ABSTRACT:
A chub cartridge containing a water-bearing blasting agent and having a film wrap of a cross-laminate of oriented film layers has at least one unlaminated zone in the film wrap in the longitudinal direction, or preferably is adapted to form a zone of multiple delaminations along said direction by virtue of scoring, the latter being the site of delamination when the cartridge has end-pressure applied to it with a tamping rod. The different layers fail in different directions along the unlaminated zone, affording a measure of integrity to the cartridge if roughly handled, as well as ease of rupture on tamping. The cartridge also has good abrasion and tear resistance, and dimensional stability.
