A standing pouch, also known as a stand-up pouch, is a type of flexible packaging bag with a support structure at the bottom, allowing it to stand upright on a flat surface without the need for an external container. It is typically made from multiple layers of high-performance flexible composite materials. Core technologies such as gravure printing and digital printing enable high-quality image reproduction, meeting brands' high demands for visual appeal. Modern standing pouches often feature innovative sealing systems, such as resealable zippers, providing users with a convenient and reusable opening and closing experience. Furthermore, through internal aluminum plating or the use of high-barrier layers such as VMPET, it provides a high level of protection for the contents. Due to its excellent shelf display effect, superior protective performance, and flexible design customization capabilities, the standing pouch is widely used in various industries, including food and daily necessities, under OEM and ODM models, becoming a crucial solution in modern retail packaging.

1. Excellent Barrier Protection

Utilizing a multi-layer composite material structure, such as PET/NY/PE, the nylon layer provides excellent puncture resistance, while the polyethylene layer ensures superior heat sealing. The addition of an internal aluminum or VMPET layer results in a water vapor transmission rate of less than 1.0 g/m²·24h and an oxygen transmission rate of less than 3.0 cm³/m²·24h·atm, effectively blocking air and moisture and ensuring the long-term stability of the contents.

2. Convenient and Reusable Sealing

Integrated self-sealing zipper system. The zipper is made of flexible PE and has undergone rigorous sealing strength testing. Its closing and opening forces are engineered for optimal balance between child safety and adult ease of use, typically controlled between 15-35 Newtons, and can withstand over 200 repeated openings and closings without failure.

3. Stable Upright Display

The unique flat-bottom design, combined with the rigidity of the bag material, allows the packaging bag to stand stably after filling. The bottom support structure can withstand the weight of the contents without collapsing, ensuring optimal display on shelves and enhancing product visibility and brand image.

4. High Physical Performance

The composite material gives the bag high tensile strength and burst resistance. For example, the PET outer layer provides high tensile strength, with a longitudinal tensile strength exceeding 200 MPa; the heat seal strength of the composite structure's sealing edge is typically higher than 40 N/15mm, ensuring that it is not easily damaged or leaked during transportation and stacking.

5. Exquisite Printing Adaptability

Compatible with both gravure and digital printing methods. Gravure printing is suitable for large-scale production, accurately reproducing complex images with a printing precision of up to 175-200 lines; digital printing supports small-batch customization, enabling contactless and rapid plate changes, with a wide color range, meeting market demands for personalization and quick time-to-market.

1. Snack Food Packaging

Widely used for dry or puffed foods such as potato chips, nuts, and jerky. Its high barrier properties prevent the product from becoming damp and soft, and oxygen barrier properties slow down oil oxidation, maintaining a crispy texture. The resealable zipper design allows consumers to use the product in portions, extending the shelf life, and the large packaging display area effectively stimulates purchasing desire.

2. Powdered Beverage Packaging

Suitable for products such as coffee powder, milk powder, and protein powder. The excellent moisture-proof performance of the packaging is crucial, controlling changes in the moisture content of the contents to a very low range. The upright design facilitates pouring, and the flat bottom ensures that the powder inside the bag is completely used, reducing waste.

3. Daily Chemical Products

Used for laundry detergent refills, hand sanitizer, skincare products, etc. The multi-layer composite structure effectively blocks oxygen and light, preventing the degradation of certain active ingredients. The resealable closure keeps the contents clean, and the leak-proof design ensures safe storage. Lightweight packaging significantly reduces logistics costs and storage space compared to rigid bottles.

4. Pet Food Packaging

Suitable for dry pet food and treats. The packaging needs to have high puncture resistance to prevent damage from pets' teeth and claws, while strong barrier properties maintain food flavor and nutrition. The large-capacity stand-up pouch is convenient for storage and use, and the zipper closure is a key function for maintaining the freshness of pet food.
