In recent years, crimes involving poisonous substances in the contents of food and medicine bottles, small boxes, etc. have occurred, and this has become a major social problem. To prevent this, cap reels, which cover the lid of the bottle or the entire container with heat-shrinkable film, and cap labels, which attach a label to the boundary between the lid and the main body to confirm that the bottle has not been opened, have come into use. 【came.

Problems with conventional techniques By the way, the cap reel or cap label mentioned above are both very effective in confirming that the package has not been opened.
The Ia layer is capped with a heat-shrinkable film, heated to a predetermined temperature by a heat source to be heat-shrinked, and coated tightly, resulting in high cost.

In the present invention, the resin composition used for film molding is polyethylene 10-90 having a density of 0.94097- or more.
It is a blend of % by weight and 10-90 g of polypropylene. Polyethylene is ethylene homopolymer,
A copolymer of ethylene and a different α-olefin, and a blend mainly composed of these 1. However, if the density is less than 0.940 g/cI71, the formed film will stretch and the cutting quality will be poor when used for Φ Yatsu plastic labels. If the blend ratio is less than 10% by weight, the tear strength of the polyolefin resin composition film when using a cap label will be strong, and the taste will be lower than 7-C5.
Mikai and Suuyu become difficult. Moreover, if it exceeds 90% by weight, the tear strength becomes too strong and the cutting quality becomes poor.

In addition, polypropylene includes propylene homopolymers, random copolymers and block copolymers of propylene and different α-olefins, and blends mainly composed of these, but the blend ratio of polypropylene is 1.
If it is less than 0% by weight, the tear strength of the polyolefin resin composition film when used as a cap label will be too strong, the cutting quality will be poor, and it will be difficult to put it into practical use. 9
If it exceeds 0% by weight, the cutting quality becomes poor for the same reason.

The Elmendorf tear strength is also affected by the take-off speed during film forming, but if the Elmendorf tear strength exceeds 2.0 kg/cr in the tear direction (direction of use), the cap label will be cut when the gong is opened. It tastes bad. Furthermore, if the dart impact exceeds 2.0/α, it becomes difficult to tear, but since the dart impact is approximately proportional to the thickness, even if the Elmendorf tear strength per unit thickness satisfies the above numerical limit, the tearing becomes difficult. Difficult to tear.
