launched at Innovia’s site in Plock, Poland. “The film is a high-gloss white coextruded OPP film with a very wide heat seal range,” said Piotr Piasny, general manager at Innovia Films in Plock. “We made some significant changes to our extrusion lines to be able to deliver this specific grade.” Its features include high puncture resistance – which is important to preserve the product and prevent food waste. The printability of the product helps to achieve superior graphic appeal, and the film provides an easy-to-open package. The films are largely unaffected by climatic conditions but should not be stored above 40°C. Under suitable storage conditions, the film can be stored for six months without risk of deterioration.


The company recently opened an innovation


Standing up At last year’s Plastic Pouches conference, organised by AMI, Daniele Borin, senior product manager for flexible packaging in the EU at Taghleef Industries, said that stand-up pouches are one example of a product that will need to be redesigned in light of the new PPWR regulations. “PPWR sets targets that impacts pouches in the


areas of reduction and recyclability,” he said. For instance, the law sets a 5% reduction in

packaging waste by 2030, rising to 10% by 2035 and 15% by 2040. There are also tough targets for recyclability of packaging, and the inclusion of recyclate.


He said that Taghleef’s heat-resistant film can help to meet design criteria through higher heat stability and reduced thermal shrinkage. In addition, its Extendo PP-based barrier structures deliver protection against oxygen and water vapour. In one example, a PET/PE structure with an LDPE zipper was replaced with an Extendo XTHR grade, TSU and a PP zipper – for a mono-material (PP) solution with a high barrier. Similarly, with Sipospack, it replaced a PET/Alu/PE structure – plus PP zipper – with a mono-PP solution that boasted a high barrier against oxygen, moisture and mineral oil – as well as odour protection. The pouch is used for applications such as dry broth, chocolate and vitamins. “Mono-material design is crucial to meet


recycling – both mechanical and chemical – and recycled content targets of PPWR,” said


Borin. “Functionality needs to be maintained to guarantee product protection and performance.”

centre at its San Giorgio di Nogaro site in Italy. The new facility is designed to encourage collaboration and speed up innovation. By locating the centre adjacent to production lines – including extrusion, metallisation and coating – Taghleef has integrated research and development with manufacturing. “This is a testament to our commitment to meeting the evolving needs of the market,” said Wolfgang Meyer, managing director of Taghleef Industries in Italy. In addition, it has developed a partially bio- based version of its Derprosa polypropylene laminating films. Its Derprosa BioBlue range includes 30% resin


that is derived from waste cooking oil. “With Derprosa BioBlue laminating films you can contribute to a lower use of fossil resources and a reduction in carbon footprint,” said the company. It adds that the films offer the same technical


characteristics and performance as the equivalent versions made from traditional fossil-based materials.
