The plate making process of the solid resin plate of the food packaging bag manufacturer is basically the same as that of the liquid resin plate, which also needs to go through the process of exposure, clearance, drying and post exposure, but there is an additional process of thermal curing. 1. Exposure. The exposure is carried out in the printer. Close contact the positive negative image with the resin plate and expose it. Generally, choose a low power light cooler with rich ultraviolet rays. 2. Drying and post exposure. 3. Rinsing: Rinse with warm water at a temperature of 45~50 ° C in the rinser. The water pressure is generally controlled at 2~2.5kgf/c. 4. The solid resin of the heat cured food packaging bag manufacturer is a pre coated plate with good flatness and stable size, which can be used to make a screen pattern. Although the process is simple, the cost is higher than that of the liquid resin version. The manufacturer of food packaging bags has solid resin and pre coated plates, which are fixed on the metal sheet base or polyester film base with good flatness. They are pre coated plates, which are fixed on the metal sheet base or polyester film base. They have good shrinkage, stable size, and high quality. They can be used to make a screen pattern. Photosensitive nylon plate, due to amide in nylon molecules and hydrogen bond between molecules.
