Measurement Systems for Flexible Packaging

Coating is the process of applying a thin film of functional material to a substrate on a roll, such as paper, fabric, film, foil, or sheet stock. The purpose of applying the coating may be decorative, functional, or both. Coated materials are essential in various industries, including printing and packaging.

Nordson offers a comprehensive portfolio of solutions for coating lines. For applications involving paper substrates, the Series 9 gauge can help companies control moisture levels and measure coat weight with a high level of accuracy. For heavier and thicker substrates, Nordson Beta systems are the winning choice. Lastly, the SR710S infrared sensor is the best solution when it comes to lacquer-on-foil processes.

Extrusion coating involves applying a molten synthetic resin onto a substrate material. This technique is commonly used to apply plastics like polyethylene onto materials such as paperboard, corrugated fiberboard, paper, aluminum foils, cellulose, non-wovens, or plastic films.

Nordson offers various measurement solutions for extrusion coating lines to meet different needs. For instance, a scanning system equipped with the Infrared Series 9 gauge can help measure the basis weight of the extruded layer. Additionally, BETA sensors enable the control of the total basis weight of the web.

For applications requiring high precision, Nordson provides two BETA-sensor systems to be installed before and after the extrusion process for the differential measurement of the two layers using the Same Spot software.

The lamination process involves joining two or more materials to combine their properties and create a substrate with specific characteristics. This process is crucial in the world of flexible packaging, especially for food and pharmaceutical packaging, as it allows for the inner and outer layers of the packaging to have different characteristics. The inner layer is designed for specific functions such as contact, protection, and preservation, while the outer layer focuses on durability, customization, and communication. Special adhesive substances are used to laminate the materials together, and these adhesives are applied in different ways depending on the properties of the individual materials. 

Nordson offers various solutions customized for different applications. Our CW 9000 gauge can help you measure the coat weight and mixing ratio with PU-based adhesives and barrier coatings. In addition, our BETA and XRAY systems enable you to detect the total basis weight of your laminated product. Regardless of your application, our measurement systems will help you avoid delamination, saving time and money.
