Custom Retort Spout Pouches | Heat-Resistant Packaging for Soup & Ready Meals
Our custom retort spout pouches are engineered to withstand 121℃ high-temperature sterilization, making them ideal for packaging ready-to-eat soups, sauces, and preserved foods like Luosifen (river snail rice noodle) soup. Featuring food-grade barrier materials, leak-proof screw caps, and vibrant custom printing, these pouches ensure product safety, extended shelf life, and eye-catching brand presentation.
Product Detail
Product Overview
Our custom retort spout pouches are specialized flexible packaging designed for heat-sterilized food products, such as the Luosifen soup pouches shown in the image. Constructed with a high-barrier, heat-resistant composite film (PET/AL/RCPP), these pouches can endure 121℃ retort sterilization without compromising seal integrity or print quality. The leak-proof screw cap allows for easy pouring and resealing, while the stand-up design ensures stable shelf display. Our 11-color rotogravure printing brings your brand artwork—like the elegant golden Chinese-style patterns on these Luosifen pouches—to life with vivid, fade-resistant detail.
As a trusted custom spout pouches supplier, we offer end-to-end customization to meet your retort packaging needs. Learn more about our 8 years of expertise in food-safe packaging on our company profile.
