本発明は、ポリオレフィン樹脂系組成物により成形され
た易引裂性フィルムを用いたキャップラベルに関する。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a cap label using an easily tearable film formed from a polyolefin resin composition.
(従来技術)
近来、食品や薬品のビン、或いは小箱等の内容物に毒物

するキャップラベルが用いられるようになってきた。(Prior Art) In recent years, crimes have occurred in which poisonous substances are mixed into the contents of food and medicine bottles, small boxes, etc., and this has become a major social problem. To prevent this, cap stickers, 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, are being used. It has become.

点がある。(Problems with the prior art) By the way, both the cap seal and the cap label described above are extremely effective in confirming that the package has not been opened, but the former caps with a heat-shrinkable film and is heated to a predetermined temperature using a heat source. The cost is high because it is heated and heat-shrinked to cover tightly. Moreover, in the latter case, since the cap label is usually made of paper, it has the disadvantage that it discolors due to moisture or steam generated from the contents, which spoils the product image.
(発明の目的)
本発明は上記の事情に鑑み、耐水性、耐薬品性に優れ、

It is a film molded from a resin composition consisting of 0% by weight and 5 to 30% by weight of filler, and has a tart impact of 2Kg/cm or less and an Elmendorf tear strength of 2Kg/c layer or less in at least one direction. Features a cap label.

リマー。(Specific example of composition) In the resin composition used for film molding in the present invention, polypropylene may be a propylene homopolymer, a random copolymer of propylene and ethylene, a block copolymer of fluoropylene and ethylene, or a blend mainly composed of these. Yes, polyethylene is an ethylene homopolymer.

劣ってしまう、即ち両者の適度の併存により引裂のし易
さと切味の良さをもたらしている。Ethylene and heterogeneous α- such as butene-1 and hexene-1
Copolymers with olefins, blends mainly composed of these, etc., and if the density is less than 0.940g/crn' (JIS K6760), the sharpness of the cap label will be poor.6 Furthermore, if the content of both resins is 5. ~6
Even if it is less than 0% by weight, polyethylene is 30 to 90% by weight.
Even if the cap label is removed, it will be difficult to tear the cap label and the cutting quality will be poor.In other words, the moderate coexistence of both will result in ease of tearing and good cutting quality.
一方、充填剤は各樹脂は引裂し難い低流動性の場合でも

、炭カル、ワラストナイトが好ましく、また有機系とし
ては木粉、わらくず、ナイロンビーズなどが挙げられ。On the other hand, fillers are used to further improve tearability and sharpness even when the resin has low fluidity and is difficult to tear.Inorganic fillers include talc, charcoal, wollastonite, glass peas, and glass. Examples include fiber, clay, barium sulfate, white carbon, mica, etc., among which mica, charcoal, and wollastonite are preferred, and organic materials include wood flour, straw waste, nylon beads, etc.
5重量%未満では切味の向上効果が不足し、30重竜%
を越えるとフィルムの成形が不安定になり勝ちである。If it is less than 5% by weight, the sharpness improvement effect will be insufficient, and if it is less than 30% by weight.
If it exceeds this value, the film will become unstable.
また充填剤の粒度は、平均粒度0.01〜35JLmが

ルムの安定成形が困難となる。In addition, the particle size of the filler is preferably an average particle size of 0.01 to 35 JLm, and if it is less than 0.0 ip, m, it will be difficult to disperse in the composition and cause aggregation, and the aggregation will cause pores during film forming. Moreover, if it exceeds 35 ILrn, stable molding of the film becomes difficult.

ると引裂が困難となる。In addition, the formed film is a dirt impact (JIS-
Z-1702) must be 2.0 Kg @am or less, Elmendorf tear strength (ASTM-D-1709-75) must be 2.0 Kg/C or less in at least one direction, and the tear direction during use must be 2.0Kg in
/cm or less. Dirt impact is 2.0Kg・c
If the thickness exceeds at, tearing becomes difficult, and since the dart impact is approximately proportional to the thickness, even if the Elmendorf tear strength per unit thickness satisfies the above numerical limit, tearing becomes difficult as the thickness increases.

適なものとなる。In other words, a cap label made from a film formed using the resin composition so that the dart impact and Elmendorf tear strengths fall within the above ranges can be easily torn when opened, has a good sharpness, and has a polyolefin resin composition. Therefore, it has excellent water resistance and chemical resistance, and cannot be opened without damaging the label, making it suitable for checking whether the package has been opened.

Using a resin composition, the thickness was 30 pm (only Comparative Example 7 was 90 pm).

The cap label was attached to a 100 m long plastic bottle 2 so that the edge 4 of the cap 3 was parallel to the MD, and the cap label was twisted to compare the sharpness of the cap label.
