ABSTRACT:
A novel process for packaging goods within stretch-type plastic films. The process comprises the steps of preforming the package elements so that on-line sealing and long cooling cycles are not necessary during rapid packaging procedures when the film is extended under high stress. The required extension is achieved by the use of film-band spreading means which have low friction surfaces thereby minimizing any local stress on the expanding package material.
