Established customer relationships: Long-term supply agreements with major consumer packaged goods companies deter new players.

Economies of scale: Large-scale production enables cost advantages not easily replicated by new entrants.

Silgan Holdings operates in an industry with high entry barriers, low supplier power, and a manageable threat from substitutes, supporting a strong competitive position.
