Description

  The present invention relates to a packaging material capable of easily opening a heat-shrinkable film packaging an object to be packaged.

  Since packaging materials that use heat-shrinkable film cannot be restored to their original packaging once opened, self-service counters are used to ensure that the products are not used and to prevent mischief. Widely used in packaging of goods for sale on display.

However, a packaging material using such a heat-shrinkable film is not easy to open because it is in close contact with the package. Therefore, in order to facilitate the opening, conventionally, a cut tape is stretched over the back surface of the heat-shrinkable film and fused, the opening ear piece of the cut tape is projected, and the opening ear piece is pulled to cut it. What tears a heat-shrinkable film with the tape was employ | adopted (refer patent document 1, 2). However, this is because the opening ear piece protrudes, and when it is displayed on top of the display shelf, the opening ear piece touches another product when it is displayed or lowered from the shelf, and the cut tape is pulled and the heat shrinkable There is a problem that the product is damaged by tearing the film and damaging the packaging.
Japanese Patent Laid-Open No. 8-282732 Japanese Patent Laid-Open No. 9-24970

  The present invention solves the conventional problems as described above, and the packaging by the heat-shrinkable film is not damaged even if it is touched with another product when displaying from the shelf or being removed from the shelf, and it is easy and safe. A packaging material that can be opened is provided.

  The packaging material of the present invention is formed by forming a polymerized portion in which a reinforcing tape made of a non-heat-shrinkable film material is pasted on at least one of the front and back surfaces of a heat-shrinkable film that wraps an article to be packaged. A basic invention is characterized by providing a notch that crosses the line.

  And in the said invention, it is preferable to provide the extended notch part along the both sides of the superposition | polymerization part in the both ends of a notch, and to make it a gate shape. Further, it is more preferable to leave a connecting portion between the cut and the extended cut portion. The reinforcing tape made of a non-heat-shrinkable film material is preferably made of cellophane or polyethylene terephthalate.

  Furthermore, a reinforcing tape made of a non-heat-shrinkable film material may be attached to the back surface of the heat-shrinkable film as a polymerized portion, or the surface of the heat-shrinkable film may be non-heated. Applying a reinforcing tape made of a shrinkable film material as a polymerization part, or attaching a reinforcing tape made of a non-heat-shrinkable film material on both the front and back surfaces of a heat-shrinkable film as a polymerization part Good.

  The packaging material of the present invention is formed by forming a polymerized portion in which a reinforcing tape made of a non-heat-shrinkable film material is attached to at least one of the front and back surfaces of a heat-shrinkable film that wraps an article to be packaged. Since the cut portion is provided with a reinforcing tape made of a non-heat-shrinkable film material on the heat-shrinkable film, the packaged item is provided. The product will not shrink even if it is heat-shrinked after storage, so the cut will not spread, and there is no risk of other objects getting caught in this cut, so the product will be damaged when the product is displayed or taken out. There is no loss of value.

  Thus, when opening, if the surface of the overlapped portion is pulled while pressing with a finger, a frictional force acts between the finger and the overlapped portion and slides from the notch, and the strong overlapped portion and its Since the boundary is cut and the heat-shrinkable film is peeled off at the width of the polymerized portion, the heat-shrinkable film can be easily removed and opened.

  In addition, if extended notches are provided at both ends of the incision along both sides of the overlapping portion to form a portal shape, the surface of the overlapping portion is pressed with a finger and slid from the notch to the width of the overlapping portion. When the heat-shrinkable film is peeled off, the film can be easily torn and peeled by being guided by the extended cut portion.

  Also, assuming that the connecting part is left between the cut and the extended cut part, the surface of the superposed part is pressed with a finger and slid from the notch to the heat shrinkable film with the width of the superposed part. When peeling off, the connecting portion is easily cut and guided to the extended cut portion, and can be easily cut and peeled off. In this case, since the connecting portion remains between the cut and the extended cut portion, the overlapping portion does not warp outward from the cut.

  Furthermore, if the reinforcing tape made of non-heat-shrinkable film material is made of cellophane or polyethylene terephthalate, these are excellent in printability, so it is easy to display the peeled part by coloring or printing a cautionary note. It can be done. In addition, since these materials have high frictional resistance, when they are attached to the surface of a heat-shrinkable film, the reinforcing tape is pressed with fingers when opened. It is possible to peel off the protective film.

  In addition, when the reinforcing tape made of a non-heat-shrinkable film material is pasted on the back surface of the heat-shrinkable film, the polymerized part is not exposed, so the strength of the film is not exposed. It can be small. Also. The surface of the heat-shrinkable film with a reinforcing tape made of a non-heat-shrinkable film material applied to the front surface is used as a polymerized part. It is possible to peel off the heat-shrinkable film by adhering to the reinforcing tape without slipping. In addition, when a superposition part made of non-heat-shrinkable film material is applied to both the front and back surfaces of a heat-shrinkable film to form a polymerized part, the strength of the polymerized part increases and the superposed part and its boundary are easy It is torn.

Next, preferred embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a packaged object which is instant cup noodles stored in a cup-shaped package. Reference numeral 2 denotes a heat-shrinkable film for wrapping the article 1 to be packaged, and a polymerized portion 4 is formed by attaching reinforcing tapes 3 and 3 made of a non-heat-shrinkable film material on both sides of the heat-shrinkable film 2. The overlapping portion 4 is provided with a cut 5 that is traversed in the width direction. The heat-shrinkable film described above is typically a polyethylene film, a polyester film, or the like, but may be commonly called a stretch shrink film obtained by mixing polypropylene with polyethylene.

