BASF Solutions for the Entire Packaging Life Cycle

Increasing resource efficiency and the use of alternative feedstocks in  production. Providing additional benefits during the use phase. Enabling circularity at the end of service life.

Smart use of resources during production

In terms of production, the focus is on achieving process efficiency, product  effectiveness and reduced emissions through the use of alternative feedstocks.

BASF is planning to showcase products made from bio-based raw materials  obtained from responsible sources as well as products made from recycled plastic  waste.

The use of alternative feedstock helps conserve fossil fuels, reduces  greenhouse gas emissions and diversifies the product range.

In addition, the mass  balance approach ensures that more raw materials from organic waste and  vegetable oils or plastic waste are used within BASF’s Verbund production system.

Alternative feedstock is added at the very beginning of the Verbund production  system and then allocated to the respective sales products using an independently certified method.

The products are of the same quality and properties. Another showcased solution to reduce emissions are BASF’s water-based technologies.

As  an alternative to solvent-based technologies they improve occupational health and safety while reducing the CO2 footprint.

Added benefits during the use phase

During their use phase, packaging solutions have to ensure safe handling and reliably preserve the quality of the packaged goods.

BASF solutions provide added  benefits such as lower packaging weight, which reduces the amount of resources  used and packaging waste generated.

In addition, BASF materials maintain the  safety and extended shelf life of packaged goods, an important factor for sensitive  applications such as the packaging of fresh foods.

At the same time, this helps to  reduce food waste. 

Tackling the end-of-life-challenges of packaging

At the end of its service life, the most appropriate recovery option should be chosen to manage packaging waste to keep it from being sent to landfills or incineration facilities.

BASF will be exhibiting solutions for the chemical, mechanical and organic recycling of packaging products.

BASF’s project ChemCycling focuses on  chemical recycling to provide virgin-grade material based on recycled plastic waste,  allowing the high-value recovery also for plastics for which there are currently no  other recycling solutions or capacities are lacking.

In terms of mechanical recycling  solutions, BASF has developed special adhesives for flexible packaging that  facilitate the separation of multi-layer structures.

Furthermore, certified compostable  materials make organic waste easier to collect and to recycle in large quantities. 

This counteracts the inefficiency and the greenhouse gases emitted by other  disposal ways for organic waste.

At the same time, high-quality compost or organic  feedstock is produced that can be used for new products. 

New Ultradur® grades for thermoforming and injection-molding applications  with tailor-made property profiles

The world’s first thermoformable PBT Ultradur® B6560 M2 FC TF combines all the characteristics of the Ultradur family while additionally providing excellent oxygen,  water vapor and aroma barrier properties.

Polymer chains are branched through the  addition of special additives, creating a material with very high melt strength that  can be processed by extrusion.

The monomaterial product is thus the perfect choice  for the extrusion of films, the thermoforming of packaging as well as for high  temperature applications.

Its excellent processability was confirmed by ILLIG  Maschinenbau, a leading global supplier of thermoforming and mold systems for  thermoplastics.

Ultradur B6560 M2 FC TF offers good mechanical properties, is  easy to color and can even be used for foaming.

It allows the recirculation of the  processing waste into the production chain, thereby minimizing the total amount of  plastic waste generated during production. 

Ultradur B1520 FC R1 is a high-flowability PBT that was specially developed for  injection-molded packaging applications.

The material has been certified for food-  contact applications and can therefore be used for thin-walled packaging for  cosmetics and food products.

It is the product of choice for single-layer, aroma-  sealed packaging. Secondary packaging is made redundant by  Ultradur B1520 FC R1’s well-balanced barrier properties against moisture and  oxygen.

The packaging can also be very thin, which is a prerequisite for economic  and ecological production.

Therefore, Ultradur B1520 FC R1 means: less  resources, less packaging waste. 

Ultramid® Flex F38L: A partly bio-based copolyamide with outstanding  properties

Ultramid® Flex F38L is a partly bio-based copolyamide with outstanding properties that cannot be achieved by conventional polyamides.

Thanks to its softness and  transparency even at lower temperatures, Ultramid Flex F38L is ideally suited for  soft packaging, like soft vacuum and shrink bags.

During production,  Ultramid Flex F38L is soft without conditioning immediately after processing and  absorbs 50% less water than polyamide 6.

As its O2/CO2 transmission ratio differs  from that of other polyamides, this grade is ideally suited for manufacturing cheese  ripening bags.

Ultramid Flex F38L is one of BASF ́s contributions for the production of sustainable packaging.

Locally grown rapeseed oil makes up about one-third of  the raw materials used to produce the monomer. 

Ultramid® CcycledTM preC 3: Introducing a family of polyamide 6 extrusion  resins made from 100% recycled pre-consumer waste

In response to customer requests for a wider range of materials with recycled content, BASF is introducing polyamide 6 extrusion grades sourced from recycled  pre-consumer waste.

