FOOD PACKAGING INSPECTION
Automatic detection and rejection of sealing imperfections, seal contamination, food packaging integrity, and package content conformity
An efficient food packaging inspection method is necessary for automatically identifying packaging problems or irregularities. For example, faulty packaging may be caused by a number of factors, including sealing defects due to the product, damage to the plastic cup, reels getting out of alignment, faulty materials, failure in processes, etc.
The problem is that such defects often are discovered only upon final handling. This leads to significant waste, loss of revenue, at best. At worst, the products reach the retailer shop, and ultimately the end user. This leads to callbacks, to potential accidents, and complaints that must be handled.
THE VALUE OF LOW-ENERGY X-RAY TECHNOLOGY:
The usage of X-rays with a very low energy (15-20 kV) in on-line applications facilitates imaging of very small composition, density and/or thickness differences.
This is the fundamental basis for making it possible to inspect and detect in real-time seal imperfections and leakers in e.g. plastic pouches, plastic cans with plastic or aluminum foil, and many other packaging types. Deviations in the seal thickness down to fractions of a micron can thus be detected and the object rejected, at production speed up to 180 units per minute.
OUR UNIQUE HYMCIS SYSTEM FACILITATES ONLINE, AUTOMATIC AND REAL-TIME ASSESMENT
- if the aluminum jar/can/pouch is undamaged
- if the plastic/aluminum foil is correctly placed within the acceptance seal zone
- if the seal zone conforms to the defined area for the welding
- if the plastic/aluminum foil is free of folds and other similar defects
- if there is no product lying in the seal zone
- if there is product lying outside the seal zone
- if there is no contamination of the product
- if the right amount of product is filled into the plastic/aluminum jar/can or pouch
- if the distribution of the product within the jar/can/pouch is homogeneous
- if the density of the product corresponds to acceptance criteria
- if the homogeneity of the product meets the acceptance criteria
