Silgan makes the metal cans, plastic bottles, and caps that other companies use to package their food, drinks, and household products.
Silgan is a packaging company. If you buy a can of soup, a bottle of ketchup, or a jug of laundry detergent, there's a decent chance the container came from Silgan. The company doesn't make the stuff inside. It makes the thing that holds the stuff. Its customers are big consumer goods companies — food brands, beverage makers, and household product giants — who need millions of containers that won't leak, break, or react with what's inside. Silgan sells these containers by the billions, and it makes money on thin margins multiplied by enormous volume. Think of it as the plumbing behind the grocery store shelf: you never see it, but nothing gets to you without it.
The business splits into three main parts. The largest is metal containers, which is roughly half of revenue and includes things like steel and aluminum cans for soup, vegetables, pet food, and aerosols. Then there's the closures business, which makes the caps and lids on bottles — the flip-top on a shampoo bottle, the twist-off on a juice jug. And then there's plastic containers, used for things like detergent bottles and personal care products. Each segment sells mostly to large, steady customers on long-term contracts, which makes revenue fairly predictable. In 2024, the company brought in about $6 billion in revenue. That's not explosive growth; it's a grind-it-out business where efficiency, scale, and customer relationships matter more than flash.
Silgan started in 1987 and grew largely by buying other packaging companies. That's still its playbook. It has made dozens of acquisitions over the decades, each one adding new customers or new types of containers. More recently, it has been pushing into higher-value areas like dispensers and specialty closures, where margins are better than commodity cans. The company also returns cash to shareholders through dividends and buybacks, and it has been steadily paying down debt from past deals. The big risks are boring but real: rising raw material costs for steel, aluminum, and resin, plus the fact that its customers have enormous bargaining power. If a giant food company decides to switch suppliers, Silgan feels it. But switching is a hassle, and Silgan's scale and reliability keep most customers around for a long time.
