Abstract: To provide a release film not to contaminate a mold or a molded article. The present invention provides a release film comprising, an oligomer bleeding prevention layer formed of an acrylic resin or a siloxane resin and laminated on a first face of a base layer that is formed of a polyethylene terephthalate resin; a surface layer formed of a fluororesin and laminated on the oligomer bleeding prevention layer; and a surface layer formed of a fluororesin and laminated on a second face of the base layer, or an oligomer bleeding prevention layer formed of an acrylic resin or a siloxane resin and laminated on a second face of the base layer, and a surface layer formed of a fluororesin and laminated on the oligomer bleeding prevention layer that is laminated on the second face.

Abstract: A flexible container in which a container body has a surrounding wall which is wove by a longitudinal thread and a lateral thread. As the longitudinal thread in a longitudinal strip range for stitching a hanging unit, a double-layer stretched tape yarn is used In which a first stretched tape yarn made of synthetic resin is covered by a second stretched tape yarn made of synthetic resin. As a longitudinal thread and a lateral thread other than a pair of strip reinforcing sections, the conventional stretched tape yarn made of synthetic resin is used. In the longitudinal strip area for stitching the hanging unit, the longitudinal thread having the double-layer stretched tape yarn is used, whereby it is possible to increase a count to reinforce the flexible container. The hanging unit has a base or proximal end thereof which is stitched to upper portions of the respective strip reinforcing sections by a sewing machine thread.
