Methods for bundling together groups of two or more articles for selectively obscuring individual identification codes on the articles and related assemblies are disclosed. In one embodiment, the method includes forming a composite film sleeve partially of a clear or transparent film and partially of a colored, opaque, or patterned film. The composite sleeve is then placed over a group of two or more articles slated for bundling and shrunken, if necessary. As a result, any advertising indicia or product information can be viewed by an observer, but the individual identification codes are obscured. Alternative methods of obscuring individual identification codes on groups of articles in a bundle while allowing for the visualization of the advertising indicia or product information thereon are also disclosed.

1. A method of forming a single, separately identifiable bundle of articles, comprising the steps of:providing a group of articles, each article having an individual identification code on a surface thereof;placing a first film at least partially over the group of articles, the first film at least partially exposing at least one surface of one of the articles for viewing;placing a second film at least partially over the group of articles, the second film substantially obscuring the identification code on another surface of each article;at least partially securing the first film to the second film on at least two sides of the group of articles to form a sleeve; andshrinking the sleeve to form the bundle.2. The method according to claim 1, wherein the first film is a clear, transparent film and the second film is a colored, opaque, or patterned film capable of obscuring the individual identification codes.3. The method according to claim 2, wherein:the first and second films comprise polyethylene films fed from continuous rolls, andsecuring the first film to the second film includes forming a first seal from the loose ends of the first and second films before the placing steps, and then using a heated device or cutter for simultaneously severing the first and second films from the continuous roll and forming a second seal adjacent a second side of the bundle after the placing steps.4. The method according to claim 1, wherein the step of placing the films includes advancing a first group of a plurality of articles into a first seal formed between the free ends of the first and second films and then forming a second seal adjacent behind the group of articles, and wherein the formation of the second seal forms a new first seal for a next-in-line group of articles to be bundled.5. The method according to claim 1, wherein shrinking the sleeve to form the bundle includes initially heating and cooling the sleeve.6. The method according to claim 1, further including the step of placing an identification code on the sleeve around the articles, the code identifying at least the type and number of articles in the bundle.7. A method of forming a single, separately identifiable bundle of articles comprising the steps of:providing a plurality of articles, each article bearing product information or advertising indicia on one or more surfaces thereof, and further having an individual identification code on a surface thereof;arranging the articles to form the bundle;wrapping the articles by placing a first film only partially around the plurality of articles such that the product information or advertising indicia on at least one article is at least partially viewable, and then wrapping a second dark-colored, opaque, or patterned film only partially around the plurality of articles so as to substantially obscure the individual identification codes on each of the articles; andat least partially securing the second film to the first film to form a sleeve around the articles, whereby the articles in the bundle may be identified from the product information or advertising indicia on the at least one article, but the obscuring prevents the automated scanner from reading the individual identification codes and identifying the bundle as a single article.8. The method of claim 7, wherein the first film is a transparent or clear film formed of a material selected from the group consisting of polyolefin film, polyvinyl chloride film, polyethylene film, polypropylene film, and cellophane.9. The method of claim 8, including shrinking the sleeve to substantially secure the articles in the bundle against movement relative to each other.10. The method of claim 9, wherein the first and second films are polyethylene films and shrinking the sleeve includes heating and cooling the sleeve.11. The method of claim 7, further including the step of applying a bundle identification code to the sleeve around the articles.
