A barrier film laminate (1) comprising an organic layer (4) that is situated in between two inorganic layers (2,3). The organic layer comprises submicron getter particles (5) at an amount between 0.01 and 0.9% by weight. The barrier film laminate can be used for encapsulating organic electronic devices such as OLEDs. The long term homogenous transparency makes this laminate in particular suited for protecting the light emitting side of an OLED.

The present invention is a laminate film comprising a plastic film, and an inorganic layer and an organic layer containing a 1,3,5-triazine derivative laid on at least one surface of the plastic film, wherein the 1,3,5-triazine derivative has a sulfur-containing group as a substituent on at least one of 2, 4 and 6 positions.

There are provided an inorganic film in which the light transmittance is not decreased also when the inorganic film is laminated on organic material such as a resin, and a laminate. An inorganic film 13 which comprises a refractive index gradient film 13a having a refractive index changing continuously from n1 to n2 (n1<n2) and being a functional film; and a refractive index gradient film 13b having a refractive index changing continuously from n3 to n4 (n4<n3) and being a functional film, and in which further, a difference between n2 and n3 is 0.1 or less.

A laminated polypropylene-based film suitable for retort packaging having an exterior film, a barrier layer, and a sealing layer. The retort packaging film has a total composition including high levels of polyolefin-based polymers and polypropylene-based polymers such that the material can be processed efficiently in a polypropylene recycling process. Advantageously, the film retains the properties required to suitably withstand the retort process and produce a high-quality shelf-stable packaged product.
