Abstract: The present invention relates to a sustainable article for packaging which could be made substantially free of virgin petroleum-based compounds; in particular it relates to new packaging made from coloured post-consumer resin (PCR) having a high NIR absorption. A need remains to create a circular economy for coloured and/or black plastic by bringing the waste coloured and black plastic into new packaging while using Near infrared (NIR) detectable pigment in the colourant masterbatch. It is therefore an object of the present invention to bring the coloured or black plastic waste into new packaging. It has be found that a sustainable packaging in consumer acceptable black using NIR detectable pigment can be obtained by using a multilayer post-consumer resin, comprising a thinner outer layer of post-consumer resin of natural plastic waste (N-PCR); and a thicker inner layer comprising at least 50% coloured plastic waste (J-PCR).

Abstract: A sander according to the present application provides a sander with a rotatable plate which can be locked by hand. Specifically, the sander of the present application has a main body and a sanding head mounted below the main body. The main body has a housing, a motor and a coupling mechanism contained in the housing. The sanding head has a sanding plate rotatably connected to the base plate and the base plate and/or the sanding plate may be connected to the coupling mechanism. The base plate may also have a locking means to lock the sanding plate. The sanding head of the present application may also have a rotatable sanding plate to allow for more efficient use of the sanding paper and a locking means that can be used to lock the sanding plate to provide simpler, easier and more reliable manual locking.
