Thinking about the safety of the product, in a strict sense, it should be tested after the product is packaged, that is, it is tested behind the packaging machine. However, at present, the metal detection in the food operation industry has a relatively headache problem, which is the problem of aluminum packaging. Metal detectors are divided into all-metal detectors and magnetic metal detectors. At present, the aluminum film is relatively thin, or products with aluminum-coated film, our Keyang all-metal detector can handle. Magnetic metal detectors can only detect ferrous metals Yes, stainless steel, aluminum, and copper are not detectable. So there are four ways for your reference: 1. Choose a full metal detector, the price: 20,000 to 30,000 2. Choose a magnetic metal detector, the price: 10,000 to 10,000 3. Choose X-ray foreign body detector. Price: 60,000-400,000. 4. Professional aluminum metal detector imported from Japan 25-200,000.
