Lamination Adhesives For Flexible Packaging

Nowadays flexible packaging has reached the diversity that we probably could never think of when it first appeared.

That places the use of a single material on the verge of being unable to bring demanded properties to the table. To such concerns, compositing two or more material layers perhaps is the finest solution to take.

Lamination, in that sense, has gradually claimed its irreplaceable presence and position in pre-printing processes of material handling. Lamination adhesives have also evolved, enabling all sorts of possible features and configurations that power manufacturing capabilities while getting desired productivity and performance pulled off.

Let’s get to know Tomoflex™ and Ecoad™, two representative series for lamination adhesives from Toyo-Morton while taking a look at some of usual matters with lamination in flexible packaging production.

High Solid Coating

VWith our latest technology, lamination adhesives are now able to perform at a higher solids content, meaning less Ethyl Acetate (EA) to use for dilution.
