Hello -
Thar she blows! I found the plastic tray website :
polarplastic.ca :: Rigid Trays
This is the exact tray I got :
CATERLINE - 16" Round platter
Code:
Polar Code: A716PBL25
Colour: Black
Case Pack: 25
UPC: NA
SCC: 0073773425031 8
Length: 415.9 mm
Width: 415.9 mm
Height: 108.0 mm
Cube: 0.0187 m3
Weight: 6.805 kg
Mfg Ref. Code: 383171
Material: Polystyrene
So now I know it's made of
polystyrene.
Ha ha, you can even get it in Eco-Green :
But this doesn't directly help us because it's not a site that sells individual trays. It's just the origin of the tray.
