A tube comprising a first channel and a second channel wherein each of said first and second channels extends along the longitudinal axis of said tube, and wherein said tube is constituted by a first heat-sealable polymeric film A and a second heat-sealable polymeric film B. Said polymeric films A and B each have a first surface (A1, B1) and a second heat-sealable surface (A2, B2) respectively. Polymeric films A and B are disposed such that said heat-sealable surfaces A2 and B2 are in contact with and adhered to each other by heat-seal bonds which do not extend across the full surface area of said heat-sealable surfaces A2 and B2. Also described are methods of making the tube, a kit comprising a plurality of polymeric films for forming the tube, and methods for using the tube in the delivery of injectable chemicals.

A recycling-friendly, easily producible paper packaging laminate with a high barrier against water vapor, oxygen and/or aromas, wherein a barrier film includes at least one substrate layer, a joining layer, and a barrier layer, wherein the joining layer is arranged between the substrate layer and the barrier layer, in that the substrate layer consists predominantly of polyethylene or polypropylene with a polyethylene content or a polypropylene content of at least 60 wt. % of the substrate layer, in that at least the at least one substrate layer of the barrier film is stretched, in that the content of the paper layer is between 50 wt. % and 90 wt. % of the paper packaging laminate, and in that the barrier film is joined to the paper layer by a hydrophilic adhesive layer, wherein the side of the paper layer facing the barrier film is uncoated.

The present invention relates to a transparent, peelable polyester film incorporating at least one biaxially oriented polyester film (=base layer (B)) and at least one peelable covering layer (A) coated offline thereon, in which the covering layer (A) is at least 85 wt. % made up of a polyester of aromatic and aliphatic dicarboxylic acids and aliphatic diols, and the arithmetic mean value of the absolute ordinate values S.sub.b of the covering layer (A) is less than 300 nm and the reduced peak height S.sub.pk of the covering layer (A) is less than 700 nm. The invention further relates to a production process for this peelable film and use thereof as sealing film for APET and/or RPET meal trays.

The present disclosure provides a composition containing a polymeric blend. The polymeric blend contains (A) from 50 wt % to 90 wt % of a first ethylene-based polymer having a density from 0.895 g/cc to 0.905 g/cc; and a melt index from 0.1 g/10 min to 50 g/10 min; (B) from 8 wt % to 48 wt % of a second ethylene-based polymer having a density from 0.935 g/cc to 0.967 g/cc; and a melt index from 0.1 g/10 min to 180 g/10 min; and from 0.01 wt % to 2.0 wt % of a slip agent, based on the total weight of the polymeric blend. The polymeric blend has (i) an overall density from 0.900 g/cc to 0.925 g/cc; and (ii) a coefficient of friction (COF) after aging for 1 week at 60° C. from 0.001 to 0.400. The present disclosure also provides a multilayer film with a first layer containing the composition.

A plastic film composite for film packaging with an oriented outer film and a sealing film which differs from the outer film, both of which outer film and sealing film are either polyethylene-based or polypropylene-based. The outer film and the sealing film are connected by a polyolefin-based extrusion lamination comprising at least one layer. A film packaging comprising the plastic film lamination and a method for the production of packaging containers uses the plastic film composite.

The present invention is directed to a monoaxially oriented multilayer film suitable for shrink lidding applications.
