    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, sitting 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. The carrier would be spoiled, if heated completely to the temperature of the release surface and simultaneously pulled with the pulling-out force. Therefore the contacting time is kept shorter than a minimum time required by a heat of the hot release surface for spoiling the carrier. Flat-topped roughening projections can be included in the antislip coating.

    Abstract: An antislip, heat sealable plastic packaging bag, is formed from an antislip flexible packaging material whose wall has an average surface weight of at most 500 g/m2. The packaging material includes a multiplicity of randomly distributed, separate antislip protrusions of a first substance. The protrusion height is between 50 micrometres and 10000 micrometres, with an average of top-plan-view aspect ratios of the antislip protrusions being at most 5.0. Some antislip protrusions have a hidden surface portion being a portion of a free surface of the antislip protrusion, which the antislip protrusion covers from a viewer in a top plan view of the wall. The first substance is a thermoplastic polymer, and the wall's outer surface is of a substance at least somewhat different from the first substance. It is an important feature that the first substance has a melt mass flow rate of at least 0.6 g/10 min. An apparatus, for producing the packaging material, includes a film blowing die head, a cooling air ring, and a particle dispersing unit therebetween, for dispersing polymer particles on the bubble neck at a place in, or closely under, an expanding area where the bubble has a divergent shape.

    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. The carrier would be spoiled, if heated completely to the temperature of the release surface and simultaneously pulled with the pulling-out force. Therefore the contacting time is kept shorter than a minimum time required by a heat of the hot release surface for spoiling the carrier. Flat-topped roughening projections can be included in the antislip coating.

    Abstract: A stackable package includes a packaging sack and a block of plate-frozen fish packed therein. The sack is a plastic sack having a second outer surface, on which the package can be laid on a stack, and an opposing first outer surface. A roughened surface-part of the first outer surface includes antislip protrusions projecting from a first wall of the sack. A skidproofed surface-part of the second outer surface includes a skidproofing material, of a suitable fibrous structure, fixed to a second wall of the sack. The skidproofing material is capable of a nonslip bond with the antislip protrusions. The sack has a wear rate of between 0 and 0.35. The wear rate is determined in a wear-rate test in which (at a temperature of −20° C. and a compression of 11557 Pa) a specimen of the skidproofed surface-part is slided on a roughened surface-part specimen and the wear rate is defined as the proportion of the number of anstislip protrusions breaking off the roughened surface-part specimen due to the slide. Accordingly, multiple packages can be manually re-stacked without losing too many of their antislip protrusions.
