The present invention provides a method for forming a naked collation package wherein a naked collation film is rendered incompatible for sealing purposes at a sealing condition with a polyolefinic material wrapping individual packages, the naked collation film having A to B, A to A and/or B to B sealing compatibility with itself at the sealing condition but being sealingly incompatible at the sealing condition with the filmic polyolefinic material of the individually wrapped packages, the sealing incompatibility being provided by providing in at least an inner sealing layer of the naked collation film at least one polyolefinic material derived from a monomer of different chain length from a monomer from which at least one polyolefinic material in the filmic material of the wrapped individual packages is derived. |
