A container comprised a container body having a first cavity for receiving a product therein, the container body having a front surface, back surface, first sidewall and second sidewall, and a cover having an opening extending thereinto, said opening configured to receive said container body therein, the cover comprising an outer wall, an inner wall and a second cavity defined between said outer wall and inner wall, said second cavity housing a protective material therein. The protective material moves the cover from a first configuration defining a first inner profile of the inner wall of the cover to a second configuration defining a second inner profile of the cover, said second inner profile being smaller than the first inner profile.

A shock absorbing mat/tile comprises a body having a generally planar, major top surface and an opposite bottom surface and a plurality of shock absorbing members depending from the bottom surface. At least one of the shock absorbing members has at least one relief formation formed therein configured to accommodate lateral expansion of the shock absorbing member during axial compression thereof.

An air cushioning material includes: a belt-like part between a first and second air cells into which air is sealed, wherein side edges of the first and second air cells are connected to each other via the belt-like part; and an air flow passage that is formed in the belt-like part and communicates the first and second air cells, wherein at least a part including the air flow passage in the belt-like part is in a shape folded in a way from the first air cell to the second air cell.

A shock and vibration isolation assembly for absorbing the energies generated from movement of a product carried thereon includes a pallet or a lower panel having an upper surface, an upper panel above the upper surface, the upper panel configured to support the product or a pallet thereon. The assembly further includes a plurality of flexible visco-elastic rings affixed to at least one of said upper surface of said pallet or lower panel and a facing surface of the upper panel. A frame member disposed between and affixed to the upper surface of the pallet or lower panel and the upper panel to seal the space therebetween. The frame member encircles the plurality of flexible rings and is formed of a resilient substantially liquid-impermeable material.

A substrate having inner and outer major surfaces, a plurality of edge surfaces, and a plurality of corner surfaces; and at least one of: (i) a coating applied over a limited area of the outer major surface of the substrate to produce a composite structure, (ii) an intermediate layer applied to the inner major surface of the substrate, and (iii) an elongate discontinuity disposed at one or more corners of the substrate, each of which operates to reduce catastrophic failures in the substrate resulting from a dynamic sharp impact to the outer major surface of the substrate.

A multi-layer foam sheet with an apparent density of 30 to 300 kg/m.sup.3 and a thickness of 0.05 to 2 mm, including a foam layer containing a polyethylene-based resin, and an antistatic layer fusion-laminated by coextrusion on each of both sides of the foam layer. The antistatic layer has a basis weight of 1 to 10 g/m.sup.2 and contains a polyethylene-based resin, a polystyrene-based resin, a styrenic elastomer, and a polymeric antistatic agent, with the polystyrene-based resin being contained in the antistatic layer in an amount of 15 to 70% by weight.

The protective packaging product includes superimposed upper and lower honeycomb layers 1 and 2 extending between a pair of flexible side members 3 and 4. Each honeycomb layer is formed of flexible paper strips arranged face-to-face and bonded to each other at a series of spaced attachment locations. The honeycomb layers are expandable to form an array of hexagonal cells which are open at both ends. An item such as a surfboard can be inserted between the layers 1 and 2 so that the layers and the flexible side members conform to the shape of the surfboard and protect it against impact damage.

According to some illustrative embodiments, a protective product is provided that includes: an envelope having a two-layer wall structure, the two-layer wall structure including a) a first outer paper layer, and b) a second inner paper layer, wherein the second inner paper layer includes width-wise positional variations of the side surface of the second inner sheet that cushions items placed within an inner pouch of the envelope, and forms an interior wall of the inner pouch of the envelope and directly contacts the items placed within the inner pouch of the envelope. In some preferred implementations, the width-wise positional variations of the side surface of the second inner paper layer includes pleats, undulations and/or embossments, and, preferably, the pleats, undulations and/or embossments include ridges that extend perpendicular or substantially perpendicular to an outlet of the envelope.

A composite material and structure. The structure has a folded sheet having a rigid inner layer sandwiched between flexible outer layers. The sheet has an undulated shape with alternating summit and valley portions. Intermediate portions each extend between adjacent summit and valley portions. At least one score line extends through at least one of the flexible outer layers. The sheet is folded about the at least one score line. A method of forming a structure from a sheet having an undulated shape.

Provided is a cushioning material obtained by stacking a plurality of cushioning sheets, in which the plurality of cushioning sheets include a first cushioning sheet, a second cushioning sheet having a strength stronger than that of the first cushioning sheet, and a third cushioning sheet having a strength stronger than that of the second cushioning sheet.
