I am a final year student studying commerce at N.U.I Galway (Ireland). As part of our course work we must undertake an enterprise planning project. Our project is based on an innovative drinks tray made out of hard,durable,light,cheap plastic. Its dimensions are 1' * 1' rectangular or 1' diameter in circular shape. This tray would contain 6 holes in it. For our project we must find outr what is the best plastic to use and approximately how much it would cost to make a bacth of 200,000 of these trays. Our group would be very grateful for any information that you could provide us with. Thanking you in advance.
