縮時にカールして体裁が悪くなるという欠点があった。Figure 1 shows an example of conventional packaging, but since the shrink label film 02 used to package the bottle O1 cannot be bonded using normal heat sealing methods or has problems with adhesive strength, ultrasonic or high frequency sealing methods are used. has been adopted. In the case of such ultrasonic or high-frequency seals, there is a risk that if the seal part comes off the overlapped part, the film will be perforated or melted, so leave a small part of the overlapped part. A method of sealing is used. As a result, the unsealed portion is 03.0
3' becomes a fold and remains on the surface or inside of the label, and it curls during heat shrinkage, resulting in an unsightly appearance.

り取るものである。The present invention proposes a plastic film bag making method that does not have such drawbacks, and in which both lengthwise ends of plastic shrink label films are pulled together and overlapped, and when envelope pasting is carried out using ultrasonic or high frequency waves, the lower side is Apply adhesive in advance to the upper surface of the edge of the plastic shrink label film that is to be placed, and at the same time as sealing with ultrasonic waves or high frequency, or before or after sealing, adhere this adhesive-applied part and seal the upper side. The end portion outside the seal interface is cut off at the same time as sealing or after sealing.

る。FIG. 2 shows an embodiment of the present invention, in which 1 is a shrink label film, and the shrink label film 1 is formed into a cylindrical shape by pulling its longitudinal ends 2.3 together and overlapping them. Ultrasonic sealing 4 is performed approximately in the middle of this overlapped portion, and the adhesive 5 portion on the upper surface of the inner end 3 that has been applied in advance is pressed and bonded at the same time as high frequency sealing 4, and then, The edge 2 of the overlapping shrink label film 1 located on the upper side is cut along the longitudinal direction from the sealing interface to eliminate the portion remaining as folds on the surface.

時に行なうようにしてもよい。In addition, an ultrasonic sealing method may be used as the sealing method.
Further, the adhesive 5 portion may be bonded after or before high frequency sealing, and the end 2 may be cut off at the same time as high frequency sealing 4.

ムが熱収縮しても外観を損なうことがない。The method of the present invention is as described in -1- below, in which shrink label films are brought together by pulling together both ends in the longitudinal direction and overlapping.
When pasting envelopes using ultrasonic or high-frequency waves, the inner unsealed part is glued with adhesive to prevent folds from remaining, and the outer edge is cut away from the sealing interface. Therefore, even if the shrink label film shrinks due to heat, the appearance will not be damaged.
