Field of the Invention The present invention relates to an improvement of a cut line of a shrink film, and particularly, when it is used as a shrink tube (shrink label, cap seal, etc.), the bag is resistant to bag breakage and is attached to a bottle or the like. It is intended to prevent breakage of a tube originating from a cut line during time, a distribution process, etc. and to have a good cuttability required for separating the tube at the time of opening the bottle and after use.

されている。2. Description of the Related Art A shrink tube is a uniaxially stretched heat-shrinkable plastic film (shrink film) which is stretched in the circumferential direction of the tube and is widely used as a shrink label or a cap seal for containers such as bottles. Has been done. The shrink tube is generally provided with a cutoff line. The cut line is provided in a direction intersecting with the stretching direction of the film (the circumferential direction of the tube). FIG. 16 shows an example in which the shrink tube with cutoff line (2) is attached to the body of the bottle (3) as a label. The tube (2) in the figure is a single cutoff line
(In the example having (10), a tube in which two cut lines are formed in parallel and cut into a tape shape is also used.

FIG. 15 shows a perforation line formed as a perforation of the slit. The cutoff line of FIG. 7A has relatively long slits (17) at regular intervals (for example, slit length l 1 : gap l 2
= 3: 1), and the cut line in FIG. 6B has short slits (17) with a fine pitch (for example, l 1 , l 2 =
It is an example of being formed by 0.5 mm).

に必要である。The cutoff line (10) of the shrink tube is required to have resistance to bag breakage and good cuttability. The resistance to bag breakage is based on the cut line in the process of mounting to a bottle (heat shrinkage treatment of the tube with a steam heater etc.), the distribution process of the bottle with the tube (it may be impacted by transportation or dropping), etc. It is necessary to prevent the rupture, and the cuttability is necessary for opening the bottle and separating the label after the bottle is used (separate collection of bottle / label).

In the case of the cut-off line consisting of, it is difficult to satisfy both of the above characteristics at the same time even if the slit length, slit interval, pitch, etc. are adjusted as shown in FIGS. 15 (a) and 15 (b). For example, if the slit length is increased and the interval is decreased,
Cutability is improved, but bag breakage resistance is deteriorated. On the contrary, if the slits are shortened and the intervals are increased, the bag-breaking resistance is strengthened, but the cuttability is unavoidable, and horizontal tearing (shift in the cutting direction) is likely to occur during cutting, as shown in FIG.
It is difficult to cut the entire length of the tube. The same applies to the case where two tapes are provided and the tape is cut, and if the tape is pulled forcibly, the tape will be torn.

る。The holes (11) (12, 12 1 , 12 2 )
(13) and the like are not necessarily perfect circles. The holes formed by laser beam irradiation, which will be described later, may exhibit an elliptical shape (the ratio of major axis / minor axis is about 3 or less) slightly elongated in the scanning direction (perforation direction). In this case, the perforation may be designed with the pore diameter being the arithmetic average value of the major diameter (perforation direction) and the minor diameter (direction orthogonal to the perforation). Also, the numerical values of the above-mentioned specifications of the cutoff line slightly change due to heat shrinkage deformation when the tube is attached to the bottle (heat treatment),
For example, the pore size often expands. Therefore, the form of the cut line in the state of being attached to the container is slightly different from the above numerical value.

ことができる。The cut line of the present invention can be efficiently formed by laser beam irradiation. When a minute region on the film surface is irradiated with a laser beam, the irradiated minute region is instantly melted or evaporated to form holes (11) to (13) and a half cut (14). By scanning along the film surface while intermittently irradiating the laser, the above-mentioned FIG.
It is possible to form a perforation line composed of perforations shown in FIG.

取り線の形成に好適である。When the heat-shrinkable film stretched laterally uniaxially is intermittently irradiated with a laser in a direction intersecting with the stretching direction, cut lines (FIGS. 11) can be formed. The bank-shaped thick part (15) is formed in parallel with the formation of perforations.
It is considered that this is due to the effects of local heat shrinkage stress and surface tension near the perforations caused by the thermal effect of laser irradiation. The laser may be an argon laser, a YAG laser, etc., but a carbon dioxide laser is easy to obtain high energy,
Further, it is suitable for forming the perforation line of the present invention because it is easily absorbed by a polyester film or the like which is often used as a shrink tube.

れる。The shrink film (horizontal uniaxially stretched film) on which the cut line of the present invention is formed is not only a film uniaxially stretched in the horizontal direction of the film (circumferential direction of the tube to be formed) but also a bidirectional film in the horizontal / vertical direction. An axially stretched film, which can be regarded as a laterally uniaxially stretched film by a biaxial stretching ratio, is included. In this case, it is preferable that the stretching ratio in the horizontal direction is 2 times or more (for example, 2 to 7 times) in the vertical direction, and the stretching ratio in the vertical direction is about 1.5 or less. The heat shrinkage rate (horizontal direction) of the film is preferably about 30% or more (90 ° C. hot water × 10 seconds) in order to effectively form the bank-shaped thick part (15) in laser irradiation. Specific examples of the film having such physical properties include “Space Clean S7553” and “S clean 7075” (Toyobo Co., Ltd.).
