Abstract

The present invention relates to a high barrier multilayer film for functional medical solution product comprising in order, an outer layer comprising polyethyleneterephthalate deposited inorganic oxide thereon; a first adhesive layer comprising ester type polyurethane; a first intermediate layer comprising ethylene vinyl alcohol copolymer; a second adhesive layer comprising ester type polyurethane; a second intermediate layer comprising polyamide; a third adhesive layer comprising ester type polyurethane; and an inner layer comprising propylene-based polymer. The multilayer film has the merits of improved transparency, heat resistance, sealing property, durability, competitive price, oxygen barrier property and less pinhole, so that may be applied to a outer bag of pouch type container of medical solution.

Description

technical field [0001] The present invention relates to a medical device that not only has high transparency, heat resistance, airtightness, durability, and cost competitiveness, but also has excellent oxygen barrier properties and small pinholes, and is suitable for medical use for dispensing water, blood, etc. It is a high barrier multilayer film for functional water liquid products that is packaged in the form of a pouch and used as the outer pouch of the water liquid container. Background technique [0002] Aqueous liquid containers (or plastic bags) used for packaging liquid medicines need to have properties such as flexibility, transparency, gas barrier properties, chemical suitability, sterilization heat resistance, heat sealability, and drop impact resistance. [0003] As the above-mentioned aqueous liquid container, a flexible (flexible) plastic container in the form of a bag having a plurality of (two or more) chambers is used. Functional liquid components that ma...
