how to create your own foil balloons - mylar sheets for sale
Foil balloons are made of metal-treated plastic sheets.
NASA created the first foil balloon for space missions.
They make balloons with Merah.
You can create your own foil balloon at home using thermoplastic foil.
Nylon and polyethylene foil are thermoplastic.
These foils can be sealed together with heat.
Heating melts the plastic, and then after cooling, the material is solidified into one layer instead of two layers.
Avoid the use of foil made of hot solid material, because the heat cannot melt the foil, so no seams can be generated.
Cover the table with two layers of craft paper.
This will protect the table from any damage.
Track the balloon on a piece of paper.
You can draw any shape you want.
Because the balloon is 3D, the pattern needs to be larger than the actual balloon.
To determine the actual size, you must know that the circumference of the balloon is half the circumference of the pattern when it is inflated.
Therefore, the pattern must be 50% larger than the actual balloon.
Select a point on the pattern for the fill point.
It will be a neck 1 inch wide and 4 inch long.
Cut the pattern with scissors.
Push the foil out of the table with nylon side up.
Tape One side down, stretch the foil, and then tape the other side.
Foil needs no wrinkles when recording.
Put another foil on the top of the first piece.
The nylon face down this time.
Tape edges to ensure no wrinkles on the foil.
Place the pattern on the top of the foil and follow around the pattern using a permanent mark.
Insert the heated iron and test if the sealing heat is good.
The temperature of all irons is different.
Test heat with foil scraps.
Press the hot iron on a small piece of foil folded up.
Let the foil cool and try to peel the seam off.
If the seam is brittle or melted, the temperature of the iron is too hot.
If the iron is not hot enough, the seam will crack.
Seal the balloon as soon as you find the right temperature.
Put a wax paper on the outline.
Press hot iron around the outer edge of the profile.
Start ironing on one side of the filler neck and then work on the other side of the filler neck.
Do not seal on the neck of the filler, otherwise you cannot inflate the balloon.
Wax paper is easier to iron and the seams are more beautiful.
Put the iron on the floor when you're done, but don't unplug it or let it cool.
Insert a heat knife and let it heat up.
To cut off the foil, you want a higher temperature than the iron.
Test heat with foil scraps.
The knife needs to be hot enough so that it can cut off the foil by melting the foil.
Cut off the balloon with a hot knife.
Cut along the outer edge of the seam, leaving about half an inch of the seam on the balloon.
Move the knife slowly and make sure you're cutting two pieces of foil.
Avoid chop marks by bending in any area where the direction changes.
Chop marks are easy to tear.
Peel the balloon off the table.
Take your time to avoid tearing.
Remove the remaining foil from the table and put the balloon upside down and put it back on the table.
Check the back seam.
Re-seal if they bubble, gather or are not sealed
Iron the seam as shown in step 7.
Inflate the balloon with helium or air.
The expansion is slow due to excessive expansion or rapid expansion that causes the seam to fall off or the balloon to tear.
Once the balloon is inflated, quickly seal the filler neck with an iron.
Remove the iron and knife and clean up the work area.
