A mouth tape for promoting nasal breathing during sleep comprises a non-woven fabric substrate with an adhesive surface for adhering to perioral skin, and an integrated silicone gel section with a gentle adhesive surface for contacting the lips. The silicone gel section is positioned within the non-woven fabric substrate, creating a configuration where sensitive lip tissue contacts only the gentle silicone gel while the stronger adhesive of the non-woven fabric provides secure attachment to less sensitive perioral skin. This design maintains mouth closure throughout sleep while allowing trauma-free removal upon waking. Included ventilation features enhance user comfort. The invention solves the long-standing problem of balancing secure adhesion with gentle removal in mouth tape applications.

The present invention relates to a packaging material for use in a pouched product for oral use in order to enclose a filling material. The packaging material is a saliva-permeable nonwoven material comprising fibres. The packaging material is a wetlaid nonwoven material, or, alternatively, the fibres are carded and the nonwoven material is hydroentangled, or, alternatively, the fibres are carded and the packaging material has a basis weight 30 g/m.sup.2. 50%-100% of the fibres are cellulose-based staple fibres, and 0%-50% of the fibres are thermoplastic fibres, with % numbers being based on total weight of fibres at 21 C. and 50% RH. The packaging material further comprising at least 10% of a binder, taken as a wt % of a total weight of the packaging material. The present invention also relates to a pouched product for oral use comprising such a packaging material. The present invention further relates to a method for manufacturing of a packaging material for a pouched product for oral use.

A meltblown material formed from bicomponent fibers that can withstand the effects of a gamma irradiation sterilization process without negatively impacting bacterial filtration, particulate filtration, and/or breathability of personal protective equipment products formed from the meltblown material (e.g., facemasks, surgical gowns, surgical caps, etc.) is provided. The bicomponent fibers include a polyolefin-based sheath and a polyester-based core. Further, both the sheath and core include specific antioxidants and charge enhancer packages that allow for the effective electret treatment of the resulting meltblown material prior to sterilization, where the filtration efficiency and pressure differential of the material are still adequate post-sterilization.

Systems, devices and methods are provided for producing fibrous materials and products, such as filters. A system comprises a first device for generating one or more fiber stream(s), and a second device for isolating nanoparticles within a gaseous medium. The second device forms the nanoparticles into a stream and feeds this stream into the fiber streams to form the fibrous material. This distributes the nanoparticles more uniformly throughout the fibrous material. In addition, the nanoparticles increase the overall surface area within the material, which, in certain applications, increases its filtration efficiency and allows for the capture of submicron contaminants without significantly compromising other factors, such as pressure drop through the filter. Filters produced with these systems and methods are capable of withstanding rigorous conditioning, which allows the filter to achieve substantially the same level of filtration performance throughout the lifetime of the filter.
