E+Series PP/PE Coated Paperboard Paper

Industry knowledge

Justeco's production equipment and clean room environment, how does the production process of E+Series PP/PE coated paperboard ensure the quality of each batch of products is stable and meets customer requirements?

1. Guarantee of advanced production equipment
Justeco's production workshop is equipped with more than 200 precision production equipment, which covers the whole process from raw material processing to finished product production. The production of PP/PE coated paperboard mainly includes base paper coating, coating, die-cutting, printing and other processes.

Coating machine
During the production process, the coating machine is the key equipment to ensure the uniformity and quality of PP/PE coating. Justeco's coating machine adopts advanced coating technology, which can accurately control the thickness, uniformity and adhesion of the coating. The high-precision coating equipment ensures the uniform distribution of the coating on the surface of the paperboard, thereby ensuring the use performance of the paperboard, such as water resistance, oil resistance and durability. The automated control system of the coating process can monitor the coating quality in real time to ensure that each paperboard meets the standards.

Flexographic printing equipment
Justeco's flexographic printing equipment is used to produce E+Series PP/PE coated paperboard with personalized patterns and text. These equipments use high-precision printing technology to ensure that the printed patterns are bright in color, high in clarity, and have good adhesion on the coated paperboard. Through the flexographic printing process, customers can customize different designs to meet the needs of different fields such as food packaging and daily product packaging.

Die-cutting and forming equipment
Die-cutting equipment is used to cut the coated paperboard into the required shape and perform forming operations. Justeco's die-cutting equipment uses precision CNC technology to ensure the accuracy of cutting and the perfect docking of the product. These equipments can flexibly respond to customer-customized size and shape requirements to ensure that the finished products meet the customer's precise requirements. Especially in food packaging, die-cutting technology can ensure that the edges of the paperboard are neat and the shape is perfect, further improving the quality and appearance of the product.

2. Quality control of clean room environment
Justeco is equipped with 100,000-level and 300,000-level clean rooms in its production base to ensure production in a high-standard environment. The control of the clean room environment is another important guarantee for the stable quality of E+Series PP/PE coated paperboard.

The impact of clean room on coating quality
When producing coated paperboard, the coating process has extremely strict requirements on the environment. The cleanroom's efficient air filtration system and constant temperature and humidity control can effectively reduce dust and tiny impurities in the air. This is crucial for the coating process, as pollutants in the air may affect the uniformity, adhesion and final quality of the coating. Justeco's cleanroom can ensure cleanliness during the coating process, thereby avoiding interference from the external environment with the coating quality.

The role of temperature and humidity control
During the production process, the impact of temperature and humidity on coating quality cannot be ignored. Justeco's cleanroom has a strict temperature and humidity control system to ensure that the production environment is always in the best condition. Changes in temperature and humidity may cause uneven drying of the coating or decreased adhesion of the coating. Through stable environmental conditions, Justeco ensures that each batch of cardboard products can achieve the expected results during the coating process and avoid quality fluctuations.

Pollution source control
In the cleanroom, all production personnel need to wear special protective clothing and undergo strict disinfection and cleaning before entering the production area. This not only effectively reduces the pollution sources of the external environment, but also avoids any unnecessary pollutants from entering the cardboard surface during the production process, thereby ensuring the hygiene and safety of the final product. Especially in the field of food packaging, the clean room environment ensures the food safety requirements of the products and complies with international food safety standards such as ISO22000 and LFGB.

3. Quality monitoring and testing
Justeco has a strict quality control mechanism in every link of production to ensure that each batch of E+Series PP/PE coated paperboard meets high quality standards.

Strict inspection of raw materials
The production of E+Series PP/PE coated paperboard starts with the purchase of high-quality base paper. Justeco strictly screens the raw materials and conducts quality inspections before entering production to ensure that the materials used, such as paper, coatings and glue, meet international environmental standards and safety requirements for food contact materials. The quality of raw materials directly affects the quality of the final product. Therefore, Justeco always insists on using environmentally friendly materials that meet international standards.

Real-time quality monitoring during the process
In the production links such as coating, printing, and die-cutting, Justeco uses high-precision monitoring equipment to conduct real-time quality monitoring to ensure the quality stability of the products. For example, through the automated detection system, key indicators such as coating thickness, printing color difference, and flatness of paperboard can be monitored in real time, and automatic adjustments can be made to avoid human operation errors. All deviations in the production process will be discovered and corrected in the shortest possible time to ensure that each batch of products meets quality standards.

Final inspection and testing of finished products
After production, all E+Series PP/PE coated paperboards will undergo strict quality inspections to ensure that the products meet customer requirements. The inspection content includes the thickness of the paperboard, coating uniformity, water resistance, oil resistance, burst resistance, etc. Justeco also conducts strict inspections on the appearance of the products to ensure that the printed patterns have no color difference, high die-cutting accuracy, and meet the relevant requirements of the packaging industry. In addition, the finished products will also undergo environmental testing to ensure that they meet environmental certification requirements such as ISO14001.
