PSA Adhesive labels

Pressure sensitive label adhesives are commonly made from water based acrylic adhesives, with a smaller volume made using solvent based adhesives and hotmelt adhesives. The most common adhesive types are:

• Permanent -Typically not designed to be removed without tearing the stock, damaging the surface, or using solvents. The adhesion strength and speed can also be varied. For example, full adhesion can be nearly instant, or the label can be almost removable for a short period with full adhesion developing in minutes or hours (known as respositionable adhesives).
• Peelable -Adhesion is fairly strong and will not fall off in normal circumstances, but the label can be removed relatively easily without tearing the base stock or leaving adhesive behind on the old surface. The adhesive is usually strong enough to be applied again elsewhere. This type is frequently known as 'removable'. There are many different types of removable adhesives, some are almost permanent, some are almost 'ultra peelable'.
• Ultra-peelable -Designed principally for use on book covers and glass, when removed these adhesives labels do not leave any residue whatsoever. Adhesion is weak and only suitable for light duty applications. Normally these labels have very little adhesion to anything once they've been removed.
• Freezer or Frost fix -Most permanent and peelable adhesives have a service temperature limit of -10 degrees Celsius, whereas freezer (otherwise known as frost fix) adhesives have a service temperature -40 degrees Celsius and are suitable for deep freeze use.
• High Tack -A type of permanent adhesive that exhibits a high initial grab to the application surfaces, and is commonly used at higher coat weights to enable labels to adhere strongly to difficult, rough or dirty surfaces.
• Static Cling -This is not actually an adhesive at all. The material (usually PVA) has a static charge to enable its adhesion to flat, smooth surfaces such as glass. It is not sticky as such and is commonly used for window advertising, window decorations, oil change labels, etc

Stock types

The "label stock" is the carrier which is commonly coated on one side with adhesive and usually printed on the other side. Label stocks can be a wide variety of papers, films, fabric, foils, etc.

• Puffy - either water, gel, foam, or air-filled create a soft, raised sticker.
• Litho - one of the most common base stocks
• Latex - a litho stock with some added allows the label to be much more flexible and form around certain curved objects more easily than standard litho.
• Various such as , , and allow a variety of features, such as greater ,^[], , resistance to tearing, etc. They typically require special and methods ( curing is common) as they do not normally print well with conventional . A is usually a vinyl label with a very strong, durable adhesive and lightfast inks. is "printed" by pressing raised elements similar to onto it, which produces raised glyphs that look white due to discoloration of the plastic. A type known as 'Destructible Vinyl' is commonly used for asset labels. It combines a very thin frangible face stock with a very strong high tack adhesive, thus making the label impossible to remove without damaging it.
• Foil - has the shiny properties of a metal .
• Thermal - direct thermal label stock will change (usually ) when heated. A heating element in the shape of or can be used to create an image on the label. Custom labels can be easily be made on location in this way. A disadvantage is durability, because another heat source can ruin or obscure the image, or it may fade completely over time.
• Thermal Transfer for applications that cannot use Thermal (Thermal Direct) label material because of heat source proximity or short label life, a more widely used material is Thermal Transfer . This material has the advantage of a much longer readable life and does not fade with time or heat. Most major manufacturers of Thermal Printers can be used for either Thermal Transfer (TT) or Thermal (DT) labels. A thermal transfer ribbon will be required to print the labels. The cost of the ribbons + TT labels is similar to that of the DT labels on their own.
• None - labels can be printed directly on adhesive without using a . Labels made in this manner are extremely fragile, however, and have been rendered virtually obsolete by other printing methods such as .
• Thermal Transfer Ribbon Types
  • Wax is the most popular with some smudge resistance, and is suitable for matte and semi-gloss paper labels.
  • Wax / Resin is smudge resistant, suitable for semi-gloss paper and some synthetic labels.
  • Resin is scratch and chemical resistant, suitable for coated synthetic labels.

The stock type will affect the types of ink that will print well on them.

Corona treating or flame treating some plastics makes them more receptive to inks and adhesives by reducing surface tension.

We also offer Roll and sheet labels.
