Snack packaging bag

There are many types of designs and material choices for snack packaging bags. The following is a detailed analysis of snack packaging bags:

Design Types

1. Three-side seal bag: Sealed on three sides, leaving one side open for product filling. This is the most common type of food packaging. The three-side seal bag has two side seals and one top seal; it can be folded or unfolded. When folded, it can stand upright on shelves. Three-side seal bags are suitable for various products, including snacks, seasonings, face masks, and pet snacks.

2. Stand-up pouch: As the name suggests, stand-up pouch packaging can stand upright on shelves, better displaying the product and enhancing aesthetics. Stand-up pouches are widely used for packaging snacks, jelly, seasonings, and cleaning products. This type of packaging not only has good airtightness but also effectively maintains product freshness.

3. Eight-side seal bag: Developed based on the stand-up pouch, the bottom of the bag is square, allowing it to stand upright. The eight-side seal bag has a more three-dimensional feel, with three flat surfaces: front, side, and bottom. Compared to stand-up pouches, it offers more printing space and product display area, attracting consumers' attention more effectively. Eight-side seal bags are suitable for packaging coffee beans, tea leaves, nuts, dried fruits, and pet snacks.

4. Stand-up zipper pouch: Based on the stand-up pouch, the bag mouth is equipped with a resealable zipper, convenient for storage and consumption, preventing moisture damage. This packaging is widely used in the food industry, especially suitable for snacks, puffed foods, meat products, and instant coffee. It is easy to use, extends product shelf life, and prevents damage from water, moisture, and insects.

5. Back seal bag: A bag type sealed at the back edge. It has no opening and needs to be torn open. Commonly used for small packages of powder, candy, and dairy products. The back seal bag has a clever side wing design; the two sides fold inward, forming a unique side packaging style. This effectively reduces exposed side areas, saves storage space, and improves aesthetics. Its large capacity is also highly praised, suitable for baked goods, convenience foods, and frozen foods.

6. Spout bag: Composed of an independent dispensing spout and a stand-up pouch, very suitable for packaging liquids and powders such as juice, beverages, milk, and soy milk. This packaging bag is especially suitable for liquid and powder products; its design facilitates transportation and storage, and its practicality and convenience are widely praised.

7. Shaped pouch: Breaking the traditional square design, these bags can showcase unique styles according to the product's characteristics. Shaped pouches are suitable for candy, snacks, instant drinks, and specialty foods, adding unique appeal.
