A: Inverform is a fibre-based material with a low carbon footprint for replacing plastic and aluminium trays in food packaging applications. It consists of paperboard that is building the structure of the package and normally comes with a functional barrier for keeping foodstuff fresh and not influenced by outside environments.

A: Because it has the functional properties required and reduces the carbon footprint of the total package. By using Inverform, which is renewable and recyclable, and combined with a small amount of plastic material for the functional barrier, you create an eco-friendly package that can reduce the carbon footprint by 60 to 80 percent compared to a fully plastic solution. Several studies also show that consumers tend to prefer paperboard packaging from sustainability and aesthetics standpoints.
A: There is no aligned definition of biodegradability in the packaging world. And in the lack of proper definitions anyone can claim anything. An old plastic boat can be considered biodegradable – but the process of breaking down the hull might take 30 000 years. So be careful whenever biodegradability is claimed. Inverform is intrinsically biodegradable due to being fibre based, but depending on which barrier it is combined with, the degradation properties can vary.
A: There are established certifications for compostability. The common one, e.g. EN , stipulates that the material should be broken down within a specified timeframe in an industrial compost. All compostable materials are biodegradable, however not all biodegradable materials are compostable. Inverform is compostable but depending on which barrier it is combined with the degradation properties can vary.
A: Today, many recycling mills can separate plastic barriers from the paper or paperboard. The rules for sorting packaging with plastic barriers vary from region to region and depend on how developed the waste streams and recycling schemes are. In the UK recommended that packaging with as much as 15 percent plastic content can be sorted as paper. The UK recommendation is based on the condition that the allowed plastic content gradually will be reduced.
A: The main part of the tray is a paperboard made of wood fibres, a renewable material from well managed forests which can be recycled several times. In order to protect the content and to be sealable, the paperboard needs to be coated with a functional barrier. That coating can be either renewable or fossil-based and depending on the recycling infrastructure in your region, the fibres in the paperboard can then be recycled and reused.
A: Barrier coatings improves the properties of the paperboard and depending on which barriers you use, protect against grease, moisture, gas, aromas and UV-light. Barriers also provides the important sealing ability.
Appearance, feel, and functionality are some of primary reasons a package ends up in a shopping cart more often than another. It is not just a question of taste, but a skillful interplay of diverse components. At Henkel, we know what gives packaging the right shelf appeal – whether it has a matte or high-gloss surface, is resealable, offers anti-fog properties, safeguards flavor or provides barrier protection. Our flexible packaging coating solutions enable you to create that decisive difference. Whether you are looking for food contact coatings or primers for flexible paper packaging, we have the right material solutions for you.
Our flexible packaging coatings protect package content, consumers, and the environment. Heat seal coatings for lidding films help safeguard protected atmospheres and prolong storage life. Oxygen barriers for stand-up pouches that guarantee an extended shelf life. Last but not least, cold seal coatings for highest safety of chocolate bars. Furthermore, our barrier coatings for flexible packaging offer designers new creative options in packaging design – for example by integrating larger windows. It’s smarter to play it safe with Henkel's LOCTITE® LIOFOL food safe packaging solutions.

LOCTITE® LIOFOL functional coatings are solvent-based and help deliver excellent performance for many films while maintaining the highest clarity. They are primarily used for lidding and flow pack for both hot and cold products and are suitable for PE, PP, and PET. They are functional at very low coating weight, have outstanding performance for many different films such as OPP, PE, BOPET, and also have the highest clarity under a wide range of temperatures – even at elevated humidity levels, i.e. for fish and meat. Additionally, UV properties allow you to easily control the homogeneous application on the film using UV lights.
Do you want to achieve strong seals and easy peel at the same time? Go for Henkel’s heat seal coatings LOCTITE® LIOFOL heat seal coatings. To make sure you have a clearer view, our anti-fog heat seal coatings prevent condensation forming on transparent lidding films. At the same time, consistent packaging integrity and outstanding seal adhesion are maintained. What is more, these coatings replace the polyethylene layer. And, they are environmentally compatible as well as recyclable – this way you save materials and reduce waste. They are also in compliance with EU and US food contact regulation.
These heat seal coatings are solvent-based, are smooth peel at low coating weight as well as have low activation temperature, providing optimal seals with a low degree of haze. Our heat seal coatings also enable lightweighting for lighter packaging & lower thickness. Heat seal adhesive coatings are particularly suitable for polyester lidding films that are sealed to CPET, APET and RPET tray stocks. Suitable for BOPET lidding film to replace PP or PET/PE for fresh food and ready meal food packs – as well for microwavable and ovenable applications. For peelable lidding film with easy-opening properties without film breaks and use of tools.
Want to raise performance and profit? Our cold seal coatings and adhesives can be processed at high speeds without becoming stringy. At the same time, they retain excellent packaging integrity and are highly peelable. This makes them ideal for sealing chocolate or cereal bars, dishwasher tabs or noodle cups. Our coat seal coatings are compliant with EU and FDA food contact regulations and free of acrylamide.
Our cold seal coatings come in both water-based latex and synthetic chemistries with latex-free (synthetic) cold seals available soon to meet any application requirement. These cold seal coatings have aggressive and high seal strength bonds, are suitable for use on a number of films used in mono-web and laminate flow packaging as well as provide excellent unwind in laminate and monoweb structures. These coatings come press ready and easy to use cold seal with low foaming and good machine ability with easy processing at high printing speeds. Optimize your production and increase your efficiency – with our innovative flexible packaging coating solutions.
Our barrier coatings for flexible packaging help keep your food fresh. Do you want to benefit from the synergy of metallizing technology and a multifunctional coating for high barrier films?
