Mission: Sustainability


We take responsibility for the environment

We are ready to make a comprehensive contribution to saving resources and protecting the natural world: by using less material, by optimizing the energy concept for our production process and by conserving finite raw materials.

As a manufacturer of plastic films, we take responsibility. We’ve proven this with more than 20 years of research and development work in the field. We started in 1998 with films which were 100% recyclable. Since 2002, we’ve offered a variety of eco-friendly films for load securement. In 2019, we introduced sustainable, bio-based polyethylene films (made using sugar cane) to our portfolio.

UN Global Compact

Since 2022 DUO PLAST has been committed to the UN Global Compact corporate responsibility initiative and its principles in the areas of human rights, labour, the environment, and anti-corruption.



International Sustainability & Carbon Certification

In 2021, we stopped using bio-based plastics made from sugar cane and switched to using tall oil as our raw material for manufacturing bio-polyethylene, the fundamental component of our films. Tall oil is a by-product/waste product of the paper manufacturing process. These films are ISCC PLUS-certified. This is the first officially recognized certification system for sustainability and reducing carbon dioxide emissions.

Here we are taking a stand against the expansion of monocultures and the increasing area used for monoculture in Brazil.

Pioneer in sustainable films since 1998

A recycling company officially listed by Valipac Belgium


  • Valipac is an independent organization that advocates extended producer responsibility for commercial and industrial packaging
  • They support their customers in the transition to a circular economy
  • One of Valipac’s initiatives is the “My recycled content” platform which aims to promote the use of commercial and industrial packaging made from recycled plastic

Here are our award-winning sustainable packaging solutions

  • Films for transport and pallet securement: either tall oil-based, or using recyclate from used films (PCR) or waste film cut-offs from the production process (PIR)
  • EVOH barrier films made from conventional PE – sustainable because it is 100% recyclable
  • Silage wrap with a high proportion of carefully collected and recycled films

This is our sustainability approach

  • Conserving raw materials: stretch wrap – as thick as necessary, as thin as possible
  • Reusing leftovers: packaging film using recyclate made out of waste film cut-offs from the production process
  • Promoting the circular economy: packaging film with recyclate made out of used film (PCR)
  • Conserving resources: stretch films using increasing amounts of tall oil instead of petroleum

Reduced material thickness conserves raw materials

We’ve always worked according to the motto: maximum safety and cost-effectiveness using a minimum of resources. So we are constantly improving our formulas in our own laboratory, to ensure our stretch wrap is as thin as possible but extremely resistant to tearing at the same time. This fully recyclable NEW GENERATION resource-optimized film is made from 100% conventional fossil-based polyethylene (PE), entirely without PIB (polyisobutylene) additives.

Resource-conserving sustainable films using leftover wrap

We are pioneers in the recycling economy. We have been using our own in-house regranulation equipment since the late 1990s to make the most of leftover film and film waste generated during production. We use the recyclate created by this process in our Post Industrial Recyclate (PIR) films. This eco-friendly packaging consists of up to 65% post industrial recyclate.

Eco-friendly stretch wrap using recycled plastic

Our films from the FootPrint series show it’s possible to manufacture sustainable films with a significant proportion of recycled material – without compromising on quality in terms of elasticity, resistance to tearing and puncture resistance. Our DUO EARTH 4 film with 30% Post Consumer Recyclate (PCR) was awarded the PackTheFuture Award  and the German Packaging Award in 2020, and the Worldstar Award in 2021. It is proof that excellent product properties and resource conservation can be combined successfully.

Tall oil-based biofilms

For our bio-based films, we use granulate made from natural resin acids and fatty acids (tall oil). This biological raw material occurs as a by-product during the manufacture of paper or pulp products. Tall oil is added to the traditional polyethylene manufacturing process in a fixed percentage during quantity balancing. We source our plastic granulate exclusively from ISCC Plus-certified manufacturers – and we ourselves are also ISCC Plus-certified for manufacturing sustainable bio-based films.

Unlike bio plastics made from renewable raw materials such as maize or sugar cane, no land (which could otherwise be used for food production) is needed for tall oil. What’s more, the burden on the environment due to transport is reduced, as tall oil can also be sourced in northern Europe. In contrast, plastic granulate made from sugar cane – which is often used for bio-based films – must travel long distances by ship from South America to Europe.

We focus on recyclability rather than biodegradability

Our conventional and sustainable films are 100% recyclable – a critical factor for truly eco-friendly packaging: which is not only characterized by its conservation of resources, but also by its reusability / recyclability. Whereas biodegradable films consume raw materials, we keep the valuable resources in the materials product cycle for as long as possible.

We make it easy to switch to bio-based films

With DUO PLAST’s eco-friendly films you can help conserve the planet’s finite petroleum resources while retaining the same high level of quality.

We’ll calculate your carbon footprint and look for potential savings

If you want to improve your carbon footprint too, then give us a call. Our innovative CO2 Tool enables us to calculate your personal carbon footprint and find potential for savings. We’ll check which sustainable film ideally matches your packaging requirements: films with a resource-conserving material thickness, with or without recyclate, or made using tall oil. We are also happy to find out whether the film you’ve used until now – perhaps with customized specifications – can be produced as a sustainable variant.

Our wish for the future: to replace petroleum with tall oil

Our vision is to gradually replace petroleum-based granulate with bio-based alternatives so that, at some point in the future, we will be able to offer our customers entirely sustainable stretch films. Until now, the proportion of bio-based raw materials for manufacturing granulate is comparatively small, meaning that tall oil is added during a certified quantity balancing procedure.

But the greater the demand for the sustainable alternative tall oil, the more tall oil the chemical industry will need to use for manufacturing plastics – and the more the proportion of petroleum-based plastic granulate will be reduced. However, for this to happen, the demand for tall oil-based films needs to grow. Just as for other organic products: demand creates the market – whether for films made from bio-based materials using renewable raw materials, recyclable films or biodegradable films.
