With new innovative packaging solutions more and more food manufacturers are switching to the stand up pouch with spouts due to special spout designs that  are easy to open and pour yet prevents the products from spilling out.  These packages are highly visible due to the high definition printing capabilities . You can also lower your packaging costs as these packages uses up to 33 times less materials when compared to rigid or glass containers. Customers will save anywhere up to 40% off their packaging costs.

There is a data shows that the revenue market share for liquid packaging sold in spouted pouches has increased to 24.6%. Spouted pouches drove a 30.7% price premium compared to all other packaging formats. And the market share for liquid packaging sold in glass jars and other forms of packaging has decreased more than 20%.

As the application market grows larger, there are more and more requirements for liquid packaging. At present, relying on labor to control the quality of various aspects of liquid packaging production can not meet the requirements. Some common liquid packaging quality problems are as follows, poor printing, poor indentation, poor perforation, and material damage. Lanker’s liquid packaging production process and product quality requirements, combined with Lankaer’s years of experience in flexible packaging, we have a corresponding solution in the quality of liquid packaging production process and factory quality control.

Printing links

Lanker uses front color camera position detection printing on the printing press, and uses the back black and white camera to detect quality problems such as poor punching and indentation after punching and indentation. If the detection system finds a problem, it will promptly report the alarm and display the defect position. The operator adjusts the machine according to the displayed defect position to reduce the generation of continuous printing waste.


Lanker has a detection system for laminating composite aluminum foil raw materials for the production process of the laminating process, mainly to detect the damage of the aluminum foil material. After the detection system finds the problem, it promptly alarms and displays the defect. The operator adjusts the machine according to the displayed defect position to reduce the generation of continuous waste during the lamination process.

Cutting section

Lanker integrates and classifies each defect data detected in the printing process and the lamination process, corresponding to each small plate of each product. For small discs without defects, they can be sent to the finished product packaging through slitting; for defective small trays, pick out the rewinding inspection link. This not only ensures the product quality of the product, but also avoids the reuse of the rewinding link, which greatly improves the production efficiency and reduces the production cost of the enterprise.


Quality control of the rewinding section For the products with quality problems in the slitting process, the front and back inspection systems are used in the rewinding process to test the overall quality of the products. The detection system automatically alarms after the defect is found. The operator can select the defect on the detection system. The detection system will control the rewinding machine to automatically rewind the defect and stop the defect to the manual operation table. After the defect is manually processed, the detection is continued.

Lanker factory is accredited to several widely accepted standards including BRC, ISO22000, GMP, HACCP and has also achieved U.S. Food and Drug Administration.
