My "better half?" bought one of these cheap (~£20) small cold frames.
For planting out a pot of mixed lettuce from the supermarket it's OK.

It consists of panels of double skinned plastic extrusion glued into a
slot in an aluminium extrusion frame - and on one of the lid elements
this glue has failed. Can someone please make suggestions as what
glue would be suitable for this.

That depends upon the type of plastic, as the bond between that and the
adhesive is likely to be the weak point and different plastics have
different bond strengths to different adhesives. You might find an
aggressive double-sided adhesive tape, such as carpet fixing tape, better than a glue.

That's an excellent suggestion Colin. A few weeks ago I had to tow my
figure across Europe. Because the bucket sucks out behind the trailer it
haste have a long load triangle fitted. I got one in polycarbonate - the
same material used for cold frame glazing but it was floppy and folded up
when towed at 60. I got some aluminium track and bonded it to the plastic
using "Mammoth" tape. Like carpet tape but much stronger.

Clean the surfaces carefully (I used meths) apply the tape to one surface,
peel off the protection strip press into place. You only get one chance,
the bond is as strong as epoxy.

It's sold by Toolstation as "power grip tape" it is available in 25mm and
50mm widths in rolls of 2.5 metres for £2.50/£4.50 respectively.
