We are aware of our responsibility
Because we care!
One of our main concerns is to leave the best possible world to future generations. All Brückner Group members are therefore working on ways to ensure that film and packaging are produced on their machines with the least possible use of resources and with the highest possible recycling capability.
The plastic films and plastic packaging produced on lines of the Brückner Group companies protect the packaged products against environmental influences. This extends the shelf life and reduces storage losses – good for the environment.
Brückner Maschinenbau and the whole Brückner Group are aware of their responsibility with regard to the environment and sustainability. That is why the initiative "Yes, we care" was launched in 2017. Environmental protection starts in our own company!
Sustainability is important to us
We participate in different initiatives and take care about sustainable film production and plastics processing
A JOINT DEVELOPMENT
From bilateral teamwork with raw material suppliers, masterbatch specialists, film producers and converters to more complex co-operations along the value chain: Brückner is involved at many levels. Thus, the best possible PE raw material for the biaxial stretching process with optimal film properties has been developed. The results have been transferred from the laboratory scale to production lines by upscaling and finalized in the BOPE/BOPP hybrid line layout.
Dow and Brückner are working together to develop linear low and high density biaxially oriented polyethylene (LLD-BOPE, HD-BOPE) as well as barrier solutions for BOPE. All three applications have been tested at Brückner, using the laboratory stretcher KARO 5.0 as film development and pilot line, and successfully transferred to a production line.
The collaboration between Brückner and LyondellBasell targets the development of advanced solutions for mono-material packaging based on HDPE products and a variety of masterbatches for BOPE films.
These BOPE films will be used for laminated mono material structures for flexible packaging to improve functionality and recyclability.
LyondellBasell (NYSE: LYB) is one of the largest plastics, chemicals and refining companies in the world. LyondellBasell sells products into more than 100 countries and is the world’s largest producer of polymer compounds and the largest licensor of polyolefin technologies.
ADMERTM and TAKELAC™ by Mitsui Chemicals
Inline Coating (ILC) is THE answer to BOPE film manufacturers for circular economy.
The alliance of innovative filming, metallizing and high-performing water-oxygen barrier allows the production of low cost recyclable films.
Our barrier solution will help to realize transparent designs in flexible packaging while extending the shelf life of food.
BOPE-HD is a transformative technology that is ideal for use in food packaging, heavy duty sacks, e-commerce and other demanding applications. NOVA Chemicals developed the first HDPE resin technology specially for the Tenter Frame bi-ax film process. This resin enables the manufacturing of all-polyethylene recyclable multilayer films with the physical performance of biaxial orientation. In addition to BOPE-HD, NOVA Chemicals also offers BOPE-LLD grades.
To bring BOPE-HD films to market, close collaboration between Brückner and NOVA Chemicals on resin and film structure designs as well as process conditions was required. A joint project with NOVA Chemicals, Brückner, and bi-ax film producer Polivouga resulted in an all-PE stand up pouch consisting of a stiff BOPE-HD print web.
Brückner and SABIC already collaborate for a long time to create sustainable solutions for the packaging industry. One solution that has been jointly developed and presented during the K-show in 2019 is a TF-BOPE film based on SABIC's LLDPE BX202, and new solutions are currently under development together.
During the latest cooperation, Brückner successfully tested SABIC® certified circular PP polymers certified derived from used plastic, part of the TRUCIRCLE™ portfolio, as a direct drop-in solution for biax-film applications.
Concerned about sustainable development, Ampacet saw in the emerging BOPE film technology and applications an opportunity to collaborate with brand-owners and packaging manufacturers on improved mono-material packaging designs for a Circular Economy. With the support of Brückner and the access to the BOPE pilot line, Ampacet developed and validated Biax4CETM portfolio of masterbatches dedicated to the bi-oriented polyethylene film process and end-uses. BIAX4CETM product range makes part of Ampacet sustainability program representing the company global commitment to sustainable development.
CONSTAB® Polyolefin Additives GmbH, member of Kafrit Group, is a globally leading producer of masterbatches and compounds for the plastics industry, with a focus on sustainable BOPP and BOPE applications.
By continuous collaboration with Brückner and its partners throughout the supply chain, CONSTAB® has established itself as the pioneer in BOPE-related masterbatch technologies. Both, the product expertise and service quality, constitute CONSTAB® as a preferred partner in developing new and innovative BOPE-film applications.
