Title:
ETHYLENE RESIN COMPOSITION AND FILM
Document Type and Number:
WIPO Patent Application WO/2021/200991
Kind Code:
A1
Abstract:
According to the present invention, an ethylene resin composition which satisfies the requirements (1) to (4) as a material for packaging materials and the like enables the achievement of a film that has an excellent balance between the strength for protecting the contents and the stiffness (openability upon filling of the contents into a packaging material, free-standing properties and the like). (1) The melt flow rate (at 190°C under a load of 2.16 kg) is from 0.1 g/10 min to 1.0 g/10 min. (2) The density is from 915 kg/m3 to 935 kg/m3. (3) The melt index (I21 at 190˚C under a load of 2.16 kg) is 45 or less. (4) The ratio of the amount of melting heat (Hh) as determined from the DSC curve at 120°C or higher to the total amount of melting heat (Ht) as determined from the DSC curve of the DSC measurement, namely, the amount of melting heat ratio (Hh/Ht) at 120°C or higher is from 10% to 55%.
