The function of eyelets used on packaging is to provide a reinforced and durable hole for attaching additional items or accessories to the packaging. Eyelets are small metal or plastic rings that are inserted into a hole in the packaging material, such as paper or fabric.

They can be used to attach handles, straps, or other types of fasteners to the packaging, providing a convenient and secure way to carry or transport the product. Eyelets can also be used to reinforce the holes in the packaging, preventing tearing or damage from repeated use. Additionally, eyelets can be customized to match the branding or design of the packaging, adding an extra element of personalization. Eyelets can be a versatile and effective tool for enhancing the functionality and durability of packaging.
