Introduction: Basics: Join Plastic - #4, Shrink-wrap 1
here is how you can make your own shrink-wrap. for all kind of applications. from ´trash´.
for demonstration-purpose lets just wrap two fishcans
(this is part 1. a second, differen,t technique will follow whenever the muse kisses me)
Step 1: The Almighty... Plastic-bottle:
the raw-material for your wrap is the boundless gift/curse sent from the gods:
p.e.t.-plastic, number 2.
cut out a piece that suits your plans
Step 2: Create a Loose Wrap
get a piece of plastic for whatever you want to wrap (remember: here 2 fishcans).
form a loose closure (with extra margins).
with a few quick holes/burns done vía a soldering-iron make sure it won´t open.
Step 3: Create a Seam
with the soldering-iron (or, as i always point out: any similar object you can heat up in a fire etc) melt down the plastic into a tight weld. make sure the weld/seam is strong (there will be a lot of tension on that sucker once we go live shrinking - just like in the real life with shrinks).
Step 4: Ready for Heat:
to finish off the shrink-wrap you need some source of heat.
here, for simplicity, i ´cheat´ and use a ´baby´-heatgun. (but, again, if you are out in the ´wild´ or face an emergency: the heat from a fire properly transfered will do the trick, too)
anyhow, carefully start shrinking the p.e.t. down
Step 5: Done
trim off the magins if yo like.
..... done.
