Melt Plastic Bags Into Tea Light Candle Holder




I wanted to see how I could transform everyday plastic bags into something else.

This is a neat way to reuse them, but it's really bad for your body / environment.

The fumes from baking this made me nauseous!!!!!

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Gather Supplies

You need:

  • A baking sheet
  • A container to mold your plastic bags in x 2 --> use ones that can stack on top of one another
  • Foil
  • Plastic bags

Step 2: Bake Your Plastic Bags

  • Line your baking sheet with a couple pieces of foil, just so the plastic doesn't melt onto the sheet.
  • Place plastic bags onto sheet.*
  • Set the oven to 350 degrees F and put in oven.
  • *Tip: Tie the plastic bags into knots so that they're not all over the place and are more compact.

Step 3: Setting Up Mold

  • After the bags look sufficiently melty, take your baking sheet out of the oven. You might have to do this a couple of times to get the amount of melted plastic you need. So either use a lot of baking sheets or use a deep dish to hold your plastic bags in.
  • Get your mold ready:
    • To prepare your mold, line it with foil!
  • Using chopsticks, tongs, or gloves, transfer the melted bags into the mold.

Step 4: Molding Part 2

  • Place another sheet of foil on top of the melted plastic in the mold.
  • Press down with your hand..
  • Then, use a container that fits into your mold (in my case, I used an identical tart tin) to press the plastic bags into the container holding your melted plastic to form a bowl.

Step 5: Molding the Part That Holds the Candle

  • After pressing the melted plastic, take off the top layer of foil
  • To create the part that holds the candle, I used a beer bottle to press into the melted bags again. Do this while it's still moderately warm and pliable.

Step 6: Freeze

Place everything into freezer so it can harden!!!

Step 7: Final Steps

Take out of freezer and use exacto to trim wayward parts off.


Place the tea light into your new candle holder~~~

    OK to be nice and positive Let me help you out. I have and do projects with this material all the time so I have learned somethings. You need to not heat at over 350* f If the cups I see in the picture are made out of what I think they are that is part of your smell and sick thing don't use plastic to melt plastics. use metal cook wear only or metal at least. I make wood substitute out of grocery bags all the time as well as cool parts toys and other stuff, so I've done my share of experimentation with heat settings, dishes to cook in, tools to cook with ( toaster irons are some of the best as long as they don't heat over 350*) there are a couple videos on you tube that feature this subject you might like. Be safe keep the temps down don't cook plastic in plastic, be patent and enjoy.

    Thank you for your insights. The mold I am cooking it in is actually metal bakeware.

    if you drop it into a bath of cold water it will cool faster. use cooking spray to line molds. it will release great. tin foil can be a real pain to remove from cast, if you flash cool it in water it will release quicker and cleaner. also if you use metal molds you can place them into over and direct cast your items. Be safe.

    Thinking of doing this but would have to build the solar cooker first, not willing to risk these fumes indoors
