A single-sided, slip resistant, self-adhesive material is produced using a blown film process which produces a film having an interior layer capable of being treated or coated to accept a pressure sensitive adhesive, a middle layer of flexible polyolefin and an exterior polyolefin elastomer layer in combination with a blowing agent to produce a single-sided slip resistant material. A number of in-line rollers are provided after a pair of rollers, which form part of a machine direction orienter (MDO) that is used in line in the manufacturing process to heat, and then cool and condition (anneal and relieve any stresses and/or thickness inconsistencies) the film prior to the film being coated on one side with a pressure sensitive adhesive. |