Tosaf is currently launching a portfolio of BOPE masterbatches that includes slip, antiblock, antistatic, antifog, matte and white. Tosaf did successful run trails, conducted at Brückner, to validate the processability of its new BOPE MBs, and have provided Tosaf's R&D team with the confidence that they meet all optical and functional properties – with no interference with mechanical properties whatsoever. Tosaf has simulated the production of BOPE films, using one of the most professional production lines currently in the market. This simulation serves as a further indication that Tosaf's new masterbatches are qualified for BOPE applications. Furthermore, these additives' suitability for bi-oriented production lines will ensure their suitability for in-line blown MDO films, which show signs of becoming yet another important future production trend.
Recyclability within a circular economy is the future of flexible food packaging. Polyethylene is the most widely used and adaptive plastic for all applications. Due to the cooperation of main resin producers (such as Sabic , DOW , Nova , LYB) with the leading film stretching line supplier Brückner Maschinenbau, polyethylene is presently going to be available in the bi-oriented form BOPE. Plastchim-T and Ticinoplast are working together under a long-term industrial agreement and have joined their forces with resin producers and Brückner to design and produce BOPE films. The common goal is to match the requirements of the converting and packaging machine manufacturers and to offer sustainable packaging solutions to brand owners. The new packaging structures – either monolayer or multiple laminated layers – shall provide good printability and sealability, excellent optical and mechanical properties, OTR and WVTR barrier properties (through primerizing and coating), anti-fog and anti-UV properties and much more.
Brückner is our key partner on the development of Helix® BOPE film product range, with their full support, we have been able to develop a portfolio of solutions to achieve a full Polyethylene mono-material structure, when different substrates mechanical properties are required.
Helix® BOPE film LLDPE and HDPE based grades, offer supreme high stiffness, high transparency, low haze and unique tear properties.
Polivouga is a flexible packaging converter group, who offers primary, secondary, and tertiary flexible packaging for an extensive range of applications in industrial, agricultural, retail and food flexible packaging.
COATING & ADDITIVES
The cooperation between the two companies is about functionalizing the newly developed BOPE film aiming to allow the easy transition from multi-material into a mono-material packages to focus on sustainability.
To achieve this we have improved the recyclability, by overcoming some mechanical, thermal and barrier limitation of polyolefin material vs actual plastic substrates used as primary web in multi-material package.
Constantia Flexibles, vastly recognized for converting and development of disruptive Ecolam technology (high barrier, machine direction oriented-PE laminates), is supporting Brückner on the development and converting of BOPE films. For this Constantia Flexibles and SN Maschinenbau as leading FFS-machine manufacturer utilize latest innovations from BOPE-technology for generating and testing form-fill-seal pouches on basis of mono PE-laminates. Combining biax technology, film, machine and converting know-how enables the transformation of multi-layer pouches into more sustainable, mechanically recyclable PE-solutions, but maintaining complete functionality and convenience of packaging.

Mondi CFlex will utilize their different print and converting technologies in their technology centre as well as various industrial converting plants. The ultimate goal of this collaboration is to replace all current multi-material combinations with recyclable mono-material solutions that support a circular economy.
Brückner teamed up with ppg > to process the BOPE laminate on their printing and lamination facilities. At an early stage of prototype manufacturing flexible production adjustments are always recuired to secure a proper outcome. The practical aproach of both project partners not only came up with a good result but also brought up some insights for further improved conditions of better BOPE converting. Enabeling this the cooperation took a step towards increased ammounts of recyclable PE-based materials for fmcg markets. ppg > strongly invests in practical solutions for enhanced sustainable flexible packaging regarding design for recycling as well as bio-based and recycled materials. So the converter provides customers with apporaches for a circular economy as well as a reduced carbon footprint.

Sustainable film production
Sustainability in film production has been our priority since the earliest days
We help to preserve nature and resources
The preservation of nature by using resources and products responsibly is becoming increasingly important. Since the company’s earliest days Brückner has given great thought of these vital issues.
Despite all necessary developments for the rapidly developing circular economy, Brückner Maschinenbau is keeping to its own ambitious objectives for a decreasing raw material usage and an increasingly minimal energy consumption during film production. Despite all legitimate demands about recycling and reusability, the challenge of climate change and the reduction of the carbon footprint throughout the entire packaging production chain must not be forgotten.
