Stand Up Pouch With Spout Reshape Flexible Packaging: Leads with Quality and Innovation

In the wave of changes in the packaging industry, spout pouches have quickly become the focus of the market with their innovative design and practical value. RJ PACK has become an important promoter in this field with its technical and quality advantages.

Innovative Structure Shapes New Packaging Forms

As an upgraded product of stand up pouch, spout pouches break through the limitations of traditional packaging with the combination of "bottom support + top spout". The bottom self-supporting structure ensures that the packaging stands firmly, and the top spout enables convenient sucking. It can still remain stable after sealing, which is particularly suitable for liquid and semi-solid products. This form of flexible packaging is more hygienic than zipper bags and more economical than bottles. It is widely used in beverages, detergents, sauces and other categories.

RJ PACK: Technology Drives Quality Upgrade

We relies on internationally advanced equipment such as HP indigo25K digital printing presses, integrating digital, flexographic, and gravure printing technologies to provide full-process flexible packaging solutions. Its products have passed the US FDA and EU standard certification, and won the title of National High-tech Enterprise in 2021.

In terms of production technology, the company strictly controls the manufacturing process of spout pouches:

Accurate material selection to ensure performance

The spouted pouch adopts a multi-layer composite structure. The outer layer uses OPP, PET, PA and other materials according to the product characteristics to achieve personalized printing; the middle layer uses high-barrier materials such as PET and aluminum foil to meet the product technical requirements; the inner layer uses low-temperature heat-sealing materials such as PE to ensure sealing and anti-pollution performance.

Exquisite Technology

Printing: High-temperature resistant ink is used at the nozzle, and matte oil printing is avoided to prevent anti-sticking and ensure the heat sealing effect.

Composite: According to different needs, suitable glue is selected, and high-temperature retort pouch use professional-grade glue to reduce the risk of bulging.

Heat sealing: Comprehensively consider factors such as materials and film thickness, accurately control temperature, pressure and time parameters, and ensure heat sealing strength and flatness.

In terms of substrate selection, we systematically evaluates the material's puncture resistance, flexibility and other indicators based on product capacity and shape. Liquid packaging often uses structures such as PET/NY/PE, combined with tough materials to effectively prevent leakage at the nozzle. The application of aluminum foil further improves the quality and freshness of the packaging.

With its technological and quality advantages, the stand up pouch with spout produced by RJ PACK are sold all over the world, providing manufacturers with cost-effective packaging solutions. In the future, we will continue to innovate and help the packaging industry reach new heights.
