The ham sausage can be said to be a very versatile food in life, because it can be eaten directly or added to the fried rice to add flavor, and placed in the instant noodles to make the instant noodles look taller and can be made. It’s also great to pair dishes with vegetables such as peppers or cucumbers, even in snacks cooked in various ways on the street! So do you know why the two ends of the ham sausage are sealed with aluminum clips? Here's the Clip Manufacture Equipment Wholesaler to tell you the answer.
An aluminum oxide protective film is formed on the surface of aluminum products, which is used to separate food and usually does not release harmful substances. However, it is not suitable for the long-term storage of acidic and alkaline foods and wines (the inner layer of aluminum canned drinks is covered with a film), do not use a steel ball to clean! At the same time, it prevents air leakage from reacting with the air, causing odor changes and other phenomena.
Aluminum Clip
Taken together, the advantages of using Aluminum Clip closures are:
First, the ham sausage should have the shape of a bowel, not a flat package. The packaging has some heat shrinkage and looks more beautiful, so there are not many sealing options. Secondly, aluminum itself is not a rare metal, and the domestic annual output is close to 40 million tons. Finally, although you think it is wasted on aluminum, the packaging of ham sausage is called Sausage Casing. The material is compounded from PVDC. This should be the best preservation technology currently in existence. PVDC has been used to replace polyethylene as a cling film abroad.
At present, the domestic level is still at the PE level. He kept information in this regard. The aluminum surface is oxidized in the air to form a relatively stable and dense oxide film. Also, it is relatively light. Aluminum is an easily recyclable metal with a higher recovery rate than steel. It can achieve good circulation and prevent waste. If you switch to plastic products, the first is insufficient strength, and the second is non-recyclable (meaningless) and difficult to degrade, which will cause more serious pollution.
Aluminum has a compact structure, light texture and beautiful color, so it is often used as a packaging material, especially for substances with a long fragrance emission period. Therefore, we often see that most of the flavored substances are packaged with aluminum foil outside, mainly because the aluminum foil has a compact structure and the fragrance will not evaporate in a short time. However, when used as food packaging, the direct contact surface with food does not easily becomes aluminum foil because it causes passivation.
