What is the difference between octagonal sealed bags and self-supporting bags?

Both octagonal sealed bags and self-supporting bags are used in the field of food packaging, but they have significant differences in structure, function, and characteristics. The following is a detailed analysis of the differences between the two:
1、 Structural design:
Eight sided sealing bag: The bottom is flat with a total of eight edges, including four edges at the bottom and two edges on each side. This design allows the octagonal bag to have five display surfaces, including front, back, left, right, and bottom, which can better showcase product information and brand.
Self standing bag: It has a folding bottom and two edge seals, one on each side. After the bottom is opened, the self standing bag can stand on its own without relying on any support. The bottom of the self-supporting bag is not completely flat, but has a certain curvature or support structure.
2、 Function and Features:
Eight sided sealed bag: Due to its multiple display surfaces, the eight sided sealed bag can carry more product information content, which is very beneficial for promoting products and brands. At the same time, the eight sided sealed bag structure makes it more stable and has a better sense of three dimensionality. However, the cost of eight sided sealed bags is relatively high, and the technical requirements are also more stringent.
Self standing bag: The self standing function of the self standing bag gives it a better visual effect when displayed on shelves, which can attract consumers' attention. The structure of the self standing bag is relatively simple, the cost is low, and it is widely used in various food packaging. The advantages of self standing bags also include easy portability, convenient use, freshness preservation, and sealability.
3、 Application scenarios:
Eight sided sealed bag: Due to its superior display effect and high technical requirements, eight sided sealed bags are commonly used for packaging high-end food, health products, and other products to highlight the product's grade and value.
Self standing bags: Self standing bags have a wider range of applications, not only for food packaging, but also widely used in packaging of daily necessities, cosmetics and other fields. The self standing function of the self standing bag makes it more effective for display on shelves and suitable for sales in retail channels such as supermarkets and convenience stores.
In summary, there are significant differences in structure, function, and characteristics between octagonal sealed bags and self-supporting bags. The choice of packaging bag mainly depends on the nature of the product, market demand, and cost considerations.
