How to Repurpose Used Ziploc Bags into Reusable Sandwich Bags


Reusing old Ziploc bags is a great way to reduce plastic waste and save money. With just a few simple steps, I can give used Ziploc bags a new life as reusable sandwich bags. In this article, I will provide a step-by-step guide on how I repurpose used Ziploc bags into reusable sandwich bags.

Gather Used Ziploc Bags

The first step is to collect used Ziploc bags that are still in good condition and do not have any holes or tears. I save all my used Ziploc bags by rinsing them out and hanging them up to dry after use. Some tips for gathering usable Ziploc bags:

  • Check pantries, fridges, and freezers for any Ziploc bags used for storing food.
  • Look for bags that have been used for packing snacks, sandwiches, or fruits/vegetables.
  • Avoid bags that stored raw meats, fish, or greasy foods which can leave residues.
  • Make sure bags are completely clean and dry before reusing.

How to Clean Used Ziploc Bags

Before reusing, it’s important to thoroughly clean the used Ziploc bags:

  • I start by rinsing the bags with hot water to remove any food residues.
  • Next, I wash them with mild dish soap and a soft sponge.
  • I pay special attention to cleaning the seals and corners of the bags.
  • Finally, I let the bags air dry completely before sealing them for storage.

Proper cleaning removes germs, grease, and odors from used bags. It helps extend the life of the bags as reusable sandwich bags.

Steps to Repurpose Ziploc Bags

Repurposing used Ziploc bags into reusable sandwich bags only takes a few easy steps:

1. Cut Along Seals

The first step is to cut along the existing seals of the Ziploc bag. I use scissors to carefully cut and open up the seals on three sides. This will create a large, flat plastic sheet.

2. Cut Into Squares

Next, I cut the plastic sheet into square shapes approximately 6-inches across. This size is perfect for sandwich bags. The number of reusable bags I can get depends on the original size of the Ziploc bag.

3. Seal the Sides

After cutting the plastic into squares, I use an iron on the lowest heat setting to seal the open sides. This creates a pouch shape and completes the reusable sandwich bag!

I place the bags between two pieces of parchment paper and run the iron along the open edges to melt and seal the plastic. I go slowly to ensure the seals are airtight.

4. Add Labels or Decorations (Optional)

To distinguish my repurposed sandwich bags from regular Ziplocs, I like to add labels or decorative touches like stickers. Getting creative with labels helps identify whose lunch bag is whose in a family.

And that’s it! With these four simple steps I can repurpose used Ziploc bags into reusable sandwich bags. My homemade sandwich bags are durable, leakproof, and budget-friendly.

Tips for Using Repurposed Ziploc Bags

Here are some handy tips to get the most use out of repurposed Ziploc bags:

  • Label the bags with names or uses to avoid confusion. Permanent marker works well.
  • Don’t overstuff – avoid puncturing the repurposed bags with sharp items.
  • Check for damage before reusing and discard any with holes or tears.
  • Clean after each use – wash thoroughly and let dry before sealing again.
  • Store the reusable bags together in one place so they don’t get mixed up with regular Ziplocs.

The Benefits of Reusing Ziploc Bags

There are many great benefits to repurposing Ziploc bags into reusable sandwich bags:

  • Saves money – one Ziploc bag can make multiple reusable sandwich bags.
  • Reduces plastic waste – gives used bags a second life before recycling.
  • Environmentally friendly – reusing plastic bags decreases demand for new bags.
