Abstract

A composite film includes a) a self-supporting layer of a polymer film (such as a polyester), b) an optional primer layer on the polymer film layer, wherein the primer layer includes a PVdX (X being halo), acrylic or vinyl resin; and c) a layer of heat seal composition on the primer layer, wherein the heat seal composition includes a polyolefin plastomer (POP) resin and a tackifier that constitutes at least 20 wt% of the heat seal composition. The composite film may be formed by applying a coating composition including the heat sea! composition in a solvent to a primer layer on the polymer film or directly on the polymer film in absence of the optional primer layer, and then evaporating the solvent. The composite film may be heat-sealed to a surface of a container or a self-supporting film.

Abstract

An interferometric method for profiling the topography of a sample surface, said method comprising the steps of: (i)a first interferometric profiling step in which a sample surface is analysed by single-frame interferometry (SFI) at a relatively low first magnification M1 to produce a map comprising pixels with planar (X,Y)-coordinates corresponding to the area of the sample surface, (ii)interrogating the pixel data obtained from the first profiling step by identifying pixel(s) which meet or exceed a Cut-Off Threshold, and which also meet or exceed a parameter N NAP which is the number of adjacent pixels all of which meet or exceed the Cut-Off Threshold; (iii)interrogating the pixel data obtained from the first profiling step by identifying pixel(s) for which no z-coordinate has been recorded; (iv)generating a Low Magnification Frame File (LMFF) which comprises the (X,Y) coordinates of the pixels derived from steps (ii) and (iii); (v)a second interferometric profiling step in which the sample surface is analysed at a relatively high second magnification M2, wherein M2>M1, wherein only selected regions of the sample surface are analysed at said second magnification M2, wherein said selected regions comprise the features associated with the (X,Y)-coordinates of the pixels in the Low Magnification Frame File; and further comprising a step selected from: (vi)the step of analysis of the output of the second interferometric profiling step to differentiate between an intrinsic defect and an extrinsic defect; (vii)the step of assessing whether said sample surface meets one or more quality control standard(s) and/or one or more target property or properties; and (viii)the step of assessing whether said sample surface is suitable as a surface for subsequent coating.

Abstract

A method of improving the flexibility of a coated polyester substrate for an electronic device comprising a coated polyester substrate layer and an electrode layer comprising conductive material, said method comprising: (a) providing a polyester film; and (b) disposing an organic/inorganic hybrid coating on one or both surfaces of said polyester film, wherein said coating is derived from a coating composition comprising a low molecular weight reactive component selected from monomeric acrylates and/or an unsaturated oligomeric component selected from acrylates, polyether acrylates, epoxy acrylates and polyester acrylates; a solvent; and inorganic particles, and optionally further comprising a photoinitiator.

Abstract

A method of preventing or minimizing the formation of haze in a biaxially oriented polyester film during the annealing of said film above its glass transition temperature, said method comprising: (a) selecting a biaxially oriented polyester film having glass transition temperature (Tg (° C.)); (b) disposing a coating on one or both surfaces of said biaxially oriented film; (c) annealing said coated biaxially oriented polyester film at a temperature above its glass transition temperature, wherein said coating composition is selected from: (i) an organic coating comprising a low molecular weight reactive diluent; an unsaturated oligomer; a solvent; and a photoinitiator; (ii) an organic/inorganic hybrid coating comprising a low molecular weight reactive component and/or an unsaturated oligomeric component; a solvent; and inorganic particles, and optionally further comprising a photoinitiator; (iii) a predominantly inorganic hardcoat comprising inorganic particles contained in a polymerisable predominantly inorganic matrix; and (iv) a composition comprising a cross-linkable organic polymer selected from polyethylene imine (PEI), polyester and polyinylalcohol (PVOH), and a cross-linking agent.

Abstract

A multilayer film suitable for sealing containers such as used for food packaging, and methods of making the film, are described. The film is particularly suitable for sealing containers made from polylactic acid (PLA). The multilayer film includes a) a substrate that includes a polymeric base layer; and b) on the substrate, a heatseal layer containing a PLA homopolymer or copolymer. The heatseal layer further includes dispersed therein an adhesion promoter, or alternatively the substrate further includes the adhesion promoter in a layer on a surface of the polymeric base layer between and adjacent the base layer and the heatseal layer. An antifog agent may also be included in the heatseal layer or on the surface of the heatseal layer opposite the substrate.
