What is the difference between unintentional roll paper and intentional roll paper?

What you want to ask is what is the difference between coreless roll paper and cored roll paper? The difference between coreless roll paper and cored roll paper is as follows:

1, used in different places. Household paper is generally cored paper, and coreless paper is mostly used in public places such as hotels and restaurants, that is to say, cored paper is mostly household paper, and coreless paper is mostly business paper. The consumer groups targeted by the two kinds of paper are obviously different.

2, the net weight is different. There is a big difference in gram weight between the two. Coreless roll paper is about 70g, and cored roll paper is about 150g. This shows that for the same roll of paper, the volume of the core roll paper is larger and it takes longer. But if the price is really shared in grams, the price is almost the same.
