Abstract: The invention is a flexible packaging material having a narrow band of pressure sensitive adhesive beneath a heatsealable surface layer. When the material is formed into a package, a heatseal is formed along the band of pressure sensitive adhesive. When the heatseal is opened, the pressure sensitive adhesive becomes exposed at the surface of the seal, which enables the package to be resealed by manual pressure alone. A particular advantage of the invention is that the pressure sensitive adhesive is present only in the narrow band, where it is needed to form the resealable seal. The packaging material is made by side-by-side coextrusion.

Abstract: A rotating mold is fed with a flowable mixture of an inorganic filler material powder and a polyester resin for the purpose of generating or building up individual layers. By selecting the rotating speed during the layer buildup a more or less pronounced separation between resin and filler material is produced inside the layer, the value of the separation being selected in accordance with the specific application the component produced is intended to be used for. Subsequently the layer is fed cut glass fibers made to penetrate at least into the innermost resin-enriched region of the generated layer. Owing to this rotational-speed-controlled distribution of fiber material and resin inside the layers, larger values of mechanical strength may be obtained with reduced glass requirements. Any "strain-corrosion" may be avoided by using filler materials containing carbonate.

Abstract: A thickness-reduced deep-draw-formed can obtained by using, as the substrate, a cold-rolled steel plate having a carbon content in the steel of 0.02 to 0.15% by weight, a manganese content in the steel of 0.2 to 1.0% by weight, a mean diameter of crystal grain of smaller than 6.0 .mu.m, a tensile strength over a range of from 35 to 55 kg/mm.sup.2, and a thickness of 0.17 to 0.30 mm in a step of subjecting an organic resin-coated structure of the surface-treated steel plate to the thickness-reducing deep-draw forming. This makes it possible to suppress the generation and accumulation of heat in the organic resin-coated steel plate to a level lower than the conventional levels. Therefore, the organic resin coating is prevented from being peeled off or damaged and, as a result, the corrosion resistance can be markedly improved.
