Abstract: A monitoring device for monitoring a screw joint of an object includes a base plate to be attached to the object and a top plate to be attached to one part of the screw joint, wherein the base plate and the top plate are positioned parallel to and on top of each other and wherein both plates each includes at least one electrode that capacitively interact with each other. The monitoring device is characterized in that the electrodes are shaped and positioned such that at least one electrode of one of the plates interacts with at least two different electrodes of the other one of the plates depending on the rotational position of the plates relative to each other. A monitoring arrangement having at least one monitoring device of this kind and a monitoring method are also provided.

Abstract: Rigid wadding, insulation and packaging for food and other products is made of homogeneous polyester terephthalate (PET) that satisfies the resin recycling identification code number one. For purposes of protecting an inner rigid wadding or other insulation, one or more film strips or film coatings may be applied by the artful use of amorphous (non-crystalized) PET that melts at a lower temperature and can act as a thermal bond adhesive. The film strips or film coatings may be made of homogeneous polyester terephthalate (PET) that satisfies the resin recycling identification code number one.
