The present disclosure providing a cushion pad includes at least one cushion unit including at least one die-cutting region, a length of the die-cutting region increased when the die-cutting region is unfolded; the die-cutting region is unfolded to form a buffer layer that causes the second surface to expand in a thickness direction of the second surface to play a buffering and protective role thereof; the die-cutting region is unfolded to form a three-dimensional network structure. The present disclosure also provides that a packaging bag with the cushion unit is of a plane structure after production; when the packaging bag is used after being transportation, an object is put into the packaging bag or applying a pushing force to the packaging bag so that the cushion unit is expanded to form the buffer layer, to protect the object inside the packaging bag.

A pinch bottom sack fillable with bulk good includes a sleeve with at least one area element, wherein the sleeve includes a mesh and the area element a handle means including a load element at which a load force is applicable for lifting the sack, and the load element is configured such that it extends at least in some areas at least in a load condition in which the load force acts at the load element opposite to an outer side of the area element.

An object of the present invention is to ensure rigid formation of the folds of the protrusions of the paper sheet and smooth conveyance of the folding-processed paper sheet to the downstream side of the folding position in the paper conveyance direction without causing the problems such as jamming. A folding unit includes a lower guide plate arranged at a position facing a folding plate at the folding position, and an arrangement position of a turning shaft of the folding plate is vertically movable with respect to the lower guide plate.

Disclosed are embodiments of a volume control storage bag and methods of making same. The volume control storage bag may have first and second sidewalls, a double-locking closure mechanism with a first closure element extending along the first sidewall and a second closure element extending along the second sidewall, each closure element having a channel and an elongated member configured for interlocking with one another. A gusset is sealed along three sides of the first and second sidewalls, leaving an opening through the closure mechanism and defining an interior space having a specific volume. Corner seals may be formed at the corners of the first and second sidewalls, further reinforcing the double-locking closure mechanism for an airtight and hence waterproof seal. The volume control storage bag may be made of a food-grade polyethylene vinyl acetate blend, approximately 90% or less ethylene vinyl acetate and approximately 10% or less polyethylene.

A first sheet panel is folded along a first fold line, and thereby a first folded part is formed in the first sheet panel. Subsequently, the first folded part is folded back along a second fold line, and thereby a folded-back part is formed in the first sheet panel. A corner cut device cuts a second sheet panel and the folded-back part to form corner cut parts. At this time, the corner cut device prevents the first folded part and a base part of the first sheet panel from being cut.

The invention relates to a valve bag, in particular a cross-bottom valve bag, comprising a first wall and a second wall, which are joined to each other by means of side edges or side folds and by means of bottoms and which delimit a bag interior, comprising a valve, which is arranged in one of the bottoms and via which the bag interior can be filled with a filling material, and comprising venting openings in the first and/or in the second wall for venting the bag interior. At least one channel is provided on the outside of at least one wall, which channel covers the venting openings and is formed at least by two parallel fastening strips and by a cover strip, the cover strip likewise comprising venting openings, and wherein the shortest path between the parallel fastening strips along the cover strip is longer than the shortest path along the at least one wall or the cover strip, and/or the parallel fastening strips consist of stretchable material.
