barrier papers for packaging with the planet in mind

To minimize the use of non-renewable materials and support a circular economy, our paper scientists develop lightweight, recyclable and flexible barrier papers for food and non-food packaging. These innovative papers are designed to perform, are fit-for-purpose and are optimized for horizontal and vertical form-fill-seal packaging applications. By balancing functionality with waste reduction, we reinvent paper through innovations that reduce material use and prioritize renewable raw materials. Our barrier papers offer the required functionality and protection.

we continuously push the boundaries of barrier papers

food and non-food packaging papers

Different types of food and non-food products require unique packaging and barrier properties. For example, dry foods need moisture resistance, while chocolates demand high grease resistance. Other products may prioritize high transparency or extended shelf-life properties.

We specialize in providing tailored paper packaging solutions for a wide range of applications, including dry food, fast food, fresh food, dairy, chocolate confectionery, cookies, frozen food, as well as sanitary products, cosmetics, diapers, and feminine care.

our specialty barrier papers are responsible

ultra-light

¹Using resources efficiently and not over-packaging goods – that’s the delfort way! Lightweight paper means less raw materials and less weight. That means GHG savings in transport and less space required in storage.
responsible

²Our papers are designed with the circular economy in mind. They are made with renewable and responsible raw materials that are recyclable. We focus on resource-conserving and energy-efficient production to reduce our carbon footprint.
high performing

³Our barrier papers are fit for many food and non-food packaging. They can be tailored to be resistant to oxygen, water vapor, grease, flavors and/or mineral oil and is available with heat or cold sealability.
fit-for-purpose

⁴Different products have different requirements when it comes to food and non-food packaging – there is no one-fits-all solution! We work on a case-by-case basis with our clients to address their specific needs.
recyclable

Paper itself as a packaging material needs barriers to make it functional. We develop both base papers and functional coatings that work together and that allow the final product to be easily recycled.
renewable

We only work with wood pulp suppliers who are FSC™ (FSC-C109921) and/or PEFC (PEFC//06-33-163) certified. Additionally, are committed to Canopy’s Pack4Good initiative which ensures that no pulp comes from Ancient or Endangered forests.
PFAS-free

Let’s make PFAS forever gone! We offer high-performing, grease-resistant papers that are free from intentionally added PFAS.

what our customers and partners say

Our partner delfort fills the gap of barrier papers and offers them with a water vapor barrier which works perfectly in use. The fortune cookies from Sweet & Lucky, packed in thinbarrier^® solution from delfort, are a successful step in permanently establishing sustainable paper packaging in the food industry.

scaling up barrier paper packaging expertise

Our R&D experts innovate to balance the optimally protection of the contents, the right barrier function, shelf-life, product safety and processability on existing converting and packaging lines. At the same time, they are maintaining the excellent ecological profile of paper supporting recyclability and/or compostability.

barrier papers for flexible packaging designed by delfort and delsci

delfort and research partner delsci have partnered to drive change

Together with our R&D partner delsci we drive development projects forward with agile methods and rapid prototyping in a short time and quickly ramp up to large-scale production. To this end, we established a dedicated a state-of-the-art coating and testing laboratory, run by a team of 20+ ambitious chemists, paper and packaging engineers.

fast-track product development

our design principles

We approach new products from a holistic point of view – from idea to final product. It saves you valuable time and resources by identifying potential obstacles and solutions at an early stage. Our capability in our laboratory enables us to pre-test and verify all packaging requirements.

what we look at

our capabilities

barrier paper properties

Each type of food or non-food has different packaging and barrier property needs. As examples, dry food needs moisture-resistance, while chocolate needs high grease-resistance. For others high transparency or sufficient shelf-life properties are must haves.

barrier tests including Cobb test, oil test, KIT test, vapor, oxygen and MOSH/MOAH tests
rapid prototyping with reel-to-reel coaters
shelf-life testing with different products and shelf lifve test method development
nutritional services like microbiology analyses, active water testing and tasting panels with external, scientific partners

type of packaging

our capabilities

type of packaging

Our lightweight papers are ideal for pouches, flow packs and bags. Important factors are the flex crack resistance or dead-fold properties of the paper, as well as the type of packaging machine and process.

barrier measurements on flat sheets and on folded sheets to draw conclusions on the flex crack resistance (deadfold) of the coatings
creation of packaging mock-ups using our own packaging machine
reliable sealing performance testing with adhesives or under elevated temperatures with a heat seal

Goal

Performance

circularity

We drive the shift to a circular economy by creating recyclable packaging with functional barriers.

Recyclability testing according to the most common standards like PTS-RH 021:2012, Aticelca 501:2019 and the new CEPI method
External recyclability/compostability testing by independent institutes such as ISEGA, TÜV Austria

regulatory

Already in the product development process we check for regulatory hurdles and make sure that the final product complies to all regulatory requirements and law.
