Abstract: A method for forming an antislip material. A flexible thermoplastic carrier is provided. A hot release surface is provided. Provided is a first layer of discrete thermoplastic particles, sifting on the hot release surface. The discrete particles are above their softening temperatures, providing in the first layer a tackiness. The method includes contacting the carrier with the tacky first layer for sticking the first layer to the carrier, and thereafter removing the carrier, and therewith the tacky first layer stuck to the carrier, from the release surface. Thereby the carrier is provided with a hot, preferably discontinuous and/or elastomeric antislip coating. With a heat energy of the hot coating a bond is formed between the carrier and the coating. The removing of the carrier includes pulling the carrier out of the contact with a pulling-out force. The temperature of the hot release surface is above the melting temperature of the carrier.

Abstract: Methods of forming fasteners are disclosed. One method comprises dispersing polymer particles into a contact release surface, transforming the polymer particles into an at least semiliquid state of a suitable viscosity for a time sufficient to transform into preform projections having contact edges, contacting and fixing a front surface of the base with the terminal ends of at least some of the preform projections, removing the base, thereby separating the preform projections, from the release surface, and forming engaging projections projecting from the front surface of the base.

Abstract: The invention relates to packaging container, packaging method and system. The packaging container, comprises a flexible plastic wall (2) comprising one or more vents (5), the one or more vents (5) adapted to conduct gas (29) from an inside of the container into an air-channel (6) and from the air-channel (6) to an outside (7) of the container, having air-channel-walls defining the air-channel (6), comprising internal venting means (10) for conducting gas (29) from inside the container into the air-channel (6), at least partly defined by means of at least one sealed or glued seam (9) having in at least a partial region a reduced degree of bonding sufficient to allow gas (29) to escape in response to a suitable pressure.

Abstract: There is provided a fastener for engaging with a loop fabric, comprising a base having a front surface with a multiplicity of engaging projections. At least some of the engaging projections having a top surface end and an attached end. The at least some engaging projections top surface ends form an edge angle surrounding the projections. A mantle surface extending from the top surface end edge to the attached end. Generally at least one contour line of a side view of the mantle surface is convex.

Abstract: A method for treating a package. In the method a first plastic film sack (14) is provided, that has a flexible wall (18) comprising a plastic film (3), the wall (18) having an outer surface (5). A second plastic film sack is provided. A product of powder form is provided that has an upper size limit which is the particle size smaller than 1 mass-percent of the particles of the product of powder form, which upper size limit is at most 5000 microns and a lower size limit which is the particle size bigger than 1 mass-percent of the particles of the product of powder form. The product of powder form is packed in the first plastic film sack (14), and the first plastic film sack is, at least partly, placed upon the second plastic film sack.

Abstract: The invention relates to process for roughening thermoplastic films and roughed films. The invention further relates to process for preventing thermoplastic packaging films from slipping on each other and a suitable system for such purpose. The essence of the roughening process is that practicles consisting of the same polymer as that of the film and/or other plastic material being able to weld together with that, and having suitable size and/or abrasion resistance are brought to the surface to be roughened of semi-finished product having sufficient reserved heat content to maintain condition appropriate for welding said particles on said thermoplastic film surface to be roughened or on one or on both film surfaces being re-heated to such temperature and are dispersed in suitable closeness and configuration and that condition of the roughened surface is maintained until desired welding process is completed.
