How to make smell-proof bag

Here’s a detailed step-by-step guide for how to make smell proof bag

Materials Needed:

  1. Outer fabric: Choose a durable and tightly woven fabric like nylon, polyester, or canvas. Opt for a dark color to help hide any potential stains or discoloration.
  2. Inner lining: You will need a material that provides an additional layer of odor-blocking protection. Activated carbon fabric or thick Mylar are excellent choices.
  3. Sewing machine and thread: A sewing machine will expedite the process, but you can hand-sew the bag if needed. High-quality thread is essential to ensure the bag’s durability.
  4. Zipper or Velcro: To secure the bag tightly and prevent any potential odor leakage, select a heavy-duty zipper or Velcro strips.
  5. Scissors and pins: For cutting the fabric and holding it in place during sewing.
  6. Measuring tape or ruler: To accurately measure the fabric dimensions.

Step-by-Step Instructions:

  1. Measure and Cut the Fabric: Begin by measuring and cutting the outer fabric and inner lining to the desired size. The size will depend on the intended use of the bag and the quantity of items you wish to store. Leave an additional 1/2 inch on all sides for seam allowance.
  2. Sew the Inner Lining: If you are using activated carbon fabric or Mylar as the inner lining, sew it to the wrong side of the outer fabric. Ensure the odor-blocking material covers the entire interior surface of the bag.
  3. Position the Zipper or Velcro: If using a zipper, place it along the top edge of the fabric on the right side, facing downwards. If using Velcro, position the strips on the fabric to form a secure seal. Pin the zipper or Velcro in place.
  4. Sew the Zipper or Velcro: Using a sewing machine or needle and thread, stitch the zipper or Velcro onto the fabric securely. Go over the stitching a few times to reinforce it, ensuring it is leak-proof.
  5. Fold and Sew the Bag: Fold the fabric in half with the right sides facing each other. Pin the sides and bottom edges together to secure them. Sew along the sides and bottom with a straight stitch, leaving the top (where the zipper or Velcro is) open.
  6. Reinforce the Seams: To strengthen the seams and prevent any potential leaks, sew over the seams again using a zigzag stitch or double stitch.
  7. Trim Excess Fabric and Turn the Bag Right Side Out: Trim any excess fabric from the seams and turn the bag right side out through the open top.
  8. Test the Bag: Test your smell-proof bag by placing strong-smelling items inside and closing it securely. Take a whiff from outside the bag to ensure no odors are escaping.


By following these step-by-step instructions, you can create your own effective and budget-friendly smell-proof bag. Remember to use quality materials, reinforce the seams, and thoroughly test the bag to ensure its effectiveness. Smell-proof bags are not only useful for containing strong odors but also for maintaining the freshness and quality of the contents. Whether you need it for herbs, spices, or other scented items, your homemade smell-proof bag will keep unwanted odors at bay and offer peace of mind.
