Be innovative - be BOPE

Brückner Maschinenbau has developed mono-material packaging solutions to close
the life cycle of plastic packaging as requested by brand owners and legislations.
Besides the state-of- the-art materials BOPP and BOPET, a new opportunity is opening up with BOPE:

100% mono-material packaging – best recyclability – minimal impact on the environment.

A JOINT DEVELOPMENT

Lotte is developing and testing their latest HDPE raw materials on Brückner’s pilot lines. This material is designed with a focus on a biaxially oriented film production.

LG Chem BOPE HD (Lutene-H LO4904P) exhibits remarkable processability, outstanding mechanical properties and excellent optical properties. Leveraging these exceptional physical attributes of BOPE HD makes the transition to a circular economy possible - converters can produce Mono-PE pouches in accordance with their specific requirements. LG Chem is currently also developing a BOPE LLD grade with excellent toughness and high puncture performance for frozen foods. With extensive experience gained through collaboration with Brückner, our passionate BOPE experts are ready to assist to guide you toward success.

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.

A true circular economy can only be realized if all partners work together along the value chain. This is why Henkel and Brückner are proud to work together on the development of functional coatings for flexible films with circularity in mind. We are focusing our joint efforts on improving both the heat resistance and barrier performance of oriented polyethylene structures while ensuring the highest level of performance and the best fit with industry processes. Because we believe sustainability and efficiency should be a both and – not an either or. The coated films are tested rigorously also in downstream processes, including laminating and packaging simulations.

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.

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 Consumer Flexibles (CFlex) is a global market leader of flexible packaging solutions. Their products not only protect what’s inside, but make it easy, safe and sustainable to use. Mondi CFlex’s commitment to a more sustainable planet include cutting-edge solutions that are recyclable, reduce material consumption, waste and CO2 footprint. Mondi CFlex has partnered with Brückner to develop a new range of BOPE films that are sustainable by design and fit for purpose. The new film grades will have defined film properties and high converting efficiencies. 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.
