Snack packaging bag

Snack packaging bags offer a variety of options in design and materials. Below is a detailed analysis of snack packaging bags:

Design Types

1. Three-side seal bag: Sealed on three sides with one side left open for product insertion, this is currently 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, and when folded, it can stand upright on shelves. It is suitable for various products including snacks, seasonings, facial masks, and pet snacks.

2. Stand-up pouch: As the name suggests, this type of food packaging bag can stand upright on shelves, providing a better and more attractive display effect. Stand-up pouches are widely used for snacks, jelly, seasonings, and cleaning products. This type of bag not only has good airtightness but also effectively maintains product freshness.

3. Eight-side seal bag: Developed based on the stand-up pouch, this bag has a square bottom that allows it to stand upright. The eight-side seal bag has a more three-dimensional feel with front, side, and bottom surfaces. Compared to stand-up pouches, it offers larger printing space and better product display, more effectively attracting consumer attention. It is suitable for packaging coffee beans, tea leaves, nuts, dried fruits, and pet snacks.

4. Stand-up zipper pouch: Based on the stand-up pouch, this bag adds a resealable zipper at the top for convenient storage and consumption, preventing moisture damage. This packaging is widely used in the food industry, especially for snacks, puffed foods, meat products, and instant coffee. It not only facilitates consumer use but also extends shelf life, featuring waterproof, moisture-proof, and insect-proof functions.

5. Back seal bag: A packaging bag sealed along the back edge. It has no opening and needs to be torn open by hand. Commonly used for small packages of powder, candy, and dairy products. The back seal corner bag features a unique side cleverly folded inward, creating a distinctive side packaging style. This design reduces the exposed area on the bag's side, saves storage space, and improves overall appearance. Its large capacity is also highly praised, suitable for packaging baked goods, convenience foods, and frozen foods.

6. Spout pouch: Composed of an independent spout and a stand-up pouch, it is an ideal choice for packaging liquids and powders such as juice, beverages, milk, and soy milk. This bag is especially suitable for liquid and powder products; its design facilitates food transportation and storage, making it practical and convenient.

7. Irregular shape bag: Breaking the traditional square design, it can showcase a unique style based on product characteristics. Irregular shape bags are suitable for candy, snacks, instant drinks, and specialty products, adding unique charm to the product.

Material Selection

1. BOPP/CPP double-layer composite material: Oil-resistant, high transparency, good hardness, suitable for biscuits, candy, and light snacks.

2. BOPP/VMCPP double-layer composite material: Oil-resistant, oxygen barrier, light-blocking, good hardness, suitable for potato chips, fried foods, and dry goods.

3. BOPP/LDPE double-layer composite material: Cold-resistant, high low-temperature heat seal strength, suitable for instant noodles, snacks, frozen desserts, and powder packaging.

4. BOPP/VMCPP/LLDPE three-layer composite material: Moisture-proof, oxygen barrier, light-blocking, suitable for rice-based snacks and tea leaves.

5. PET/CPP double-layer composite material: Moisture-proof, aroma-preserving, high temperature resistant, suitable for alcoholic beverages, aromatic foods, and frozen buns.

6. Aluminum metallized film bag: Suitable for packaging products that should not be exposed to moisture and need to stay dry, such as powdered foods or medicines, food additives, and vacuum-packed cooked meats.

When choosing snack packaging bags, besides considering design and materials, the following points should also be noted:

1. Safety: Ensure the packaging bag meets food safety standards and is non-toxic and harmless.

2. Environmental protection: Choose biodegradable or recyclable packaging materials to reduce environmental pollution.

3. Printing quality: The information printed on the packaging bag should be clear, accurate, and comply with relevant regulations.
