本発明はストロ−等の棒状物を包装する棒状包装体に関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rod-shaped package for packaging rod-shaped objects such as straws.

フィルムの非融着部分に熱収縮によるしわ４が発生し、
包装体の外観を著しくそこなうのが一般的である。As shown in FIGS. 1 and 2, the conventional rod-shaped packaging body is one in which a straw 3 is covered with synthetic resin band-shaped packaging films 1 and 2, and both films 1 and 2 are fused at the periphery. It is known that the front film 1 is convex and the back film 2 is flat. These conventional rod-shaped packaging bodies use packaging films that have the same heat shrinkage rate and rigidity on the front and back sides, and when these films are packaged by heat sealing, both films or the unfused portion of the front film may wrinkle due to heat shrinkage. 4 occurs,
Generally, the appearance of the package is significantly impaired.
本発明が解決しようとする問題点は従来のものの欠点で
ある融着時におけるしわの発生を防止することてしわが
生じない棒状物包装体を提供することにある。The problem to be solved by the present invention is to provide a rod-like article package that does not cause wrinkles by preventing wrinkles from occurring during fusion bonding, which is a drawback of conventional products.
本発明は、上記問題点を解決するためになされたもので
、棒状物を包み包装体を構成するフィルムのうち凸状と

を用いたものである。The present invention has been made to solve the above problems, and the convex front film of the film constituting the package that wraps the rod-shaped object has a lower heat shrinkage rate than the flat back film. It uses a thermoplastic resin film with limited stamina.
これらの欠陥を改善するために本発明者が検討を加えた
結果、次のような結論を得た。即ち、ストロ−等の棒状

のしわを防止することが可能である。As a result of the inventor's studies to improve these deficiencies, the following conclusions were reached. In other words, when packaging a stick-like object such as a straw, the front film has a higher heat shrinkage rate (glycerin bath 120°C, 130C13O) than the back film (05 to 5 %
It is large, with a stiffness of -3 to 2% in the width direction, and a stiffness (measured by ASTM D747) of 2% in the length direction of the package.
00~800 Kg/cJ, 100~600 in width direction
The above-mentioned wrinkles can be prevented by using a film with a small Kg/cnl.

透明性やステイフネスも優れている。An example of a preferable material is one in which a 20μ thick unstretched polypropylene film made by a casting method is used as the front film, and a 30μ thick polypropylene film biaxially stretched by a tenter method is used as the back film.
It also has excellent transparency and stiffness.

Of course, it can be used. Furthermore, by orienting low-density polyethylene films that are exactly the same on the front and back sides, it becomes possible to use the film by appropriately changing its heat shrinkage rate and stiffness.
尚、裏フィルムは必らすしも平担なものでなくともよく
、幾分凸状をなしたものでも同様の効果が得られる。Note that the back film does not necessarily have to be flat, and the same effect can be obtained even if it is somewhat convex.
