A supply of cushioning material for wrapping at least one object comprises a stack formed of a multitude of prefabricated sheets of three-dimensional cushioning material. The invention proposes that adjacent sheets are connected to each other by means of a releasable adhesive system, the adhesive system being designed such that the connection can be released without auxiliary means, i.e. without special heat exposure and without chemicals and without special tools simply by mechanical action, and non-destructively, i.e. without damaging the cushioning material.

An inflatable packaging web (3201) includes a continuous web of preformed pouches (3200) and an outer skin (612). The continuous web of preformed pouches is defined by two panels (18) connected together along first and second side edges (14) and either connected together or folded along a bottom edge (20). At least one of the panels is inflatable. The outer skin is disposed over at least one of the inflatable panels. The outer skin is attached to the at least one of the inflatable panels along at least a portion of the height of the first and second side edges. The preformed pouch includes at least one fold such that a folded portion (3215) of the two panels is folded over a first portion of the two panels.

Packaging material is provided. The packaging material can include at least one web layer having a surface that includes first and second regions. When corresponding first regions are overlaid with each other and corresponding second regions are overlaid with each other, the overlaid first and second regions can cooperatively surround a cavity. The packaging material further can include a first sealing material disposed in the first region and configured to seal together the corresponding first regions upon application of first conditions to the first sealing material, and a second sealing material disposed in the second region and configured to seal together the corresponding second regions upon application of second conditions to the second sealing material. The second sealing material can be configured such that the first conditions applied to the second sealing material are insufficient to cause the second sealing material to seal.

A shipping mailer has a first wall and a second wall that at least partially define an interior of the shipping mailer. The shipping mailer has a closed first end portion and a second end portion, the second end portion comprising an opening sealable by a closure. A plurality of corrugations are coupled to the first wall and to the second wall in the interior of the shipping mailer. The corrugations of the first wall and the corrugations of the second wall have respective preformed fold lines at the closed first end portion about which the first wall and the second wall are configured to fold when an object is inserted into the shipping mailer to create an end wall extending between the first and second walls at the closed first end portion of the shipping mailer.

A shipping package and method of making a shipping package having a flexible inner sheet having a first surface and a second surface. The method includes providing one or more sheets of flexible material, joining the sheet(s) to form an article reservoir for accepting an article to be shipped, one or more expansion chambers, and an article retrieval feature. The expansion chambers can be inflated or otherwise expanded to provide structure to the package and to protect the article in the article reservoir.
