Overlamination films are probably not the first aspects of a pressure sensitive label that come to mind, but they serve a very vital function. In fact, the newest technologies are characterized by their functionality.

Overlaminates have been touted for their ability to offer protection of the label, but they can also assist in the aesthetic look of a product. The primary role of an overlaminate is to provide protection and durability of the label, but even that function is evolving. Modern overlaminates have become much more than just a sticky piece of plastic applied to a printed surface. 

“Overlaminates are becoming more functional,” says Tom Dupont, senior product manager, overlaminates, Avery Dennison. “The imported commodity products of using clear or matte BOPP films still represent the largest and lowest priced segments. Engineered films, various top coatings and specialized adhesive packages are now being developed for more specialized and complex label applications. The evolution of overlaminates extends to printer and ink OEMs to ensure the right product is selected for each print option.”

Modern overlaminates come in a variety of film and adhesive types and thicknesses. A label designer now has numerous options beyond a mass-produced commodity grade. Plus, sustainability has become a critical element of all new R&D.

“Another large area of evolution is the move toward a more sustainable overlaminate product,” explains Dupont. “The overlaminate must become a solution in the life cycle of the product instead of just another landfill component. Films, adhesives and synergies with labels and printing inks are being developed to assist in the recycle/reuse process of the package. 

“Work is underway to pair overlaminates with label materials to enhance circularity,” adds Dupont. “A label designer will soon have the ability to confidently select a certified pairing which assures that the label is not a hindrance to label and packaging reuse or recycle.”

Overlaminates are applicable for a wide range of markets. Overlaminates protect label print from chemicals, which could be spilled in home care, as well as health and beauty. Meanwhile, outdoor applications requiring enhanced UV protection from fading or deterioration are also good areas for overlaminates. 

“Overlaminates go pretty much anywhere one places a label,” states Dupont. “Now one can see overlaminates becoming part of the sustainability solution.”

Avery Dennison has engineered multiple new products to meet demand for overlaminate solutions. The company offers a full range of overlaminate products, ranging from the high volume commodity products to specifically designed items providing increased functionality, from haptics to enhanced UV protection. 

“AD overlaminates use a variety of films to work with a broad range of labelstocks,” comments Dupont. “Avery Dennison also has a certified lab to provide UL and BS certification of the complete label if it is constructed with AD labelstock and overlaminate.”
