Astir-Pak C1S

Astir-Pak is a high-yield C1S board that can meet your most demanding specifications in a wide range of food packaging applications. Our folding carton board brings together versatility and high level performance delivering superior print results and a structurally strong and rigid box.

Our Astir-Pak C1S board line gives you the winning combination of high yield properties and a triple coated smooth top surface with an uncoated natural white back that delivers consistent performance. It has superior high stiffness with standard weights and calipers with excellent folding properties. Due to its unique yield properties, Astir-Pak is considered the future of environmentally friendly paperboard grades. Using less material to package the same content saves on raw fiber and maintains a smaller carbon foot print. It is always good for business if you can save significantly in weight.
