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.

PolyTak PT3000 PolyTak PT3000 is a high performance, medium set polyethylene based hot melt for case, carton and tray sealing applications. PolyTak PT3000 exhibits excellent hot tack which will adhere to difficult surfaces. It also has excellent machinability and offers an approximate 10% less usage rate vs. EVA based products based on density.

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!
