The Molins Langen range of carton testing instruments (LCT & OCT) is used to measure variations in carton packaging. More specifically; crease quality and frictional forces between carton surfaces as these parameters can directly affect the consistent flow of cartons through form & fill machines.
The Molins Langen LCT measures the torque required to fold the carton crease, as well as the coefficient of friction, which is the degree of slippage between the surfaces of adjacent cartons as these are fed from the magazine of the form & fill machine. The instrument also records the spring back force, which indicates the material’s resilience after the crease is folded; this is important as it can affect the way the carton behaves during the forming process, and can also cause glued flaps to spring open before the adhesive has had time to cure.
The LCT’s “V1.71 CT software” is very versatile and enables users to devise a structured carton performance assessment. Carton data can be recorded and used by end users and converters alike. End users gain from an improved running efficiency on form & fill lines while converters gain from a reduction in rejected cartons.
Two Instruments = Five Measurements
The OCT is an optical instrument that measures the crease dimensions including crease width, bead, angles and symmetry of the flat board as well as the formed box. Data from the LCT and OCT is used to assess if the carton packaging variations are due to material changes or due to mechanical issues.
A systematic use of the LCT and OCT instruments can significantly reduce carton packaging waste and machine downtime. This in turn can result in significant cost savings for both packaging end users and packaging converters.
