Packaging comprising: a housing for containing products, said housing comprising an opening arranged to allow access to such products; a lid movable with respect to the housing between a closed position in which said lid prevents access to said opening and an open position in which the opening is accessible; magnetic closing components arranged to hold the lid in the closed position by magnetic force; said magnetic closing components are provided by a first magnetic component comprised in the housing and a second magnetic component comprised in the lid, said first and second magnetic components being at least partly located in regions of the housing and lid respectively which overlap in the closed position; wherein: the housing and the lid are formed respectively by folding of at least one blank of sheet material; and the magnetic closing components are printed/coated onto at least one surface of the sheet material; the packaging being characterised in that : at least one of the magnetic closing components has a surface magnetic field strength of at least 15 mT, whereby a direct pull force to surface area ratio required to separate the magnetic closing components from one another, with the force being applied perpendicular to contacting surfaces of the magnetic closing components, is at least 490.637 N/m 2 ; at least one of the magnetic closing components has a surface magnetic field strength of at least 15 mT, whereby a shear force to surface area ratio required to separate the magnetic closing components from one another, with the force being applied parallel to contacting surfaces of the magnetic closing components, is at least 490.637 N/m 2 ; and the first and second magnetic components have a total surface area of at least 2 cm 2 , preferably between 4 and 10 cm 2 , still preferably between 4 and 8 cm 2 . a housing for containing products, said housing comprising an opening arranged to allow access to such products; a lid movable with respect to the housing between a closed position in which said lid prevents access to said opening and an open position in which the opening is accessible; magnetic closing components arranged to hold the lid in the closed position by magnetic force; said magnetic closing components are provided by a first magnetic component comprised in the housing and a second magnetic component comprised in the lid, said first and second magnetic components being at least partly located in regions of the housing and lid respectively which overlap in the closed position; wherein: the housing and the lid are formed respectively by folding of at least one blank of sheet material; and the magnetic closing components are printed/coated onto at least one surface of the sheet material; the housing and the lid are formed respectively by folding of at least one blank of sheet material; and the magnetic closing components are printed/coated onto at least one surface of the sheet material; the packaging being characterised in that : at least one of the magnetic closing components has a surface magnetic field strength of at least 15 mT, whereby a direct pull force to surface area ratio required to separate the magnetic closing components from one another, with the force being applied perpendicular to contacting surfaces of the magnetic closing components, is at least 490.637 N/m 2 ; at least one of the magnetic closing components has a surface magnetic field strength of at least 15 mT, whereby a shear force to surface area ratio required to separate the magnetic closing components from one another, with the force being applied parallel to contacting surfaces of the magnetic closing components, is at least 490.637 N/m 2 ; and the first and second magnetic components have a total surface area of at least 2 cm 2 , preferably between 4 and 10 cm 2 , still preferably between 4 and 8 cm 2 . <EOS>
