Dennison Wax Pick

The Dennison Wax Pick is a tool used for evaluating the surface strength of paper and paperboard. Each Wax Pick is made of a hard resin that is non-oily, ensuring reliable results. A box contains 8 sticks, all of the same grade. This tool is simple, easy to use, and cost-effective.

1. Heat the Waxes
   The waxes are gently heated and then applied to the surface of the paper or paperboard sheet.

2. Cooling Phase
   Allow the wax to cool naturally after application.

3. Testing the Surface Strength
   Once cooled, the wax is pulled from the sheet's surface.

   • The test determines if the wax pulls fibers or coating material from the surface.

4. Determine the Pick Strength
   The highest value of wax that does not rupture or damage the surface is recorded as the pick strength of the sheet.

• Waxes are heated and applied to surface of the sheet.
• After cooling waxes are pulled from the surface of the shape.
• Wax is used to check if it has pulled fibre of coating from the surface.
• The highest value wax, which does not rapture the surface, is reported as the pick strength of the sheet
