42" x 250' - 'B' Flute Kraft Singleface Corrugated Roll

This 42" x 250' kraft singleface corrugated roll uses B-flute construction — a single flat liner bonded to a fluted medium with approximately 1/8" raised fluting. That flute height strikes a balance between crush resistance and pliability, allowing the roll to conform around curved and irregular surfaces without cracking or buckling, which sets it apart from stiffer C- or A-flute alternatives.

The roll is well suited to warehouse pick lines, manufacturing facilities, e-commerce fulfillment centers, and retail distribution operations. Typical applications include wrapping individual items before boxing, interleaving between stacked or nested products to prevent surface contact, and lightweight void fill in larger cartons where rigid inserts are impractical.

Constructed to ECT-32-B single-wall specification, the kraft facing resists abrasion and minor impact during transit and storage. Each roll weighs approximately 54 lbs and is sold individually. Ships via parcel carrier.
