Void Filler Panels


SUNRISE SMALL CELL™ honeycomb is a viable option for load securement as well as interior and exterior packaging.  Lightweight, economical, recyclable, dense, and durable replacement for unitizing and dividing loads, in addition to a great replacement for foam and other corrugate options.  Some key applications for SUNRISE SMALL CELL™ honeycomb include (but not limited to):  bulkhead void filler panels for load securement, buffer and tier sheets, filling head space in tomato bins, furniture protection, window and door protection, and much more!

SUNRISE SMALL CELL™ honeycomb packs a punch with compression strengths from 5-63 PSI (0 to 10,000 lbs.) and allows us an alternative to some of our DIAMOND-PAK® large cell honeycomb panels shown below.  This also allows us to manufacture thinner panels (down to 3/8"), much thinner than we once manufactured with DIAMOND-PAK®.
