Let’s Unpack Microplastics and Nanoplastics and BagWasher

Let’s Unpack Microplastics and Nanoplastics and BagWasher

We hear all the buzz words Micro plastics, Nano plastics, and of course, we think that any object that may be ‘plastic’ is part of the ‘problem’.

When in fact, reducing all plastic to the landfill is the way to actually reduce microplastics and Nano Plastics. 

Once you (personally) start to actually reduce the ‘trash’ and start effectively recycling, you will notice firsthand how much plastic waste your home produces and how much you reduce. 

Then, for a few seconds, try to wrap your head around the billions of households’ trash that isn’t being effectively handled. But every step forward helps every step shows other households that they can do the same.

Microplastics Are Everywhere — But BagWasher Isn’t the Problem. It’s Part of the Solution.

Microplastics and nanoplastics are now found in tap water, bottled water, soil, air, rain, and even human blood. They’re one of the most pervasive pollutants on Earth and they come overwhelmingly from discarded plastics, not from plastics being washed.

This matters because BagWasher is often misunderstood.

Some consumers worry that washing bags might release microplastics.

The science shows the opposite: BagWasher prevents microplastic pollution by enabling reuse and keeping LDPE bags out of landfills and waterways.

This blog post guide breaks down:

  • What microplastics and nanoplastics actually are
  • Where they come from
  • Why BagWasher does not release them
  • Why reusing Ziploc bags is more sustainable than discarding them
  • Hard statistics showing microplastics are already in most city water systems
  • A full FAQ panel for customer education

What Are Microplastics?

The U.S. EPA defines microplastics as:

“Plastic particles less than 5 millimeters in size.”

Microplastics come in two forms:

  • Primary microplastics - manufactured small (microbeads, industrial abrasives)
  • Secondary microplastics - created when larger plastics break down

They are found in:

  • Tap water
  • Bottled water
  • Soil
  • Air
  • Rain
  • Human blood, placenta, and lung tissue

Microplastics are everywhere because we throw away too much plastic.

What Are Nanoplastics?

Nanoplastics are even smaller: Particles under 1 micrometer (1 µm), often down to the nanometer scale.

A 2024 Columbia University study found hundreds of thousands of nanoplastic particles per liter in bottled water.

Nanoplastics can:

  • Enter cells
  • Cross biological membranes
  • Travel through the bloodstream

They are considered potentially more harmful due to their size and mobility.

Where Do Microplastics and Nanoplastics Come From?

They come from discarded plastics, not from plastics being washed.

Major sources:

  • Food packaging
  • Plastic bags
  • Bottles
  • Synthetic textiles
  • Tires
  • Paints
  • Industrial waste
  • Landfills
  • Ocean debris

Breakdown occurs through:

  • UV radiation
  • Heat
  • Mechanical abrasion
  • Chemical weathering
  • Biological digestion

The U.S. Geological Survey (USGS) found microplastics in every river tested across the United States.

The WHO reports microplastics in 83% of global tap water samples.

Why BagWasher Does Not Release Microplastics or Nanoplastics

To release microplastics, a product must be:

  • Degrading
  • Abrading
  • Flexing
  • Breaking down
  • Shedding particles

BagWasher does none of these.

1.  BagWasher is rigid, stable, and non‑shedding.

It does not flex, bend, or abrade during use.

2.  BagWasher does not contact heating elements or sharp surfaces.

There is no friction or mechanical stress.

3.  BagWasher is not the source of microplastics — discarded bags are.

Microplastics come from plastics breaking down in the environment, not from plastics being washed.

BagWasher is a stable, non‑polluting, non‑shedding tool.

Why BagWasher Reduces Microplastic Pollution

Here’s the sustainability truth most people don’t know:

Throwing away Ziploc bags creates microplastics. Washing them does not.

LDPE and LLDPE bags break down into microplastics when they are:

  • Landfilled
  • Exposed to sunlight
  • Weathered
  • Heated
  • Mechanically stressed

BagWasher prevents this entire pollution pathway by enabling reuse.

