The Anderson Company in the United States produces a jet-packed butter for the convenience of fast food restaurants. The butter is packaged in a polyethylene tube and can be cut with a knife depending on the amount used. The butter is added to the seasoning. This package will not have butter left in the package, reducing waste and making it easy to eat. Now, this kind of jet-packed tubular butter is put on the market in several sizes, but it can also be increased or decreased according to the requirements of users. At present, many fast food restaurants in the United States are using this kind of packaged butter.
