Fiber-based composite material for padded mailers and corresponding systems and methods are provided herein. A fiber-based composite includes a fiber-based backing material and a fiber-based padding attached to the backing material to provide cushioning for items within a mailer. The fiber-based padding is applied as a plurality of tubular structures, each defining a perimeter extending from a first point of attachment to a second point of attachment. The perimeter further defines an apex point which is spaced apart both laterally and vertically from a center point on the backing material that is between the first and second points of attachment. A plane connecting the center point and the apex point defines an angle with the backing material that is greater than 5 degrees and less than 75 degrees.

The invention relates to the packaging of one or more articles in a packaging sheet material which is moveable from a first condition to a second, expanded, condition to improve the packaging effect of the sheet material. In accordance with the invention the sheet material includes a first portion with apertures which can be moved to an open position to create the second, expanded, condition and at least one, but typically a plurality of spaced apart, second portions which have no apertures, or a different shape and/or pattern of apertures than the apertures of the first portion, so as to form a surface of the said second portion more suitable for the application of a label and/or indications thereon when the sheet material is in the second expanded condition.

The packaging material includes a packaging material body formed into a sheet shape as a whole by welding two film sheets having an upper sheet and a lower sheet together at appropriate points; an air introduction path having the packaging material body, one side thereof serving as an air introduction port and the other side sealed; a plurality of air bags having the packaging material body while being in communication with the air introduction path, and extending in a direction orthogonal to the air introduction path; and check valves provided to respective air inlets of the plurality of air bags and preventing escaping of air having been introduced through the air introduction port and introduced into the air bags through the air inlets. The packaging material body is bent and welded at appropriate points, whereby a packaging bag for storing a packaged object is provided.

According to an aspect of the invention, provided is a bag-shaped container including a tubular film and at least one pair of engagement portions. The tubular film has an inner surface and an outer surface, and is folded in a manner that the outer surface configures both an inner surface of a bag body and an outer surface of the bag body. The at least one pair of engagement portions projects from the inner surface of the bag body, and engages with each other.

A container protective sleeve is provided. The container protective sleeve is configured to be sleeved around a container bottom portion of a container. The container protective sleeve includes a protective sleeve body. The protective sleeve body is made of rubber or a silicone elastic material. The protective sleeve body includes a bottom board portion and a side wall portion surrounding an outer periphery of the bottom board portion. The side wall portion has at least one concave portion at one side of the side wall portion corresponding to the bottom board portion and at least one extension fin relatively protruding from the at least one concave portion. The at least one extension fin extends away from the bottom board portion.

A packaging material includes a web of pouches and an outer skin. One panel of the web has an inflation pattern that is not inflated. The web has a continuous inflation channel that is in fluid communication with the inflation pattern. Each of the pouches of the web can be inflated by inflating the inflation pattern while the outer skin already attached to the outside of the web. The outer skin is attached to the web only along edge lines of the pouches. The outer skin is detached from the web between the edge lines of the pouches. The outer skin is attached to the outside of the web such that the continuous inflation pattern extends above the outer skin.
