FIELD: transport, package.
SUBSTANCE: invention relates to system of producing laminar plastic, packing device to produce laminar plastic and method to produce packages made from packing laminar plastic. Laminar plastic comprises layer of particles that can be magnetised. System comprises at least one magnetisation appliance to apply magnetic field to magnetise certain amount of magnetic particles in forming magnetic mark in packing laminar plastic indicating damage location, for example joint or single local defect. System comprises scanner to detect damages and activate first magnetisation appliance on revealing damage for forming magnetic mark indicating damage location. Packing device comprises magnetic pickup to perceive magnetic marks indicating damage location of package or packing laminar plastic. Method consists in applying magnetic field for forming at least one magnetic mark in packing laminar plastic to mark location of damage and perceive the presence of at least one magnetic mark indicating damage.
EFFECT: efficient detection of damages in packing material.