These materials are obtained from production and process  waste generated during the polyamide production at BASF and are broken down in  a separate process to the level of the monomers of polyamide 6.

This monomer can  replace virgin monomer, thereby saving primary fossil raw materials and reducing  CO2 emissions to levels below those emitted during incineration or landfilling.

The  mass balance approach is applied in the production of Ultramid® CcycledTM preC 3. 

This approach ensures that the recycling grade is of the same quality as that of  virgin materials.

The recycling materials are certified by an independent third-party  organization. 

Styropor®: Increasing recycled content with ChemCyclingTM products

With its ChemCycling project, BASF is taking an important step towards achieving a circular economy.

Plastic waste that is not recycled mechanically can be broken  down into its molecules and used as raw materials for sophisticated applications. 

During the pilot phase, Styropor® P CcycledTM was even used for transport boxes  for fresh fish, insulated packaging for temperature-sensitive pharmaceuticals and  protective packaging for electronic devices.

“These prototypes show that chemical  recycling is able to produce virgin-quality material and, at the same time, facilitates  the recycling of such materials as mixed plastic waste or other contaminated plastics  that cannot be recycled mechanically for technical or economic reasons.

Together  with mechanical recycling, chemical recycling can also help to close the materials  cycle and can contribute to increasing the number of high-performance products  based on recycled raw materials,”.

Certified compostable biopolymers for cling film and paper coatings

The certified compostable plastic ecovio® can now also be used to manufacture  cling films for the packaging of fresh foods.

BASF will be presenting the first certified compostable cling film that combines optimal breathability, which extends the shelf  life of fresh foods, with high transparency and excellent mechanical properties for  automatic packaging.

Meat, seafood as well as fruit and vegetables can be wrapped  manually or using automatic packaging equipment.

Industrial stretch packaging is  also possible. After usage, the cling film can be composted together with any food  waste either in home compost or industrial compost facilities according to national  legislation.

The cling film thus enables organic recycling and helps close the nutrient  loop to achieve a circular economy. 

The biopolymer ecovio can also be used for the coating of cups, plates and trays  made of paper, cardboard or recycled paper.

The grade ecovio PS 1606 is suited  for applications in contact with hot, cold or fatty foods because of its excellent barrier  properties. It is certified compostable in industrial composting facilities (EN 13432). 

Therefore, after consulting the local community waste management, the food  service articles can be composted together with leftover food as organic waste. 

Thus, ecovio facilitates and increases the collection and recycling of food waste at  public events. 

Flexible packaging solutions with water-based Epotal® adhesives

BASF’s water-based Epotal® lamination adhesives are a sustainable alternative to  solvent-based and solvent-less products.

They represent a reliable option for  manufacturers of flexible packaging on all performance levels.

Their high initial  bonding strength enables the immediate further processing of the laminates. 

Curing times are minimal, which means increased flexibility for the customer by  significantly shortening lead times and enabling in-line printing and lamination. 

Due to their chemical composition, water-based adhesives are inherently safe  systems and well suited for food packaging applications. 

The Epotal portfolio also tackles the end-of-life challenges for flexible packaging. 

Epotal adhesives facilitate the recycling of multi-layer packaging materials by  making the single layers of a packaging film easy to separate from each other within  the recycling process.

To achieve fully compostable packaging, Epotal Eco  adhesives can be combined with paper, BASF’s biopolymer ecovio or other  compostable polymers.

The Epotal BLX line provides the means to create barrier  coatings or adhesives for highly functional mono-material packaging, thereby  facilitating the recovery and reuse of materials from plastic waste. 

Solutions for packaging inks and barrier coatings with water-based Joncryl®  resins

BASF’s comprehensive resins portfolio meets even the most stringent formulation  requirements of ink, ink-receptive coating and overprint varnish manufacturers.

The  Joncryl® FLX portfolio has become established as the reference standard for resins  used in water-based film printing inks.

Combining excellent resistance and  lamination bond strength with high resolubility, the performance of these water-  based resins is similar to that of their solvent-based counterparts for printers and  converters of flexible packaging.

BASF’s Joncryl HSL product line offers a range of  options for heat seal lacquers for various applications, providing secure seal and  smooth peeling behavior.

The Joncryl MB portfolio was developed as part of BASF’s  biomass balance approach for water-based binders and helps to achieve significant  savings in CO2 emissions without having to compromise on quality or performance. 

BASF’s Joncryl HPB technology provides formulators with water-based polymers  that are used in coatings for recyclable functionalized paper and paper board  packaging solutions.

These solutions include the Joncryl HPB system for recyclable, repulpable coatings that not only offer the same level of water resistance and heat sealability properties as current polyethylene extrusion coating layers but have also  been approved for food contact.

In digital printing, the Joncryl DPS portfolio includes  a range of high-quality raw materials for water-based inkjet ink.
