2. Description of the Related Art Conventionally, various polyethylene-based pressure-sensitive adhesive labels have been known (for example, JP-T-62-50017).
No. 7). However, conventional adhesive labels such as the label disclosed in JP-T-62-500177 have extremely low tensile strength after printing of a polyethylene film to be used. When affixed to a material, the label may not be able to follow the elongation of the base material and the label may be damaged. In addition, since the rigidity is low, various problems occur when performing automatic labeling. Furthermore, many conventional polyethylene films have poor gloss, and when such a film is printed, the appearance of the printed surface is impaired, and the product value as a label is extremely reduced. Further, in the case of a film with poor transparency, if the printing is not performed on the entire surface, the background of the unprinted film portion is conspicuous, and the appearance of the product as a label deteriorates.

Therefore, at present, a polyethylene-based pressure-sensitive adhesive label can be printed and has a tensile strength that follows the elongation of a substrate to be stuck even after printing. There is a demand for an adhesive label film which is hardly damaged, has no trouble even by automatic labeling, and has good print appearance.

[0006] When the density is less than 0.925 g / cm 3 , the rigidity is reduced and a trouble may occur during labeling. Conversely, if it exceeds 0.945 g / cm 3 , transparency often deteriorates. When the MFR is less than 0.1 g / 10 minutes, the transparency becomes poor and the film formation becomes difficult. When the MFR exceeds 4 g / 10 minutes,
The tensile strength after printing is low, which may cause trouble after labeling. Further, when the molecular weight distribution exceeds 7, the optical properties (gloss, transparency) of the film are reduced,
Decrease product value. Incidentally, polyethylene having a molecular weight distribution of less than 3 is not practical because it is usually difficult to produce.

In general, in order to make the film of the present invention an adhesive label, for example, an adhesive may be applied directly. However, generally, a release agent such as silicone is applied to a supporting sheet such as paper and cured. Then, an adhesive layer is applied thereon using a knife coater or the like, and the film is further laminated thereon by passing through a nip roll or the like and adhered thereto. After that, printing is performed on one side of the film, usually in the label punching process,
It is supplied to the market through processes such as an automatic labeling process.

Next, the present invention will be described in more detail with reference to Examples and Comparative Examples. Example 1 Using an inflation film molding machine having a diameter of 55 mm, a density of 0.930 g / cm 3 , an MFR of 1.0 g / 10 minutes,
An 80 μm thick film was formed from low-density polyethylene having a Mw / Mn of 5.3. Table 1 shows the tensile strength, Young's modulus, haze and gloss of this film. After performing a corona treatment on this film, an acrylic pressure-sensitive adhesive was applied, and a release paper was further laminated. Further, after performing corona treatment on the surface of the film, printing was performed. Next, the printed portion of the film on which the release paper was laminated was punched (label punching). The label created by punching was adhered to the container using an automatic adhering device (trade name: Automatic Labeler MD-1 manufactured by Lintec Co., Ltd.) (automatic labeling). Table 1 shows the evaluation results on the embrittlement and flexibility of the label after printing and punching on the label (the ability of the label to follow the base material) and the operability during automatic labeling. In addition, the tensile strength is JIS
According to Z 1702, Young's modulus is ASTM D781
, The haze was measured according to JIS K7105, and the gloss was measured according to JIS K7105.
