Stickers, also called pressure-sensitive labels, are an easy and inexpensive way to label your product or market your brand. They provide an easy way to add your company logo, a UPC barcode and product information to your packaging. With a little creative thinking, a sticker can be useful in promoting your brand or highlighting a company event such as a product's anniversary. Stickers, such as "rush" labels or customized shipping labels, can be useful in enhancing your business operations.
