Description

  More specifically, a packaging material in which a block-shaped candy or the like is packaged, and a plurality of packaging materials are collected and packaged. Specifically, a granular material packaging using a plastic film and capable of sequentially taking out contents while maintaining dead hold property. It is about the body.

  2. Description of the Related Art Conventionally, as a package for displaying and selling plate-shaped chewing gum, block-shaped candy, and the like, a package in which a plurality of pieces are collected and individual contents are aligned and fixed with an exterior material has been used. As shown in FIG. 6, the packaging form is printed on a transparent moisture-proof cellophane having a heat seal layer, the printed surface and aluminum foil are laminated by dry lamination, a paper layer is laminated, and a hot melt material ( Or a sheet material made of a laminate provided with a heat-sensitive adhesive) as a heat-adhesive layer, and heat-bonding the overlapping portions of the sheet material that is wound by winding a plurality of stacked and aligned contents in the longitudinal direction. The body portion 102 is formed, and both end portions 103 of the body portion 102 are sealed by folding and thermal bonding of a sheet material, so that a rectangular columnar package 101 is formed. In general, the rectangular columnar package 101 has a tear tape 111 (cut tape) that circulates around the body portion 102 from one side edge thereof attached to the innermost surface of the sheet material, and is opened with the end portion of the tear tape. The barrel 102 is torn starting from notches (or cuts) 112 formed on both sides of the end portion to which the tear tape is attached, and the vicinity of one end portion is opened, and after opening, As the consumer consumes the contents, the consumer freely peels off the package body and takes out the accumulated contents, or folds up the remaining body and recloses it. The part that was folded in did not look good.

  The moisture-proof cellophane that has been used in the above laminate is easy tearing that can be easily torn from the end portion, and the outer shape retention property that maintains the folded position and shape, so-called dead hold property (hereinafter, folded) Maintaining the position and shape is described as dead hold.), But consumes a large amount of water in the production process, and the sulfur compound produced as a secondary treatment is made pollution-free and processed. For this reason, production is on a downward trend because the burden on the environment is excessive due to high costs.

  As an alternative to moisture-proof cellophane, a laminated body of plastic film and paper has rigidity due to the laminated paper, but has a high repulsive force when folded in reverse, so when a package is formed The shape of the rectangular pillar is not maintained, and the film peels off during heat sealing, and the tear strength and piercing strength of the film is strong, so the tearability from one end of the body is inferior. Cut tape), it was torn in the stretching direction but was inferior in tearability at an arbitrary position.

  Focusing on the above problems, the inventors, in Japanese Patent Application Laid-Open No. 2008-74447 of Patent Document 1, use a laminated body using a plastic film with a low environmental load in place of the moisture-proof cellophane, and have a dead hold property. The packaging material which is excellent in tearing property which has tearability is proposed (for example, patent document 1). In addition, Japanese Utility Model Laid-Open No. 59-133465 of Patent Document 2 proposes a packaging material in which tubes attached to a container are sequentially cut out by an attached cut line and can be used as wrapping paper ( For example, Patent Document 2).
