Stand-up pouches made easy: filling correctly and sealing securely

Stand-up pouches are practical, versatile and popular – but only if they are filled and sealed correctly. It sounds simple, but there are pitfalls: if you don't handle them properly, you risk air getting into the pouch, shorter shelf life or an untidy appearance.

To prevent this from happening, we will show you step by step how to prepare, fill and seal your stand-up pouches perfectly – whether by hand or with a machine.

Preparation: The first step to the perfect stand-up pouch

Gather materials and tools
Before you start filling and sealing your stand-up pouch, make sure you have all the necessary materials and tools at hand.

Everything ready? Our checklist:

• Stand-up pouches: Choose the right size and material for your product.
  
• Filling: Prepare the products you want to package, such as food, dietary supplements, coffee or tea.
• Measuring spoon or dosing device: Use a suitable tool to measure out the contents precisely.
  
• Heat sealer or zip fastener: If your bag has a zip fastener, you can simply close it with this. Pouches without zip fasteners can be sealed securely and airtight with a heat sealer.

A hygienic environment is essential
A clean and hygienic environment is essential to prevent contamination and ensure the quality of your products. Make sure that all surfaces, tools and hands are thoroughly cleaned before you start filling and sealing.

Step by step: filling and sealing stand-up pouches

Filling the stand-up pouches

Manual filling
Manual filling of stand-up pouches is simple and requires only a few steps.

1. Open the pouch zipper and hold it upright.
   
2. Use a measuring spoon or dispenser to fill the pouch to a maximum of 75% of its volume. This filling level ensures that there is enough space to seal the pouch securely.
3. Carefully press out the air before closing the zip.

Important: Be careful not to overfill the bag to avoid damage.

Fully automated filling
A special filling machine is used for fully automated filling, which erects the stand-up pouch and fills it automatically. Here too, the maximum filling level of 75% should be observed. The machine ensures even filling and facilitates the process, especially with larger quantities.

Sealing stand-up pouches

Heat sealing
Heat sealing is a proven method for sealing stand-up pouches airtight. Use a heat sealer to seal the pouches after filling. Ensure that the sealing area is clean and free of filling material to ensure a perfect seal.

Maintain the recommended temperature (between 150 and 200 degrees Celsius) and sealing time to achieve a secure seal. This method is particularly effective for preserving the freshness and quality of the products.

Zipper
The zipper offers a simple and resealable way to close stand-up pouches securely and airtight. Close the zipper carefully after filling to ensure that no air escapes. For additional protection, you can still heat seal the top edge of the pouch. This combines the advantages of a reusable zipper with the security of an airtight seal.

Velcro zipper
The clever alternative to standard zippers: our Velcro zipper not only closes securely, but is also particularly easy to reopen. It does not clog, stick or stick together and can be used up to 130 times – perfect for powders, granulates or products that require clean handling.

Tips & tricks: How to fill and seal your bag even better

Filling volume and weight
Do not overfill the bag, as this can cause damage. Test different filling quantities to find the optimal balance between volume and stability.

Proper storage
Store the filled stand-up pouches upright and protected from direct sunlight and moisture. Ensure that the pouches are not subjected to excessive pressure or stress during transport and storage.

Cleanliness during heat sealing
Ensure that the sealing area is always clean and free of any filling residue. This ensures a perfect seal and prevents the pouch from leaking.
