Web-wound rolls with a web edge treatment by printable adhesive compositions and processes to make the same are provided. The web-wound rolls include a substrate web having at least two web edges. One or more quantities of adhesive are disposed and subsequent curing adjacent to one or both of the web edges. The substrate web is wound upon itself in multiple revolutions about a central core, and each revolution is held substantially separate from the next by the adhesive.

A plastic film roll includes: a convolute cardboard tube including a tubular body having a tubular body wall formed by a plurality of layers of a straight rolled cardboard sheet having a weight equal to or less than 300 gsm; a plastic film wound about the convolute cardboard tube to form a plurality of plastic film windings around the convolute cardboard tube, the plastic film windings creating a radial compression force equal to or greater than 10 bar on the tubular body wall, wherein the cardboard sheet includes a plurality of fibers, at least a majority of the fibers being substantially aligned in a tangential direction relative to the tubular body to allow the convolute cardboard tube to resist the radial compression force.

A roll includes a core having a tubular shape and a laminate wound around the core. The laminate includes a process film, a surface coat layer formed from a fluorine resin, a substrate layer, an adhesive layer, and a release liner formed from polyethylene terephthalate (PET) in this order in a laminating direction. The process film is formed from at least of polyethylene terephthalate (PET), polyolefin, and polyvinyl chloride (PVC), and is thinner than the release liner.

Medicine packaging apparatuses and methods for accurately determining a remaining sheet amount of a medicine packaging sheet are described. The apparatus includes: a roll support section to which a core tube of a medicine packaging sheet roll is attached; a sensor disposed in the roll support section for outputting a count value according to a rotation amount; a wireless reader-writer unit for writing information to a core tube IC tag and reading said information; an information generation section for generating information to be written to the core tube IC tag; a remaining sheet amount estimation section for estimating a current amount of remaining sheet based on the information and dimensional information of the core tube; and a controller which selectively performs an operation if a reference time-point count value is not yet written to the core tube IC tag and another operation if the count value is already written thereto.

Provided is a sticking body holding member capable of suppressing generation of slack in a carrier tape without excessively strong winding of the carrier tape. A sticking body holding member includes a plurality of sticking bodies, a carrier tape, and a reel. The sticking bodies are each configured to have a planar shape, and each include a first surface being an adhesive surface that is stickable with respect to an adherend. In the carrier tape, the plurality of sticking bodies are stuck and arranged in a line. The carrier tape is wound around the reel. A second surface of the sticking body is provided with an adhesive region having adhesiveness and an adhesion suppressing region where adhesiveness is suppressed, and the second surface of the sticking body is configured to have weaker adhesiveness than adhesiveness of the first surface.

A wrapping material roll includes a flexible sheet having a length and a width. The sheet is rolled concentrically about an axis parallel to the direction of the width such that a longitudinal end of the sheet is located along a circumferential side of the wrapping material roll. At least a part of the longitudinal end is folded along a folding line over at least part of the width.
