Please check out our recent innovations below regarding water borne coating substitutes for PE extruded films and coating treatments to increase the rigidity of the corrugated medium.

We hope you enjoy your visit to Calchem, and welcome to the world of possibilities that Calchem offers you for your printings and packaging needs.


Aqueous Coating Substitute for Polyethylene (PE) Extruded Films

We have recently developed a water borne coating alternative to PE extruded plastic film lamination for sheet-fed and rotary applications.

This technology is based on a special formulated polymeric emulsion combined with inorganic mineral chemicals, without incorporating paraffin wax, silicone, or Teflon additives.

Barrier properties with respect to moisture, oil, and grease resistance are excellent. This coating technology is in compliance with the green environmental policy and is recyclable according to FDA code.


Enhancement of the Corrugated Rigidity

We have also recently developed a breakthrough coating technology to increase the rigidity of the corrugated medium.

This enhanced stiffness arises from a treatment of the corrugated medium by a special formulated coating. The treated system shows excellent Cobb values, a 30-40% increase in paper strength, and a significant decrease in deterioration of the paper strength in humid environments.

Overall, this is a remarkable technological advance from Calchem that we are excited to launch.
