snack bag
Design type
1. Three-side sealed bags: These bags are sealed on three sides, leaving one side open for product insertion. This is the most common type of food packaging. Three-side sealed bags have two side seams and one top seam; they can be folded or unfolded. When folded, they can be placed upright on shelves. Three-side sealed bags are suitable for a variety of products, including snacks, condiments, face masks, and pet treats.
2. Stand-up pouches: As the name suggests, this type of food packaging pouch can stand upright on shelves, providing a better and more attractive display effect. Stand-up pouches are widely used for snacks, jellies, condiments, and cleaning products. These pouches not only have excellent airtightness but also effectively maintain product freshness.
3. Octagonal-sealed bags: Developed from stand-up pouches, these bags have a square base and can stand upright. Octagonal-sealed bags have a more three-dimensional appearance, with three surfaces (front, sides, and bottom), offering more printing space and product display area than stand-up pouches, thereby better capturing consumers' attention. Octagonal-sealed bags are suitable for packaging coffee beans, tea, nuts, dried fruits, and pet snacks.
4. Stand-up zipper bags: Based on stand-up pouches, these bags feature a reusable zipper seal at the top for convenient storage and consumption, preventing moisture damage. This packaging is widely used in the food industry, particularly for snacks, puffed foods, meat products, and instant coffee. It allows consumers to enjoy the product anytime while extending the shelf life, offering waterproof, moisture-proof, and insect-proof functionality.
5. Back-sealed bags: A type of packaging bag with the back edge sealed. It has no opening and must be torn open by hand. It is commonly used for small packages of powdered products, candies, and dairy products. The back-sealed rolled-edge bag design is ingenious, with the sides cleverly folded inward to create a unique side packaging style. This bag effectively reduces the exposed areas on both sides, saves storage space, and makes the overall appearance more aesthetically pleasing. Additionally, its large capacity is highly praised, making it ideal for packaging baked goods, convenience foods, and frozen foods.
6. Spout pouch: Comprising an independent spout and a stand-up pouch, it is the preferred choice for packaging liquids and powders, such as juice, beverages, milk, and soy milk. This bag is particularly suitable for packaging liquid and powder products. Its design facilitates the transportation and storage of food, and its practicality and convenience are widely praised.
7. Irregular-shaped bag: Breaking away from traditional square designs, it can showcase unique styling based on product characteristics. Irregular-shaped bags are suitable for packaging candies, snacks, instant beverages, and specialty products, adding a unique charm to the product.
