Title:
FILM OF ETHYLENIC COPOLYMER
Document Type and Number:
Japanese Patent JP2574605
Kind Code:
B2
Abstract:
PURPOSE: To provide the subject film of an ethylenic copolymer excellent in mechanical and optical, blocking resistance and heat resistance properties and low-temperature heat sealability, etc., and having the various well-balanced excellent properties.
CONSTITUTION: The objective film of an ethylenic copolymer satisfies constituent requirements of ≤50 compositional distribution parameter (U) expressed by formula U=100×(Cw/Cn-1) (Cw denotes the weight-average branching degree; C denotes the number-average branching degree), a composition component having ≤2 branches/1000C branching degree accounting for ≤15wt.% of the ethylenic copolymer, a composition component having ≥30 branches/1000C branching degree accounting for ≤15wt.% of the ethylenic copolymer, etc.
