どの欠点もあった。Conventionally, a method of producing a film is known in which a polyolefin resin containing filler is stretched to form voids inside and on the surface, making it white and opaque, and also giving the surface a paper-like luster. Stretched films with voids formed inside and on the surface, due to the presence of fillers and voids, are prone to peeling of the paper-like glossy surface layer due to abrasion during subsequent processing, such as abrasion during printing, printing, and optical reading. There were some drawbacks. In addition, when used as an adhesive laminate, if the adherend has an uneven surface, a flexible deformed surface, or a curved surface, it will have stiffness (Young's modulus is large) and will peel off from the adherend due to curling etc. There were also some drawbacks, such as:

なる擬紙化ポリオレフィンフィルムである。To provide a paper-like polyolefin film that does not peel off from an adherend consisting of a flexible deformable surface such as rubber, is prevented from being damaged by water, and is stable against changes in temperature and humidity. In order to achieve the above object, the present invention has the following configuration. That is, a stretched polyolefin film containing 10 to 40% by weight of filler (hereinafter referred to as "stretched polyolefin film containing filler"), and a film laminated on at least one side of this film and having a surface gloss of 30 or less and containing filler. Stretched polyolefin film (hereinafter referred to as "

The amount of filler added is 10-40-t%, preferably 15-35-t%. At less than 10 wt%,
White opacity cannot be obtained. On the other hand, if it exceeds 40 wt%, the film becomes brittle and cannot maintain mechanical strength, which is not preferable. Various additives such as a heat stabilizer, an antioxidant, a weathering agent, an antistatic agent, a nucleating agent, etc. may be added to the stretched polyolefin film l containing this filler.
