The paper companies utilize every bit of paper, recycle it and produce products from it to ensure zero wastage and environmental damage. Once something gets worn out or used, the cycle repeats.
Manufacturing companies are producers of a product. Similarly, packaging companies produce industrial paper products. These products have several different purposes. For example, apart from wrapping, some products get used to making thicker boards like cardboards; some used ones get reduced to pulp and then transformed into items including benches, shelves, blackboards, etc.
