A tissue paper package not prone to losing shape. Film-packaged tissue paper comprising a pop-up type substantially cuboid bundle of tissue paper packaged with a flexible resin packaging film, and characterized in that air vents for providing communication between the inside and the outside of the package are formed at positions on the packaging film facing short-side surfaces of the bundle of tissue paper where no folded edges are arranged.

A tamper-evident package utilizes a transparent resealable adhesive structure such as a tape or a label to cover the closure opening. Upon a first opening of the package frangible portions of the package front between adjacent disconnected arcuate cuts are torn. This results in a package which is visually tamper-evident after a first opening. A series of disconnected arcuate cuts comprising an apex and two free ends are arranged in laterally extending opposing top and bottom rows. In one case the cuts have portions of their distal free ends which overlap vertically and are parallel and aligned with the longitudinal axis of the package. The cuts are preferably centered laterally and are flanked on the right and left sides by two continuous wavy slits. One row of the cuts can comprise cup shaped cuts with a flat linear portion of each cut lying along its apex.

Disclosed herein are water-soluble films comprising a mixture of a water-soluble polyvinyl alcohol copolymer including an anionic monomer having a pendant carboxyl group, and a plasticizer blend comprising a first plasticizer comprising sorbitol and a secondary plasticizer selected from the group consisting of glycerol, trimethylolpropane, diglycerol, glycerol propylene oxide polymers, glycerol diacetate, 2-methyl-1,3-propanediol and a combination thereof, wherein (i) when the total plasticizer in the film is less than 12 PHR, then the plasticizer blend comprises sorbitol, glycerol, and at least one additional secondary plasticizer; (ii) when the total plasticizer in the film is at least 12 PHR and less than 20 PHR, then the plasticizer blend comprises sorbitol, glycerol, and at least one additional secondary plasticizer selected from diglycerol, trimethylolpropane and a combination thereof; and (iii) when the total plasticizer in the film is 20 PHR or greater, then sorbitol comprises at least of the total plasticizer.

The present invention relates to a laminated cellulose-based liquid or semi-liquid food packaging material, comprising a bulk layer from cellulose fluting material, an outside substrate layer having a print surface and on the inside an aluminium foil barrier and a further barrier layer. The invention further relates to the method for manufacturing the laminated packaging material and to a packaging container for liquid food packaging, comprising the laminated packaging material.

This disclosure describes example portable medical device protectors that may be used in combination with various antimicrobial and/or antiseptic agents to reduce contaminants on a portable medical device. According to some embodiments, the disclosure describes that the protectors may comprise an impermeable container to store a permeable applicator impregnated with an antimicrobial or antiseptic agent.

An oral pouch product having a soft edge includes an inner filling material enclosed inwardly of at least one seam between opposed layers of porous pouch wrapper. The at least one seam is separated from the periphery of the porous pouch wrapper by an unbonded area of the opposed layers so as to form a soft edge of the pouch wrapper.

A sonotrode and anvil are adapted for ultrasonic welding of work pieces, to produce a narrower weld region that exhibits greater durability, permitting use of less material per package. The horn-to-anvil contact is through a plurality of energy directors arranged into a three-dimensional grid pattern to be capable of distributed vibration-transmissive contact. The energy directors include a series of plateau surfaces regularly spaced apart in a first direction, and in a second direction that is orthogonal to the first direction, to form the grid pattern. The energy directors of the horn are configured to interlock with the energy directors of the anvil. The rectangular-shaped plateaus are spaced apart by angled side-surfaces that form valleys. A stepped transition to a corresponding region of reduced height for the energy directors of the sonotrode and anvil may form a cosmetic seal region with a lesser integrity, in addition to the main barrier seal.
