A deposition mask package according to the present embodiment includes a receiving portion, a lid portion that faces the receiving portion, a deposition mask that is arranged between the receiving portion and the lid portion and has an effective region in which a plurality of through-holes is formed. The receiving portion has a first opposing surface facing the lid portion and a concave portion provided on the first opposing surface. The concave portion is covered by a first flexible film. The effective region of the deposition mask is arranged on the concave portion with the first flexible film interposed therebetween.

A laminated foam sheet having a polyethylene resin foam layer and an antistatic polyethylene layer laminated on one or both sides thereof is produced by coextruding melts for respective layers, wherein the melt for the antistatic layer contains a polyethylene resin, an ionomer resin antistatic agent and a specific amount of volatile plasticizer blend containing an alcohol and a saturated hydrocarbon or a dialkyl ether. The antistatic layer of the obtained laminated foam sheet has specific morphology.

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.

The present disclosure relates to crush resistant packaging materials and/or constructions and to methods of making and using them. Many embodiments provide crush resistance in addition to customizability.

A multilayer corrugated board which can be smoothly bent from a planar state to a curved state without failure even at small radii of curvature, as well as a container made from such board. The materials and mechanical properties of the layers of the board are selected such that each layer inward of the outermost layer in the bent state buckles simultaneously and reversibly between each flute of the adjacent innermost corrugated layer.

The antistatic layer of the obtained laminated foam sheet has specific morphology.

The invention relates to a cover or case for goods, in particular for use as a cover or case for hobby or sports equipment. In an embodiment, the case has an inner portion, formed of expanded polypropylene (ePP) and defining a cavity for receiving at least part of the item. The case also includes an outer layer, formed of self-reinforcing polypropylene (srPP), arranged to cover an outer surface of at least part of the inner portion. In further embodiments, the cover is formed of two or more sections that may be arranged to at least partially overlap, wherein adjusting the overlap of the at least two sections changes the dimensions of an inner cavity within the cover or case. The case may be telescoping, in order to provide adjustable dimensions for a cavity within the case.

In the preferred embodiments, the present invention provides substantially improved slit sheet cushioning products by advantageously combining novel paper properties with novel slit patterns for improved features and characteristics. In some illustrative and non-limiting example embodiments, cushioning products of the present invention can include, e.g., a novel slit sheet material in combination with extensible paper employed as, e.g., a cushioning pad or as cushioning within an envelope product, wherein the cushioning product can be substantially more resilient, but, yet, e.g., thinner for better utilization of space.

A machine for making insulation may include two or more rotatory members configured to pull a precut insulation product at a first rate, wherein the precut insulation product comprises a first paper layer, a second paper layer, and a continuous paper core sheet, a first restraint and a second restraint spaced apart a predetermined distance to create a first space therebetween, and two or more second rotary members configured to feed a continuous paper sheet at a second rate into the first space such that the continuous paper sheet forms a plurality of flexible loops defining a plurality of air channels that extend in a direction that is substantially perpendicular with a machine direction. The first rate may be slower than the second rate.
