Reusable Sandwich Bags – The Sustainable Alternative to Ziplock Bags

In the last few years the world has become more conscious of our impact on the environment, and many have made the choice to ditch single-use plastics. If you’re one of those people, then congratulations! You’re at the beginning of a journey that will help to preserve our beautiful planet. 

Plastic sandwich bags are a staple in most households and packed lunches, but they are having a devastating effect on the environment; it’s therefore time to consider using sustainable ziplock alternatives

This article outlines the environmental impact of plastic ziplock bags, and why switching to reusable sandwich bags is better for our planet as well as your wallet.

What’s the Problem with Ziplock Bags? 

They’re in most of our drawers at home and used everyday. Why would something so popular have so many negative implications?

Well, the main problem with ziplock bags is that they’re made from low-density polyethylene (LDPE), a very popular plastic that’s also used to make shopping bags and shampoo bottles.

Of course, there are benefits to using LDPE which is why it’s so widespread:

  • Very durable and difficult to break (tends to stretch instead)
  • Water-resistant
  • Impact resistant – when shampoo bottles fall in the shower, the LDPE means they won’t crack
  • Cheap – ziplock bags can be bought in large quantities for very low prices
  • Convenience – this is undeniable. It’s easy to just grab a ziplock bag out of the drawer, and throw it into the trash afterwards without a second thought.

However, the use of LDPE is slowly destroying the environment. Its durability means that it doesn’t break down in nature; in fact, the average plastic bag takes over 500 years to degrade. This means that, long after we’re gone, the evidence of our heavy plastic use will remain.

When a ziplock bag is sent to a landfill it does not biodegrade; rather, it undergoes a process known as photo-degradation. Rather than degrading entirely LDPE breaks down into micro-plastics, which can wreak havoc on our oceans in particular.

The Impact of Micro-Plastics

Micro-plastics are too small to be seen with the human eye. However, tiny marine creatures (such as phytoplankton) often mistake these particles for food. They will build up in the creature’s stomach to the point where they can no longer eat actual food, causing a slow death by starvation.

The harmful toxins from micro-plastics are then passed on to larger predators who eat these tiny aquatic creatures. Therefore, they have the potential to wreak havoc on the entire marine eco-system.

Worse still, we don’t know the extent to which micro-plastics can harm humans. In 2018, it was found that traces of micro-plastics existed within the human digestive tract, and they are also in our tap water and many of our foods. It is thought that micro-plastics have the potential to impact our hormones, brain development, and they may even contribute to some cancers.

Other Issues 

In addition to the damage that LDPE causes to our oceans, the methods of production and disposal are also harmful to our atmosphere. The production of polyethylene generates huge amounts of carbon dioxide, which is a major contributing factor to climate change. 

When it comes to disposal, the vast majority of LDPE products will not be recycled. They will either be sent to a landfill or incinerated, and the latter option also emits harmful gases into our atmosphere.

For the LDPE products that do end up being recycled, it is a very lengthy process that involves separating each separate type of plastic. A lot of people will find it easier to simply send it to landfill. Sadly, ziplock bags also tend to clog up the recycling machines at waste facilities, so it’s usually not feasible to put them in your curb-side recycling.

Ziplock bags are undeniably convenient but, with every one that’s used, we are contributing to micro-plastics and the emission of dangerous gases. If we do not cut down on our consumption of single-use plastic now, by 2050 our oceans will contain more micro-plastics than fish.

Why You Should Make the Switch

Environmental concerns aside, there are a number of benefits to investing in a sustainable alternative to ziplock bags. If you and your family routinely take a packed lunch to school/work, sustainable sandwich bags are an absolute must. 

They’re More Fit For Purpose

Simply put, ziplock bags have very little uses beyond storage. Reusable sandwich bags, on the other hand, are usually made with material such as beeswax or silicone. They are therefore often microwave-friendly. If you wish to, you can bring hot food to work and heat it right inside the bag!

They’re More Durable

LDPE is certainly a durable material, but it sadly does not protect from the peril of squashed sandwiches. 

Reusable alternatives are designed to last, and the sturdier material will protect your food much better. They are also often waterproof, a quality that standard ziplock bags generally don’t offer. This way, you can throw your sandwich directly into your purse with no fear that it will be flattened by your wallet and other belongings.

They are Cost-Effective

Like with other reusable products, there is a larger upfront cost for reusable sandwich bags. However, this is small in comparison to the cost of the approximately 500 ziplock bags used by American families each year.

They Can Be Multi-Purpose

When you’re not having packed lunches, reusable sandwich bags can be put to other purposes. Once they are cleaned they can be used to store makeup while traveling, to organize clutter and more.
