If the product is wrapped to unitize multiples, the ends may be left open with "bullseyes", and the film will be removed so that appearance is not a prime concern, Tekkra shrink bundling in a shrink polyethylene film is the logical choice.
If the package is required to be totally enclosed with no bullseyes but appearance is not critical, usually Texwrap shrink wrapping is the better choice. This style of wrapper is more naturally suited to producing fully-enclosed packages and can be faster and simpler especially for smaller packages
If the product is in cans, jars or bottles and is wrapped standing up- choose Texwrap if meant for display, Tekkra if meant to unitize.
If the product is in cans, jars or bottles and is wrapped standing and meant to unitize, supported in trays or unsupported
If the product is cans, jars or bottles and wrapped laying down, Texwrap shrink wrappers are the choice.
