Aluminum foil is impervious to moisture, light, bacteria and all gases. Because of it's ability to block out bacteria and moisture especially, it helps the food last longer than if it were wrapped in plastic. So it becomes more and more popular in food packaging industry. However, aluminum foil package is a "headache" for Metal Detector manufacturers, since traditional metal detector couldn't pick up metal contaminants in foil package, while the aluminum foil metal detector has "worse" sensitivity for stainless steel304/316. So here is our solution: Low energy cheap X-ray Inspection System.
It features at low owner-ship, much better sensitivity than metal detector(0.5mm), capable of picking up glass/ceramic/stone/hard rubber, etc contaminants.
