We feel that this absolutely lightproof black and white film from Easy Grow Films is the best black and white film on the market!
This film is white on one side so that the light is reflected well and black on the other side so that no light from outside penetrates! Or no light penetrates to the outside. Just 100% Lighttite. Maybe this film is a bit more expensive than other black and white films. However, thanks to the production in England, the process and the raw materials are known. Easy Grow Reflectives is known for food-repellent, plasticizer-free, durable and heat-resistant reflective films. Be careful with cheap copies, because they may contain plasticizers. Plasticizers are suspected of causing cancer.

The foil is 125mü thicker than other black/white foils.

The thickness and durability of this film make it ideal for separating rooms or attaching it to roof battens or walls.
