Manufacturer of plastic film. An extremely unscrupulous company. The purchased film with the stated thickness of 150 microns turned out to be only 100 microns. If you purchase a film from them, do not believe the stated thickness, but be interested in the weight of the roll and calculate the actual thickness. You will be unpleasantly surprised. Photo confirmation. Such a roll of 150mm film should weigh about 50 kg, but they have only 33.1 kg. That's sleight of hand and no cheating. "TU allows it."
