Stand Up Barrier Pouches are self-standing flexible packaging bags widely used in the modern packaging industry.  Their core feature is a structurally designed base that allows them to stand upright, making products more visually appealing during display. This packaging format typically uses multi-layer composite materials, combining different materials to create a composite film structure with barrier properties, rigidity, and a desirable appearance. Stand Up Barrier Pouches are compatible with the appearance printing, bag structure, and size specifications required by industries such as food, daily chemicals, and pet supplies. The outer layer can be processed with large-area color patterns, showcasing customized brand effects. The film structure used in the bag body has good formability, ensuring stable performance during production, filling, and sealing processes. Due to the high processability of flexible packaging, manufacturers can flexibly adjust materials, thickness, and bag shape to meet various process requirements in brand marketing, shelf display, and transportation. These packaging bags are also suitable for roll film equipment and finished bag filling equipment, maintaining stable packaging efficiency throughout the supply chain.

1. High Barrier Properties

Stand Up Barrier Pouches utilize a composite film structure, such as PET/VMPET/NY/PE or PET/AL/NY/RCPP, with oxygen transmission rates as low as 0.5–1.0 cc/m²·24h and water vapor transmission rates of approximately 0.5 g/m²·24h. This barrier performance is suitable for packaging needs that require maintaining aroma, humidity, and product activity. The multi-layer structure, after strength testing, ensures integrity during filling and transportation, maintaining stable product quality throughout the shelf life.

2. Strong Support

Stand Up Barrier Pouches can utilize structures such as SUP, self-standing bottom, and eight-side seal, forming a high degree of rigidity through a total material thickness of 120–150 microns. The lower part of the bag body is reinforced with embossing or heat sealing, allowing it to stand stably on shelves. Its stability, tested under load, can reach 1–3 kilograms, making it suitable for various granular, powder, or liquid products.

3. High Customizability

The product supports diverse customization of pattern printing, bag structure, and size ratios. Gravure printing technology can achieve 8–10 color high-precision patterns with color difference controlled within ΔE≤2. Material structures such as PET/PE and OPP/VMPET/PE can be flexibly combined according to product characteristics, allowing Stand Up Barrier Pouches to fully match brand positioning and different filling equipment requirements, meeting market display effects.

4. Reliable Sealing

Stand Up Barrier Pouches are equipped with a resealable zipper structure, with a heat seal strength generally reaching ≥35N/15mm, ensuring that the packaging bag maintains its sealing performance after repeated opening. The zipper area uses high-friction coefficient PE material to improve user convenience. The pressure resistance of the sealing area can pass a 0.8–1.2 MPa sealing test, reducing the risk of leakage.

5. Structural Diversity

This product supports various bag types, including SUP, stand-up pouches, flat bottom bags, and eight-side seal bags, providing suitable shape solutions for different product forms. The material thickness can be customized within the range of 70–180 microns, giving the pouches excellent rigidity and toughness. Through combinations of materials such as PET, NY, and AL, varying degrees of light blocking, oxygen barrier, or puncture resistance can be achieved, making Stand Up Barrier Pouches more suitable for the packaging requirements of various industries.

1. Food Retail Shelves

In food retail channels, Stand Up Barrier Pouches are commonly used for displaying products such as nuts, grains, coffee beans, dried fruits, and candies on shelves. Their self-standing structure enhances display effectiveness, and the composite film material maintains the freshness of the ingredients. The bag size can be customized according to weight specifications, better meeting food industry packaging standards. After the products are placed on the shelves, the appearance design can attract consumer attention and create stronger visual recognition.

2. Cafes and Bakeries

Cafes and bakeries use Stand Up Barrier Pouches to package coffee beans, baking powder, and brewing ingredients. The high-barrier bag effectively reduces oxidation, preserving the aroma of the baked goods. The zipper structure facilitates repeated use, and the convenient opening and closing of the bag improves daily packaging efficiency in stores. The bag material can meet the baking industry's needs for moisture resistance and aroma retention, improving the quality stability of ingredients during storage.

3. Pet Supply Stores

Pet food, freeze-dried granules, and nutritional supplements are suitable for Stand Up Barrier Pouches. Due to the bag's high puncture resistance and good support, it remains intact during transportation and purchase. Pet supply stores often require stable shelf displays, and the self-standing bag structure perfectly meets visual display requirements. The packaging surface can be printed with multi-color patterns, making the product more easily recognizable to consumers and improving sales performance.

4. Personal Care Products Section

In the daily chemical and personal care products sector, products such as laundry pods, bath granules, and skincare powders often use Stand Up Barrier Pouches. The composite film has good moisture resistance and sealing properties, helping to maintain the activity of the contents. Different industries can choose suitable material structures to ensure the packaging bags withstand handling and daily opening and closing operations. High-quality printing can be applied to the packaging surface, making the brand image clearer.

5. Home Storage Scenarios

Home users use Stand Up Barrier Pouches to store items such as tea, spices, dried goods, and cleaning granules, as the zipper opening and closing structure facilitates repeated access. The opaque structure reduces the impact of light in the home environment, maintaining the condition of the contents. The bags can stand upright, making kitchen cabinet storage neater. Different bag sizes can be flexibly selected according to household habits, improving the storage experience.
