Under normal storage conditions, unopened products have a shelf life of 12 months.

We provide third-party certification reports detailing the material composition and recycling process.

This is a core question regarding the structural integrity of the packaging. Rest assured, our spout pouches are designed with internal and external pressure changes fully considered. Firstly, we use carefully selected materials (such as nylon) to give the pouch excellent flexibility and burst strength. Secondly, for products requiring long-distance or air transport, we can integrate a small one-way air release valve into the pouch. This valve automatically releases excess gas caused by air pressure or temperature differences, while preventing external air from entering, thus perfectly solving the "bulging" problem and ensuring a flat and secure packaging appearance.

Yes, child safety is a crucial aspect of our product development. We offer spout pouches equipped with child-resistant closures (CRC caps). These caps require a certain amount of pressure and simultaneous rotation, or two consecutive "push and twist" actions to open, and their design meets or exceeds relevant international safety standards. This is essential for packaging household cleaning chemicals, medicines, or certain liquids that pose a risk to children, effectively preventing accidental ingestion and adding an extra layer of safety for families.

For these highly sensitive ingredients, we offer a "high barrier + light-blocking" composite solution. The packaging uses a material structure containing aluminum foil (AL) or a transparent high-barrier silicon oxide coating (SiOx), resulting in extremely low oxygen transmission rate (OTR) and water vapor transmission rate (WVTR), effectively isolating oxygen and moisture. In addition, we offer an opaque white inner layer (such as white PE) or a full aluminum foil structure, and support customized color printing on the outer layer, providing double protection against ultraviolet light and creating a "darkroom"-like protective environment for light-sensitive ingredients, physically extending the shelf life of active substances.

Spout pouches are the "invisible shock absorbers" of e-commerce packaging. Their flexible nature means that when subjected to compression or impact, they absorb and disperse the force through deformation, rather than directly transmitting or breaking like rigid packaging. Furthermore, compared to rigid bottles, they are extremely lightweight, reducing the impact force from drops due to their own weight, and significantly lowering the overall weight and volume of the package, directly saving you on shipping costs. To ensure complete protection, we recommend using cushioning materials such as air bags inside the e-commerce outer box, creating a double-layered protection system of "flexible inner packaging + cushioning outer packaging".
