Types of adhesive labels?

[ad_1]

There are two basic types of adhesive labels: permanent and removable. Each type can be made from a variety of materials; which material to choose depends on the surface to be labeled, the conditions the label will have to withstand, the required longevity of the label and its purpose. The most popular types of label adhesives are acrylic, rubber, and water-based.

If a label is exposed to a very humid environment, such as a freezer, refrigerator, or cooler, water-based adhesives aren’t practical. They break and labels can fall off products, no matter what surface they are applied to. Water-based adhesives should only be used in dry rooms.

Adhesives composed primarily of rubber are preferred due to their tackiness. They are prone to failure when exposed to UV light for extended periods of time. If the labels won’t be exposed to sunlight, this type of adhesive works well.
Acrylic-based bonding agents are easy to work with during application, as they can be easily moved around. Once the acrylic glue dries, however, the bond is permanent. This type of label adhesive is suitable for long-lasting products that need labels to stand the test of time and frequent handling.

Depending on the surface to be labeled and the required durability of the label, there are six commonly used types of adhesives. Some types can be purchased at stationery or office supply stores. Other more specialized labels and stickers must be special ordered based on the specifications of the items to be labelled.

The six major types of adhesive labels include permanent, peelable, ultra-peelable, freezer or frost fixable, high tack, and static cling. Before choosing a label adhesive, many factors need to be considered. These include the size of the tag, the texture of the facade to be tagged and the level of mobility required; some, like retail labels, need to be removed at some point, and others, like shipping labels, can be left intact indefinitely.

If a label is attached with the intention never to remove it, or if only a solvent would remove it, it is called permanent. In some cases, before a tag reaches permanent status, it has a short period in which it can be moved. These labels are often referred to as repositionable.
A peelable label is just that – it can be peeled off the surface easily. The external surface is not damaged and there are no adhesive residues. This type of label can normally be used two or three times and does not lose its tackiness. An ultra-peelable label is commonly used on book covers and glass, where no residue is acceptable. These labels can only be used once before the adhesive is gone.

For labels that will be exposed to freezing temperatures, freeze or freeze stickers are preferred. They stand up to extreme cold without peeling or cracking. If you need a label to stick firmly to a dirty, warped or rough surface, you need a high tack glue. Static cling labels do not use a traditional adhesive but adhere to very smooth surfaces such as glass using only a static charge.
