Open the CIPO recordAbstract From the Canadian patent
A shrink wrapping for articles e. g. bottles, is so constructed that it includes a carrier handle. The articles are placed between two webs of shrinkable plastics sheet material such that the articles are enwrapped by the webs at one end of the group of articles and across two opposite faces of the group. A lateral band is formed out of the webs at the other end of the group by laterally heat sealing the webs together so that the group then is fully surrounded in at least one direction by those portions of the webs not forming the band. The webs then are shrunk fit to the articles.
