Food Stand Up Pouches are a type of flexible packaging with a bottom support structure that allows them to stand upright independently after filling. This packaging combines excellent product protection with strong shelf appeal. Their structure typically utilizes multi-layer co-extruded composite materials, with common material combinations including a basic blend of polyester and polyethylene, or incorporating a nylon layer for enhanced toughness and an aluminum foil layer for improved barrier properties. The pouch opening integrates a heat-sealable zipper primarily made of polyethylene, providing convenient and resealable functionality. In terms of manufacturing, it supports high-precision gravure printing and flexible digital printing, ensuring vibrant, durable, and customizable brand graphics and information. Through precise material science and continuous innovation in structural design, Food Stand Up Pouches ensure food safety and extend shelf life while their unique three-dimensional display format becomes an important interface for brand-consumer communication, meeting the modern market's comprehensive demands for packaging functionality, aesthetics, and sustainability.

1. High-Strength Upright Stability

A stable structure is formed through a special heat-sealing design at the bottom, allowing the pouch to stand independently after filling. Tests show that typical self-standing pouches made of PET/PE composite material can withstand over 2.5 kilograms of contents without collapsing, ensuring stable display on shelves and maximizing display area.

2. Excellent Light Barrier Properties

Using composite structures containing an aluminum layer, such as PET/VMPET/PE, effectively blocks visible light and ultraviolet rays. Data shows that the light transmittance of these materials can be reduced to below 0.5%, significantly slowing down the oxidation of fats and degradation of vitamins in food caused by light exposure, thus maintaining the original color and nutritional content of the food.

3. Excellent Low-Temperature Performance

Key material layers, such as polyethylene and specific nylon composite materials, maintain flexibility in low-temperature environments. These materials maintain good crack resistance in low-temperature impact tests at -30 degrees Celsius, ensuring that the packaging does not become brittle during the storage, transportation, and sale of frozen foods.

4. Durable Printing and High Abrasion Resistance

Using gravure printing technology, the ink layer is firmly attached and the colors are saturated. After professional friction testing, the abrasion resistance level of the printed surface can reach above level 4, meaning that the patterns and text information can effectively resist scratching during transportation and distribution, maintaining the brand logo clear and like new.

5. Precise Heat Seal Strength Control

The heat seal strength of each edge of the pouch is designed with differentiated strength. The heat seal strength of the side and bottom seals is usually higher than 35N/15mm, ensuring overall robustness; while the top seal area connected to the zipper uses an appropriate heat seal strength, ensuring initial sealing while allowing consumers to easily open it.

1. Liquid and Sauce Food Packaging

Suitable for edible oils, soy sauce, chili sauce, and other products. The inner PE layer of the packaging offers excellent oil resistance, and the composite structure provides sufficient barrier properties. Combined with a sturdy stand-up bottom design, it facilitates multiple uses and storage in the kitchen, effectively preventing spills and leaks.

2. Powdered and Granulated Beverage Packaging

Designed specifically for milk powder, protein powder, coffee powder, and meal replacement powders. Its superior moisture-proof properties ensure that the powder remains dry and clump-free for extended periods, while the resealable zipper provides continuous protection during multiple uses, precisely meeting the storage needs of these high-value, moisture-sensitive products.

3. Snack Food Preservation

Used for fragile and oxygen-sensitive snacks such as potato chips and shrimp crackers. The packaging's excellent gas barrier properties maintain a suitable nitrogen-filled preservation environment inside, while the stand-up pouch design cushions against external impacts during transportation, reducing product breakage rates, and attracting consumer attention with its large printing surface.

4. Pet Wet Food and Nutritional Paste Packaging

Suitable for semi-liquid products such as wet cat and dog food and nutritional supplements. The material structure has excellent puncture resistance and sealing properties, able to withstand the pressure of the contents and prevent leakage. The stand-up format facilitates pouring and squeezing during feeding, and after use, it can be sealed with a zipper and refrigerated to maintain flavor and freshness.

5. Dry Goods and Grain Storage

Used for common household ingredients such as rice, beans, and dried mushrooms. These Food Stand Up Pouches provide moisture and insect protection, and combined with transparent windows or high-transparency materials, allow consumers to visually check the contents, making them an ideal upgraded packaging solution to replace traditional woven rice and flour bags.
