Abstract: The present disclosure relates to a low-voltage electron-beam sterilizable polyolefin film of a polyolefin composition, for use in laminated packaging materials for liquid food products, the polyolefin composition comprising one or more polyolefins, characterized in that the polyolefin composition further comprises an antioxidant formulation comprising an N,N-dialkyl-hydroxylamine and a sterically hindered phenolic compound. The disclosure also relates to a low-voltage electron-beam sterilizable laminated packaging material for liquid food products comprising the low-voltage electron-beam sterilizable polyolefin film, to a packaging container for liquid food products comprising the low-voltage electron-beam sterilizable laminated packaging material and to a use of the low-voltage electron-beam resistant laminated packaging material in a method of forming, filling and sealing packaging containers for liquid food products.

Abstract: A number of pre-production calibration tightenings are performed at a screw joint identical to a screw joint used in production and using the same impulse wrench as to be used in production tightening. The value of one or more tightening related parameters are registered at the attainment of the desired pre-tension level, and those parameter values are used to statistically form a basis for a reference set-up. The tightening parameter values registered during production tightening are compared to the reference set-up, and an indication is obtained as to discrepancies between the reference set-up and the actually registered parameter values to get an indication as to whether the impulse wrench is malfunctioning and/or the screw joint is faulty.
