Bundling of containers

A container pack comprising:

• a first group of containers,
• a second group of containers, and
• a single planar substrate,
• wherein the first group of containers and the second group of containers each comprise at least one individual container, and
• wherein the at least one individual container of the first group of containers and the at least one individual container of the second group of containers, are bonded by means of at least one spot of hot melt adhesive to opposing sides of the single planar substrate, the single planar substrate located between the first group of containers and the second group of containers,
• wherein each spot of the hot melt adhesive, bonding the individual container of the first group of containers is on a different height than the spot of the hot melt adhesive on the opposite side of the single planar substrate, bonding the individual container of the second group of containers,
• the single planar substrate being perforated such that each spot of the hot melt adhesive on the single planar substrate is enclosed by a perforation line,
• a portion of the substrate within the perforated lines remains attached to the container once removed from the substrate.
