24. When there are two different materials for round labeling machine glass bottles and plastic bottles, what is the difference between these two bottles while labeling? What should I pay attention to?
Basically, our round bottle labeling machine works very well for actual round containers. The label is attached to the position accurately and compliant. Generally, the plastic round bottle should be focused when it is labeled. If the bottle material is too soft, when the plastic is produced. When the round bottle blowing molding time and precision are not good or the plastic material of the bottle is not good, it will affect the positional accuracy of the labeling. Even if the bottle material is too thin, the label will wrinkle when it is attached. Therefore, it is recommended that you do not choose too soft when purchasing plastic bottles. When buying a bottle or measuring whether the bottle is a round bottle, you can directly roll the bottle on the glass table and test it to see the bottle and the gap between the glass and table. Then, you can see the level surface of the bottle.
When the round labeling machine is attached to the glass bottle, if the glass bottle of the true round bottle is attached with high precision, the glass bottle which is produced by the blowing method is often seen, because the thickness of the bottle would be different by blowing out. The thickness is different, which will cause errors or offsets in labeling. When you can't judge whether the bottle is a round bottle, it is recommended to observe the round bottle on the table and observe the gap between the table and the glass bottle to judge the roundness of the bottle, and also understand the glass bottle through the light refraction. Whether it is a true round bottle.
What if I have used a glass jar that is not a true round bottle and I can't change the bottle? It is recommended to change from making the label sticker. The size of the sticker should not be too long, because the difference in the shape of the bottle itself will make the sticker stick less skewed, and the overall appearance will be more beautiful.
