Driven by the dual forces of fast-paced life and sustainable consumption, liquid spout bags are rapidly replacing traditional bottle packaging with their core advantages of “lightweight design + precise quantity control”, becoming a popular packaging solution in the food, daily chemical, and pharmaceutical industries, and opening the 2.0 era of liquid product packaging.
Core Advantage Analysis
Extreme Lightweight and Portability
The weight is only 1/20 of that of a glass bottle, and the empty bag can be compressed to a thickness of 5mm, saving 60% of storage space. After a juice brand switched to spout bags, the transportation volume per box increased from 48 bottles to 200 bags, and the logistics cost decreased by 45%.
Precise quantity control to prevent waste
The food-grade silicone nozzle is combined with a one-way valve design to achieve ±1ml precise liquid discharge. Customers of a certain infant food manufacturer reported that the product waste rate dropped from 8% to 0.5%.
Full-link safety barrier
Adopting a multi-layer co-extrusion film structure (PE/EVOH/AL), the oxygen barrier rate is <0.5cc/m²/day, and the shelf life is extended to 18 months (12 months for traditional PET bottles).
Typical application scenarios
Food and beverages: fruit puree, honey, sauce
Daily chemicals and personal care: hand sanitizer refills, shampoo travel packs
Medicine and health: oral liquid, probiotic granules
