What is the largest market for plastics today?

The packaging sector is the largest user of plastics today.

Who is the largest plastic manufacturer in the U.S.?

Dow is the largest manufacturer of plastics in the United States.

Which plastic company share is best?

There is no one perfect stock for all buyers. Investors looking for a business primarily focused on plastics might pick Dow. But investors seeking more diversification would likely prefer ExxonMobil, which has a large plastics business in addition to its oil and gas operations.

How profitable is the plastic industry?

Profitability can vary based on demand, but overall, plastics is not a high-margin sector. Profitability in the sector is affected by factors such as raw material costs, supply chain disruptions, and increasingly stringent environmental regulations, which can raise operating costs.

Are plastic stocks a good long-term investment?

Plastics are in demand from a wide range of industries, providing some predictability. This is not a high-growth sector, but plastics can be a good long-term investment for those seeking a combination of modest growth and income.

Can investing in plastic stocks help hedge against inflation?

Materials companies tend to hold up well during periods of inflation, and plastics are essential to so many industries that demand remains resilient. However, it is important to keep in mind that plastic is made from hydrocarbons. When inflation is driven by an energy crisis, the cost of raw materials for plastic skyrockets.

ExxonMobil (XOM -1.20%) is best known as an oil and gas company, but it is also a major producer of specialized polypropylene, a raw material used in plastics. Propylene is a molecule produced as part of the oil-refining process, making it a natural offshoot of ExxonMobil’s core business.

ExxonMobil significantly boosted polypropylene production in 2020 to meet increased demand for masks and medical supplies to support the COVID-19 pandemic response.

This company is deeply entrenched in the fossil fuel economy, but plastics offer some diversification from the oil giant's core petroleum offerings.
