6mm "panda film" is pretty inexpensive on eeb ay.

white on one side, black on the other.

NO light will get through it, unless a seam where it overlapped isnt taped shut.

unless you have help, the 5 foot wide roll is easiest to handle (versus 10 foot wide.

if used on the floor also, and all seams secured, it can turn any area into a "tent".

filter the intake, and never enter area without being perfectly clean, and use "area only" clothing and footwear to keep out the borg (spidermite).

treat it like a laboratory. get a white lab suit for entering your area.
haole007 Reviewed by haole007 on . is Panda film light proof? I had the idea for a cabinet to basically make a "bag" inside the cabinet. it would simply line the walls and be completely sealed (like one continuous piece) with a zipper door in the front. I guess like a tent within the actual cabinet. Question is, if the film is sealed is it thick enough to be lightproof? If not is there anything that is? thanks. Rating: 5
