Claims10
A biocompatible film comprising a first outer layer containing a biopolymer, an inner layer containing a biopolymer, and a first bonding layer disposed between the first outer layer and the inner layer to bond the first outer layer and the inner layer wherein the first bonding layer contains components derived from the first outer layer and components derived from the inner layer.
A method for producing a biocompatible film, comprising:
- primarily semi-drying a first outer layer-forming solution containing a biopolymer dissolved therein to form a first outer gel layer;
- introducing an inner layer-forming solution containing a biopolymer dissolved therein onto the first outer gel layer and secondarily semi-drying the inner layer-forming solution to form an inner gel layer;
- and introducing a second outer layer-forming solution containing a biopolymer dissolved therein onto the inner gel layer and completely drying the second outer layer-forming solution to form a laminate in which a first outer layer, a first bonding layer, an inner layer, a second bonding layer, and a second outer layer are sequentially formed.
