本考案は、巻芯にストレツチフイルムを巻き付
けてなるロールフイルムに関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a roll film formed by winding a stretch film around a core.

わが入り易かつた。(Prior art and its problems) Stretch film is thin, elastic, and self-adhesive, and is used for stretch wrapping by stretching and wrapping raw meat, etc. on a tray, etc., with the edges adhesive. It has a strong character. A roll film in which this stretch film is wound around a core whose surface is made of decorative paper is susceptible to bending due to slipping between the starting end of the film and the surface of the core during winding, which affects the surface of the roll film and causes wrinkles. It was.

芯両端からせり出すという問題点があつた。 In addition, the winding core whose surface is covered with a polyethylene layer has good winding properties and does not cause wrinkles on the roll film surface, but as time passes, the winding force due to the elasticity of the film causes the winding core surface to There was a problem that slippage occurred between the polyethylene layer and the center of the stretch film, causing the core to protrude from both ends as shown by the dotted lines in FIG.

例を示す概略図である。 FIG. 1 is a sectional view showing an example of the rolled film of the present invention, FIG. 2 is a perspective view showing the structure of the winding core, and FIG. 3 is a schematic diagram showing an example of the method for forming the rolled film. .
本考案のロールフイルムは、第１図に示すとお
り、巻芯１にストレツチフイルム２を巻き付けて
なるロールフイルムにおいて、巻芯１の表面層１
１がストレツチフイルム２と同じ材質であること
を特徴とするロールフイルムである。 As shown in FIG. 1, the roll film of the present invention is a roll film in which a stretch film 2 is wound around a core 1, and the surface layer of the core 1 is
1 is a roll film characterized in that it is made of the same material as the stretch film 2.
すなわち、たとえばストレツチフイルム２が軟

なじみが良いから、巻き付け性が良くてストレツ
チフイルム始端に折り曲げを生ずることがなく、
ロール表面にしわを生ずることがない。また、巻
き付け後も互いになじむのですべらず、せり出し
を生ずることがない。 That is, for example, when the stretch film 2 is made of soft polyvinyl chloride, the surface layer 11 of the winding core 1 is also made of soft polyvinyl chloride, and when the stretch film 2 is made of ethylene-vinyl acetate copolymer resin, the surface layer 11 is also made of soft polyvinyl chloride. The surface layer 11 of the core is made of ethylene-vinyl acetate copolymer resin.
and stretch film 2 are made of the same material,
Because it blends in well, it has good winding properties and does not cause bending at the beginning of the stretch film.
Wrinkles do not occur on the roll surface. In addition, even after wrapping, they fit into each other, so they do not slip or protrude.
巻芯１を製造するには、たとえば第２図に示す
ようにあらかじめ軟質ポリ塩化ビニルフイルム等
の表面層１１を接着した化粧紙１２を芯層１３の
周囲にらせん状に巻き付けて表面層１１を形成す
ればよい。 To manufacture the winding core 1, for example, as shown in FIG. 2, a decorative paper 12 to which a surface layer 11 such as a soft polyvinyl chloride film has been adhered is spirally wound around a core layer 13 to form a surface layer 11. Just form it.

イルム端２１が速やかに巻き付き折り曲げが生じ
ない。 In order to form a roll film using this winding core 1, a normal method may be used. For example, as shown in FIG. The cutter 3 is moved horizontally in front of the cutter 3 to cut the stretch film 2 and bring the fallen film end 21 into contact with the rotating core to start winding. At this time, if the surface layer 11 of the winding core is made of decorative paper, the frictional force is weak, causing it to slip and sag, which is likely to cause bending. However, if the surface layer of the winding core is made of the same material as the stretch film 2, The cut film ends 21 are quickly wrapped around each other and no bending occurs.

外観の優れたものである。(Effects of the invention) Since the roll film of the present invention uses the same material as the stretch film for the surface layer of the core, wrinkles do not form on the roll surface, and the roll film does not protrude from both ends of the core over a long period of time. It has an extremely excellent appearance.
