A heat sealing iron and some common household items are all that’s needed to build your own homemade packraft
The heat sealing iron you’ll need for your homemade packraft can be purchased in the UK relatively cheaply.
To make our prototypes we began using a Clover Mini Iron II, however we found the iron struggled to maintain the required temperature and we would not recommend this model for making a self-build packraft (at least in the UK as it is only 25W here)
We have since used both the Jamara Pro Star iron and the Prolux Digital Iron. We’ve had far more consistent results heat sealing with both of them, although it should be mentioned they are far larger and slightly inconvenient to work on the smaller seams and tight areas.
Whatever heat sealing iron you use, ensure it can reach 220 degrees and can continuously operate around this temperature as this is the approximate temperature required to activate our TPU fabrics.
Size is also an important aspect and the iron head must be small enough to work on small seam lines. For this reason, a household iron is not suitable.
The only other tools you’ll need to make your homemade packraft are a pair of scissors, some sticky tape and a curved surface such as a bowl for draping the fabric over for the tube seams.
