How spout pouches are filled?

Apr 17,2023 | Views: 351
Spout pouches are increasingly becoming a popular choice for packaging liquid and semi-solid products. They offer numerous advantages over traditional packaging options such as bottles and cans, including better portability, reduced environmental footprint, and greater convenience for consumers. However, one of the most critical aspects of spout pouches is how they are filled. Spout pouches can be filled using several different methods, depending on the type of product being packaged and the volume of production. 

Aseptic Filling:
Aseptic filling is a specialised method of filling spout pouches that is used for products that require extended shelf life without the need for preservatives. This method involves sterilising the product and the packaging material separately and then filling the pouch in a sterile environment. Aseptic filling is typically used for liquid products such as juices, sauces, and soups. It offers excellent product protection and long shelf life, but it is also the most expensive method of filling spout pouches.

Gravity Filling:
Gravity filling is a semi-automatic method of filling spout pouches that uses gravity to dispense the product. It involves suspending the product container above the spout pouch and allowing the product to flow naturally through a funnel into the pouch. Once the pouch is filled, it is sealed using a heat-sealing machine. This method is suitable for low to medium-volume production runs, and it offers consistent filling accuracy and easy changeover between product types

Manual Filling:
Manual filling is the simplest and most cost-effective method of filling spout pouches, making it an excellent option for small-scale production. It involves an operator manually pouring the product into the pouch through the spout. After filling, the pouch is sealed using a heat-sealing machine. While this method can be time-consuming and labour-intensive, it offers greater flexibility in terms of filling different volumes of pouches and product types.

Piston Filling:
Piston filling is an automatic method of filling spout pouches that uses a piston-driven pump to dispense the product. The pump draws the product from a container and dispenses it into the pouch through the spout. This method offers high accuracy and precision in filling and is suitable for high-volume production runs. It also allows for easy changeover between different product types and offers the possibility of incorporating other features such as vacuum filling or hot-fill capabilities.
