Versatile, robust, and reliable, it is at the heart of most of our solutions, both in our standard product ranges and in the creation of custom packaging.<\/p><p>Particularly valued for its thermal and chemical resistance, PP is perfectly suited for applications in <strong>direct contact with food<\/strong>. It is therefore widely used for reusable containers, trays, and logistics crates. <strong>This material<\/strong> also offers high durability, allowing it to withstand intensive washing cycles without any loss of performance.<\/p><p>\u00a0<\/p><h3>PET &amp; R-PET<\/h3><p><a href=\"https:\/\/www.knauf-industries.com\/en\/pet\/\">PET <\/a>(polyethylene terephthalate) is an essential material <strong>for<\/strong> food packaging thanks to its transparency and barrier properties. Among its advantages are effective protection against oxygen and moisture, good mechanical resistance, and a high degree of adaptability to <strong>rigid food packaging<\/strong>. R-PET, derived from recycling, helps <a href=\"https:\/\/www.knauf-industries.com\/en\/plastic-carbon-footprint\/\">reduce the environmental footprint<\/a> by limiting dependence on petroleum resources while maintaining performance suitable for a wide range of uses.<\/p><p>\u00a0<\/p><h3>Expanded Polystyrene (EPS)<\/h3><p><a href=\"https:\/\/www.knauf-industries.com\/en\/expanded-polystyrene\/\">EPS <\/a>is widely used in <strong>the food industry for<\/strong> its exceptional insulating properties. It effectively maintains the temperature of sensitive products, thus preserving the cold chain throughout the logistics process.<\/p><p>It is particularly well-suited <strong>for<\/strong> insulated boxes, transporting fresh or frozen products, and protective packaging. Its lightness and shock absorption capacity make it a <strong>material<\/strong> of choice for securing products during transport.<\/p><p>\u00a0<\/p><h3>New products from Knauf Industries<\/h3><p>We also develop our own new products to meet specific needs:<\/p><h4>Neops\u00ae<\/h4><p>Neops\u00ae is a certified cellular material derived from biomass and an alternative to fossil-based EPS. Thanks to a REDcert\u00b2 certified mass balance approach, it reduces dependence on fossil resources while contributing to a circular economy. Neops\u00ae <strong>maintains the same technical<\/strong>, visual, and thermal performance as conventional EPS and remains recyclable through existing EPS recycling streams.<\/p><h4>KapSeal\u00ae<\/h4><p>KapSeal\u00ae is designed to guarantee optimal sealing of <strong>food packaging<\/strong>. Its characteristics provide enhanced protection against contamination, improved product preservation, and adaptability to specific technical applications. It is particularly relevant for products requiring an effective barrier against air or moisture.<\/p><h4>KapClear\u00ae<\/h4><p>KapClear\u00ae is <strong>the transparent version<\/strong> of KapSeal\u00ae, based on a PP formulation proprietary to Knauf Industries. It <strong>combines the same technical performance<\/strong> in terms of sealing and thermal resistance with a major aesthetic advantage: highlighting the freshness and quality of the products. This material is ideal for packaging where visibility, protection, and compatibility with pasteurization and microwave heating are essential.<\/p><h4>KapLight\u00ae<\/h4><p>KapLight\u00ae is a material chosen primarily for its lightness and mechanical properties, which are well-suited to <strong>the demands<\/strong> of the <strong>food<\/strong> industry. A <strong>black material<\/strong>, but without the addition of carbon black, KapLight\u00ae can be detected in sorting centers, enabling its recycling.<\/p><h4>R\u2019Kap\u00ae<\/h4><p>R\u2019Kap\u00ae is a <strong>plastic material<\/strong> used by Knauf Industries in <strong>the food<\/strong> industry, allowing manufacturers to participate in a circular economy approach. It is a certified single-material made from post-consumer recycled plastics*.<\/p><p><em>*These claims are substantiated; please contact us for more information.