Liquid flexible packaging film printing process attention problems – Packaging,
Select appropriate materials. In actual production, should be based on the filling speed automatic filling machine, sterilization conditions, the length of product shelf-life situation such as to select the appropriate Print Film and printing inks, and adjusted according to actual situation and control the printing process parameters, standardized process to ensure the film's print quality. Polyamide surface printing inks because of its water resistance, good resistance to grease, liquid packages generally can not use ink; polyurethane inks have different types to choose when to have targeted the new super power Fuk 313A Oriental ink generally used only for soft co-extruded PE film, and 314 type is suitable for all kinds of co-extruded PE film. Used in color printing factory co-extruded PE film blowing is usually made on their own, different skills, so be sure to grasp the parent material selection, it is appropriate agent models of female non-slippery material; use of PE film after electric discharge treatment, surface energy minimum to 40 dyne, preferably more than 42 dyne.
Customers or testing standards after the processing conditions. Only by fully understanding of color printing factory Food Manufacturers in terms of time of filling and the subsequent processing of the process, even the liquid bag in the market circulation of details of the requirements to be targeted an idea. The attention of the major points include: filling speed, sterilization conditions, the length of shelf life, preservation requirements.
Printing process requirements. To ensure the liquid Package Film printing quality, in the printing process must also pay attention to tension on the printing, print pressure, print speed and drying temperature control of process conditions, to develop a stable and reliable technology standards, specifications process, to ensure the smooth progress of the scale of production. In addition, the overall quality printers, ink manufacturers provide technical information, good or bad dilute the quality of materials, workshop environment, changes in factors that can not be ignored.
Good control printing environment. Pressroom changes in temperature and humidity inside the substrate material and ink are some of the performance, the environment is too dry will cause static film, resulting in printing problems; environment is too dry and wet ink will not fully affect the strong degree of ink. Therefore, we should strictly control the temperature within the printing shop and relative humidity, as much as possible so that it remains relatively constant, and ensure good ventilation to reduce the incidence of printing faults. In general, the workshop of the temperature control in between 18 ~ 25 is appropriate, the relative humidity maintained at 60% ~ 70% is appropriate.
Good product inspection. Customer satisfaction is high for each criterion, a printing business and the ultimate desire, it will be qualified to ensure the finished product sent to the customer. This would allow customers to achieve satisfaction, but also to maintain the image and reputation of the company, which is to maintain and develop good customer relations.
Liquid package production process, more frequent exchange membrane, easily lead to different properties of the films, the liquid bag with a little ink, a long time to use the old ink printing ink may also bring performance degradation, therefore, liquid bag more variable factors of production. Printing business customers through the use of simulated conditions, to develop an appropriate product testing standards to ensure the unqualified products are not manufactured, to avoid unnecessary losses.
