barrier papers designed for performance and recyclability

Our paper scientists develop lightweight and flexible barrier papers for food and non-food packaging. Designed to deliver the required product protection and functionality, selected grades are optimized for horizontal and vertical form-fill-seal packaging applications. By combining low basis weights with fiber-based materials from renewable raw materials, we develop packaging papers that aim to use materials efficiently. Recyclability is evaluated at product level using recognized test methods, enabling customers to select the barrier performance and paper grade that fits their packaging application.

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 designed for performance and efficient material use

ultra-light

Using resources efficiently and not over-packaging goods – that’s the delfort way! Lightweight paper means less raw materials and less weight. That can result in less transport weight and less space required in storage.
high performing

Our 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 can be available with heat or cold sealability.
fit-for-purpose

Different 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^.
designed for recycling

Paper itself as a packaging material needs barriers to make it functional. We develop base papers and functional coatings together with recyclability in mind.
wood pulp from certified sources

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

For many years, we have developed high-performance grease-resistant papers for food applications. Our applicable grades are manufactured without intentionally added PFAS and meet the relevant regulatory requirements for their intended applications.

what our customers and partners say

Our partner delfort fills the gap in barrier papers and offers a solution with a water vapor barrier that performs reliably in use. The fortune cookies from Sweet & Lucky, packed in thinbarrier^® from delfort, demonstrate how functional paper packaging can be used successfully in the food industry.

barrier papers for flexible packaging designed by delfort and delsci

delfort and delsci have collaborate to drive packagin innovation

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 requirements. As examples, dry food may require 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 support the development of fibre-based packaging solutions by assessing recyclability and functional barrier performance.

Recyclability testing according to applicable test methods, including PTS-RH 021:2012, Aticelca 501:2019 and CEPI methodology
External recyclability/compostability testing by independent institutes such as ISEGA, TÜV Austria

Goal

Performance

regulatory

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