Packaging and labelling films

The present invention provides a transparent, dimensionally stable, biaxially oriented pla film having a haze value of less than 3% and exhibiting strain induced crystallinity having been oriented by stretching the film from a substantially non-crystalline state by more than three times its original areal dimensions. The processes for making such films are also disclosed.. ... Innovia Films Limited

Polyvinylidene chloride coated substrates

The present invention concerns a coated substrate comprising a substrate and an extrusion coated pvdc layer with a thickness of less than 10 micrometres.. . ... Innovia Films Limited

Authentication apparatus and method

An authentication apparatus operative to determine the authenticity of an item comprising a film substrate responsive to detection that a portion of said item located in a measuring region of said apparatus has a predetermined birefringence characteristic, said apparatus comprising: an item detection arrangement operative to determine if at least a portion of an item is located in a measuring region of said authentication apparatus; and an optically-based birefringence measuring apparatus, wherein said authentication apparatus is operative to compare a measured birefringence characteristic with a predetermined birefringence characteristic and to produce an authenticity signal indicative of authenticity or otherwise of said item based upon said comparison, said apparatus further comprising a control means operative to control output of said authenticity signal from said apparatus responsive to determination, by said item detection arrangement, of presence or otherwise of said at least a portion of said item in said measuring region.. . ... Innovia Films Limited

Authentication apparatus and method

The present invention provides an authentication apparatus operative to determine the authenticity of a polymer film, comprising an optically-based birefringence measuring arrangement operative to measure a first effect influenced by a birefringence characteristic of said film from a first angle comprising a non-normal angle to a plane of said film, and at least one of: a second angle; and a third angle; and wherein said apparatus is operative to: compare a value, or range of values, representative of said first effect as measured from said first angle with a value, or range of values representative of a specified first effect corresponding to a predetermined birefringence characteristic of an authentic polymer film for said first angle; compare a value, or range of values, representative of said first effect as measured from said at least one of said second and third angles with a value, or range of values representative of a specified first effect corresponding to a predetermined birefringence characteristic of an authentic polymer film for respective second and/or third angles; and output an authenticity signal indicative of authenticity or otherwise of said film based upon said comparisons. There are also provided one or more methods of determining the authenticity of a polymer film.. ... Innovia Films Limited

Authentication apparatus and method

The present invention provides an authentication apparatus operative to determine the authenticity of a polymer film, comprising: an optical response modifier operative to modify a first effect influenced by said birefringence characteristic of said to a modified first effect; and an optically-based birefringence measuring arrangement operative to measure said modified first effect; and wherein said apparatus is operative to: compare a value, or range of values, representative of said modified first effect as measured with a value, or range of values representative of a specified first effect as modified by a same optical response modifier and corresponding to a predetermined birefringence characteristic of an authentic polymer film; and output an authenticity signal indicative of authenticity or otherwise of said film based upon said comparison. There are also provided one or more methods of determining the authenticity of a polymer film.. ... Innovia Films Limited

Authentication apparatus and method

The present invention provides an authentication apparatus operative to determine the authenticity of a polymer film, comprising an optically-based measuring arrangement operative to measure a first effect influenced by a birefringence characteristic of said film and a second effect influenced by another optical characteristic of said film, and wherein said apparatus is operative to: compare a value, or range of values, representative of said first effect with a value, or range of values representative of a specified first effect corresponding to a predetermined birefringence characteristic of an authentic polymer film; compare a value, or range of values, representative of said second effect with a value, or range of values representative of a specified second effect corresponding to a predetermined other optical characteristic of an authentic polymer film; and output an authenticity signal indicative of authenticity or otherwise of said film based upon one or both of said comparisons. There are also provided one or more methods of determining the authenticity of a polymer film.. ... Innovia Films Limited

Printable film

This invention concerns a process for producing a food contact approvable, printable film comprising: providing a web of film having a width of at least about 1 cm and/or a length of at least 1 m and/or a weight of at least about 1 g and having a food-contactable surface; at a first location subjecting at least a first surface of the film web to a modified atmosphere dielectric barrier discharge (madbd) treatment; winding the film web onto a reel; transporting the wound film web to a second location; unwinding the film web from the reel; and subjecting the first surface of the film to corona treatment. The invention also concerns printed films obtainable by the process of the invention, and articles of packaging and/or labelling made from such films.. ... Innovia Films Limited
