Legal Framework
Environmental regulations introduced by the European Union aim to reduce the volume of plastic waste in the environment by restricting specific disposable products. The single use plastics directive establishes the legal rules that force packaging manufacturers to replace plastic elements with fibre-based alternatives.
Substrate Shift
Under these rules, paper mills have had to develop water-resistant and grease-resistant coatings that do not use traditional synthetic polymer layers. Because the single use plastics directive restricts paperboard cups and food trays that contain a thin plastic lining, manufacturers must use bio-based coatings or water-dispersible barriers. These alternative layers allow the used packaging to be recycled alongside standard paperboard waste without requiring specialized separation plants.
Compliance Strategy
Paperboard converters must certify that their finished products comply with the strict definitions of plastic-free materials set by this law. If a product contains even a thin laminate layer of polyethylene, it must carry a warning label and is subject to higher producer fees under national schemes. Converting lines have adjusted their processes to apply aqueous-based dispersions, which are accepted as compliant because they dissolve during the paper recycling process.
This legal push has driven rapid innovation in sustainable barrier coatings, shifting the balance of materials used in fast-food and beverage packaging globally.
