Where to Buy the Best Biodegradable Plastic Bags for Packaging

Shipping has become the primary mode of sales in recent years, with small and large businesses alike selling more through online venues than in-store purchases. As such, plastic waste from plastic shipping bags has sharply increased, and individuals and businesses have begun switching to sustainable alternatives to plastic packaging.

Biodegradable materials are a great alternative to plastic bags, with a variety of options, from bags for individuals who only ship items occasionally to businesses that ship constantly. We’ve compiled a list of the top picks for biodegradable plastic bags for packaging to help you decide which one is right for you.

Read on to learn how we chose our top picks for biodegradable packaging bags, or jump to our recommendations.

Choosing the Best Alternatives

We kept several criteria in mind when scouring the market for the best biodegradable plastic bags for packaging. All of the options we’ve chosen are made with 100% compostable materials and are produced through ethical, sustainable practices.

Alternative Materials

As plastic fills landfills and waterways across the world with harmful, non-biodegradable residue, it’s important to switch to a bag that will minimize waste. All of our top picks are made with material that is biodegradable at home or in industrial composting facilities.

Our compostable choices include options that are certified by the Biodegradable Products Institute (BPI), meaning they will biodegrade in a commercial facility without leaving behind harmful residue. Some of these bags can even be composted at home!

We chose biodegradable plastic bags made of:

  • PBAT – PBATs are oil-based plastics that fully break down in a matter of weeks without leaving behind harmful residues. Studies suggest that production processes of PBATs may reach negative net emissions by 2040, but until then this material is not a perfect substitute for traditional plastics. PBATs are derived from synthetic oils, so their production emits greenhouse gases – though far less than traditional plastics. However, the polymers that hold this material together are broken down by naturally-occuring enzymes, meaning PBATs can fully decompose in most natural conditions.
  • PLA plastic – This non-synthetic plastic is derived from plant matter like sugar cane or corn starch. The production process of this material is still fairly energy-intensive, requiring high amounts of water and land-use – as well as resulting in high amounts of GHG emissions – due to agricultural practices for corn and sugar cultivation. However, unlike other plastics, PLAs fully break down, making them an eco-friendly substitution for plastics that would otherwise fill landfills and waterways.


Shipping is expensive enough as is, so our top choices take affordability into account to ensure you’re not overspending on shipping materials.

Social Responsibility

Reducing plastic waste is important, but so is social responsibility. That’s why our top choices ensure ethical practices in all steps of the supply chain.


Plastic bags have been a popular choice for shipping for decades due to their durability. When looking for biodegradable alternatives, it’s important that the material is sturdy enough to reach its destination in one piece.

PBAT, also known as polybutylene adipate terephthalate, is a polymer that fully breaks down in about six weeks. It doesn’t require an industrial composting facility, so it will easily break down whether it’s placed in an at-home composter or if it makes its way into waterways, without leaving behind harmful residue.

KBOT specializes in biodegradable shipping material and offer a variety of compostable mailers. These bags can break down in any natural conditions, meaning bags don’t have to be sent to industrial facilities for disposal.

We have noticed, though, that these bags aren’t as sturdy as some traditional heavy-duty plastic mailers. If you’re shipping something with sharp edges, the bags may get torn.


  • KTOB offers a subscription-based discount for retailers that ship regularly.
  • Mailers come in a variety of sizes and colors, from sleek black to bright pink, to best fit your preferences.
  • KTOB offers a variety of mailers, with padded and non-padded, wraps, and even biodegradable cups and straws!


  • Some customers complain that these bags are easily torn in transit.
  • Most tapes don’t stick well to the materials, so torn bags may not be repairable.

2. Kipulu

  • Material: PBAT and cornstarch
  • Size: 6 x 10 inch, 8.5 x 12 inch
  • Current price: $24.92 for 25 bags ($1.00 per bag)

Kipulu bubble mailers are durable shipping bags that are made to be tear and puncture resistant. While Kipulu doesn’t have the same kind of variety as other biodegradable packaging bags, these are far more durable than most.


  • These bags are more durable than most other options.
  • Bags have a shelf life of 12 months, comparatively longer than other biodegradable bags.
  • Bags come in black, pink, red, and purple options.


  • Little variety in their bags, so if you regularly ship various products and sizes, this might not be the brand for you.
  • Slightly more expensive than other options.


PLA, or polylactic acid, is a biodegradable plastic made from plant sugars and resins. PLAs will decompose in an industrial facility or an at-home composter, depending on the composition of the PLA material. PLA plastic’s decomposition results in no harmful chemical residues and its production results in 75% less greenhouse gas emissions than synthetic plastics.

3. BeauVibe

  • Material: PBAT and PLA
  • Size: 10 x 13 inch
  • Current price: $18.99 for 50 bags ($0.38 per bag)
