UPM Specialty Papers continues to work with partners across the food packaging value network, co-creating innovative products that help to shape the future of sustainable packaging. A recent project undertaken with Unipaco S.A., a Polish converter in flexible packaging materials, has now resulted in a recyclable, heat sealable salad and herb pot wrapper that guarantees product safety. The structure also meets strict German 95\/5 mono-material requirements, with single-component materials accounting for 95% of the packaging mass.<\/p>\n\n\n\n
Growing demand<\/strong><\/p>\n\n\n\n Brands worldwide are setting increasingly ambitious sustainability targets, especially in terms of recyclability. At the same time, global regulations are becoming ever more stringent. No surprise, therefore, that the industry has seen an exponential growth in the demand for alternatives to flexible plastic packaging. UPM Specialty Papers and Unipaco teamed up to find an answer to the challenge in one specific area: wrapper for salad and herb pots.<\/p>\n\n\n\n UPM Solide\u2122 Lucent 78 g\/m<\/strong>2<\/strong> + 4 g\/m<\/strong>2<\/strong> PE coating<\/strong><\/p>\n\n\n\n The partnership has resulted in two versions of packaging that combine UPM papers and Unipaco coatings. The first is based on innovative barrier base paper UPM Solide\u2122 Lucent 78 g\/m2 with a 4 g\/m2 PE coating. This strong and extremely versatile barrier base paper offers a unique natural look and feel. Proven to be particularly well suited to coating and lamination, UPM Solide\u2122 Lucent provides a superior surface for further converting and printing, including rotogravure. The exceptionally thin 4 g\/m2 PE layer delivers required moisture resistance and heat sealable properties.<\/p>\n\n\n\n \u201cBy combining our papers with an extremely thin PE coating, we set out to create a packaging that helped our customers both to meet their recyclability goals and also comply with all relevant regulations,\u201d explained Kirsi Lahtela<\/strong>, Senior Manager, Product Portfolio Management, UPM Specialty Papers. \u201cThe project provided Unipaco with their first opportunity to test our barrier base papers in addition to more familiar coated one side papers. We were delighted to see that UPM Solide Lucent performed perfectly on the coating equipment.\u201d<\/p>\n\n\n\n UPM FlexPack\u2122 80 g\/m<\/strong>2<\/strong> + 4 g\/m<\/strong>2<\/strong> PE coating<\/strong><\/p>\n\n\n\n The second version pairs UPM FlexPack\u2122 80 g\/m2 with a 4 g\/m2 PE coating. UPM\u2019s coated one side UPM FlexPack\u2122 papers are designed for a wide range of lamination processes and offer an unrivalled combination of strength and high-quality print results – especially on flexo printing. Again, the exceptionally thin and heat sealable 4 g\/m2 PE layer guarantees heat-sealability and the correct level of moisture resistance.<\/p>\n\n\n\n \u201cWith growing demand for recyclable materials, we decided to focus on lowering the grammage of our coating to develop a unique product. Our goal was to create as thin a coating as possible while also maintaining quality, barrier properties, and heat sealability. By combining this coating with UPM\u2019s papers, we achieved astonishing results that can be easily transferred to a full-scale production. This solution is available on many other papers and for a numerous end-uses such as meat and cheese wrapping, flexible packaging and even sack production,\u201d said Aleksander Borysow<\/strong>, CEO and Chairmen of the Board, Unipaco S.A.<\/p>\n","protected":false},"excerpt":{"rendered":" UPM Specialty Papers continues to work with partners across the food packaging value network, co-creating innovative products that help to shape the future of sustainable packaging.
