A blank including a single rectangular sheet of paperboard having opposed top and bottom edges and opposed left and right edges. The sheet has a midline spaced equally from the left and right edges, with a cut that extends from the top edge to a point spaced from the top edge, and a fold line that extends from the point to the bottom edge. The sheet also has a first zone that extends from midline to right edge along the bottom edge, a second zone that extends from bottom edge to a line spaced from the top edge along the right edge, a third zone that extends from midline to left edge along the bottom edge, and a fourth zone that extends from bottom edge to the line along the left edge. The first and second zones are configured to join the third and fourth zones.

In the preferred embodiments, the present invention provides substantially improved slit sheet cushioning products by advantageously combining novel paper properties with novel slit patterns for improved features and characteristics. In some illustrative and non-limiting example embodiments, cushioning products of the present invention can include, e.g., a novel slit sheet material in combination with extensible paper employed as, e.g., a cushioning pad or as cushioning within an envelope product, wherein the cushioning product can be substantially more resilient, but, yet, e.g., thinner for better utilization of space.

According to some illustrative embodiments, a system and method is provided that includes, e.g., means for continuously conveying an assembly of layered sheets including a first paper sheet, at least one expanded sheet and a second paper sheet in a conveying flow between, e.g., a rotary mandrel or member at an upstream position in a direction of conveyance and a rotary die crushing and cutting tool, with said rotary mandrel or member and said rotary die crushing and cutting tool maintaining the at least one expanded sheet in an expanded state, said rotary tool having a crushing component that crushes a portion of the at least one expanded sheet such as to form a flap forming region of an envelope and a cutting component that cuts the assembly of layered sheets such as to separate individual envelope units.

Bag made of paper material for archiving articles comprising a first and a second sheet-like element and a closure flap projectingly extended from the first sheet-like element and susceptible of being folded in partial superimposition on the second sheet-like element in order to close the bag. The closure flap is provided with a first portion for a first closure of the bag and with a second portion for a second closure of the bag, and between such first and second portion a tear tape is arranged which is susceptible of being torn in order to separate the first portion from the second portion. In addition, the bag is provided with a removable flap projectingly extended from the second sheet-like element between a second free end and a weakening line, which is susceptible of being torn in order to remove the removable flap from the second sheet-like element.

A mailer (10) includes front (12) and rear (14) corrugated panels having interior and exterior surfaces and connected to one another along a fold line (16), wherein the interior surfaces of the front and rear panels have an area (52) of patterned creases formed therein to allow the corrugated panels to conform to an article placed into the mailer.

An environmentally-friendly alternative to polyethylene garment and other product packages is made of paper, which can be recycled, re-pulped or composted. Each such package includes two parallel coextensive elongated sheets of paper joined together along their respective side edges and along a top edge by heat seal or an adhesive. The two sheets of paper define an expandable volume therebetween. Central portions of the two sheets of paper are separable from each other to increase the volume to accept an article of clothing or other product. Rolls of paper-based product protection material may be manufactured, from which individual packages may be made or cut. Methods and apparatus for manufacturing the product protection material are disclosed.
