You have to know the quality parameters that need to be paid attention to when buying aluminum foil
In the production process of aluminum foil, it has to go through multiple processes such as rolling, finishing, annealing, packaging, etc., and the production process is interlocking. Any problem in any link may lead to quality problems of aluminum foil. The quality defects of the purchased aluminum foil products will not only affect the appearance, but also directly affect the quality of the produced products, and what's more, it will directly cause the aluminum foil to break and stop, which will greatly affect the production efficiency. So how to distinguish the quality of aluminum foil?
According to the experience of people in the aluminum industry, you can directly use your "eyes" to detect the quality of aluminum foil. However, to distinguish the quality of aluminum foil, we should first understand what are the common quality defects of aluminum foil.
Today, I will sort out the most comprehensive aluminum foil quality defect problems in history for you, and attach a high-definition large picture of the problematic aluminum foil. When we buy the aluminum foil back, we only need to diagnose the problem once for this batch of aluminum foil. Whether the quality is good or bad is natural. You can get it out!
1. Aluminum foil bumps
▲ Aluminum foil bruising refers to the damage on the surface or end surface of the foil material after it collides with other objects during handling or storage. Most of the bruises are caused by carelessness in aluminum foil packaging.
2. Corrosion
▲ The surface of the aluminum foil is in contact with the surrounding medium, and after a chemical reaction or electrochemical reaction occurs, defects will be generated on the surface of the aluminum foil, the surface of the corroded aluminum foil will lose its luster, and gray corrosion products will be produced in severe cases. The corroded aluminum foil will have a great impact on the aesthetics of the products produced by the terminal.
3. Surface air bubbles
▲ Aluminum foil with surface bubble defects will have irregular circular or strip-shaped cavity bulges on the surface of the foil; the edges of the bulges are smooth, the two sides are asymmetrical, and the distribution is irregular. If the force is unbalanced, it is likely to cause the breakage and shutdown.
4. Dark Side Streaks
▲ Most of the stripes on the dark side appear on double-heeled products, and the dark side has obvious light and dark stripes along the rolling direction, which affects the ap

| Why Aluminum Foil Was Formerly Called Tin Foil？ |

Aluminum foil was originally called "tin foil" because it was made using a process that was similar to the production of tin foil. Tin foil was first introduced in the 19th century and was made from thin sheets of tin that were hammered into a very thin and flexible form. Tin foil was popular for its ability to keep food fresh and to protect it from insects and bacteria.
In the early 20th century, aluminum foil was developed as a replacement for tin foil. Aluminum foil was cheaper and easier to produce than tin foil, and it was also more effective at protecting food from moisture, bacteria, and other contaminants. However, because aluminum foil was so similar in appearance and function to tin foil, people continued to refer to it as "tin foil" for many years.
Today, the term "tin foil" is still sometimes used colloquially to refer to aluminum foil, although it is less common than it once was. The more accurate term for the material is simply "aluminum foil."

Oiled and unoiled container foil refers to two different types of aluminum foil used to package food or other products.
In the production process, in order to prevent the aluminum foil from sticking to the rollers on the machine at high temperature, all aluminum foils for containers need oil during production. Some machines have their own oil spray settings and you can buy container foils that are not oiled, but there is no oil on the machine. For oiled settings, oiled container foil must be purchased.
Usually oiled container foil is about 100-150 US dollars per ton more expensive than non-oiled container foil.
The oil also helps prevent air and moisture from penetrating the foil, which preserves the freshness and flavor of your food.
It is worth noting that the type of oil used to oil container foil may vary by manufacturer or supplier. However, mineral oil is the commonly used oil for this purpose due to its low cost, availability and non-toxicity. Other types of oils that can be used include vegetable oils such as soybean or canola and healthy olive oil.
