A splicing device is provided, including: a punch plate and a counter plate arranged oppositely to the punch plate, the punch plate and the counter plate being relatively movable versus each other and configured to splice two sheets of material arrangeable in between the punch plate and the counter plate, the punch plate including an array of splicing protrusions and the counter plate including an array of splicing holes, the array of splicing holes including a number of splicing holes and the array of splicing protrusions including a number of splicing protrusions, a number of splicing holes being at least the same as a number of splicing protrusions, and a position of the splicing protrusions in the array of splicing protrusions corresponding to a position of the splicing holes in the array of splicing holes.

An apparatus and method for forming zig-zag folded logs of web material is provided. The apparatus and method allows for forming logs having different sheet lengths on a same machine. Logs of web material having weakened regions at different locations between folds in the zig-zag folded web are also provided.

Perforated stretch film tube for forming a perforated stretch film hood. A length of flattened stretch film with a thickness of between 0.0025 and 0.0055 or larger is perforated after extrution and wound around a core to form a roll of perforated stretch film tube with a plurality of perforations spaced spaced by at least an inch and having a diameter of less than inch. The roll is loaded into a palletized load hooder machine, opened with gripping arms, sealed and cut at one end to form a pallet hood, and drawn down over the palletized load and released to secure the load to the pallet.
