Flexible multilayer laminates may have an improved integrated, one-way pressure-release valve for use in a sealed container for packing gas-producing products. The pressure-release valve is partly disconnected from the rest of the laminate, forming an inflatable outlet tube with at least one large outlet opening and lifting off from the laminate under increased pressure in the pack. The one-way pressure-release valve allows for pressure-release at low minimum opening pressure in a reliable and reproducible way.

A flexible, two-part bag. The bag has a first outer section for containing common toiletry items, such as toothpaste, toothbrush, floss, etc., including a small shovel, clean toilet paper, or package of moist wipes etc. The walls of the first outer section are preferably of transparent material or netting material to enable viewing of the contents. A second center section, formed inside the first outer section, and extending slightly above the first section, enables the contents of the sections to be separated, such that the bag forms at least two compartments.

One pouch for storage of multiple components of a mixture is described with a first compartment and a second compartment. At least one channel is defined between the first compartment and the second compartment and at least one seal is installed within the channel. Method of use the pouch includes: locating the channel; breaking the seal; and mixing the contents in the first and second compartment.

The present invention discloses a method for preparing a paper band that incorporates a composite paper mesh, intended for the manufacture of bags for horticultural products, wherein the embodiment of the composite mesh comprises a process that includes dividing a paper reel (1) into continuous longitudinal strips (2-5), transversely segmenting a paper reel (6) to prepare cross pieces (7) which are applied on two longitudinal strips (2-5) parallel and spaced apart from each other, in successively distant positions along said strips and bonded by gluing, and applying on the support base grid structure thus obtained a mesh (10) of paper yarn which is joined to the support base by gluing, and that can be divided into portions that can be used for covering windows or openings included in the paper band, all this with the aid of automated means.

A tamper evident bag has front and rear panels connected together along opposite first and second side edge margins and a bottom edge margins that define a bag interior and a first bag opening therebetween. The first and second side edge margins include first and second peripheral side edges. The front and rear panels each have a tear line with a first end and a second end, the first and second ends being adjacent to and spaced apart from the first peripheral side edge. The first and second ends of each tear line being spaced part. The tear lines extend over the front and rear panels but remain spaced from the second side edge margin. Each tear line defines a respective tear out section on the front and rear panels. The tear out sections are joined along the first side edge margin and are configured to be removed to create a second bag opening.

The present application is directed to a packaging for a powdered explosive-detection training aid which may include first and second opposing flexible sheets heat sealed together along less than a periphery thereof and defining a storage compartment therebetween, wherein an unsealed portion of the periphery defines an opening to the storage compartment, wherein at least a portion of the first opposing flexible sheet is a semipermeable material permeable to a vapor emitted from the powdered explosive-detection training aid, with the second opposing flexible sheet being impermeable to the powdered explosive-detection training aid vapor; and a sealing member, wherein the sealing member is secured to the first opposing flexible sheet and, in a closing position, covers the semipermeable portion of the first opposing flexible sheet.
