Abstract: A thermoformable sheet includes an exterior film, a printed pigment layer, an adhesive layer, an inner layer, and an interior sealing layer. The exterior film includes between 50% and 100% polyolefin-based polymers, by weight. The inner layer includes between 60% and 100% of high-density polyethylene polymer, by weight. The inner layer further includes a thickness between 100 microns and 350 microns. The printed pigment layer and the adhesive layer are located between the exterior film and the inner layer.

Abstract: A retortable packaging film is disclosed. The retortable packaging film includes a laminate including a BOPP film and an MDOPP film. The retortable packaging film further includes a sealing layer disposed on the laminate. The sealing layer includes a blend including a polypropylene terpolymer and a long-chain branched polyethylene selected from the group consisting of LDPE and MDPE. The sealing layer has a melt flow index in a range of from 5 g/10 min to 25 g/10 min according to ASTM D1238 Procedure A Condition 230° C./2.16 kg. The retortable packaging film further includes a total composition including at least 80% polypropylene, by weight.

Abstract: Composite film (1) for closing a container (10) by sealing the composite film (1) against a circumferential sealing surface (11) of the container (10) or of a cap ring (12) to be connected to the container (10). The composite film (1) comprises an outer support layer (30) made of a metal film and an inner multilayer membrane (20) laminated to the outer support layer (30) using a bonding layer (28). The membrane (20) has a consecutive layer structure from the outside to the inside consisting of a backbone layer (21) made of polypropylene, an intermediate layer (23) made of a partially crystalline polyamide and a cohesively breakable peeling layer (25) made of polypropylene, polyethylene and talc, wherein between the intermediate layer (23) and the backbone layer (21) as well as between the intermediate layer (23) and the peeling layer (25) there is arranged a tie layer (22, 24) made of a maleic acid anhydride grafted polypropylene.

Abstract: A single-serve portion pack may have a multilayer film structure including a protective layer, a print, a base layer and a peelable seal layer. The print is situated in-between the protective layer and the base layer. The protective layer is a polyalkylene terephthalate based layer having a stress value at 20% strain, at 90° C., comprised between 5 and 20 MPa (preferably between 5 and 15 MPa), and a melting peak temperature comprised between 190 and 240° C. (preferably between 200 and 230° C.).

Abstract: A method for fabricating a micro- or nanofibrous filter is described. The method comprises obtaining at least a first carrier substrate, providing adhesive on at least a first carrier substrate, heating the adhesive above its melting temperature for inducing an interaction of at least part of the adhesive with the at least a first carrier substrate and then cooling below the melting temperature of the adhesive thus creating at least one adhesive carrier substrate. Thereafter, a layer of micro- or nanofibres is provided on the adhesive-side of the at least one adhesive carrier substrate to form a further structure. The further structure is then brought above the melting temperature of the adhesive for inducing an interaction between the adhesive and the micro- or nanofibres. Finally the temperature is again reduced below the melting temperature of the adhesive thus obtaining the micro- or nanofibrous filter.
