BIODEGRADABLE WRAP FILM

摘要

A biodegradable wrap film simultaneously having not only the biodegradability of lactic acid resins but also cuttability, packaging capability and heat resistance. There has been developed a biodegradable wrap film composed mainly of a lactic acid resin composition, which biodegradable wrap film exhibits, as measured at a frequency of 10 Hz and a strain of 0.1% by the dynamic viscoelasticity measuring method according to the method of JIS K-7198 A, a storage modulus at 40°C of 100 MPa to 3 GPa and storage modulus at 100°C of 30 MPa to 500 MPa and exhibits a peak value of loss tangent (tandelta) of 0.1 to 0.8. This film excels in not only, suitable for use as a household wrap film, elasticity and softness and further elongation and tensile strength but also applicability to microwave ovens.
