Plastic wrap: a cheap, portable solution for keeping sandwiches fresh
Plastic wrap is a thin, flimsy, plastic-like material that is popular for storing sandwiches and keeping them fresh. It was discovered in a lab by accident in the 1940s and gained popularity in the 1950s due to its effectiveness in food storage. Today, there are numerous brands of plastic wrap available worldwide, made from materials such as PVDC, PVC, and polyethylene.
While plastic wrap is cheap and portable, making it convenient for storing and carrying sandwiches, it has significant environmental drawbacks. Plastic wrap contributes to the global plastic pollution crisis and is challenging to recycle. It is often made from potentially harmful chemicals, which can be released into the environment as it breaks down.
To address these concerns, some companies offer compostable sandwich containers made from materials like PLA. These containers are designed to showcase sandwiches attractively while keeping them fresh and secure during transport. Additionally, individuals can create fused plastic sandwich wraps by cutting, ironing, and fusing plastic shopping bags between layers of parchment paper. This DIY approach reduces waste and provides a reusable alternative to single-use plastic wrap.
Overall, while plastic wrap is a cheap and portable solution for keeping sandwiches fresh, its environmental impact has spurred the development of more sustainable alternatives, including compostable containers and reusable fused plastic wraps.

Plastic pollution: the negative environmental impact of plastic wrap
Plastic wrap, also known as Saran Wrap, was discovered in a lab by accident in the 1940s. Today, there are more than 100 brands of this thin, transparent plastic film available to consumers worldwide. It is popular due to its low cost and portability, and its ability to keep food fresh for longer.
However, plastic wrap has several negative environmental impacts. Firstly, it contributes to the global plastic pollution crisis. As a thin, flimsy material, plastic wrap is difficult to recycle; it clogs recycling machines unless specialized equipment is used. Even when it is recycled, the process is more costly than using virgin materials. As a result, much plastic wrap ends up in landfills or incinerators, where it releases a highly toxic chemical called dioxin, according to the World Health Organization.
Secondly, plastic wrap is made from potentially harmful chemicals, which can break down in the environment and contaminate food. A 1998 study by Consumers Union found DEHA levels in plastic-wrapped foods higher than what is considered safe by European regulatory agencies. A 2021 study found that DEHA triggered brain and heart injuries in rats, although further research is needed to understand the risks for humans. Other dangerous chemicals found in plastic wrap include phthalates, which are a category of molecules that contains carcinogens.
In marine environments, plastic wrap contributes to the plastic pollution crisis in a unique way. Scientists have found that PVC and PVDC, two types of plastic used in plastic wrap, are particularly good at picking up bacteria and metals. These contaminated pieces of microplastic are then ingested by fish, causing harm to marine life.
While plastic wrap does serve an important function in preserving food and reducing waste, its negative environmental impacts are significant. Consumers can reduce their use of plastic wrap by seeking alternative food storage methods, such as reusable containers or biodegradable wraps.

Recycling plastic: how to reuse plastic waste at home
Plastic is everywhere, and it's harmful to the environment. Plastic doesn't biodegrade, it just breaks down into smaller pieces, and the toxic chemicals that leach out of it get into our environment, food supply, and ultimately, us. Reducing single-use plastics is one of the biggest environmental challenges of our time.
Reuse plastic bottles
- Plastic bottles can be reused to hold kitchen utensils, pencils, or buttons.
- They can be used as snack bowls for parties.
- Punch holes in the sides and bottom of 2-liter soda bottles and bury them next to plants to create a drip irrigation system.
- Make hanging planters with any size bottle.
- Make a homemade pencil case for kids.
- Keep a clean plastic bottle in the kitchen to separate egg yolks.
- Make little flower keyrings.
- Make bottle cap lip balms and fill them with Vaseline, coconut oil, or mix with an old lipstick to tint.
- Turn a water bottle into a votive candle holder with sand, rocks, and an LED candle.
Other ways to reuse plastic at home
- Save your to-go containers and use them to send leftovers home with family and friends.
- Turn plastic milk cartons into storage for pens and pencils.
- Reuse Ziplock bags whenever possible for traveling, storing dry goods, and keeping things organized.
- Use a panini press to melt plastic bottle tops and create new items such as lampshades, Christmas decorations, and a heart mobile.

