An object of the present invention is to provide a multilayered polyamide-based tube for food packaging that is free from blocking in a Layer (C), and that has an excellent adherence to processed meat or like packaged food. The present invention provides a multilayered polyamide-based tube for food packaging comprising a Layer (A), a Layer (B) and a Layer (C);

Multilayered polyamide tube for food packaging

An anti-fogging, stretched, multilayer film comprising a layer having an anti-fogging agent incorporated therein, the film having evaluated values for anti-fogging property of 28 mmor more at temperatures of &#x2212;5&#xb0; C. and 15&#xb0; C., respectively.

Anti-fogging, stretched, multilayer film excellent in quick-acting property and method for producing the same

The present invention provides a multilayered polyamide film having at least two polyamide resin layers, which develops less than 10 pinholes when evaluated for pinhole resistance by flexing it 1,000-times at 25&deg; C. and which has an elongation of 6 mm or less at 120&deg; C. in vertical pitch evaluation. This film has excellent resistance to pinholes and is well suited for lamination.

Multilayered polyamide film with excellent processability

Low temperature heat shrinkable film for labels

A process for preparing a multilayer film having at least one polyamide layer include the steps of forcing out from a T-die by co-extrusion a multi-layer film having a layer containing about 50 to about 95% by weight of a crystalline polyamide and about 50 to about 5% by weight of an amorphous polyamide, and stretching the film at least in the lateral direction.

Process for preparation of multilayer films

The invention provides a multi-layer film having 1 to 4 polyamide layers, characterized in that at least one polyamide layer comprises about 50 to about 95% by weight of a crystalline polyamide and about 50 to about 5% by weight of an amorphous polyamide and that the multi-layer film is produced by stretching a flat film at least in the lateral direction; and a process for preparing the multi-layer film.
