It is important to know that your heat sealer is performing as it should be. A poor seal can lead to compromises in the sterility of the contents you are sealing.  It is for this reason that we recommend regular testing of your sealed pouches.

In addition to producing high-quality heat sealers, Hawo also manufactures several different types of test systems for checking the integrity of your heat-sealed pouches. The Seal Check, Ink Test, and Ink Test PRO EU are three ways of checking the quality of a seal. Furthermore, users can combine one or more of the options below with a periodic pouch destruction test which can be carried out by one of our in-house, Hawo trained engineers.

The InkTest PRO EU is an innovative take on the standard ink test. It is used for the routine testing of all four sides of the pouch and fully complies with ISO 11607-1 and ASTM F1929. Using the InkTest PRO EU is easy. Users simply place one of the aluminium foil sachets into a pouch and seal it as normal. Then the sachet is squeezed until it bursts and the ink is ejected. The ink then moves around inside the pouch and any flaws in the seal seam will become immediately visible.  The Hawo InkTest PRO EU is supplied in a box of 30 sachets.

The InkTest PRO EU is easy to use and much cleaner than conventional pipette ink tests.

This is the classic ink test using a pipette and bottle of ink used for Tyvek® (HDPE) material. It complies with ISO 11607-1 and ASTM F1929 and allows users to clearly see any defects in the seal. The ink test can be used on Tyvek® (HDPE) paper/film pouches.

The Hawo InkTest PLUS 2.0 is supplied with a 1 x 75ml bottle of red ink and 20 disposable pipettes.

The InkTest PLUS 2.0 is Triton-X free. This is a requirement for use in the UK. Triton-X been banned in the European Union and the United Kingdom since January 2021.

The Seal Check by Hawo consists of 250 sheets of special indicator paper. The paper is dark in colour and has a unique grain to it. This means that when sealed within a paper/film pouch, any creases or gaps in the seal are clearly visible. The Seal Check can be used for routinely checking the integrity of pouches produced and can be kept for your records.

The Hawo Seal Check is available in two versions:

• Seal Check Med is the most popular Seal Check and is used for standard paper/film pouches.
• Seal Check HDPE is suitable for Tyvek® (HDPE) paper/film pouches and also for transparent pouches.

Both types of Seal Checks are 175mm in length and consist of 250 sheets. Results can be compared to the reference card available in the Downloads section below.
