In a bag with a jacket wall composed of at least two layers closed in each case by means of a longitudinal adhesive seam to form a tube and having two front ends, and with folded bottoms closing the bag at the front ends, and with a filling opening for introducing a filling material, wherein the jacket wall has at least one paper layer and the at least one paper layer at least largely determines the load-bearing capability with filled weight and the mechanical stability of the bag, the usefulness of the bag is improved by the fact that the jacket wall has, on its outside, a layer of a plastic film with a thickness of 60 pm or less, which surrounds the at least one paper layer and protects it from moisture and, in an area of overlapping ends, has adhesion points (K) between which air removal paths (Z) are formed.

The present invention relates to flexible double-bottom bags having an outer web which is folded upon itself to form a front panel and a back panel The outer web includes an inward-facing cross-sectional gusset opposite the open mouth of the bag and centered along the width of the bag joining the front panel to the back panel and creating an outer bottom portion of the bag. The bags also have an inner web which is folded upon itself to form a front panel and a back panel.

Polyarylene sulfide compositions are described that exhibit high strength and flexibility. Methods for forming the polyarylene sulfide compositions are also described. Formation methods include dynamic vulcanization of a polyarylene sulfide composition that includes an impact modifier dispersed throughout the polyarylene sulfide. A crosslinking agent is combined with the other components of the composition following dispersal of the impact modifier throughout the composition. The crosslinking agent reacts with the impact modifier to form crosslinks within and among the polymer chains of the impact modifier. The compositions can exhibit excellent physical characteristics at extreme temperatures and can be used to form, e.g., tubular member such as pipes and hoses and fibers.

The present invention is directed to a bag of polymeric film and a method to make the bag. The bag can be comprised of a front panel and a rear panel. The front and rear panels can each be comprised of multiple layers of film. The bag can be formed from a collapsed bubble of polymeric film that has been folded in half so that opposing edges of the collapsed bubble form an opening of the bag. One of the layers of the folded bubble can be split adjacent to an edge of the collapsed bubble and a draw tape film can be inserted between the layers of the folded and collapsed bubble. The collapsed bubble can further be embossed by a pattern that can provide enhanced properties to bags formed from the folded bubble.

The present invention refers to a bag suitable for containing cement, or other similar material, made up of at least two paper sheets superimposed on each other, with a weight of 70-90 g/m.sup.2, of the semi-extensible type, i.e. with a tensile strength in the machine direction MD of 6.4-7.8 kN/m and a tensile strength in the transverse direction TD of 4.7-5.8 kN/m measured according to ISO 1924-3:2019

Each of said outer paper sheet and internal paper sheet is coated on one side with a water vapor barrier layer having a weight of 10-20 g/m.sup.2 measured according to the ISO 536:2019 standard,

The barrier layer comprises a styrene-based polymer dispersion and at least one pigment composed of clay and calcium carbonate.

The water vapor barrier layer is in turn coated with at least one hydrophobic paint layer of the water-based wax type, such as for example a polymeric wax, including at least one element of the isothiazol-3-one type, such as example 1,2-benzisothiazol-3 (2H)-one, 5-chloro-2-methyl-2H-isothiazol-3-one (CMIT) and/or 2-methyl-2H-isothiazol-3-one, and mixtures thereof.

In this way, both the transmission of humidity/water vapor (WVTR) and the absorption of water (COBB) are significantly reduced.

In fact, thanks to the water vapor barrier layer and the hydrophobic paint layer applied on it, the water is not retained by the paper, but slides away due to the high surface tension present on the treated paper.

The bag achieves these results despite having no intermediate plastic layers.

A bag includes an interior pocket and an exterior pocket. The interior pocket is attached to a wall of the bag along a seam that is stitched across a width of the wall. The seam is located at a height from a bottom of the wall. The exterior pocket is attached to the bottom of the wall of the bag and has a top edge extending across the width of the wall. The top edge of the exterior pocket is located a height from the bottom of the wall. The height of the top edge of the exterior pocket is greater than the height of the seam of the interior pocket.

The disclosure is directed to sampling bags having flexible walls. The sampling bags may have agile walls that include a shape memory component. The shape memory component tends to return the sampling bag to its initial shape. Such sampling bags may be used in a variety of sampling methods.

A fruit bag having a body and an entrance formed on the body to insert young fruit thereinto, the body having a front surface, a back surface, and side surfaces is provided. The fruit bag includes: a cover protruding from the front surface to cover the entrance; multiple folding portions formed by folding each side surface at least one or more times; and an opening part attached to the form of a band to the end portion of the body forming the entrance and having flat portions attached to the front surface and the back surface and grasping portions attached to the side surfaces, the grasping portions forming hinges together with the multiple folding portions so that if a pressure is applied to the grasping portions, the entrance is expanded by means of the flat portions.

The purpose of the present invention is to provide: a container in which a cellulose resin composition can be stored without discoloring with the lapse of time; a package comprising a cellulose resin composition and the container; a method in which a cellulose resin composition is inhibited from discoloring by using the container; and a method for producing a molded resin object, the method including using the container. The container, which is for containing a cellulose resin composition comprising a thermoplastic resin and cellulose, includes a high-lignin-content member, which has a lignin content of 10 mass % or higher, and a low-lignin-content member, which has a lignin content of 1 mass % or less, and has a surface to be in contact with the cellulose resin composition, the whole of the surface being constituted of the low-lignin-content member.

A multi-sheet bag includes an inner sheet having a film side defining an interior surface of the multi-sheet bag; an outer sheet coupled to the inner sheet on a side opposite the film side; at least one void disposed between the inner sheet and the outer sheet defined by an adhesive pattern deposited between the inner sheet and the outer sheet.
