Austria found a way to increase the pressure resistance of cans for food packaging.
This method is to add some liquid nitrogen in cans filled with food. When liquid nitrogen evaporates, nitrogen can produce more pressure inside the can, which can improve the anti-impact ability of cans and reduce the damage of cans under pressure. Nitrogen can also extrude part of the oxygen in the can, which can prevent the oxidative deterioration of the food in the can.
The designer fully draws on the international popular factors, and the streamlined design has created a precedent for the shape of the copy table. The most advanced LCD backlight technology is adopted, and high-brightness and energy-saving LED (light emitting diode) is used as the light source, so that the light uniformity and brightness of this product are qualitatively improved compared with the traditional copy table, and the display effect can be similar to that of the LCD comparable.
