摘要： The present invention provides a high quality laminated sheet material prepared using as much materials of biological origin as possible in order to contribute to the prevention of deterioration of the environment and provide a reduction in the amount of exhaustible resources being consumed. The laminated sheet material of the present invention is characterized by having at least one first layer and at least two different kinds of layers selected from the group consisting of a second layer, a third layer and a fourth layer, wherein the first layer has a resin composition A which includes a polyester resin (a) containing 25% or more of a component of biological origin and a polyolefin resin (b); the second layer has as the main component the polyester resin (a) containing 25% or more of a component of biological origin; the third layer has as the main component the polyolefin resin (b); and the fourth layer has as the main component an adhesive resin (c).

摘要： There is provided a packaging film which has a good suitability for use in an automatic packaging machine, and is free from occurrence of sagging even when stored in a low-temperature condition for a long period of time as well as hardly suffers from occurrence of whitening when subjected to high stretch packaging. The stretch packaging film of the present invention comprises a laminated film having at least three layers comprising opposite surface layers each comprising an ethylene-based resin (A) as a main component and an intermediate layer comprising a propylene-based resin (C) and a propylene-based resin (B) which respectively satisfy specific conditions, at a specific compounding ratio, and having a heat of crystallization (”Hc) of 10 to 60 J/g as measured at a temperature drop rate of 10°C/min using a differential scanning calorimeter (DSC) and a storage elastic modulus (E') at 20°C of 100 MPa to 1 GPa as measured with respect to the laminated film at an oscillation frequency of 10 Hz and a distortion of 0.1% by a dynamic viscoelasticity measuring method.
