摘要:
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.
摘要:
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° C. and which has an elongation of 6 mm or less at 120° C. in vertical pitch evaluation. This film has excellent resistance to pinholes and is well suited for lamination.
