Patent ID: 11801671

Abstract:
This present invention relates to a method for making a two-layered product (3) comprising a hydrophilic first material (1) made from electrospun fibers connected to a hydrophobic second material (2) made from electrospun fibers, and wherein said first material (1) contains a drug substance, characterized in that —said method comprises using a press (5) comprising a first surface (100) and a second surface (200), and wherein said second surface (200) has a temperature being higher than the temperature of said first surface (100), —said first (1) and second material (2) being arranged in a layered combination between the first (100) and second surface (200) of the press (5), wherein a pressure is provided towards said layered combination from said first (100) and second surface (200) of said press (5), and whereby said first material (1) comes into contact with said first surface (100) of said press (5), —wherein the combination of pressure between the first (100) and second surface (200) and the temperature of said second material (2) connects said first (1) and second material (2) into said two-layered product (3).
