Adhesive materials are prone to problems

Advantageous problems when selecting adhesive materials - plasticizers often leak out on the surface of soft PVC, and special attention should be paid when selecting adhesives. For cylinders with diameters of less than 30 mm, materials must be carefully selected;

When the label size is too small or too large, practical tests should be taken.
Labeling environment and temperature can affect the properties of adhesives, such as multi-water or multi-oil environment;
The object to be affixed is an irregular surface or even spherical;
Automatic labeling machine labeling should be tested;
Even if it is labelled at room temperature, is it experiencing high temperatures during export transit?
Corrugated cartons have a rough surface and are coated with varnish, which can affect labeling.
