A method for the production of an elastic laminate, with the following steps in a production line: coextrudeing a first web of elastic film with at least three layers, with at least two different polymer materials, to feed contemporaneously said coextruded first elastic film web and two second nonwoven webs to a thermal, binding calender, wherein the first elastic film web is arranged between said two second nonwoven webs when entering the calender; wherein said first elastic film web, during the movement from the coextrusion step to the thermal binding step, passes from a melted state, to a solidified and cold state when entering the calender, to join, through spot welding in said calender, said second nonwoven webs with respective opposite outer layers of said first elastic film web, thus producing an intermediate web, to stretch mechanically said intermediate web according to a direction transverse to the same web.

The invention relates to multilayer film and the use of said film as a part of a FIBC construction.

The invention relates to a metallocene complex according to formula (I), (I) wherein R.sub.1 and R.sub.2 are independently selected from H, an alkyl or an aryl group, wherein R.sub.3 is a C1-C10 alkyl group, wherein R′ is selected from H, an alkyl group, an aryl group and wherein different R′ substituents can be connected to form a ring structure and wherein B is a 1,2 phenylene bridging moiety, which can be optionally substituted, wherein Mt is selected from Ti, Zr and Hf, X is an anionic ligand, z is the number of X groups and equals the valence of Mt minus 2. The invention also relates to a catalyst comprising the reaction product of the metallocene complex and a cocatalyst. Further the invention relates to a (co)polymerisation process of olefinic monomers.

A polyethylene-based composition may include an ethylene-based copolymer produced from ethylene and one or more C3-C10 alpha olefin comonomers, wherein the ethylene-based copolymer has: a density ranging from 945 kg/m.sup.3 to 961 kg/m.sup.3 according to ASTM D792, a melt flow rate (MFR.sub.2) ranging from 0.5 g/10 min to 3.0 g/10 min according to ASTM D1238 at 190° C./2.16 kg, a molecular weight distribution (Mw/Mn) ranging from 3 to 25, and a stress exponent (SEx) ranging from 1.0 to 1.8.

Provided is a laminate including a base material layer, an adhesive layer having a thickness in a range of 0.1 μm to 1.0 μm, and a non-oriented sealant layer having a thickness in a range of 10 μm to 40 μm and made of a cyclic polyolefin resin, wherein one main surface of the sealant layer constitutes an outermost surface of the laminate, the other main surface of the sealant layer is bonded to the base material layer via the adhesive layer, and an adhesion strength between the base material layer and the sealant layer is 0.8 N/15 mm or more.

This invention relates to a process for reducing or eliminating organoleptic degradation in organoleptically sensitive foods packaged in flexible packaging, and packaged products thereof. This invention also relates to organoleptic flexible packaging made from polymeric films comprising oxidation-stable and non-migratory polysiloxane as slip additive. The oxidative-stability and non-migratory nature of the polysiloxane slip additive provides an organoleptic flexible packaging that is non-interactive with and inert to the organoleptically sensitive food packaged within, specifically: (1) coffee; (2) beer; (3) water; and (4) wine.

A carbon nanotube sheet structure includes: a carbon nanotube sheet; a first base material including a first base material surface facing the carbon nanotube sheet; and a first spacer providing a gap between the carbon nanotube sheet and the first base material. A first base material surface of the first base material includes a first region on which the first spacer is provided and a second region on which the first spacer is not provided. The first base material is spaced apart from the carbon nanotube sheet at the second region on the first base material surface.

Described herein are physically crosslinked, closed cell continuous multilayer foam structures that includes a foam layer comprising polypropylene, polyethylene, or a combination of polypropylene and polyethylene and a polyamide cap layer. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one foam composition layer and at least one cap composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.
