How can labels be attached?

Labels can be attached to a surface many different ways. Some labels use adhesives, and pressure sensitive adhesives are quite common.

Pressure sensitive adhesives - also called PSA or self-stick - are applied with light pressure without activation or heat. PSA labels often have release liners which protect the adhesive and assist label handling.

Another form of label attachment is a heat activated adhesive. Heat activated adhesives: for example, "in-mold labeling" can be part of blow molding containers and employs heat activated adhesives. These are also common for adhering “iron on” patches to fabric surfaces.

• Other common forms for attaching labels include:
  Wet glue (starch, dextrin, PVA, etc) or water moistenable gummed adhesive
• String or Twine for tying on a label
• Rivets used to attach information plates to industrial equipment
• Shrink wrap for printed shirinkable labels placed over packages and then submitted to heat for shrinkage.
• Finally, good old sewing for attaching labels to clothing, tents, mattresses, industrial sacks, etc is still very popular.
