Abstract: The invention concerns a deep-drawn paper tray (4), particularly a shallow tray made of paperboard or cardboard, a method and an apparatus for manufacturing such a tray by deep-drawing techniques, and a closed product package comprising the tray of the invention, particularly a heat-sealed gas- and liquid-tight food package. The tray comprises a bottom (4a) and upwardly expanding side walls around the bottom, the side walls of the tray being shaped to expand through a plurality of circumferential steps (4b, 4c, 4d) dimensioned low enough for obtaining wrinkle-free side walls for the tray. The outermost step is a flat, wrinkle-free rim flange (4d), which enables liquid and gas proof heat-sealing of a lid to form the package. The apparatus according to the invention may comprise upper and lower moulding tools (10, 11) with concentric movable frames (10b, 10c, 10d) for forming the tray bottom and side wall steps to paper blanks, and moulding tools (10) may be mounted onto a rotating turret (9) carrying a paper blank through working stations arranged along the turret circumference, to shape the tray bottom and the side wall steps at the consecutive stations.

Abstract: The invention relates to a method of deoxygenation of tall oil as well as methods for the production of aliphatic hydrocarbons and polymerizable monomers from tall oil. Sulphurous crude tall oil (5) together with hydrogen gas (6) is fed into a reactor (1) comprising a catalyst bed (2, 3). The oil is catalytically deoxygenated by hydrogen in the bed by use of a sulfided metal catalyst, e.g. a Ni-MoS catalyst. The flow exiting the reactor is cooled down and a hydrocarbon-bearing liquid phase (10) is separated from a gas phase (18), followed by subjecting the liquid phase to distillation (14) for removal of useless aromatic hydrocarbons and then to steam cracking (4) to form a product containing olefins such as ethylene or propylene. By regulation of the deoxygenation temperature to be at least 270°C but less than 360°C the yield is rich in linear and cyclic aliphates that usefully turn to olefins in the steam cracking, while formation of napthalenes is reduced.

Abstract: The invention relates to use of polylactide (PLA) as an extruded polymer coating on paper or board intended for the production of containers and packages, which are heated in a stove or microwave oven. According to the invention a polyfunctional cross-linking agent, such as trialkyl isocyanureate (TAIC), is blended with PLA, and the extruded coating layer is subjected to cross-linking electron beam (EB) radiation. PLA may be used as such or blended with another biodegradable polyester such as polybutylene succinate (PBS). EB radiation has been found to improve adhesion of the coating to the paper or board substrate, heat-sealability of the coating, and heat- resistance of the finished containers and packages.
