A plastic bag bundle is comprised of a plurality of juxtaposed flat plastic bags. Each bag has a front and rear wall panel and a mouth opening for inserting one or more articles in the bag. At least one flat article is retained captive in one of the front and rear panels. The bundle is formed of bags having the flat article in some of the bags disposed offset from the flat articles in others of the bags. The bags with the offset flat articles are interposed in a predetermined sequence with the others of the bags so as to form a bundle having a generally constant thickness in the area of the juxtaposed panels.

Why it's free to use
- Filed October 21, 1993 and granted May 8, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 21, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 21, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
