Raw Material Cost Volatility: Silgan is highly dependent on a few key raw materials such as steel, aluminum, and plastic resins, whose prices are subject to significant fluctuation, potentially impacting production costs and profitability.

Intense Competitive Environment: The packaging industry is highly competitive, leading to pricing pressures, the need for continuous innovation, and the risk of losing market share to competitors with lower costs or more advanced products.

Customer Demand Fluctuations: Silgan's sales are tied to the performance of its customers in the consumer goods markets (food, beverage, personal care), making it vulnerable to shifts in consumer spending, economic downturns, or changes in customer purchasing patterns.
