Beverage label needs to have a strong permanent adhesive, so it can stick even in wet conditions. Manufacturers are increasingly becoming interested in self-adhesive labels, because they are 100% resistant to humidity and ice, and provide longevity, flexibility and possibility of more creative solutions. Self-adhesive is becoming a preferred type of label among wine producers. Some manufacturers still use wet glue paper labels, though, especially in the beer market. This could be the case because of lower cost, and because wet-glue labels are suitable for large volumes.
Here are the most commonly used types of beverage label adhesives:
- Permanent Self Adhesive
- Wet Glue
- Removable Self Adhesive
Permanent Self Adhesive
Permanent labels are usually very difficult to remove and if you insist on it, you’ll probably rip the label and leave sticky residue on the bottle. Permanent labels should be used when you are sure you will not need to remove the label. The adhesion speed varies between labels. Sometimes the label sticks fully the minute it is applied (high tack adhesive), and other times it can be easily removed in the beginning, until the full adhesion develops (sometimes it takes minutes, and sometimes hours).
Wet glue labeling technique is commonly used for glass bottles, jars and plastic (PET) containers. Machines which apply labels use glue which is liquid at room temperature. The machines are suitable for wet conditions (like liquid filling in beverages), which is why this adhesive type is particularly used for beverages. These labels are highly decorative, can be die-cut into various shapes and applied to difficult surfaces.
Removable Self Adhesive
Removable or peelable label is a strong adhesive that, once applied, will not come off the bottle easily. However, if you want to remove the label, you should be able to remove it without tearing the product or leaving sticky marks on the product’s surface. Removable labels can also be ultra-removable, which means they should only be used for products where light application and ultra-easy removing of the label is welcome.
