The paper used in paper cups is biodegradable, and in this article Paper Soup Cup Suppliers joins us to discuss the intricacies of paper cups.
The next time you pick up a cafe latte from your neighbor's barista or Starbucks, look at the cup itself. Chances are, it's a paper cup, which makes paper cup makers optimistic about the future. Some even say that the demand for paper cups will reach 100% in the near future due to the awareness and measures being taken by the government to promote the use of paper cups.
The problem with recyclin
The real question is, are paper cups better?
When comparing the recyclability of Paper Cups and plastic cups, paper cups win by a wide margin. This is because paper is the main component of paper cups, which are naturally biodegradable.
This is an advantage. However, when you look at the manufacturing process of paper cups, it involves a stage called waterproofing, where a layer of LDPE is stacked on the sides and bottom of the cup to prevent water from being absorbed by the paper. This layer of LDPE is the only drawback in paper cups. This is because as a plastic material LDPE prevents the paper from being recycled.
Therefore, paper cups are not recyclable under normal circumstances. It requires a special process to separate the LDPE coating from the paper and the cup scrap is heated in a solution to remove the plastic lining. After that, the waste paper is shredded and recycled, and finally the impurities are filtered out. The final pulp can be used to make other paper products.
