Detection of transversal and longitudinal seals of a package composed of a laminated material

摘要

A method and means of detecting the seals of a package is disclosed herein. The invention includes coloring the inner coating of a laminated material that is used to create a package on a form, fill and seal packaging machine. The invention also discloses coloring the longitudinal strip of the package. The coloring of the inner coating allows an operator to distinguish between an acceptable seal and a defective seal since a delamination, which is acceptable, may appear to be a defective seal without the inner coating coloring. The colored longitudinal strip also allows one to distinguish between a defective longitudinal seal and a delamination of the longitudinal strip.
