A multilayer product made of paper-like material, includes at least one corrugated layer bonded to a first flat layer of cannet?. A least one corrugated layer is constituted by a sheet of cannet? which is shaped so as to form a wave. A method is also related for providing a multilayer product made of the paper-like material.

A packaging material including one or more expandable layers that provide protection to contents of a packaging enclosure formed with the packaging material. The packaging material includes at least a first layer and a second layer bonded to one another. The first layer is pulled or extended in a first direction that is effective to cause the second layer to expand in a second direction. The second layer is a cut-patterned layer which increases in thickness and provides structural strength to the packaging material when expanded.

An invention relates to a field of mechanical structures intended to suppress free convection in rectangular cavities and, at the same time, to diminish infrared radiation through these mechanical structures. A thermo-insulating structural unit comprises following units: a rectangular frame constructed from two opposite transverse strips and two opposite longitudinal strips; the most part of each longitudinal strip is corrugated; a set of first parallel lines, which are joined with the vertices of the corrugations of the opposite longitudinal strips; a set of second parallel lines, which are joined with the valleys of the corrugations of the opposite longitudinal strips; a flexible film, which is situated between the first and second lines in such a manner that this flexible film walks around the second parallel lines on their underside and the first parallel linesfrom above.

In one embodiment the flexible film is transparent or translucent.

The disclosed embodiments relate to an insulative protective packaging panel constructed using recyclable and biodegradable materials. The insulating panel can include an outer shell and a core material constructed of paper. The core can include a paper sheet or a plurality of paper sheets with a plurality of protrusions formed in an alternating pattern out of the plane of a surface the paper. The paper sheet or sheets are folded in an undulating staggered pattern to create an alternating staggered layer structure. The layered structure core is adhered to the outer shell. The resulting structure is an insulating packaging panel that can be easily recycled.

An insulated bag may include an integral structure. The integral structure may include a first portion comprising first and second extension portions. The integral structure may include a second portion and a third portion attached at corresponding edges and each extending approximately perpendicular from the first portion. The first, second, and third portions each may include a first layer and a paper sheet formed into a wave pattern attached to the first and second layers.
