DO NOT DO THIS to an unknown plastic.  Some plastics give off cyanide  gas.

The 4  mil clear plastic sheet is very likely to be made from 
polyethylene.   That is the cheapest and most common type.  It is pretty 
close to  impossible to glue solidly to polyethylene.  Solvent based 
contact  cement may have a chance.

To tell if it is polyethylene, light a small  scrap on fire and take a 
small sniff of the smoke.  If it smells like  a really cheap candle 
burning (paraffin wax, not beeswax or stearin from  animal fat) then it 
is polyethylene.  If the odor is sharp and acrid  and makes you cough, 
then it is likely to be polyvinyl chloride  (PVC).  If it smells similar 
to burning hair, it is one of the nylon  family.  (Nylon is not too 
likely as a consumer grade film in large  sizes.)

If, per chance, it is PVC, you might be able to glue it with  the glue 
used to make joints with PVC pipe.
