layer of EVOH to achieve its aims. The product is aimed at the pet food packaging market. The chal- lenge for recyclable pet food packaging has been finding tech- nologies that maintain the efficiency of the packaging’s production and its final qualities – while relying only a single material. “Packaging recyclability is a challenge that no one company can do alone,” said Romain Cazenave, packaging EMEA marketing director at Dow Packaging & Specialty Plastics. “Dow’s Elite, Innate and Affinity resins and sealants have helped realise the next generation of recyclable packaging.” The film was produced on a W&H Varex II machine with inline MDO. It has a final web width of 2 x 1260 mm and is optimized to reduce material wastage during production. It was then laminated at industrial scale before being made into bags on B&B’s side-gusseted SFB bag ma- chine. This produced 80 bags per minute, which is comparable to multi-material PET/PE structures.
Mono-material pouch W&H – in collaboration with other partners – has also developed a mono-material PE pouch with similar properties to multi-material lami- nated pouches. The new pouches use the latest polymers, inks, coatings, adhesives and converting technology, say the partners – which also include ExxonMobil, Henkel, Kraus Folie and Siegwerk. The development allows for pouches with a high oxygen barrier,
package integrity and shelf-appeal. It produces an almost colourless recyclate after the removal of printing ink and the oxygen-barrier coating layer. To produce a colourless recyclate, the delamina- tion and removal of the printing ink and coating from the laminate structure is crucial. Here, Siegwerk’s delamination/deinking primer technol- ogy was applied on a W&H Miraflex II – a flexo printing press with a downstream unit. The oxygen-barrier properties are achieved through using Loctite Liofol BC 1582 RE – a
