A flexible packaging pouch spout cap is a fitment component used with spouted pouches (flexible bags that include a molded spout). It serves as the resealable cap that screws or snaps onto the flexible packaging spout to seal the pouch after filling or dispensing. These pouch spout cap are common on flexible packaging for liquids and pourable products.
▲Purpose: to seal the pouch, prevent leaks, enable resealing after opening, and control dispensing.
▲Typical materials: plastics such as polypropylene (PP) or polyethylene (PE), chosen for chemical resistance and compatibility with the pouch contents.
▲Common designs: screw caps, flip-top caps, snap-on caps, tamper-evident caps, and child-resistant variants.
▲Functionality features:
Threaded or push-fit attachment to the spout.
Tamper-evident bands or seals for consumer safety.
Inserts or liners for improved leak resistance and to control flow.
Venting features or flow restrictors for thicker liquids.
▲Typical applications: beverage concentrates, dairy products (liquid creamers), sauces and condiments, baby food purees, liquid detergents, personal care (shampoos, lotions), and industrial fluids.
▲Advantages:
Convenience and reclosability for consumers.
Lightweight and space-saving compared with rigid bottles.
Good barrier properties when combined with multi-layer pouch films.
Lower shipping cost and reduced material use.
▲Considerations when selecting:
Chemical compatibility with product (acids, oils, solvents).
Required sealing performance (leak-proof, shelf life).
Manufacturing compatibility (filling line spout/cap application equipment).
Regulatory and food-safety requirements if for food or pharmaceuticals.
User experience (ease of opening/closing, ergonomics).
Environmental impact and recyclability options.
Based on the inner diameter size of the pouch spout, our flexible packaging pouch spout caps are divided into the following three series:
▲1.3mm~7.8mm pouch fitments
▲8.0mm~16mm stand up pouch spout cap
▲20mm~40mm plastic bag spout and cap
