Overview

• Ashland and Michelman have partnered to develop water-based barrier systems (WBBS) for paper and paperboardbased barrier systems (WBBS) for paper and paperboard packaging

• A novel "base coat" for WBBS was recently developed and• A novel base coat for WBBS was recently developed and validated in several grades of paper and paperboard

• Improves water, oil and grease resistance and reduces moisture vapor transmission rate of WBBS

• Performs better and costs less than other technologies and offers a number of environmental benefits

Overview of Novel Base Coat for WBBS

• Ready-to-use product serves as a low-cost "primer" (2-4 g/m2)

• Applied at the size press or coater

• M difi d i th f t h f• Modifies and improves the surface topography of paper and paperboard without sealing

• Holds more expensive top coat at surface• Holds more expensive top coat at surface

• FDA-approved formulation is a patent pending combination of mineral binder and cationic crosslinkercombination of mineral, binder and cationic crosslinker

• Marketed as Dimension™ BC1060 converting additive

Benefits of Novel Base Coat for WBBS

• Improved water, oil and grease resistance

• Reduced moisture vapor transmission

• Reduced cost of total barrier package• Reduced cost of total barrier package

• Reduces or replaces wax and polyethylene coatings

• Eliminates the use of fluorocarbons

• Allows for the increased use of renewable materials and improves the ease of recycling
