CustomKote® Poly

custom kote poly product

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.


Features & Benefits

What you can expect from us:


Strong softwood fibers deliver excellent strength and performance for dry, refrigerated and frozen environments.


A unique LDPE barrier coating provides resistance to moisture, oil, and grease.


A top layer of hardwood fiber and proprietary clay coating provide a smooth, opaque surface to enable crisp, vibrant graphics for maximum shelf appeal.


Achieve desired stiffness-to-weight ratios at lower calipers and lower weights than competitive substrates, which supports cost reduction and sustainability initiatives.


Enables flexibility in packaging design with features such as handles, windows, and apertures.
