Our society uses
a lot of stretch film

Due to the globalized nature of our economy, stretch film is one of the largest uses of polyethylene in the world. With no real alternatives, essentially every pallet in the world is wrapped in this protective packaging.

100% of stretch film is made from plastic

Collectively, we manufacture nearly 2.5 billion lbs of stretch film each year. This means we're using enough stretch film to wrap around the earth 10 times... every single day.

Almost 95% of all stretch film is tossed

As it's such a massive industry, one would hope that we are recycling this product as much as possible. Unfortunately, this is not the case, with only an estimated 5% of all stretch film being recycled worldwide.

Sustainability is
no longer optional

We can't continue to ignore the impact that we're having on the environment.

It's time we take a good, hard look at the products that drive our economy and ensure they will not harm the planet and its inhabitants for generations to come.

Recyclable stretch film that bio-assimilates like paper

First and foremost, this stretch film is 100% recyclable and purposely designed for the circular economy. However, if it evades the recycling system, SPTek ECLIPSE™ Stretch Film will completely bio-assimilate in marine, terrestrial and all landfill environments within 6–24 months, resulting in zero microplastics.

What is
bio-assimilation?

Definitively, "bio-assimilation" means that the stretch film has degraded to a molecular weight that can be consumed by microorganisms, resulting in nothing more than CO2, water and biomass.

A molecular transformation

The bio-assimilation process takes place at a molecular level, breaking the carbon-to-carbon bonds within the polymer. It's critical to understand that this process does not result in microplastics.

Fuel source for microorganisms

With a tremendous amount of competition in the natural world, microorganisms clamber for the opportunity to utilize this newly available carbon as a fuel source.

Absolutely no microplastics

As this unstoppable process continues, all of the carbon within the stretch film is exposed and consumed, leaving behind nothing more than water, CO₂ and biomass.

Frequently Asked Questions

What is the purpose of SPTek ECLIPSE™?

ECLIPSE™ is our flagship technology that mitigates the environmental impact of plastic waste, without impacting recyclability. ECLIPSE™ acts as a crucial safety net in case plastic products evade the recycling system, ensuring they do not persist in the environment for generations. This technology is a critical part of the solution to global plastic waste.

Should I throw out an ECLIPSE™ enabled product?

First and foremost, all ECLIPSE™ enabled products are designed to be recycled. ECLIPSE™ technology is a critical safety net should products evade the recycling system, not an excuse to incorrectly dispose of plastic.

What is bio-assimilation?

Bio-assimilation is the final and conclusive stage of biodegradation where microorganisms can convert the material into CO2, water, and biomass.

How does ECLIPSE™ bio-assimilation work?

ECLIPSE bio-assimilation technology causes the complete molecular transformation of plastic. In other words, it breaks the carbon-to-carbon bonds within the polymer molecules, allowing microorganisms to feed on the available carbon. Once this process is initiated, it becomes a runaway freight train that can't be stopped, resulting in zero microplastics.

Here’s a step-by-step explanation of what happens during the bio-assimilation process.

  • At the end of an ECLIPSE™ enabled product’s functional life, the molecular structure of the polymer within the material has a molecular mass of approximately 200,000 Daltons.
  • ‍Stage 1 (200,000 Da): The free radical process begins and carbon-to-carbon bonds within the material begin to break. The molecular mass of the material rapidly reduces as the long-chain molecular structure transforms into shorter and shorter chains.
  • Stage 2 (40,000 Da): As the molecular transformation continues, these shorter chain molecular structures change from being hydrophobic (repelling water) to being hydrophilic (attracting water), surrounding them with microorganism-rich water (known as a bio-film).
  • Stage 3 (5,000 Da): As the free radical process continues to transform the molecular structure and expose more and more carbon, the surrounding microorganisms begin to utilize this carbon as nutrients.
  • Stage 4 (0 Da): As the microorganisms consume all of the available carbon, the molecular mass of the original polymer continues to reduce until there is nothing left but water, C0₂ and biomass.
At the end of the bio-assimilation process, what is left over?

CO2, water and biomass. No microplastics are left behind.

Can you recycle ECLIPSE™ enabled products?

Yes! First and foremost, ECLIPSE™ enabled products are designed to be recycled. The addition of ECLIPSE™ technology does not negatively impact the recyclability of the products or the recycle stream, provided the plastic has been collected and recycled before the bio-assimilation process has begun. If the material still has the mechanical characteristics of its original product, it can be recycled. The addition of ECLIPSE technology acts as a safety net in the event that the item evades the recycling system. It is not meant to encourage disposal in landfill.

Does SPTek ECLIPSE™ affect the traditional properties of stretch film?

ECLIPSE™ Stretch Film has gone through rigorous efficacy and performance testing which determined that it performs exactly like original products. The addition of SPTek ECLIPSE™ technology does not alter the benefits of conventional stretch film.

How do we know that the bio-assimilation claims are true?

We have conclusively proven our ECLIPSE™ bio-assimilation technology through rigorous independent third-party testing and a world’s first C-13 bio-assimilation study conducted at LMPE, a leading Ecosustainable Polymeric Material Laboratory located in Italy. ECLIPSE™ technology is also compliant with recognized ASTM standards.

Is SPTek ECLIPSE™ Stretch Film more expensive than conventional stretch film?

There is a low inclusion rate of ECLIPSE™ at only 1%, which adds a minimal cost to the overall price. To determine the optimal amount of film for each customer’s unique need, the Rite-Gauging Assessment is used. This assessment ensures customers aren’t paying extra for any material they will not use.

Is ECLIPSE™ Stretch Film available in hand and machine formats?

ECLIPSE Stretch Film is available in both hand and machine formats in a number of different gauges. Learn more about SPTek ECLIPSE Stretch Film here.

How long does it take for ECLIPSE Stretch film to bio-assimilate?

Following its guaranteed functional life span of 2-years, if ECLIPSE™ Stretch Film evades the recycling system, it will bio-assimilate in 6-24 months depending on environmental conditions.

Where will SPTek ECLIPSE™ products bio-assimilate?

ECLIPSE™ enabled material will bio-assimilate in marine, terrestrial, and landfill environments. However, the inclusion of ECLIPSE™ is not designed to promote the improper disposal of plastic products. ECLIPSE™ enabled products should always be recycled whenever possible.

Are ECLIPSE™ products compostable?

Will they compost, yes? ECLIPSE™ enabled material will decompose in a composting environment. However, ECLIPSE™ enabled materials are not ASTM D6400 compliant, due to the nature of the bio-assimilation process. With ECLIPSE, the vast majority of carbon in bio-assimilated material is sequestered as biomass whereas ASTM D6400 requires the majority of carbon within the material to be turned into CO2.
