Applicable Base Polymer Properties

Waterborne EVA adhesives for case sealing have good flexibility, low temperature properties and adhesion to coated papers. These adhesives provide a low to medium performance relatively inexpensive adhesive that dries quickly. A typical formulation consists of VAE latex, filler (if greater viscosity is desired), plasticizer (for improved flexibility), and water.

Resulting Properties

The low viscosity of the water emulsion and its fast setting capability provide an excellent adhesive for sealing of corrugated boxes, cartons, and paper bags. The table above provides a formulation for a VAE adhesive that will provide a fast set and good penetration into the porous substrates. The latex adhesive dries to a somewhat rubbery film by virtue of the flexible nature of the copolymer. The adhesive has good resistance to water and good adhesion to most substrates.
