A packaging box for a roll-shaped material wound around a cylindrical core, including a prism-shaped case body, and respective side surface portions at both ends in a longitudinal direction of the prism-shaped case body, the prism-shaped case body and the side surface portions being formed of a single sheet member, that includes a holding unit inserted into the cylindrical core of the roll-shaped material to hold the roll-shaped material within the prism-shaped case body, wherein, when the holding unit is inserted into the cylindrical core of the roll-shaped material, a region facing an end portion of the cylindrical core in a cross direction intersecting the longitudinal direction in which the prism-shaped case body extends, is formed with a recessed portion that is recessed in the cross direction.

A package structure of a roll-shaped thin film includes a thin film roll and a buffer layer. The thin film roll includes a winding core and a thin film wound around the winding core, and the buffer layer is wound around an outer circumference of the thin film. An end portion of the buffer layer is covered with an inner surface of an end portion of the thin film, and the thickness of the buffer layer is in a range of 1-20 mm.

Provided are a packaging container, a packaging method, and a method for carrying metal foil, which can suppress damage and deformation of the packaging container and enable stable carrying even if the packaging container is carried while suspending it in the midair. A packaging container made of corrugated cardboard includes: a pallet 2 having leg portions 21; a body frame 3 arranged on the pallet 2, the body frame 3 having bearing grooves 31 at end wall portions 32 opposing to each other; and a lid portion 4 provided on the body frame 3, wherein each of the leg portions 21 is arranged on an inner side than each of the end wall portions 23 of the pallet 2.

A dispensing device includes a container retaining a dispensable material, which prevents the material from breaking prior to being dispensed or over-dispensing material by including a mechanism to slow the dispensation of the material, and also aids in breaking the material subsequent to the material exiting the container. The container has a faceplate with at least three members forming a substantially triangular aperture through which the dispensable material is fed. The three members include a pair of opposing flanges forming the triangular aperture therebetween. The pair of opposing flanges further form a substantially linear slot therebetween and contiguous with the triangular aperture, with the dispensable material further fed through the slot. Each of the pair of opposing flanges has a curved surface forming a side of the triangular aperture.

An extensible slit sheet paper product is produced having an expandable slit pattern that forms open cells upon expansion of the paper product. The paper product is an extensible paper having an extensibility in the range from 1-9% in the machine direction and 1-5% in the cross direction. The expansion produces an array of hexagonal cells. The expanded extensible paper can be used to wrap an object for shipping by wrapping and cushioning the object in the expanded slit sheet material. The extensible, expandable slit sheet paper can be wrapped around itself to produce a void fill product.

In the present invention, a porous separator roll (12U, 12L) is wrapped with a wrapping material (21) whose average transmittance with respect to light having a wavelength of 360 nm to 390 nm is 25% or lower. From this, it is possible to provide a package of a porous separator roll which package can inhibit change in color of a separator, and can thus provide a high-quality separator with good appearance.

The invention relates to a package for a material roll, for example, an abrasive material roll. The material roll comprises a package body part and a lid part, wherein the package further comprises positioning openings at both end sides of the package for positioning the material roll inside the package. Positioning openings are arranged to be formed when lid part of the package is closed. The invention further relates to a material roll, a material dispenser and a use of a package with a material roll.
