International Paper Company makes paper and packaging products, including containerboard used in corrugated boxes, one of the largest paper and packaging companies in the world. Its packaging products are essential to how goods move through supply chains, since virtually every physical product shipped or sold at retail requires some form of packaging, giving International Paper steady underlying demand tied to broader shipping and retail activity. The company operates a vertically integrated business spanning forestry, pulp and paper manufacturing and packaging conversion, capturing margin across multiple stages of the paper and packaging supply chain. International Paper's revenue and profitability are tied to overall industrial production, e-commerce shipping volumes and broader economic activity, since packaging demand tends to track how much product volume is being manufactured and shipped across its many customer industries.
