The role of vacuum packaging color printing for food packaging bags
Most of the food packaging bags contain various patterns and characters, which are completed by a thermal transfer process. Most of the processes are now done by mechanical equipment. There are few places that require manual operation, and insufficient pressure on the mechanical equipment may cause problems. Pressure refers to the force of printing various patterns on the food packaging bag. This force can be large or small. If it is too small, the pattern will not be clear, and it will be easy to appear color or fall off. If it is too big, it will be This causes the bag to be uneven, affecting its feel and aesthetics. If adjusting the proper pressure is the key to production, the pressure of the bags of different materials and different patterns is different, which requires long-term production and testing by the operator. The exact value is obtained, and this value is gradually adjusted during the use of mechanical equipment the day after tomorrow.
