Title:
RESIN COMPOSITION, FILM, MULTILAYER BODY AND PACKAGING BAG FOR MEDICAL USE
Document Type and Number:
WIPO Patent Application WO/2020/170935
Kind Code:
A1
Abstract:
A resin composition which contains (A) an ethylene-vinyl acetate copolymer and (B) a propylene resin, and which is characterized in that: the melt flow rate (MFR at 190°C under a load of 2.16 kg), namely MFR (A) of the ethylene-vinyl acetate copolymer (A) and the melt flow rate (MFR at 190°C under a load of 2.16 kg), namely MFR (B) of the propylene resin (B) satisfy the relational expression (i) described below; the resin composition has an endothermic peak at 120-170°C as determined by differential scanning calorimetry (DSC); and the melting enthalpy at 120-170°C is 15-40 mJ/mg.　(i): 4 g/10 minutes ≤ MFR (A) – MFR (B) ≤ 35 g/10 minutes
