Strength Packaging Substrates

Durable, Eye-Catching, Heavyweight Folding Boxboard

Designed to maximize shelf impact, Dura-Fibre’s heavyweight folding boxboard combines superior strength with a dynamic appearance that elevates brand awareness and captures customer attention when used in strength packaging. To create high caliper substrates for consumer packaging, we glue together multiple plies of top-quality paperboard to make a very thick and strong laminated paperboard. In fact, Dura-Fibre’s paperboard is 50 percent stronger than the strongest single-ply Solid Bleached Sulfate (SBS). Sourcing higher quality paper provides our customers with a superior carton at the lowest total cost.

Strong container. Strong look. Lowest total cost.

Heavyweight Folding Boxboard

More Durable and Eye-Catching than Corrugated Cardboard

Our substrates are used to create folding cartons strong enough to ship notoriously heavy products like beverages and confections, something the thickest mill-provided folding carton board struggles to do. And it’s the superior product for handling burst, puncture and freeze/thaw scenarios – especially in the club store channel. We match that strength with plies of the brightest and best printing paperboard to make certain your brand stands out on the shelf, without the flute lines created by corrugated cardboard.

Leading brands in a wide range of industries choose Dura-Fibre’s heavyweight folding boxboard for their consumer packaging applications. In fact, brands focused on club channel distribution rely on Dura-Fibre substrates to produce folding cartons and other folding packages for durable, attention-getting packaging needed for club and warehouse stores:

  • Food
  • Beverages
  • Dairy
  • Confections
  • Electronics
  • Pharma
  • Spirits
  • Displays
  • Signage
  • Cosmetics
  • Accessories
  • Appliances
