A primer-less coating composition for facestock comprises: a binder being a water-dispersible polymer; an ethylenically unsaturated compound which is aqueous-dispersible and miscible with or bonded to said water-dispersible polymer, wherein said ethylenically unsaturated compound is able to form a covalent bond with an ink; and a crosslinker, wherein said crosslinker is suitable for binding the coating to the facestock. The coating composition may be applied to a substrate to form a printable film. A printed film in accordance with the invention may be used in a label, for example for use on a container such as a bottle.

Methods of authenticating a polymer film and devices to carry out the methods are described herein. The methods include measuring the birefringence of a layer of the film and determining if the film is authentic or otherwise based upon a birefringence measurement obtained in the measuring step. The birefringence measurement is indicative of a process of making the film and conditions of the process. The methods, and devices to carry out the methods, may be used in security applications, for example to test for counterfeit bank notes.

Abrégé

The invention is concerned with a naked collation package comprising an arrangement of individual packages, individually packaged in a polyolefinic filmic material, that are packed together in said naked collation package in a naked collation film, wherein the naked collation film comprises a sealable polyolefin film having a polyolefinic core layer C, an polyolefinic inner sealing layer A and a polyolefinic outer sealing layer B, the polyolefinic material of the inner sealing layer A being selected for sealing incompatibility with the filmic polyolefinic material of the individual packages under a specified sealing condition, and the polyolefinic material of the outer sealing layer B being selected for sealing compatibility with B and for sealing compatibility with A under the selected sealing condition, the individual packages being arranged in an ordered configuration inside the package and with the naked collation film wrapped around the ordered configuration of individual packages and sealed to itself (A to B) at a girth seal, and sealed to itself (B to B and optionally A to B) at envelope seals at each end of the package, there being no seal between the naked collation film and the filmic material of the individual packages.
