Multipackaging devices made of a resilient plastics-material such as low density polyethylene. The devices are made in strip form and are integrally interconnected longitudinally of the strip for continuous machine application to adjacent rows of containers with selective transverse severance of the applied strip to form individual packages of selected members of containers. The strip comprises a row of bands along each side thereof with intersecting and diagonally arranged substantially straight-line band segments extending between the side bands. The band segments cooperate with each other and with the side bands to define additional intermediate bands between the side bands. The strip is substantially narrower than the width of the rows of containers so that substantial transverse stretching of the strip is required to apply the side and intermediate bands to the rows of containers. In the strip the band segments cooperate with the side bands so that transverse stretching forces need only be applied to the side marginal edges of the strip to expand the strip for application to the rows of containers. That cooperation may be defined as resulting from an isotropic arrangement wherein upon application of stretching forces on either side of the strip an isotropic pattern of expansion occurs to give an unusual and unexpected result.