<\/em><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-aa90ff7 elementor-widget elementor-widget-menu-anchor\" data-id=\"aa90ff7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"menu-anchor.default\">\n\t\t\t\t\t\t\t<div class=\"elementor-menu-anchor\" id=\"partie4\"><\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-879c2a1 elementor-widget elementor-widget-text-editor\" data-id=\"879c2a1\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h3><span style=\"color: #ffffff;\">Conclusion\u00a0<\/span><\/h3><div class=\"flex-1 overflow-hidden overflow-y-auto\"><div class=\"dark:gpt-dark-gray relative h-full\"><div class=\"flex flex-col pb-9 text-sm dark:bg-transparent\"><div class=\"text-token-text-primary w-full border-0 bg-transparent dark:border-0 dark:bg-transparent\"><div class=\"m-auto justify-center p-4 py-2 text-base md:gap-6 \"><div class=\"final-completion group mx-auto flex flex-1 gap-3 text-base md:max-w-3xl md:px-5 lg:max-w-[40rem] lg:px-1 xl:max-w-[48rem] xl:px-5\"><div class=\"relative flex w-11\/12 flex-col agent-turn\"><div class=\"flex-col gap-1 md:gap-3\"><div class=\"flex max-w-full flex-grow flex-col gap-0\"><div class=\"text-message flex min-h-[20px] flex-col items-start gap-3 overflow-x-auto [.text-message+&amp;]:mt-5\"><div id=\"content_82e542c6-2a71-4088-a7bf-4fdcb588bfc0\" class=\"markdown prose dark:prose-invert light w-full break-words dark:text-gray-100\"><p>With a wide range of technical characteristics and extensive customization options, plastic materials are now perfectly suited to <strong>the challenges<\/strong> of the food <strong>industry<\/strong>.

b\u00e2timent, l\u2019automobile, l\u2019agroalimentaire et l\u2019industrie. Apr\u00e8s avoir accompagn\u00e9 le march\u00e9 du B\u00e2timent en tant que cheffe de produits jusqu\u2019en mars 2025, je pilote d\u00e9sormais les campagnes marketing. Mon r\u00f4le : transformer des sujets techniques en contenus clairs et utiles \u2014 guides, d\u00e9cryptages, cas d\u2019usage et actualit\u00e9s \u2014 pour faciliter la prise de d\u00e9cision et l\u2019adoption sur le terrain. Les articles que je signe mettent en perspective nos solutions, expliquent concr\u00e8tement leur valeur et \u00e9clairent les tendances du march\u00e9 afin de r\u00e9pondre aux questions cl\u00e9s de notre audience. Je m\u2019attache \u00e0 proposer des ressources fiables, actionnables et orient\u00e9es r\u00e9sultats, con\u00e7ues pour am\u00e9liorer la compr\u00e9hension, la performance et la relation avec nos partenaires. Mon ambition: offrir des informations transparentes et pertinentes, et faire des contenus un v\u00e9ritable levier de confiance et d\u2019efficacit\u00e9 pour les secteurs que nous adressons.","url":"https:\/\/www.knauf-industries.com\/en\/blog\/author\/clementine-schmittknauf-com\/"}]}},"_links":{"self":[{"href":"https:\/\/www.knauf-industries.com\/en\/wp-json\/wp\/v2\/posts\/29999","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.knauf-industries.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.knauf-industries.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.knauf-industries.com\/en\/wp-json\/wp\/v2\/users\/16"}],"replies":[{"embeddable":true,"href":"https:\/\/www.knauf-industries.com\/en\/wp-json\/wp\/v2\/comments?post=29999"}],"version-history":[{"count":4,"href":"https:\/\/www.knauf-industries.com\/en\/wp-json\/wp\/v2\/posts\/29999\/revisions"}],"predecessor-version":[{"id":30003,"href":"https:\/\/www.knauf-industries.com\/en\/wp-json\/wp\/v2\/posts\/29999\/revisions\/30003"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.knauf-industries.com\/en\/wp-json\/wp\/v2\/media\/25405"}],"wp:attachment":[{"href":"https:\/\/www.knauf-industries.com\/en\/wp-json\/wp\/v2\/media?parent=29999"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.knauf-industries.com\/en\/wp-json\/wp\/v2\/categories?post=29999"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.knauf-industries.com\/en\/wp-json\/wp\/v2\/tags?post=29999"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
