Title:
PACKAGED EXPLOSIVE PRODUCT AND PACKAGING PROCESS THEREFOR
Document Type and Number:
WIPO Patent Application WO1999000251
Kind Code:
A9
Abstract:
A packaged product has an explosive article packaged in a film. Although the film can comprise any one or more of a wide variety of polymers, the film is non-crosslaminated and is sealed to itself, and has a total free shrink at 185 DEG F of less than about 5 percent. The explosive article preferably comprises a flowable explosive composition. Preferably the film is lap-sealed along its length and clipped at the ends, with the package being in the form of a chub. The relatively low total free shrink at 185 DEG F enables the film to be used in a vertical-form-fill-and-seal packaging process in which a lap-seal is formed using a hot-melt adhesive composition. The relatively low free shrink of the film allows the film to be sealed using a hot melt type adhesive, without the film shrinking back to such an extent that the resulting seal is defective.
