Flexible polyimide multilayer laminates

The invention relates to laminates with layers of fully aromatic polyimides which are no longer shapable and are each bonded directly at one side to a layer of backing material.

The multilayer laminate thus obtained represents the basic body of the laminates according to the invention at the exterior surface(s) of which further layers can be joined. The laminates can be produced by a process which is also claimed in which heat-sealable polyimide or the precursor thereof is applied to polyimide which is no longer shapable, before or after it is completely cured. Subsequently the layers are bonded at elevated temperature, if appropriate after a curing stage. The backing materials are preferably metal or alloy foils. The resulting multilayer laminates are distinguished by outstanding mechanical, thermal and electrical properties. They can be used ...

Barrier Film for Use in Multilayer Thermoformable Materials and Shaped Articles and Containers Made Therefrom

The disclosure relates to a laminated, thermoformable barrier film useful as a peelable surface liner, such as in containers and other shaped articles. The laminated film includes at least two layers, including a distal layer and a medial layer. The medial layer includes an odor-resistant polymer barrier layer that inhibits passage of gases and odors therethrough. The distal layer includes a polymer layer that inhibits permeation of a liquid through to distal layer from a contact face thereof to the barrier layer. Optionally, the distal layer can include a scratch resistant layer. The laminated film can also include a proximal layer that includes a layer of a pliable polymer. The laminated film can be included as a surface liner, or stack of surface liners, on a thermoformed article or on a sheet that can be thermoformed. The laminated sheets have multiple uses, including as liners for food service containers. In such containers, the barrier layer of the laminated sheets can inhibit penetration of the liner by odors or tastes from food items contained therein and can also prevent liquid saturation of the barrier layer of the sheets, which could otherwise limit the odor-resistant properties of the sheets. 1. A laminated sheet suitable for use as a peelable liner on a thermoformed article for contacting an oily or aqueous liquid , the laminated sheet having a contact face and an adhesion face opposite the contact face and comprising at least medial and distal polymer sheets ,the medial sheet comprising a barrier layer of an odor-resistant polymer and having a proximal face and a distal face; comprising an anti-permeation polymer layer that substantially inhibits short-term permeation of the liquid therethrough,', 'bearing the contact face and having a first face opposite the contact face, and', 'having its first face bound to the distal face of the medial sheet by way of a first tie layer;, 'the distal sheet'}the contact face having a substantially lower surface ...
