The present disclosure provides a sheet storage apparatus and a sheet processing apparatus capable of effectively reducing tension applied to the entrance portion of a storage bag that stores sheets at the time of sealing the storage bag. The sheet storage apparatus according to the present disclosure includes a sealing unit that seals a predetermined portion of the storage bag storing sheets and a tension reducing unit that reduces the tension applied to the predetermined portion.

An apparatus for sealing a bag opening includes a retaining member and a slide member adapted to slide into said retaining member. The retaining member includes an elongated opening that extends through at least one open end of the retaining member. A bottom stop is provided at an end of the retaining member that is opposite to the open end of the retaining member. Alternatively, the retaining member includes an elongated opening that extends through both ends of the retaining member and the bottom stop is omitted. The slide member includes at least one protruding portion that protrudes from the retaining member when the slide member is slid into and retained by the retaining member. The slide member abuts the bottom stop of the retaining member when such bottom stop is provided within the retaining member. In cases in which the retaining member is provided with two open ends, the slide member may include two protruding portions that protrude from both open ends of the retaining member.

A collection assembly (10, 10a) for flowable materials includes a central, flexible bag (12, 12a) with a collection skirt (14, 14a) secured to the bag (12, 12a) and extending outwardly from the open top (20, 20a) of the bag (12, 12a). In use, the assembly (10, 10a) is placed at a collection site with the bag (12, 12a) in a collapsed condition and the skirt (14, 14a) is deployed about the bag (12, 12a). Material (36) is then placed on the assembly (10, 10a) over the open top (20, 20a) and, as necessary, the skirt (14, 14a). The skirt is then elevated using marginal gathering apparatus (16, 16a), thereby causing the material (36) to flow into the bag (12, 12a). The skirt (14, 14a) may then be gathered and closed, forming a duffel closure for the assembly (10, 10a).

A polyethylene-based thermally-shrinkable film for pack-in box packaging, in which: a product is not damaged due to breakage or looseness of a film during packaging and transportation of the product; because of the low-temperature shrink characteristic, the product is not exposed to excessively high heat during shrink wrapping and power consumption in a shrink tunnel can be reduced; and because of a small thickness of the film, garbage and other wastes can be reduced. The film is a polyethylene-based thermally-shrinkable multilayer film for pack-in box packaging obtained by biaxial orientation in MD and TD and stretching in MD only further after biaxial orientation. Preferably, the film is a polyethylene-based thermally-shrinkable multilayer film for pack-in box packaging in which the film as a whole has a thickness of 25 μm or less.

Method for filling and closing a package including the operations of introducing two arms through the mouth, each one having or bearing a gripping tool and impressing a mutual distancing movement on the arms to expand the package with a retention mechanism which operates outside the package to grasp the walls of the package arranged between the arms and the retention mechanism while the retention mechanism approaches and fits over the gripping tool of each arm, such that when the arms move in the direction of the mouth of the package, the arms carry the grasped walls of the package to produce folds towards the interior of the package. For flexible tubular net packages, the at least one gripping tool on each arm has the shape of a protuberance and that the method includes passing through a wall of the package with the gripping tool

A bag film crimping device has a socket having top and bottom components joined by a bridge. Each socket component has a pair of opposed limbs, and each limb having inwardly directed teeth. A plug fits between the limbs with a friction fit in a movement from proximal to distal, and it has outwardly directed teeth for engagement with the teeth of the socket. A cover slide over the socket to cover a space at a distal end between the limbs when the socket and plug components have been separated after crimping. The cover includes has tines for prising a socket limb from the plug as the cover is pressed distally after it has previously been used to cover exposed edges of film after crimping and the top and bottom components have been separated.

Provided is a film-packaged tissue assembly package in which an outlet forming portion is not unintentionally broken. The problem is solved by a film-packaged tissue assembly package in which a plurality of substantially hexahedron-shaped film-packaged tissues having an upper surface having an outlet forming portion are arranged and packaged in a gusset packaging bag having a grip portion on the top surface side, wherein a plurality of film-packaged tissues are arranged in a substantially rectangular parallelepiped shape in such a manner that the end surfaces face the top surface side where the grip portion is provided, and a bottom surface side facing the top surface side, and the film-packaged tissue is packaged in such a manner that the outlet forming portion has a shape in which an easily tearable line having cut portions and non-cut portions arranged alternately protrude toward the outside, the interval between non-cut portions at one end portion is smaller than the interval between non-cut portions at the other end portion, and the side where the end portion with a smaller interval between non-cut portions is located on the top surface side.
