Seal Plastic Without an Impulse Sealer

Since i am making a DRD pack (Drink version of MRE), i decided to make this instructable seeing that noone else made a similar instructable. It's so easy, you can seal 10 plastic bags per minute! Plus, it's watertight!

Step 1: Gather Your Materials

Materials Needed:
* Candle (or lighter)
* Plastic Bags
* 2 BBQ sticks
* tape
* Common sense

Disclaimer:We will use a flame source in this experiment! take extra precaution and NEVER EVER EVER do this when you are drunk!

free of any legal restrictions, lets begin!

Step 2: Make the Pinching Jig

This is very easy. Just tape the BBQ sticks at the blunt edges like the picture. You can also use an unbroken chopstick

Step 3: How to Use the Jig

Light the candle if you haven't done so

1. Put the object you wanna seal into the plastic bag. Remove the air if you want to
2. fold the end over
3. slide the plastic into the jig
4. use 1 hand to support the object in the plastic while passing the pinched end over the flame. pass it over swiftly, but not too fast. remove from flame if sealed nicely. Use photos to guide you properly

    I would think that once you had the plastic folded and "pinched" you could lay it on a flame-proof surface and pass a torch (e.g. butane) over the pinched end a couple of times to melt and seal the plastic instead of using a candle.

    I was going to make a wooden wakizashi, one of those short katanas, and I wanted to laminate it. Would this let me do so?

    Does the pinched end burn off? Not sure how this works, but it looks like a practical and fast way to seal bags.

    the jig that pinches the plastic kinda seals it while you are melting the plastic and it also prevents the plastic from melting too far in, making a hole. Just remember once it starts melting, put it off the flame immediately

    Good work. I use polyethylene or acetate bags, which I cut and weld simultaneously with the soldering iron. I use a guide, usually straight, over a wooden or cardboard sheet to protect the table. Sometimes I put over the plastic a piece of paper (any dry paper serves, it can be a newspaper sheet or printer sheets) to prevent the melted plastic from sticking to the solder.

    This is how we do it here in the Philippines. I watched my siblings make pili nuts and they package it like that
