[chbot] Polishing 'Sistema' box lid

[edwardsw at steadfast.co.nz]

Hi Robin

All of my Sistema Klip It food storage boxes are marked on the bottom of the box with recycling symbol "5" and "PP" so they are made of polypropylene.  Sistema do various products including ones intended for the microwave, and they may have different plastic.

Curiously, none of my Sistema boxes have the lettering on the lid - perhaps that is a recent addition, or its only on the smaller boxes?  Larger boxes on the warehouse website don't have the embossed logo on the lid.

If you can't polish the logo off, perhaps you could cut out a section of the lid and glue in a sheet of acrylic instead, but from memory one downside of PP is finding an adhesives that will stick to it, but it can be welded.  You may get epoxy or hot glue to work if you roughen the surface and don't put a lot of load on it.  An advantage of acrylic is that it is more scratch-resistant than PP.

This one is close enough and illustrates the lettering.

Apart from the price, the availability is a feature as any Warehouse has them. Also being able to pick it up and put a tape measure to ALL the dimensions means I can get something that fits (or one that fits in
another!)
