Abstract: The present disclosure is directed to one or more embodiments of mailer package assemblies including a fixed release liner and a mailer package. The fixed release liner is removably or detachably coupled to the mailer package by an adhesive layer. The fixed release liner includes one or more wickets (e.g., openings) such that the fixed release liner may be mounted to a wall by inserting fasteners (e.g., tack(s), pin(s), etc.) into the openings. The mailer package may be removed, detached, or decoupled from the fixed release liner by pulling on the mailer package decoupling the fixed release liner from the mailer package. After the mailer package is removed, an packaging associate may place an item or product within the mailer package to be shipped to a consumer. After the mailer package is removed from the fixed release liner, the fixed release liner remains mounted to the wall.

Abstract: The present disclosure is directed to a shipping container with a corrugated medium that lines an interior pocket of the shipping container as well devices and components (e.g., corrugating rollers, corrugating machines, scoring rollers, and scoring machines) that are utilized to manufacture the shipping containers. The corrugated medium has flutes that cushion, support, and protect a product that is shipped within the shipping container. The corrugated medium may include a first portion with first flutes and a second portion with second flutes that are offset relative to the first flutes. The offset first flutes and second flutes results in peaks of the first flutes nesting within valleys of the second flutes, and peaks of the second flutes nesting within valleys of the first flutes.