Fusing plastic: a DIY method for creating plastic sandwich wraps
Plastic sandwich wraps are a fun and economical way to reduce waste. They are also a great gift idea for teachers, parents, or anyone starting a new job. The process of fusing plastic to make reusable sandwich wraps is quite simple. Here is a step-by-step guide:
Firstly, collect plastic bags and bottle tops. It is recommended to use food-safe plastic freezer bags, such as Ziploc bags, and ensure that the plastic is clean and dry before beginning the fusion process. Sort the plastic by colour, and cut the plastic bags into similar-sized squares. Bottle tops can be broken down into small bits using a sandwich press. Set the sandwich press to 180°C and place the bottle tops between two sheets of greaseproof paper. Weigh them down and squash them flat, then cut them into small shards with scissors.
Next, it's time to fuse the plastic. Place a sheet of greaseproof paper or parchment paper on your work surface. Layer several pieces of plastic on top, ensuring that the plastic pieces overlap slightly to create a larger sheet. Cover with another sheet of greaseproof or parchment paper. You can use an iron to apply heat and pressure to fuse the plastic pieces together. Ensure that the iron is set to a moderate temperature to avoid shrinking the plastic. Keep the iron in constant motion, applying even pressure across the surface. Check the plastic frequently to see if the pieces are fusing together.
Once the plastic has cooled, you can cut it into your desired shape. You can create a simple square wrap or experiment with different shapes. If you want to add a closure, such as plastic snaps, be sure to place them before sewing up the final side. Fold up the sides and sew them together to create an envelope-style sleeve.
There are endless possibilities for personalizing your sandwich wraps. You can cut out letters from plastic bags and fuse them between layers of plastic to create cute messages. You can also experiment with different colours and patterns to make your wraps unique and aesthetically pleasing.
It is important to note that there is some debate about the food safety of using plastic grocery bags for sandwich wraps. If you are concerned, it is recommended to use food-safe plastic bags, such as Ziploc bags, for the final layer that will come into direct contact with food.
By following these steps, you can create your own plastic sandwich wraps and contribute to reducing plastic waste. Enjoy experimenting with this DIY method and sharing your creations with others!

Plastic alternatives: using fabric and paper to reduce plastic waste
Plastic is a material that has become ubiquitous in modern life, from food packaging to household items. However, its negative environmental impact is well-known, with plastic pollution affecting our oceans, wildlife, and climate. Single-use plastics, in particular, are a significant contributor to this issue. To reduce plastic waste, individuals and industries are increasingly turning to fabric and paper alternatives.
Fabric alternatives to plastic offer a more sustainable and eco-friendly option. Natural fabrics, such as cotton, canvas, jute, hemp, and bamboo, are renewable resources that can be used for shopping bags, wine totes, and cutlery. These fabrics are durable, reusable, and biodegradable, reducing the amount of waste that ends up in landfills or incinerators. Additionally, natural fabrics are often free from the harmful chemicals found in some plastics, making them a healthier choice for both humans and the environment.
Some innovative fabric alternatives are also gaining traction. For example, cactus-based materials offer a more sustainable alternative to leather and synthetic fabrics, although they do undergo some chemical processing. Algae-based bioplastics are another emerging option, providing a bio-based and chemical-free alternative for packaging materials, disposable items, and even fashion accessories. These alternatives not only reduce plastic waste but also address the environmental impact associated with raw material extraction and hazardous chemical release.
Paper, too, is being favoured over plastic in certain applications. Paper bags, for instance, are more readily recyclable than plastic bags, although they do have a higher carbon footprint. Cardboard packaging is also becoming more common, with companies adopting plain cardboard boxes that are fully compostable. However, it is important to note that paper and cardboard may not be infinitely recyclable due to the shortening of fibres with each reuse.
Ultimately, the key to reducing plastic waste lies in reusability and refillability. Whether fabric or paper, alternatives that can be used repeatedly or refilled have a far lesser environmental impact than single-use plastics. Consumers can embrace reusable shopping bags, refillable glass or metal containers, and compostable cardboard packaging. By adopting these alternatives, we can collectively work towards reducing our dependence on single-use plastics and mitigating their harmful effects on the planet.
