Simple, hygienic and recyclable in fast modern life, it is indispensable for take-out, air, and home bakeries. When you hold a light, slender container of aluminum foil in your hand, not many people will think that behind that tiny container are condensed the complex decisions of materials science and precision machining. Today we decipher in depth 8011-H22 Aluminum Foil double-sided transparent coating gourd, the key material for making high-end aluminum gourd, to explore the cipher of the technology behind the name.
Not all aluminum can make lunch boxes. The dining box must withstand huge tensile and deformation through the frame. The material must have sufficient strength to maintain its form. You need a good stretch that doesn't work. 8011 aluminum alloy is an Al-Fe-Si type alloy, currently the 'flagship' of the aluminum thin alloy industry.
Among these, the status of H22 is the key to unlock the performance of the material. This means that the aluminum foil was lightly cold-hardened and then degenerated heat treated to make it finally 1/4 firm. In short, this process causes you to have "muscle" just right for the aluminum gourd. The usual tensile strength is 125~165. Not only does it not break well in press molding among mpa, but also ensures that the finished box is in hand and not straight and soft enough. This machinability creates a solid foundation for subsequent high - elevation machining.
Traditional pure aluminum gourds are easy to oxidize on the surface, so there is a limit in internal corrosion. Through a special process, a transparent protective layer was painted on both sides, restoring its resilience.
Corrosive REINFORCEMENT: THE COATING EFFECTIVELY BLOCKS MOISTURE AND AIR AND PREVENTS ALUMINUM FOIL FROM REACTING WHEN IN CONTACT WITH ACIDIC FOODS (LEMON JUICE, TOMATO SAUCE, ETC.).
Thermal sticker performance improvements: For containers that require a seal membrane, the transparent coating often has a special treatment, and it is tight with the top seal membrane to prevent the soup from leaking.
Beauty and Logo: Its transparent properties don't hide the metallic sheen of the aluminum foil itself, but provide a uniform surface.
You need the 'hero on the back' to turn it into a lunch box if you have good filling and coating. Lubricants. The production process of aluminum foil container divides greatly, detect 6 steps: precharge, drawing, delivery, press molding, drop charge. Lubricants play an important role in this process.
Under pressure of 40 tons to 80 tons, a large amount of heat is generated by high-speed friction of the mold and aluminum foil. At this time, the lubricants on the surface of the aluminum foil should quickly release heat to protect the mold and the aluminum foil surface from injury. More importantly this lubricant should be for food use.
According to the international standards of NSF (National Health Foundation of the United States of America), lubricants in contact with food are at h1 or 3h level, colorless, tasteless, and it is guaranteed that there is no impact on the texture or safety even if there is trace amount left. The control of the amount of painting oil in the production of 8011-H22 aluminum foil is a precise academic -- paint too little, the lack of lubrication may cause, but the pack crack damage; If you paint too much, the container sticks to the mold and affects productivity. The amount to be applied is usually between 30mg and 1g, which should be adjusted accurately.
The 'double-sided coating + lubricants' design in 8011-H22 aluminium foil, its greatest advantage is a unified solution. The transparent coating solves the functional problem when using lunch box. (corrosion-resistant, hot-bondable), surface food grade lubricants solve the problems in the processing. (simple molding, protective) this aluminum gourd is the aluminum processing plant lubrication process is complete. After the packaging material arrives at the restaurant factory, it can be pressed directly. Bypassing the cumbersome process of the guest oiling themselves. Ensure the uniformity and cleanliness of lubrication.
Aluminum ALLOY, strong coating aluminum gourd, such as thin ohgandhi wings, full of delicious lunch box in our hands, 8011-H22 double-sided coating aluminum gourd all changes can not do without precise carving of technical skills. It embodies the ultimate pursuit of the performance of materials as well as the aluminum processing industry and attaches importance to the safety and high efficiency of modern food industry and perfect interpretation of ideology. As the world is increasingly in the demand of green packaging, these home high strength, high order single-component, reverse processing and green suiting materials necessarily play a more important role in the wave of green packaging.
