Line soft plastic packaging membrane production needs precautions.packaging kraft paper pouch

During the production process of liquid packaging bags, the membrane changes are relatively frequent, which can easily cause the film's performance. Due to the lack of ink volume in the liquid bag, the use of old ink printing for a long time may bring the problem of decline in ink performance. Therefore, there are many variable factors for liquid packaging production. Caiyin companies can formulate a suitable set of finished product testing standards through the conditions of the use of customers to ensure that unqualified products do not leave the factory and avoid unnecessary losses.

1. Choose the right material and equipment consumables

In actual production, the appropriate film and ink should be selected according to the specific conditions of the irrigation speed, sterilization conditions, and the length of the product shelf life of the automatic irrigation machine, and adjust and control the printing process parameters according to the actual situation, standardize the process process, ensure that the process process is to ensure that it is guaranteed to ensure that it is guaranteed to ensure that it is guaranteed to ensure that The printing quality of the film.

2. Customer post -processing conditions or test standards

The color print manufacturers can be targeted only by fully understanding the conditions of food manufacturers during the filling and the process of subsequent processing, and even the details of liquid bags in the market circulation links, and count in the hearts of equipment consumables. The main attention points include: filling speed, sterilization conditions, long and short shelf life, preservation requirements, etc.

3. Requirements for printing technology

During the printing process, we must pay attention to the control of the process conditions such as printing tension, printing pressure, printing speed, and drying temperature, formulate a set of stable and reliable process standards, standardize process processes, and ensure the smooth progress of scale production. In addition, the comprehensive quality of printed workers, the technical materials provided by ink manufacturers, the quality of the dilute materials, the changes in the workshop environment, etc. are also factor that cannot be ignored.

4. Control the printing environment well

Too dry environment in the printing workshop causes the film static electricity and cause printing difficulties. Too humid the environment can make the ink dry and insufficient, affect the firmness of the ink layer. Therefore, the environmental temperature and relative humidity in the printing workshop should be strictly controlled, and it should be kept as constant as possible, and good ventilation is guaranteed to reduce the printing technology of printing failure. Generally speaking, the temperature in the workshop is suitable for between 18 ° C and 25 ° C, and the relative humidity should be kept between 60%and 70%.
