How do you fill a liquid spout pouch?

Nov 01,2023 | Views: 333
Filling a liquid spout pouch, also known as a stand-up pouch with a spout, can be done manually or through automated filling equipment, depending on the production volume and efficiency required. Here's a general guide on how to fill a liquid spout pouch:

Manual Filling:


Prepare the Pouches: Ensure that the liquid spout pouches are set up and ready for filling. Make sure they are clean, undamaged, and positioned properly for filling.

Position the Pouch: Place the pouch in a stable position, typically with the bottom gusset expanded to help it stand upright.

Open the Spout: If the pouch has a resealable spout, open it to create an opening for filling. The spout may have a cap or a removable seal, so ensure that it is open and ready.

Fill the Pouch: Pour or pump the liquid into the pouch through the spout. Take care not to overfill the pouch, leaving some space at the top to allow for sealing and air expulsion.

Remove Air Bubbles: Gently tap or squeeze the pouch to remove any air bubbles inside. This helps prevent the pouch from swelling and ensures proper sealing.

Seal the Spout: After filling, close and seal the spout. If it's a resealable spout, replace the cap or seal. If it's a heat-sealed spout, it may require a heat-sealing process to ensure it's closed securely.

Final Inspection: Check the pouch for any leaks, and wipe the exterior clean if necessary.

Automated Filling:


For higher-volume production, automated spout pouch filling machine is commonly used. The process involves the use of a filling machine designed specifically for liquid spout pouches. Here's a simplified overview of how automated filling is done:

Set Up the Equipment: Install and set up the filling machine, ensuring it is calibrated for the specific pouch size and liquid product.

Load Pouches: Place a stack of empty pouches into the machine's pouch loading station. The machine will pick and open one pouch at a time.

Filling: The machine will fill the pouches with the predetermined amount of liquid, typically with a nozzle or spout that enters the pouch through the spout opening.

Air Removal: The machine may include a feature for removing air from the pouches before sealing. This could involve tapping or vacuuming out the air.

Spout Sealing: If the pouches have heat-sealable spouts, the machine will heat-seal the spouts to close them securely. If they have caps, the machine may apply and secure the caps.

Quality Control: The filled and sealed pouches are usually inspected for any leaks or defects before they are discharged from the machine.

Packaging: The filled and sealed pouches are typically conveyed to a packaging area, where they may be sorted, labeled, and prepared for distribution.

It's important to follow food safety and hygiene guidelines when handling liquid products, especially if they are intended for human consumption. Proper filling and sealing techniques are crucial to prevent leakage and maintain the product's integrity.
