Document Type and Number:
WIPO Patent Application WO/2023/166995
Kind Code:
A1
Abstract:
The present invention relates to a multilayer film for ultrasonic sealing and a package. Provided is a multilayer film for ultrasonic sealing, the multilayer film comprising at least a thermoplastic resin layer containing a thermoplastic resin, and a sealing layer containing a linear low-density polyethylene and an α-olefin resin, the α-olefin resin containing a butene-based α-olefin resin, and the multilayer film being capable of sealing by ultrasonic waves. Thus, the multilayer film for ultrasonic sealing is applicable to mono-materialization, is such that ultrasonic welding is possible, has sufficient rigidity, has a narrow sealing width, and is capable of having uniform and stable ultrasonic sealing strength.
