Abstract: A multi-layered pressure packaging comprises a first container including a lockable neck portion followed by a body part and a bottom part, obtained from a non-foamed thermoplastic material by stretch blow molding, and a first layer at least enclosing the body part and/or bottom part of the first container. The first layer comprises foamed material, and the foamed material layer is foamed in place with an outer enclosure applied over and around the first container defining a free space in between, and foamable material introduced and foamed between the first container and the outer enclosure in the free space, obtaining the foamed material layer. A second layer is applied on the outer surface of the foamed layer for keeping the foamed layer and the first container together. Methods are provided for manufacturing a multi-layered pressure packaging according to an embodiment.

Abstract: The invention provides a mould core and injection moulding apparatus for the production of a preform using a mould core which in the zone for defining the neck part of the preform comprises a combination of a raised portion and a shallow groove with a depth of 0.01 to 1 mm provided in the raised portion, for defining an internal attachment means in the neck of the preform. The invention also provides a preform and a container made from the preform, with internal attachment means in the neck. The internal attachment means is carried out rotation symmetrically with respect to the longitudinal axis of the preform. The combinations with an insert piece, preferably a pouring spout, flexible hose or dosing cap, have also been described. Furthermore, the invention provides an injection moulding method for the preform production and a stretch blow moulding method for the container production.

Abstract: A thermoplastic polyurethane obtained from a reaction mixture comprising: (a) at least one cyclic polyisocyanate, and (b) at least one polyol, in which the thermoplastic polyurethane has gas barrier characteristics which are better than the gas barrier characteristics of polyethylene terephthalate (PET) measured under the same circumstances, wherein the thermoplastic polyurethane is an essentially amorphous material based on the absence of a melting peak in a DSC curve, and the thermoplastic polyurethane has a glass transition temperature Tg situated between 60° C. and 99.5° C. in a DSC curve, and both curves were obtained with differential scanning calorimetry (DSC) as mentioned in the description. Hollow and hard bottles can be obtained from this material and as well as methods for obtaining the material and bottles.

Abstract: This invention relates to a polymer product comprising the components consisting of a polymer in form of granules; a multidimensional structure containing amphiphilic molecules, such as lipids, surfactants or polymers, wherein said polymer product has an active and/or passive oxygen or CO2 barrier, with an UV blocking activity or with potentially colouring with the incorporation of the multidimensional structure. It further relates to a method for manufacturing notably said polymer products, in particular from multidimensional aggregated components as barrier or carriers of living microbial cells and biological barriers in plastic and textile.
