Technical Field

The present invention is in the field of packaging systems and materials. More specifically, the present invention is in the field of protective packaging.

Background

In the case of paper-based protective packaging, the sheet of paper is crumpled to produce a dunnage. Most commonly, this type of dunnage is produced by: a substantially continuous strip of paper is extended into a dunnage conversion machine that converts a compact supply of stock material (e.g., a roll or stack of folded paper) into a low density dunnage material. A supply of stock material (e.g., in the case of folded paper) is pulled into the converting machine from a stack that is continuously formed or formed with discrete lengths connected together. The continuous strip of corrugated sheet material may be cut to a desired length to effectively fill void spaces within the container holding the product. The dunnage material can be produced on the basis of the needs of the packaging machine.

The dunnage supply material may be linkable. For example, the dunnage supply arrangement includes a first supply unit of an elongated web of material in a high density arrangement, where the material may be converted into a low density dunnage, and the connecting members may include a bonding surface that is sufficiently adhesively bonded to a longitudinal second end of the second supply unit of material for drawing the material of the second supply unit into a dunnage mechanism (e.g., a public class that daisy-chains two supply units together), as described in greater detail in U.S. patent application publication No.2014/0038805, the entire contents of which are incorporated herein by reference.
