An on-pack sticker is a small adhesive label that is affixed to the packaging of a product, typically containing important information or promotional messaging. These stickers are designed to catch the eye of consumers and provide additional details about the product, such as ingredients, nutritional information, or special offers. They are commonly used by brands to enhance the visual appeal of their packaging and communicate key selling points to potential customers. On-pack stickers are a versatile marketing tool that can be easily added or removed from packaging, making them a cost-effective way to promote products and engage with consumers.
