Ready-to-eat is the kind that can be eaten directly after the bag is opened, that is to say, it is processed and cooked, and no processing is needed. If you can't finish eating, you can seal it directly or change it into a self-sealing bag for storage. Ready-to-eat is also a warm reminder to remind customers that you can directly open the bag to eat. It's best to eat it all at once, because you don't have to worry about saving anything.

Open-bag fast food means eating directly. Instant bread is processed bread, which is bought and eaten directly. There are many kinds of bread, so you can choose all kinds of bread to eat. The shelf life of fresh bread made by ordinary bakeries is only three days. The toast was put on the bread counter, and the customers clamped it with clips. Now it is packed in plastic bags. This kind of instant bread is delicious. Supermarket stores sell bread made of long bread, which is vacuum-packed and has a shelf life of up to six months. It doesn't taste good. It tastes terrible.
