Compostable ziplock bags can help reduce landfill waste and create precious soil or fertilizer. Biodegradable and compostable bags are also an eco-friendly alternative to standard plastic bags due to their ability to dissolve much more quickly.

Compostable Ziplock Bags | Buyer’s Guide

Pollution-conscious citizens are adapting to green products and a zero plastic lifestyle. In this pursuit, finding products that have minimal environmental impacts could be challenging. 

It is imperative to know the difference between biodegradable and compostable bags. After learning the difference, you’ll be able to discard them properly. There are designated places, such as compostable trash or landfill, where the product goes once discarded. 

The benefits of composting bags are endless. Plastic waste affects our lives in so many ways, from toxic chemicals constituting our air, water, and food supplies to leaving a hazardous scar on our planet. 

We want to make it super easy for people to adopt a green lifestyle. So below are some compostable bag recommendations to make your shopping experience as convenient as possible. 


Size is everything, despite what you heard. To avoid tears or wastage, get a bag that fits. A bag that’s too big is not efficient. A bag that is too small leads to rips and tears. Before you buy, take a look at the product description and dimensions.

Minigrip Greenline and Bisosafe ziplock bags have the most diversity and are available in many different size ranges. You can easily pick the size you need.


Some biodegradable and compostable bags are fragile, while some are tough. Keep in mind: they’re just like regular plastic bags but degradable.

They’re also great for the freezer. Use them in the freezer or pantry as many times as you like. And they’re not just made for food storage but also for trivial items. Use them to store and organize your office or home supplies. 

For the purposes listed above, you can’t go wrong with the Minigrip Greenline or Earth’s Natural Alternative bags.


There’s a common notion that environmentally safe items cost more than commercial options. A biodegradable bag does cost roughly 5x more than a standard bag, but the price balances out over time.
