The present disclosure is directed to a paper towel product that will capably separate from the paper towel roll as a full sheet, a half sheet or a quarter sheet. A method of making a paper towel with machine direction perforations is also disclosed.

A glass ribbon coated with a flexible material, the flexible coating forming a flexible web portion that extends from an edge of the glass ribbon at least one millimeter. The flexible web portion can be used to facilitate handling of the glass ribbon in a manufacturing process, and may include registration markings, or perforations, that further facilitate precise positioning of the ribbon.

Systems and methods for batch processing glass substrate webs are disclosed. In one embodiment, a method of processing a glass substrate web includes applying a spacer layer to at least one of a first surface or a second surface of the glass substrate web, and rolling the spacer layer and the glass substrate web to form a spool. The spacer layer is configured such that a gap exists between the first surface and the second surface of the glass substrate web within the spool. The method further includes applying a fluid to the spool such that the fluid surrounds the spool and is disposed within the gap between the first surface and the second surface within the spool.

Methods for forming a stock roll including a folded film within another folded film include combining the films and winding them into the stock roll. In particular, one or more implementations of a method of forming a stock roll involve combining films on an extrusion tower. Thus, implementations of the present invention can greatly reduce costs and space requirements, while allowing a single stock roll to feed a bag-making machine in order to produce bag-in-bag structures. One or more implementations further include stock rolls including a first folded film within another folded film.
