machine-packed;

Some cities have such specialized companies, which provide these tableware for restaurants;

So, the restaurant doesn't need to buy tableware, all of which belongs to others. He just needs to rent it, and the tableware company will recycle it and repackage it every day.,,,,

In fact, this thing looks sanitary, but it is actually even more unsanitary and not environmentally friendly. There are many disadvantages in the packaging process, and it is banned in many cities.