  The notch 5 shown in FIG. 1 has a gate shape with the connecting parts 5a remaining between the notches 5 and the extended notches 51 and 51 provided along both sides of the overlapping portion 4. Is the most preferred. However, even if the notch 5 has the gate shape shown in FIG. 5 without leaving the connecting part 5a, the notch 5 is crossed only to reach both ends in the width direction of the overlapping part 4 without the extended notches 51, 51 shown in FIG. 5 may be included.

  Further, the reinforcing tape 3 made of the non-heat-shrinkable film material may be made of any material as long as it is non-heat-shrinkable, but is preferably made of cellophane or polyethylene terephthalate. 1 is instant cup noodles housed in a cup-shaped package, but not limited to this, instant miso soup, cup side dishes, and lunch boxes with tray 6 shown in FIG. As long as it can be packaged by a heat-shrinkable film, it can be anything including a hard cased CD, DVD and the like.

  What was comprised in this way forms the superposition | polymerization part 4 by affixing the reinforcing tapes 3 and 3 which consist of a non-heat-shrinkable film material on both surfaces of the part of the heat-shrinkable film 2 which wraps the to-be packaged object 1 Then, the notch 5 that crosses the overlapping portion 4 is provided, and the overlapping portion 4 provided with the notch 5 is to be packaged 1 such that the reinforcing tapes 3 and 3 are the heat-shrinkable film 2. Even if it is thermally shrunk after storage, the notch 5 does not shrink, so that there is no possibility that other objects will be caught in the notch 5 and torn from the notch 5 to break the packaging and reduce the product value. .

  Then, in order to open such a package, if the surface of the overlapping portion 4 is rubbed while pressing with a finger, a frictional force acts between the finger and the overlapping portion 4 and the overlapping portion 4 starts from the notch 5. The heat-shrinkable film 2 is peeled off at the width of the overlapped portion 4 by cutting the strong overlapped portion 4 and the boundary thereof. The removable film 2 can be easily removed and opened.

  In addition, as shown in FIG. 1, if it makes a gate shape leaving the connection part 5a between the extended notch parts 51 and 51 provided along the both sides of the superposition | polymerization part 4 at both ends of the notch 5, it will be superposition | polymerization part. If the reinforcing tape 3 located on the surface side of 4 is pressed and rubbed with a finger, the connecting portion 5a of the cut 5 is torn and the extended cut portions 51, 51 are linked together to form a pinch allowance, It can be easily opened by picking up the picking margin with fingers and tearing it. In this case, since the connecting portion 5a is left between the notches 5 and the extended notches 51 and 51 provided along both sides of the overlapping portion 4, the overlapping portion 4 protrudes outwardly. There is no possibility that other objects are caught in the notch 5 and tear from the notch 5 to break the package and reduce the product value.

  Further, if the package 1 is a lunch box containing the tray 6 and is heated by a microwave oven, the heat-shrinkable film 2 is further contracted, and the connecting portion 5a of the notch 5 is torn and extended by this contraction. The notch portions 51 and 51 are linked to form a pinch allowance, and there is no need to press and rub the reinforcing tape 3 located on the surface side of the overlapping portion 4 with a finger.

  Further, even if the notch 5 has a series of U-shaped gates shown in FIG. 5 without leaving the connecting portion 5a, the reinforcing tape 3 located on the surface side of the overlapping portion 4 is pressed with a finger. When the heat-shrinkable film 2 is peeled off with the width of the overlapping portion 3 by sliding the notch 5 as a starting point, the heat-shrinkable film 2 can be easily torn and peeled by being guided by the extended notches 51 and 51. Even in this case, since both surfaces of the heat-shrinkable film 2 are stuck with the reinforcing tapes 3 and 3, the superposed portion 4 does not warp outward from the gate-shaped cut 5.

  Moreover, the notch 5 may not be provided with the extended notches 51 and 51, but may be a notch that only crosses the overlapping portion. In this case, the overlapping portion 4 does not warp outward from the notch 5.

  Furthermore, if the reinforcing tape 3 made of a non-heat-shrinkable film material is made of cellophane or polyethylene terephthalate, these are excellent in printability, so that they can be easily colored or printed with a cautionary note. It can be displayed. In addition, since these have strong frictional resistance, when they are attached to the surface of the heat-shrinkable film 2, the reinforcing tape 3 is rubbed with a finger at the time of opening, so that the finger is in close contact with the reinforcing tape 3 without slipping. The heat-shrinkable film 2 can be peeled off. When the reinforcing tape 3 is made of cellophane or polyethylene terephthalate, these have high frictional resistance, so that when the reinforcing tape 3 is pulled while being pressed with the finger, the finger is caught on the reinforcing tape 3 without slipping and heat shrinkable. The film 2 can be peeled off.

  In the embodiment, the strength of the superposed portion 4 is further increased by attaching reinforcing tapes 3 and 3 made of a non-heat-shrinkable film material to both the front and back surfaces of the heat-shrinkable film 2 to form the superposed portion 4. Thus, the superposition portion 4 and the boundary thereof are easily cut off.

  However, the present invention is not limited to this, and the reinforcing tape 3 made of a non-heat-shrinkable film material is pasted on the back surface of the heat-shrinkable film 2 to form the superposed portion 4 without exposing the reinforcing tape 3. The attachment strength may be small. In addition, a reinforcing tape 3 made of a non-heat-shrinkable film material is attached to the front and back surfaces of the heat-shrinkable film 2 to form a polymerized portion 4, and the reinforcing tape 3 is directly rubbed with a finger at the time of opening. The film may be peeled off.
