The difference between the upper paper and lower paper of pillow packaging lies in their respective positions within the packaging process. The upper paper refers to the material that wraps around the top of the product, while the lower paper is the material that wraps around the bottom.
The upper paper is typically more decorative and eye-catching, as it is the first thing the consumer sees when they look at the product. It often contains branding, product information, and attractive design elements to enhance the product's appearance and appeal.
On the other hand, the lower paper is usually more functional and protective in nature. It serves to secure the product in place, provide padding, and ensure that the product remains intact during shipping and handling.

In terms of application, the upper paper is more commonly used in retail packaging where visual appeal is paramount. It is often seen in products like cosmetics, food items, and gifts. The lower paper, on the other hand, is more prevalent in industrial and shipping packaging where protection and stability are key considerations.

Overall, both the upper and lower papers serve important roles in pillow packaging, with each playing a different but essential part in ensuring the product's presentation and protection.
