Instructions for making your own Nalophan bags

Making Nalophan bags is simple:

1. Cut the desired length of foil from the roll.
2. Fold the sides towards each other at the bottom like a kind of concertina, then fold it inwards once.
3. Now securely close the bottom using a tie-wrap. Pull it tight so that the bag is closed leak-proof. Cut off the unnecessary part of the tie-wrap.
4. Cut a piece of a PTFE hose (tubing), we recommend a length of approximately 14 cm. The inner diameter of the tube should be approximately 7-8 mm.
5. Take the top of the bag and slide the piece of PTFE tubing into it about 8 cm, place the tubing against the side of the bag. Make sure that the piece of tubing remains about 4-5 cm outside the bag.
6. Now fold the top containing the piece of PTFE tubing towards each other like a kind of harmonica. Once everything is together, you can tighten the bag firmly so that the hose is properly secured in the foil.
7. Then also close the top with a tie-wrap. Pull it tight so that the bag is closed leak-proof. Cut off the unnecessary part of the tie-wrap.
8. The bag is now closed at the bottom and top and ready for use.

You can use PTFE caps to close the tubing. We can also supply the PTFE tubing and end caps. Contact us for a quote.
