Provided is a method for producing a polyethylene-based resin extruded foam sheet by extruding and foaming a foamable molten resin composition formed by kneading a mixture containing a low-density polyethylene, a physical blowing agent, and an antistatic agent, wherein the foam sheet has a thickness in a range of from 0.05 to 0.5 mm, and the antistatic agent is a polymeric antistatic agent having a melting point whose different from the melting point of the low-density polyethylene is in a range of from 10 to +10 C., and having a melt flow rate of 10 g/10 min or more. This method enables a novel polyethylene-based resin extruded foam sheet to be obtained that is of high quality such that formation of a small hole or a through-hole has been reduced or eliminated, and has both excellent strength and a shock-absorbing property despite a very small thickness even in medium- or long-term continuous production, and besides, exhibits a sufficient antistatic property, thus suitable as a glass plate interleaf sheet.

A progressive stage load distributing and absorbing system that lies below a superstructure material which is exposed to percussive forces. The progressive stage load distributing and absorbing system is interposed between the superstructure material and a foundation. The system has a barrier layer that lies below the superstructure material and an underlayment infrastructure positioned below the barrier layer. Included in the underlayment infrastructure are hat-shaped absorbing members that have a relatively compliant stage subsystem and one or more relatively stiff stage subsystems.

A methods of executing start, run, and stop sequences on a machine for converting a web of preformed pouches into inflated dunnage units. The pouches are defined by transverse seals extending from a remote edge to within a predetermined distance from an inflation edge.

A void-fill package, and method of making the same, comprising at least 50%, on a weight basis of the package, recycled polyethylene; at least 40%, on a weight basis of the package, virgin polyethylene; at least one moisture scavenger; and at least one melt stabilizer.

The invention relates to an extrusion blow-molded container, the inside of which is defined by a container side wall and a container bottom, a standing area being detachably connected to the container side wall and to the container bottom. According to the invention, at least a subarea of a bottom of a primary container product formed from the parison is irreversibly moved into the container such that an undercut container bottom is embodied on the container at least in a subarea, the standing area of the container being formed in the region of the undercut container bottom from a side wall of the primary container product by bending and/or pressing down.

Molded foam articles are provided. The molded foam articles have at least one surface having at least a portion that has been skin-formed for forming a skin-formed living hinge for enabling a robust living hinge capable of hundreds of open/close cycles at angles of up to 270.

An insulating bubble wrap comprising a metallized polyethylene layer having a first metallized side, a second non-metallized side, and a metal thickness; and a polyethylene bubble film cap layer attached to the metallized polyethylene along the second non-metallized side.

Disclosed are an inflation-free double-sided airbag and its preparation method. The inflation-free double-sided airbag includes upper airbags arranged into an array and connected to one another to form a planar body, lower airbags arranged into an array and connected to one another to form a planar body, an elastic layer disposed between the upper airbag and the lower airbag and having an upper surface connected to the upper airbag and a lower surface connected to the lower airbag, and a soft edge connecting portion disposed between two adjacent upper airbags and between two adjacent lower airbags. After the airbag is pierced, it still has the protection effect. When an external pressure is exerted onto the inflation-free double-sided airbag, the elastic material layer provides a buffering effect to minimize the degree of deformation of the airbags and reduce impacts on a user or a product.

A methods of executing start, run, and stop sequences on a machine for converting a web of preformed pouches into inflated dunnage units. The pouches are defined by transverse seals extending from a remote edge to within a predetermined distance from an inflation edge.

A surface underlayment system and its method of manufacture that is sandwiched between an impact-receiving upper surface and a lower foundation. The energy absorbing system has subassemblies of interconnected modules that cooperate to absorb and distribute impact forces applied thereto. Each module has one or more frustoconical support structures. At least some of the frustoconical support structures have bases that underlie the upper impact-receiving surface such as a golf putting green, a football field, marine decking, and senior living flooring.