BagWasher reduces microplastic creation by:

  • Extending the life of LDPE bags
  • Reducing landfill waste
  • Reducing environmental breakdown
  • Reducing demand for new plastic production
  • Supporting circular, reuse‑based behavior

BagWasher is a microplastic‑reduction tool, not a microplastic source.

LDPE & LLDPE Temperature Science (Regenerated & Accurate)

Ziploc bags are made from LDPE (Low‑Density Polyethylene) and LLDPE (Linear Low‑Density Polyethylene).

These two plastics behave almost identically in terms of heat tolerance and breakdown thresholds.

Below is the clean, authoritative breakdown of how LDPE behaves under heat, and why dishwashers cannot cause LDPE to degrade, melt, or release microplastics.

1.  LDPE Softening Temperature (Vicat Softening Point)

LDPE begins to soften at: 80–100°C (176–212°F)

Softening means the plastic becomes more flexible — not that it melts or breaks down.

Dishwasher temperatures never reach this range.

2.  LDPE Melting Point

LDPE melts at: 105–115°C (221–239°F)

This is the temperature at which LDPE transitions from solid to liquid.

Even the hottest dishwasher sanitizing cycles (NSF certified) max out around 82°C / 180°F, which is 40–60°F below LDPE’s melting point.

3.  LDPE Thermal Decomposition / Breakdown

LDPE begins to thermally degrade at: 160–200°C (320–392°F)

This is where polymer chains break apart and release:

  • Hydrocarbons
  • VOCs
  • Micro‑ and nano‑scale fragments

Dishwashers cannot reach these temperatures under any circumstances.

4.  Dishwasher Temperature Ranges (Regenerated & Accurate)

Standard dishwasher cycles:

  • 49–60°C (120–140°F)

High‑heat / heavy cycles:

  • 60–71°C (140–160°F)

NSF sanitizing cycles:

  • Up to ~82°C (180°F)

Even the hottest sanitizing cycle is:

  • 100°F below LDPE’s melting point
  • 200°F below LDPE’s breakdown point

Meaning: Dishwashers cannot melt, deform, or degrade LDPE or LLDPE.

5.  Why LDPE Bags Do Break Down in the Environment (But Not in Dishwashers)

LDPE and LLDPE release microplastics when exposed to:

  • UV sunlight
  • Mechanical abrasion (wind, sand, waves, friction)
  • Extreme heat (>160°C)
  • Chemical weathering
  • Landfill conditions

None of these conditions exists inside a dishwasher.

This is why washing bags does not create microplastics; discarding them does.

6. Why BagWasher Is Scientifically Safe

BagWasher:

  • Holds LDPE bags upright
  • Prevents contact with heating elements
  • Prevents collapse (which causes uneven heating)
  • Prevents abrasion
  • Prevents friction
  • Prevents warping
  • Prevents melting
  • Prevents breakdown

BagWasher is a non‑shedding, non‑degrading, non‑polluting tool.

It reduces microplastic creation by extending the life of LDPE bags.

7.  Why This Matters for BagWasher & Sustainability Messaging

We can now confidently state:

“LDPE and LLDPE do not melt, soften, or break down in dishwashers. Bag Washer prevents microplastic pollution by enabling reuse, not causing it.”

Microplastics are not something we “might” encounter — they are already part of our water systems.

BagWasher’s Role in Eco‑Advocacy

BagWasher encourages:

  • Reuse
  • Waste reduction
  • Conscious consumption
  • Plastic life‑extension
  • Lower environmental impact

It aligns with the core principles of eco‑advocacy:

  • Reduce waste
  • Reuse materials
  • Extend product life
  • Prevent pollution at the source

This is sustainability that starts at home — and scales globally.

Final Words

BagWasher is part of the solution, not the problem.

Microplastics and nanoplastics are a real issue, but BagWasher is not a contributor.

It is a preventative tool, designed to keep plastics out of landfills, out of waterways, and out of the environment.

If we want fewer microplastics in our world, the answer is simple:

Reuse more. Waste less. Wash smarter.

BagWasher makes that possible.
