Plastic bags are a common household item, but what happens when you want to get rid of them? Can they be shredded? It seems that there is no one-size-fits-all answer to this question. Some people on Reddit have suggested cutting the bags into very small pieces with scissors or using an industrial shredder, while others have proposed melting the bags with an iron and then shredding them. Another idea is to use heated rollers or an oven to melt the bags before reshaping them. However, some have warned against putting plastic bags into paper shredders, as they can jam or damage the machine. So, while it is technically possible to shred plastic bags, it may not be the most practical or efficient method for disposing of them.

Using an iron and baking paper
Shredding plastic bags can be a challenging task, especially without the use of industrial machines or large paper shredders. However, a creative method using an iron and baking paper has been suggested and tested by some individuals. Here is a detailed guide on how to use this method:
This method involves using an iron, similar to the one used for ironing clothes, and baking paper (also known as parchment paper) to melt and fuse plastic bags together. Here are the steps to follow:
- Prepare the Materials: Gather the plastic bags you want to shred and recycle. Also, get two sheets of baking paper for each bag you plan to process. Ensure you have a flat, heat-resistant surface to work on, such as an ironing board or a protected table.
- Sandwich the Plastic Bag: Place one sheet of baking paper on your work surface. Put the plastic bag on top of it, and then cover the bag with the second sheet of baking paper. The plastic bag should be sandwiched between the two layers of baking paper.
- Apply Heat with the Iron: Set your iron to a medium-high temperature setting. Start ironing over the top sheet of baking paper. Move the iron in slow, circular motions or back and forth to evenly distribute the heat. You will need to apply heat for a couple of minutes or until the plastic inside starts to soften and fuse together. Be cautious to avoid applying too much pressure, which could cause the plastic to melt and stick to your iron.
- Fold and Repeat: Once you've applied heat to one section, fold the 'sandwich' (the plastic bag and baking paper) and iron the next section. Continue this process of folding and ironing until you've covered the entire bag, and the plastic has fused together sufficiently.
- Cool and Check Thickness: After ironing, set the 'sandwich' aside to cool. Once cooled, carefully peel back the baking paper and check the thickness of the fused plastic. If it's not thick enough, you can repeat the process by layering multiple fused sheets of plastic between baking paper and ironing again.
- Shred the Fused Plastic: Once you have achieved the desired thickness, you can shred the fused plastic by cutting it into thin strips using scissors or a rotary cutter. Be cautious as the plastic may be sharp along the edges. You can now use the shredded plastic for your desired purpose, such as filling or crafting.
This method is a time-consuming process, especially if you have many plastic bags to shred. However, it provides a creative way to recycle plastic bags without the need for expensive industrial equipment. Remember always to take the necessary precautions when working with heat and sharp objects.

Melting in an oven
Melting plastic bags in an oven is a popular method of recycling them. It is important to note that melting plastic at home can be harmful to the environment and your health if not done correctly. Burning plastic releases toxic fumes, so it is important to ensure proper ventilation.
To melt plastic bags in an oven, first, collect all the plastic bags you can get. Plastic bags are usually made of LDPE (low-density polyethylene), which melts at 248 °F (120 °C). Preheat your oven to this temperature.
Next, place the plastic bags in a heat-proof container that will fit in your oven and hold the melted plastic. Some options include a cheap sheet pan or a ceramic tile. Ensure that the plastic does not spill onto the oven's surfaces, as it can be difficult to remove.
Once the oven is preheated, place the heat-proof container with the plastic bags inside and turn on the oven's fan. Keep the windows open to ensure proper ventilation and avoid inhaling any toxic fumes.
Monitor the melting process closely. Melting plastic in an oven takes patience, as it will gradually melt. Watch the plastic through the oven window to ensure it does not burn. If the heat is too high, the plastic will smoke and burn quickly.
Once the plastic has melted, remove it from the oven using oven mitts. Be careful not to spill the molten plastic. While the plastic is still hot, you can pour it into a mold to shape it. You can use a pre-made heat-resistant mold or create your own, for example, from wood.
If you want to cut the plastic into a new shape, let it cool in the melting container before shaping it. You can then cut and sand the hardened plastic into your desired shape.

Industrial shredders
Plastic bags can be shredded, but not using a paper shredder. Paper shredders are not designed to handle plastic, and the plastic will tangle and jam the machine. However, there are various other methods to shred plastic bags.
There are different types of industrial shredders, each designed for specific materials. Single-shaft shredders are suitable for films, bags, and bottles, while dual-shaft shredders are used for pipes, pallets, and car parts. Four-shaft shredders can handle mixed or contaminated plastics. Blade design is also important, with hook blades for thick sheets, claw blades for films, and flat blades for granules. A uniform particle size is crucial to preventing blockages, reducing energy consumption, and improving product consistency.
In addition to industrial shredders, there are other methods to shred plastic bags. One method involves using an iron to melt the plastic bags between two sheets of baking paper. The plastic can then be folded, ironed again, and repeated until the desired thickness is achieved. This process works for both HDPE and LDPE bags. Another method is to use heated rollers to pass the bags through, melting them down. However, this requires evenly heating the rollers to the correct temperature, which can be challenging.
Overall, industrial shredders play a crucial role in efficient plastic recycling, turning bulky waste into smaller, uniform particles that are easier to process. They enable companies to work more sustainably and reduce their environmental impact.

Paper shredders
It is generally not recommended to put plastic bags into a paper shredder. The plastic can tangle and gum up the shredder mechanism, causing damage and requiring tedious clean-up. Instead of using a paper shredder, an alternative method for handling plastic shipping labels is to cut them out precisely, spray them with denatured alcohol to turn them white, and then dispose of them with regular household trash.
However, there are some workarounds if you want to use plastic bags with a paper shredder. One suggestion is to use a plastic bag to collect the shredded paper instead of putting the plastic bag through the shredder. Choose a bag that corresponds to the inside dimensions of the bin, ensuring it is large enough to reach the outside of the bin to prevent it from accidentally getting near the cutting edges. Using a bag inside the bin can make it more difficult to visualize the shred level, so it is important to physically check the level more frequently.
Another method to make plastic bags shreddable is to use an iron. Place the plastic bag between two sheets of baking paper and iron it. Fold and iron again, repeating the process until the plastic is thick enough to shred. This method can be time-consuming, but it has been tested and found to work with HDPE and LDPE bags.
Overall, while it is possible to shred plastic bags with certain techniques or by using them to collect shredded paper, it is generally not advisable to put them directly into a paper shredder to avoid potential damage and maintenance issues.
