Paper-Corrugated (Manufacturing) is a subdivision of the Converted Paper and Paperboard Products, Not Elsewhere Classified (Manufacturing) industry. This industry involves the manufacturing of corrugated paper products, which are commonly used for packaging and shipping purposes. The process of creating corrugated paper involves layering a fluted sheet between two flat sheets of paper, which creates a strong and durable material that can withstand pressure and impact. The corrugated paper is then cut and folded into various shapes and sizes to create boxes, cartons, and other packaging materials.
