CustomKote® Poly

Guards against grease, moisture and negative consumer perceptions.
Grease and moisture can wreak havoc on packaging. So for applications where a barrier is critical, turn to CustomKote® Poly. This Coated Natural Kraft® (CNK™) paperboard delivers high performance via a low-density polyethylene (LDPE) coating. It’s available one-sided (P1S) or two-sided (P2S) in a wide range of surface finishes to meet your specific appearance and printability needs.
