Tape for use in a freezer

not the answer you wanted, but I have generally found them not too expensive to replace

plastic cement will repair brittle styrene

I ended up stitching them together with cable ties. That's not very satisfactory either, because it's ugly and the ends of the ties bite you when you pick up the drawer, but I couldn't find anything else that worked.

Check the type of plastic, usually marked with a triangle and number or letters

Get a suitable glue for that type of plastic. Leave the trays out to warm up and dry off before gluing, has given me good results.

Dichloromethane or chloroform may solvent weld them.

Sticky tape strikes me as a pretty rubbish solution to the problem.

Find what plastic the trays are made of and it may be that there is a solvent glue which will effectively weld the cracks. If not then I think I'd either screw some 'patches' of sheet metal or plastic over them or I'd bind them together by drilling small holes and using cable ties.

bout 6 months ago I repaired one with some wide, clear, sticky tape that I had acquired from the pound shop

it's still holding

I have some which crack around the "handle" recess, and thick clear 50mm tape as sold for greenhouse repairs works fine. As would the aluminium tape, I suspect.

I also added some of those U shaped plastic binders they sell in stationers, for binding several sheets of A4 into a 'book' form, where they had cracked at the hand grip.

Those are dead handy, aren't they? I already repaired our fridge with one.

I always use superglue liberally.

I wouldn't want to use metal since the differential expansion/contraction rates would be a problem.

Yep - I reinforced all of the drawer molded in finger grips on our freezer, after three broke.

Thanks for all the suggestions - there are probably enough cracks in them for me to try all the solutions :( but initially I'll go for the Greenhouse repair tape.

I repaired a drawer that the wife dropped with araldite and some plastic strips cut from an asda gift card. Its still ok after two years.