Today we have already achieved more than 42% reduction of the energy consumption for our film stretching lines and we are striving to reach a reduction of 50% compared to levels in 2000. We are well on our way to achieving our goal by:
- Heat recovery system - also available as an upgrade on existing lines
- Twin screw extrusion eliminating the necessity of energy-intensive raw material pre-drying
- Special energy monitor: permanent information about consumption show energy saving potentials
Sustainability also implies the use of renewable raw materials, the reduction of the raw materials used, a decrease in the number of process steps and the avoidance of waste. In the fight against climate change, we will still need plastic packaging that is produced in a resource-saving way. Brückner has contributet to this over the years through:
- R&D with bio-plastics, resulting in complete new lines as well as modifying existing lines for, e.g. BOPLA film production
- Downgauging of films while still achieving excellent film performance - less raw material usage
- Barrier films allowing packaging laminate simplification and reducing the number of further converting steps
Membership in sustainability initiatives
Our commitment to a world worth living in for future generations
In March 2019 a value chain project initiative was launched by a group of companies under the acronym PRINTCYC (Printed PP films for mechanical recycling) to research and test ways to create circular economy solutions basing on post-industrial waste. Members of PRINTCYC: The machine suppliers Brückner Maschinenbau, Kiefel and PackSys Global, the film producer Profol, the ink manufacturers Huber Group and Siegwerk, the converters Constantia Flexibles and Wipak as well as the recycling specialist Erema.
The initiative is coordinated by akk innovation, an independent start-up company for sustainable innovation management in the plastics packaging industry. The specific target of the first two project phases was to understand the impact of different ink formulations on the mechanical PP and PE recycling process. Furthermore, the re-usability of PP and PE recyclates (rPP / rPE) made from printed post-industrial film waste was evaluated in cast film, blown film, compression moulding and thermoforming technologies as well as the biaxial stretching process. Now the team is contacting new, prospective value chain partners and other recycling initiatives for designing the next working package to contribute to a circular economy of printed PP and PE films.
A circular economy for flexible packaging
Driving towards circular economy
And we are part of it
We see it as our duty to help to preserve precious resources. This is why we are a member of a collaborative project of a European consortium of companies and associations representing the entire value chain of flexible packaging called CEFLEX.
The mission of the project is to make flexible packaging more relevant to the circular economy. This should be achieved by advancing better system design solutions via the collaboration of companies representing the entire value chain.
- By 2020 flexible packaging should be recycled in most European countries.
- By 2025 a collection, sorting and reprocessing infrastructure/economy developed for post-consumer flexible packaging across Europe will be established.
Blue Competence establishes network links for the mechanical engineering industry in the area of sustainability and pools the resources, know-how and strengths of the German Engineering Federation (VDMA), the largest engineering industry network in Europe.
Blue Competence – these are the technologies and processes of mechanical and plant engineering which, for example, consume a minimum amount of energy while delivering maximum productivity, preserve our resources, reduce emissions to a minimum or improve people's living conditions in a sustainable way.
Every VDMA member company can participate in the Blue Competence initiative after signing the Blue Competence contract and the associated obligation to publish the twelve sustainability guidelines of the machinery and plant engineering industry on the internet.
How Blue Competence makes the world more sustainable
The participating companies publish their individual articles and solutions regarding the key questions of our time, accompanied and supported by the communication measures of the overall and professional associations. For this purpose, Blue Competence defines well-founded sustainability criteria and standards which all companies participating in the initiative endorse. The initiative thus ensures greater transparency, simplifies orientation and provides security to all those seeking sustainable solutions and products or companies operating sustainably.
On www.bluecompetence.net the VDMA publishes detailed information on the participating professional associations and companies, as well as „best-practice examples“, standpoints and positions which are significant for the implementation of sustainable business, ecological and societal solutions.
R-Cycle is the open and globally usable tracing standard along the life cycle of plastic packaging. The overall goal is to implement a practical solution, ensuring recyclability by seamless documentation of all recycling-relevant packaging properties based on established technologies. In the recycling process, packaging can thus be precisely identified in order to process the resulting recyclate into diverse and high-quality plastic products.
In collaboration with packaging manufacturers, brand owners, wholesalers, and retailers global identification numbers should be introduced and IoT gateways, the necessary server infrastructure and standardized formats for secure data exchange will be developed. Partners in this project are: Arburg, Kautex Maschinenbau, Reifenhäuser, Brückner Maschinenbau, EREMA, Kampf Schneid- und Wickeltechnik, MULTIVAC, STEINERT, the Institute for Plastics Processing (IKV) and GS1 Germany.
