September 26, 2008 - Three levels of tear resistance allow users of Natralock® Security Packaging from MWV Corp., Richmond, VA, to match degree of product protection to needs. Options include Natralock NTR with Easy-Seal technology, Natralock ETR, Natralock GTR. Natralock NTR with Easy Seal technology relies on substrate’s inherent tear properties, provides most economical solution for non-secure products. Natralock ETR addresses applications requiring Elmendorf tear test specification: Tear strength remains constant even after tear has been initiated. Natralock GTR meets specifications of Graves tear test: Special construction of paperboard makes it extremely difficult to tear without nick with sharp object. Designed to replace clamshell packaging, Natralock fold-over or two-piece trap seal blister pack combines recyclable laminated paperboard card with clear amorphous polyethylene terephthalate (APET) or recycled PET thermoform to create package that uses 50%-60% less plastic than traditional clamshell. Although nearly impossible to tear apart, Natralock opens easily with scissors. Natralock packaging also offers choice of substrates including MWV Printkote® solid bleached sulfate, Printkote Eagle® or Custom Kote® coated natural kraft, or Kraftpak®.
