The container for the chocolate can be not only bags, boxes, but also paper tube packaging. Food grade paper tube packaging has high requirements for safety and airtightness, so that it can effectively isolate the outside air and moisture from affecting the food inside the package. If the paper tube packaging is in direct contact with chocolate, especially chocolate powder, and the chocolate powder is not contained in a sealed bag, the requirements for chocolate tube packaging are very high. In order to improve the sealability of food tube packaging, laminating aluminum foil on the inner wall of the paper tube is the most common method. But for cylindrical packaging that directly contains food powder, it is not enough to laminate aluminum foil on the inside of the paper tube. In order to increase the tightness of the lid, a safe iron lid is usually used at the bottom, and an easy-to-tear foil cover is used on the top of the paper tube.

However, the foil cover is very thin and needs to be protected. Therefore, use a paper cover to protect the foil cover. The foil cover is a disposable product, it cannot be restored after being opened, nor can the food inside be packaged.

Food tube packaging can print any content, which will play a role in promoting products and brands.
