Description

  The present invention relates to a packing method for packing various articles, in particular, food, medicine and other industrial products, or parts of industrial products, and the like, and a packing body packed by the method.

  Needless to say, various articles have been conventionally packaged in various forms and transported or stored. For example, industrial products and parts thereof are manufactured, and when they are transported to other factories, distribution centers, stores, consumers' homes, etc., they are often packed and transported in so-called cardboard boxes. With regard to the packaging of these products, sufficient measures are required so that the packaged items are not damaged.

  In this regard, prepare a box of sufficient size even with the packaged items, and put a cushioning material such as foamed material or air cushioning material in the box, and place it around the packaged item. A packing method has been widely used in which an object to be packed is held at a central position in a box by filling the space portion. According to such a packing method, even if the box containing the packaged item is shaken or dropped, the packaged item is held at a predetermined position in the box, and the cushioning material serves as a cushion. The packed items will not be damaged.

  However, the packaging means as described above is problematic because of the large amount of packaging material used. Therefore, in recent years, a method of packaging an object to be packed with a heat-shrinkable film and fixing it in a box has been used (see Patent Documents 1 and 2 below).

JP 2001-122326 A JP 2008-030777 A

  Certainly, according to the conventional packing method using the heat-shrinkable film, the amount of packing material used is reduced, and the waste of resources can be reduced. However, in this conventional packing method, it is necessary to cover the object to be packed with a heat-shrinkable film and then apply heat to the entire object to be packed and the heat-shrinkable film to shrink the film. Therefore, it cannot be used for packaging products that are sensitive to heat, such as food, medicine, and electronic parts.

  The present invention has been made in order to overcome the above-described problems, and reduces the amount of packing material used, and suitably packs the package object without applying heat to the package object. It aims at providing the packing method which can be done.

  In order to solve the above-described problems, the packing method according to the present invention is such that a packaged material is packaged with a base material and a packaging film to form a packaged product package, and this is packed in a box. A packing method is to cover an object to be packaged placed on a base material with a packaging film, and to form a packaged object package by adhering both ends of the packaging film to the back surface of the base material. It is characterized by that.

  According to the packaging method of the present invention, the packaged material placed on the base material is covered with the packaging film, and both the ends of the packaging film are bonded to the back surface of the base material, The object can be held by being sandwiched between the base material and the packaging film, and packing can be performed simply by putting the packaged object package formed in the box into the box. It is possible to pack an object to be packed without giving a mark.

  Moreover, in the packing method according to the present invention, the both ends of the packaging film may be bonded to the back surface of the base material by pulling the both ends of the packaging film and bonding them to the back surface of the base material. In this way, the object to be packed is more reliably sandwiched between the base material and the packaging film, so that the possibility of the object to be packed being displaced from the base material during transportation is reduced.

  Furthermore, in the packaging method according to the present invention, a back surface of the base material may be provided with an adherend means in advance, and the packaging film may be adhered to the base material by the adherend means. The means may be such that the synthetic resin film is attached in advance to the back surface of the base material, and both ends of the packaging film are bonded to the back surface of the base material by heat welding to the synthetic resin film. In this way, packing can be performed with a simple configuration.

  Further, in the packing method according to the present invention, the surface of the base material can be provided with a non-slip means so that the object to be placed does not slip with respect to the base material. If it does in this way, a to-be-packaged item can be fixed to a predetermined position more certainly.

  Furthermore, in the packaging method according to the present invention, the base material is formed of a flat plate-like member, and has a substantially rectangular base body in plan view on which the article to be packed is placed, and a plurality of base materials formed integrally with the base body. When the base material is put into the box by bending the bent piece, the bent piece comes into contact with the inner bottom surface, the side wall surface, and the back surface of the lid portion, Thus, if the packaged article package is put in a box and packed, the packaged article may be prevented from moving in the box. In this way, the packaged material does not move within the box simply by bending the folded piece and placing the base material in the box and packing it. Can be protected.

  As described above, according to the packing method of the present invention, the packaged material placed on the base material is covered with the packaging film, and both end portions of the packaging film are simply bonded to the back surface of the base material. Thus, the packaged item can be held between the base material and the packaging film, and packing can be performed simply by placing the packaged product package in the box. Even if a large amount of cushioning material is not used and heat is not applied to the entire package, the package can be fixed at a predetermined position in the box with a simple structure and the package can be securely protected. Can do.
