HOW TO fuse plastic bags

I like to use fused plastic, because the material is easily available and versatile. I use it in quite a few of my projects.

I made a cardboard tray and lined it by fusing a plastic bag directly on the cardboard. I also made the handles for the tray by fusing plastic around a nylon cord. My junk mail and magazine vases have removable fused plastic linings. This lets me fill them with water for fresh flowers. I created plastic versions of my origami accessories with squares of fused plastic. These are great, because they’re more durable than the paper versions. I even use this technique to wrap gifts.

Fused plastic is waterproof, flexible, easy to work with, and a cinch to make. Let’s get started.

Supplies

  • 1 plastic bag
  • 1 pair scissors
  • wax paper, parchment paper, or copy paper (Forego used copy paper. Ink from the paper may transfer onto your iron or the plastic. Use new copy paper. You can always print on the paper after your done using it to your fuse plastic. I’m going to use wax paper because it’s what I have in my kitchen at the moment.)
  • 1 clothes iron
  • 1 towel, ironing board

How-To

  1. First, cut off the bottom seam of the bag.
  2. Now cut off the handles.
  3. Flatten out the bag.
  4. If you’re using a towel, layout it out on your work surface. I prefer using towels, because I find it easier to fuse sheets of plastic on a larger surface.
  5. If the plastic bag has printed graphics, turn the bag inside out. This prevents the bag’s ink from transferring onto your waxed paper or iron and smudging everywhere.
  6. Lay a protective sheet of wax, parchment, or copy paper underneath the bag.
  7. Place second a sheet on top.
  8. Set the iron on polyester or rayon and turn of the steam.
  9. Iron the plastic bag, running the hot iron from the center outwards. This prevents air from getting trapped in the bag and forming bubbles. If you do find bubbles you can pop them with a pin and iron over them. Keep the iron moving at all times running over the entire surface two to three times. The plastic bag will smoothen and the protective sheet will adhere to the plastic bag. Be careful to run the iron over the protective sheet only and not directly on the plastic bag, otherwise you may melt the bag onto your work surface and your iron.
  10. Turn the plastic bag over while keeping it sandwiched between the protective sheets.
  11. Iron this side of the plastic bag.
  12. Allow the fused plastic to cool.
  13. Once it’s cool to the touch carefully peel off the protective sheets. If the plastic isn’t fused completely sandwich it between protective sheets and iron again.
  14. Now you have a two-ply sheet of fused plastic. You can make it thicker by ironing another plastic bag onto it. Remember to sandwich the plastic between protective paper before ironing!

Useful tips

  1. Keep the scraps from the bottom and handles. You can place them on top and fuse them with the main part of the plastic bag too, so there’s no need to throw anything in the trash.
  2. Ironing your plastic a little longer will cause it to melt and form holes. This can make for an interesting texture, but be careful not to burn it!
  3. You can fuse multiple bags together to make an even thicker and durable plastic sheet. Fuse additional plastic bags by stacking one on top and fusing it completely before stacking on another. If you try ironing together a stack that’s too thick, the iron may not be able to fuse the bags in the center of the stack
  4. Cut out shapes from different colored bags and fuse it on fused plastic sheet for like an appliqué effect.
  5. I made my plastic origami accessories using four-ply fused plastic. You can even go up to six or eight-ply.
  6. There will be minimal fumes, so keep the door to your work room open or crack open a window.
  7. Here’s a tip from talented crafter, Arely. You can use clear plastic bags to laminate paper. If you use a clear plastic bag, be careful because it tends to melt faster. After fusing, the plastic will still be clear, but it will have a matte finish.
  8. Becky, the plastic crafting maven of Crop Rotation, says sewing plastic is like sewing regular fabric, but can be a little more slippery. Use denim sewing machine needles and general purpose yarn or denim yarn.

in My Art

My art piece, “Gaylien 00“, draws on superhero comic books and my love of reclaimed materials to humorously reframe my experience growing up in the closet.

The iridescent aura that surrounds the central figure is primarily crafted using the fused plastic and iridescent paint. By manipulating the wrinkles and varying the amount of fusion I created textures to capture the light and create the suggestion of light rays.

Creator Spotlight

Becky, a college math professor with a crafty side, sent me a collection of projects. In her fused plastic projects, she uses rare bags, especially ones that friends or family bring back from other countries. She’s made a brilliantly graphic messenger bag and iPad sleeve by carefully composing a collage of prints. Check out more of her math influenced creations at Crop Rotation, and see what inspires her on her Pinterest.

    1. That’s a cool idea. Though I wonder if stitching patches together would create leaky holes. Perhaps you can fuse additional plastic over the stitching, or just use an iron for your entire project.

      Thanks for visiting and taking the time to write, Debra!

      1. Hello, Bao! It’s so cool to see that the plastic fusion questions and ideas keep rolling in! 🙂

        I can’t thank you enough for sharing my passion with your fans. Just an update, I continue to make the fused plastic, but only with interesting bags with logos or bags given to me by friends & family from their international travels. I moved more into keeping an eye out for ready-to-sew upcycling materials like thicker plastic, coffee sacks and 2nd-hand sweaters (that I felt… oooooo! I’d love a chance to share that with your fans!). I’m happy to share my knowledge on those things or sell bolts or pieces of my materials — they’re goin’ like hotcakes on Listia (my new fave… like ebay, but the currency is in the form of CREDITS, not $. I LOVE IT!). More about these passions of mine on:

        P.S. I’ve recently resigned from higher ed teaching to spend more time w/younger students and educators. This way, I’ll have more time for my children’s book series… 2 published, more written!?) and for classroom applications of math & science through upcycling and cooking. Love. IT!

  1. This is great, I can see a lot of possibilities! Wallets,bags, shower curtains, tiles…etc and you could ‘draw’ on the plastic using different colors of plastic bags! Only if we are not using reusable bags.
    Does it produce toxic smell when ironing?

    1. Good question!

      The plastic does off-gas. Try to avoid completely melting it. Iron the plastic enough just to fuse it. If you want to make a thicker sheet of fused plastic, build up with single layers instead of trying fuse several layers at a time. You’ll be able to avoid overheating and melting top layers of plastic. And, of course, work in a well-ventilated space!

      Thanks for visiting and taking the time to write and ask a great question, Olive. I can’t wait to see what you come up with!

  2. I’ve been looking for a way to repair the wings on my old fairy dolls. Buying plastics is too expensive and don’t look as good, but this worked like a charm and it looks right out of the package! Thank you so much!

  3. Has anyone tried working with the reflective silver emergency blankets? I wanted to use them in a school related costume project, and thought they would be neat because you have a lot material to work with but I’m having trouble getting them to fuse (even on high heat). I’ve been using wax paper to iron through. Any ideas?

    1. Hi Peter. An average household iron won’t get hot enough to melt mylar blankets. You’ll have to do it the old fashioned way and stitch them together. If you’re trying to make the mylar thicker try fusible interfacing. I’m not sure if it will stick to to the mylar to so you’ll have to experiment with a swatch. You can also try a spray adhesive to glue two mylar blankets together. But again I would experiment with a swatch to make sure it sticks and that the material doesn’t degrade. I hope that helps.

      Thanks for visiting and taking the time to write! Good luck with the school project! Tell me how it goes!

    1. It sure is. You’ll notice that different plastics feel different, and they will also melt differently. The candy wrappers I’ve seen are quite small and thin, so You won’t need to iron them very much to fuse. Experiment, give it a go, and tell me how it goes! I’d love to put your results in the tips section of the tutorial! Thanks for taking the time to writing, Abi!
