Borden film links cold-seal porperties
Borden's Proponite Division combined cold-seal release and cold-seal adhesion properties in its new Apco biaxially oriented polypropylene film.
The North Andover, Mass.-based firm designed Apco for single-web, reverse-printed, cold-seal overwrap of multipackaged products such as snacks and candies.
Borden claims the film is printable without the need for primers and is less costly than alternatives that require over-lacquers to achieve cold seal.

Elkem says silica increases stiffness
Elkem Materials Inc. says its amorphous silica is a less-costly impact modifier for conventional and foam-core PVC pipe.
The Pittsburgh company indicates usage levels for impact strength are typically about three to five parts per hundred. The silica, which costs about the same as vinyl resin, also increases stiffness and aids in flow of dry material, Elkem claims.
