As part of Wisdom Adhesives overall strategic plan to continue on it’s path as the leading customer focused adhesive supplier in the industry, Wisdom Adhesives announces the introduction of a new & improved PolyTak™ Hot Melt adhesive technology for the Packaging Industry. Key features of the product line are listed below:
|
PolyTak adhesives offer excellent adhesion properties. |
|
PolyTak adhesives offer excellent thermal & pot-stability – tops in adhesive industry. |
|
Clear / White in color. |
|
PolyTak adhesives offer increased mileage due to lower density and higher performance – often resulting in a minimum of a 15% to 25% reduction to the overall cost vs. standard competitive products. |
|
Eliminate downtime and maintenance costs. |
|
Eliminate gels and charring. |
|
Low odor. |
|
Economical – from an extended mileage, performance and density standpoint. Compares favorably vs. competitive EVA and other olefin based adhesive products. Up to 15%-25% savings! |
|
Extended runability – excellent pot stability. |
|
New technology is easy to run and easy to use. Just another reason to convert to Wisdom Adhesives. |

THERMAL STABILITY
Improved Mileage: PolyTak Technology can be expected to save up to 25% advantage in mileage based on superior aggressive adhesion technology (lowering bead size) and lower density not factored above in savings example (0.91 vs. 0.97); both resulting in the use of less adhesive usage vs. EVA based technology.
Better Thermal Pot Stability: Please see the images below; indicating the color change of PolyTak type technology vs. EVA based technology when held for hours/days at application temperatures. This better pot stability will result in longer pot-life for less waste, wider service temperature range, reduced downtime and maintenance costs and adherence to a wider range of surfaces. No downtime!
