Provided is a polyester film roll which has less wrinkles and film surface defects, exhibits no deviation of winding, and is suitable for secondary processing such as coating and vapor deposition. The polyester film roll is obtained by winding a biaxially oriented polyester film around a core, and is characterized by satisfying requirements (1)-(3) below: (1) the average winding hardness of the surface of the polyester film roll is in the range of 500-700; (2) the variation rate of the winding hardness of the surface of the polyester film roll in the film width direction is 1-5%; and (3) the variation rate of the average winding hardness from the surface of the polyester film roll to the core is 3-10%.

This disclosure relates to a tissue paper product including between two and four plies, including at least a first ply and a second ply, the two plies, three plies, or four plies being ply-bonded to form the tissue paper product, the first ply and the second ply being the outermost plies of the tissue paper product, a grammage of the tissue paper product being to 50 g/m2 if a total number of plies of the tissue paper product is 2, 34 to 65 g/m2 if a total number of plies of the tissue paper product is 3, and 55 to 95 g/m2 if a total number of plies of the tissue paper product is 4, the first ply being made of Conventional Wet Press (CWP) paper that has been embossed with a heated embossing roll, the second ply being a structured paper ply.

A glass roll is provided. The glass roll includes a winding core having a central axis, a self adhesive film wound on the winding core about the central axis, and a glass ribbon wound on the self adhesive film about the central axis and attached onto the self adhesive film. In a cross-section of the glass roll that is parallel to the central axis and along an entire length of the glass roll, cross-sections of the self adhesive film may alternate with cross-sections of the glass ribbon.

The disclosure relates to a method for producing a circumferential packaging for a paper roll. The paper roll has a wound paper web and two opposing end faces and a circumferential surface that connected the end faces to each other. The method includes the following steps: applying a protective material in liquid form to an end section of the paper web by at least one application unit, the protective material being applied to one of two sides of the end section of the paper web, winding up the end section of the paper web, so that the end section forms at least one outer layer of the paper roll, and curing the protective material, resulting in a protective layer that covers the circumferential surface.

A method (400) for producing packages (112) holding liquid food products from a web (102) of packaging material, wherein the web (102) comprises a number of blanks (300) placed after one another, wherein each blank corresponds to one package, the method comprising receiving (402) a reel (204) holding the web (102) of packaging material, capturing (402) reel data (210) from a tag (206) attached to the reel (204), transferring (404) the reel data (210) to a printing information database (218), receiving (406) printing information data (PID) (220) related to the reel data (210) from the printing information database (218), printing (408) décors on each of the blanks (300) of the web (102) of packaging material based on information provided via the PID (220) such that a décor provided web (246) is formed, transferring (410) the reel data (210) to a packaging machine information database (224), receiving (412) packaging machine information data (PMID) (226) related to the reel data (210) from the packaging machine information database (224), and forming (414) the packages (112) from the decor provided web (246) in a packaging machine (100) based on information provided via the PMID (226).

The purpose of the present invention is to provide a storage state in which a reactive compound layer can be stably maintained in a polymer film having a reactive compound layer on the surface. The film roll is obtained by winding together: a first polymer film having a reactive compound layer on the surface, and a second polymer film having a surface roughness (Ra) of 0.1 μm or more and a modulus of elasticity of 300 MPa or more and 10 GPa or less. The film bundle is obtained by laminating the first and second polymer films. Preferably, storing the film roll and the film bundle at a low temperature enables a thin layer of a reactive compound to be stably maintained.
