Spouted retort pouches use food-grade composite films (such as PET/PE, PET/AL/PE) as the base material, with layers tightly bonded through a high-temperature lamination process. They are equipped with food-grade PP high-temperature-resistant spouts (capable of withstanding 121°C high temperatures) and feature three core functions:?high-temperature retort sterilization,?convenient access via spout, and?reusable sealing protection. No need to cut open the pouch for heating or consumption, making them widely used in food packaging scenarios requiring "heating + repeated access"—such as instant porridge, thick soups, sauces (e.g., tomato sauce), wet pet food, and meal replacement shakes. They are particularly suitable for fast-moving consumer goods (FMCG) retail and household demand for convenient meals.
Compared with regular non-spouted retort pouches and ordinary food bags, their core performance is significantly improved:
- Convenience of access is improved by over 80%: Regular non-spouted retort pouches require cutting open to pour out contents (prone to spillage), while the spouted design allows one-handed opening and closing; after heating, contents can be consumed directly through the spout without additional containers;
- Reusable sealing performance is enhanced by 70%-90%: Ordinary retort pouches lack a sealing structure after opening, leading to easy contamination and spoilage of contents. The spout enables repeated screw-cap sealing, extending the freshness period by 3-4 times after opening;
- High-temperature stability is increased by 30%-50%: Ordinary food bags (e.g., PE bags) cannot withstand temperatures above 100°C and are prone to deformation and liquid leakage when heated. Spouted retort pouches can withstand 121°C high-temperature retorting (suitable for commercial sterilization) without cracking at the junction of the pouch body and spout;
- Shelf life of contents is extended by 50%-70%: The composite base material + spout sealing form a "oxygen barrier + moisture barrier" dual protection. The oxidative spoilage rate of instant soups is reduced from 40% (with ordinary food bags) to below 10%, and the caking rate of sauces is decreased by 85%;
- Scenario adaptability is boosted by 60%-80%: They can be directly placed in a steamer or microwave for heating (with the spout cap removed) and can also be stored in the refrigerator, suitable for multiple scenarios such as home, office, and outdoor use. Ordinary retort pouches need to be transferred to containers for heating, with significant scenario limitations.
Compared with regular versions, it additionally has three core advantages:
- Integrated "retort + spout" functions: Ordinary non-spouted retort pouches only enable high-temperature sterilization and require cutting for access; ordinary spouted bags are not high-temperature resistant and cannot be retorted. This product solves the pain points of both "sterilization protection" and "convenient access" simultaneously, serving as a complementary functional upgrade of the two;
- Food-grade high-temperature resistance details: The spout is made of retort-resistant PP material, which has no odor and does not release harmful substances after retorting. The junction passes pressure testing (no liquid leakage after 30 minutes of retorting at 121°C), making it safer than ordinary spouted bags that are only "room-temperature compatible";
- Balance of brand value and practicality: The surface of the pouch’s composite film is flat, allowing clear printing of brand logos, nutrition fact tables, and heating instructions, with the spout not blocking key information. It also supports customization of transparent windows (to check the state of contents), adding display value beyond the "pure protection" attribute of ordinary retort pouches.
