发明名称 Shrink-film packaging method
摘要 An improved method involving forming a generally cube-shaped package made up of a plurality of rows of plural individual sub-packages of the articles being packaged and which package is overall embraced and stabilized by a heat-shrinkable plastic film material. The improvement resides essentially in initially forming smaller separate sub-packages of predetermined and usually like-multiples of the aligned multiple articles and relatively loosely wrapping them essentially on all sides except perhaps their supported surface with a heat shrinkable material, subjecting the so wrapped sub-packages to heat to shrink fit the wrappings and consolidate the articles therein; then accumulating the separate shrink-fit-wrapped sub-packages closely adjacent one another to constitute a given size layer or tier, subsequently stacking and maintaining a plurality of the sub-packages in a predetermined number of plural superposed rows or tiers and often upon or in conjunction with suitable auxiliary lower level stabilizing members, subsequently wrapping both at least part of the auxiliary stabilizing members and all of the superposed plural tiers of the sub-packages within an overall enveloping heat-shrinkable shroud of the film, and then subjecting the stack of wrapped articles to heat to shrink-fit the outer wrapping around the complete assembly thereof. An alternate method contemplates layering sub-groupings of the articles into plural side-by-side horizontal rows of the articles and heat shrink fit wrapping the full layer with the heat-shrink film, rather than individual rows comprising a given layer.
