Unfortunately, what seems to have happened is that the temperature of
the tray on which I placed the packs, ended up significantly higher
than the air temperature in the oven (not surprising since a lot of
the heat is radiated from the heating coils). The plastic packets
melted wherever they touched the tray, on the lower of the two trays
in the oven.


Or alternatively take the silica gel out of the assorted paper, plastic
and other packets, and dry it loose en-masse.

Then repack it into a re-usable/re-sealable cloth bag to contain it, and
yet allow passage of moisture into the crystals.


Thats what I do. A large ex-pickle jar with bulk activated cilica gel
crystals, slightly buff colour , not pure white.
Then cut off the inside pocket cloth of worn trousers before dumping ,
tied off with crystals in, when required
