electricity.

3. Use a spring steel sheet plus a brush or a spring steel sheet plus a sponge or a silicone scraper. If the bottle is flat and the label is no problem, as long as the correct scraper is selected, there will be no bubbles.

4. If it is a can filling machine, it is best not to use transparent labels, because the bottle itself has some irregular surfaces, so bubbles are difficult to avoid. If you really want to use transparent labels, then use spring steel sheets with brush effect or spring steel Flakes and sponges would be better.

5. When labeling, the running speed of the bottle body should be slightly faster than the labeling speed of the label, so as to avoid the occurrence of air bubbles.

6. For soft bottle labeling, it is necessary to adjust the relationship between labeling speed, scraper strength, angle and distance.
