streams. As such, peelable liners are named as the in- dustry preference, especially as they can help to re- duce food contamination. According to the guidelines, some film coatings added to packaging, such as single-sided laminates or metallicized films, do not interfere as much with the separation of fibre depending on the degree of adhe- sion, although the requirement to separate these can allegedly add costs. It does, however, warn that small metallic particles can interfere with the equipment used to measure flows in paper mills. Overall, FEFCO adds that — like plastics — it would prefer not to receive metallized or plastic laminated board. As for adhesives, the report suggests that the indus- try favors types that do not plasticize at temperatures above 35oC, which is the typical pulper temperature. The preference is therefore for cold set, curable, or wa- ter-soluble adhesives, rather than hot melt adhesives. When identifying their impact of varnishes on the recycling process, FEFCO says that UV varnishes can cause issues as they are not always removed by con- ventional de-inking technologies.Again, it reaches the verdict that these materials should be avoided. It does add that coatings that are soluble in water can gener- ally be treated in paper mills, so are acceptable for the industry. According to FEFCO’s report, fillers and binders — which are added to paper and board to provide en- hanced surface qualities and improve printability — do provide some challenges, but are normal constit- uents of the papermaking process, meaning they can be dealt with by paper mills. FEFCO further claims that most paper mills are set up to reprocess cellulose fibre derived from trees. It acknowledges that the industry is under pressure to develop alternatives to fibres derived from trees, but that these alternatives still require research to assess their suitability. Similarly, while FEFCO notes that the industry sup- ports research to develop alternative barrier technol- ogies, it says it cannot yet judge the recyclability of these technologies, partially due to Intellectual Prop- erty considerations. FEFCO concludes that it is not feasible or practical for the industry to evaluate the recyclability of indi- vidual packaging products on a case-by-case basis. Re- sponding to this challenge, it intends for the Corru- gated Packaging Recyclability Guidelines to provide design parameters that, if adhered to, can standardize and optimize the recyclability of paper-based packag- ing across the supply chain.
