Reclosable Fasteners
* Non-adhesive versions available.
• Stiff hooks on one side of the fastener mesh
with pliable loops on the other side for secure
closure; peel one side away for opening
• Pressure sensitive adhesive-backed versions*
bond on contact to a variety of flexible and rigid
materials; variety of adhesive properties
• The larger the fastener area, the greater the
strength for holding weight and resisting
shear and peel
• Low profile option for applications where
thickness is more critical than number of
closures; 75% thinner than standard product
with fewer openings and closings
• Mushroom-shaped stems on one side of the
fastener interlock with identically shaped stems
on the other side for 5X greater closure strength
than hook and loop; peel apart for opening
• Pressure sensitive adhesive-backed versions*
bond on contact to a variety of flexible and rigid
materials; choice of specialized adhesive
properties (see charts on pages 5-8)
• Choice of stems per square inch:170, 250,
400 (higher the combined number, greater
the closure strength–see chart at right)
• Larger the fastener area, greater the strength
for holding weight and resisting shear and peel
• Low profile option for a snug fit with about
half the thickness of the standard products
