Orca grow film 1 37m x 10m orca grow film is made from threads of a high density specialised reflective plastic which are bonded together creating a unique surface topography the resulting geometry of the microfibres and the submicron pores within the microfibre create a highly reflective and diffuse surface the same principal is found in snowflakes where normally transparent water is transformed into reflective bright white snow through the unique geometry of ice crystal formation dif
