Iron eyelets are small, durable metal rings commonly used in the construction of paper carry bags and shoes. In paper shopping bags, iron eyelets are typically placed along the edges of the bag’s handle holes. This reinforcement prevents the handle holes from tearing, ensuring that the bag can securely hold its contents without risk of structural failure. Similarly, in shoes, iron eyelets are often utilized in areas where laces are threaded through . By reinforcing these high-stress areas, the eyelets help distribute tension evenly across the shoe, reducing the likelihood of the eyelets pulling out or the material tearing. They come in various sizes and finishes to accommodate different design preferences and application requirements, offering versatility and functionality across a range of products.
