Foil Stand Up Pouches are a type of stand-up packaging bag made from aluminum foil layers or composite materials with high barrier properties. These bags are characterized by their self-supporting structure, emphasizing that the bag maintains a certain rigidity even when unfilled, ensuring excellent display properties during shelf presentation and transportation. Foil Stand Up Pouches typically utilize a multi-layered structure formed through composite materials, allowing the bag to achieve ideal sealing capabilities while remaining lightweight. The aluminum foil layer acts as a strong barrier, effectively blocking air, moisture, and a certain degree of light, maintaining the stability of the contents. These products are often used with various printing processes to meet customer needs in brand presentation and are compatible with various bag types and packaging equipment of different capacities. Their manufacturing process relies on mature flexible packaging processing technology, forming a stable bag structure through processes such as slitting, lamination, and bag making, making them suitable for product categories that require packaging integrity and attractive visual presentation.

1. High Barrier Properties

Foil Stand Up Pouches utilize a multi-layer structure such as PET/AL/NY/PE or PET/VMPET/NY/PE. The aluminum foil layer provides excellent barrier properties, with oxygen transmission rates as low as 0.1–0.3 cc/m²·day and water vapor transmission rates of 0.1–0.2 g/m²·day, ensuring that the contents remain dry and stable even during long-term storage. High barrier properties are particularly important in the food and health product industries, reducing the impact of the external environment on the contents and maintaining product flavor and quality. The multi-layer structure, using advanced composite technology, gives Foil Stand Up Pouches excellent puncture resistance and sealing strength.

2. Good Standing Stability

Foil Stand Up Pouches come in various bag types, including SUP, eight-sided seal, and flat-bottom bags.  The combination of bottom folds and the rigidity of the composite film allows the bag to maintain a stable upright display on shelves. Bag rigidity is usually controlled by the thickness combination of the PET and NY layers, typically using a PET 12–20μm and NY 15–25μm structure, ensuring good standing stability even when unfilled. The upright structure improves shelf display efficiency, giving products higher visibility, and is suitable for various retail scenarios.

3. Excellent Sealing Performance

The bags use a heat-sealable PE or RCPP material, with a heat-sealing temperature range of approximately 120–140°C and a sealing strength of 30–40N/15mm, ensuring that Foil Stand Up Pouches maintain seal integrity during transportation. Different material structures offer high-temperature or freeze resistance, suitable for various filling processes, such as hot filling, room temperature filling, and solid particle packaging. High sealing strength reduces the risk of leaks and bag breakage, improving product stability during cross-border transportation.

4. Customization Flexibility

Foil Stand Up Pouches support comprehensive customization, from materials and bag types to printing patterns.  Structures such as PET/PE, OPP/VMPET/PE, and PET/AL/NY/RCPP can be customized according to brand needs, and different visual effects such as glossy, matte, or partial gloss finishes can be achieved. Printing capabilities of 8–10 colors are available, utilizing gravure or digital printing technology for high color fidelity. Bag sizes can be adjusted according to product capacity, compatible with various automatic packaging machines to improve production efficiency.

5. Durable Structure

The multi-layer composite material structure gives the bag high strength, with a puncture resistance value of 8–12N, providing greater safety during transportation and stacking of Foil Stand Up Pouches. The NY layer provides tear resistance, the PET layer ensures a crisp appearance, and the AL or VMPET layer provides a physical barrier. The overall structure is resistant to moisture and deformation, suitable for medium-to-long-term storage of dry, powder, and granular products. Bag thickness is typically 80–150μm, and can be selected according to product requirements.

6. Excellent Brand Presentation

The bag surface allows for large-area printing with a printing accuracy of 150–200 lines, giving Foil Stand Up Pouches a high visual impact in brand presentation. The gloss of the composite material is stable, and combined with the metallized effect or high-opacity structure, it enhances the packaging's visual appeal. Transparent windows, laser coding, and anti-counterfeiting labels can all be incorporated, helping customers enhance product differentiation and increase attractiveness in retail settings.

1. Food Retail Shelves

Foil Stand Up Pouches are suitable for nuts, coffee beans, grains, dried fruits, and other categories. Their barrier structure helps keep food dry. The pouches' upright design enhances display on retail shelves, allowing consumers to quickly identify product information. The ample printing area provides food brands with a better packaging presentation.

2. Beverage Powder Packaging Area

Suitable for powdered products such as milk tea powder and protein powder. The high sealing performance of Foil Stand Up Pouches effectively reduces the risk of powder leakage, and the composite structure remains stable even in high-humidity environments. The stand-up pouch structure is convenient for end-users to access in kitchens, bars, and other locations.

3. Pet Food Display Area

The pouches have high strength, making them suitable for granular pet food. Foil Stand Up Pouches can adjust the material thickness according to the weight of different pet foods, ensuring integrity during transportation and stacking. The large printing area also helps improve product recognition and brand appeal.

4. Health and Nutrition Products Area

Suitable for health products such as gummies, capsules, and meal replacement powders. The high barrier structure helps maintain the stability of the contents, preventing light or oxygen from affecting product activity. Foil Stand Up Pouches can be combined with features such as easy-tear openings and hanging holes to enhance the consumer experience.

5. Coffee Shop and Bakery Packaging Area

Foil Stand Up Pouches are commonly used for packaging coffee powder, baking ingredients, etc. Their light-blocking properties help maintain the freshness of the ingredients. The upright design of the pouches facilitates in-store display, and the printed design can reinforce the visual style, making the packaging look more professional.

6. Agricultural Product Sales Area

Used for agricultural products such as dried chili peppers, beans, grains, and seeds. The composite structure of Foil Stand Up Pouches resists external moisture, maintaining the dryness of agricultural products. The pouch design can include a transparent window according to sales needs, allowing consumers to more intuitively understand product quality.
