Fraunhofer researchers exhibited their work at the Interpack packaging trade show in Dusseldorf in May, and are hopeful that the interest they attracted will come to fruition.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">&#8220;There are not really many paper sealing technologies without any foreign materials, so it&#8217;s a great technology and we feel it&#8217;s likely that we can bring it to market,&#8221; says researcher group leader Fabian Kayatz.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">&#8220;If we are optimistic, we will have the first solution out in two years.&#8221;<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Also in 2023, engineering firm Hermann Ultraschall bought the rights to develop a patented ultrasonic paper sealing technology, a process which it likens to welding.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">&#8220;We are really actively at the moment in discussion with several really big players in the market with the focus of bringing this technology into mass production,&#8221; says Michael Baumann, the company&#8217;s head of business development packaging.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">&#8220;One customer told me this is an innovation they have never seen before.&#8221;<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Yet these seemingly simple solutions stem from complex technology, so naturally, there are challenges.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Firstly, it&#8217;s not as simple as simply getting product manufacturers and packaging companies to swap out their old packaging for these new options. It requires updating, and in some cases, completely replacing, existing machinery, which can be costly and time consuming.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">&#8220;The packaging industry has existing machines which are all designed for glue materials. Some kind of redesign is probably necessary, and this is our biggest challenge,&#8221; says Hermann Ultraschall&#8217;s Baumann.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Yet Volker Franke, also a research group leader at Fraunhofer, is confident that those existing machines can be modified by integrating the laser module that PAPURE has been developing.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">They both acknowledge that the production rate is also currently much slower than that for paper packaging that uses adhesives, but Franke says a key benefit PAPURE is selling is fully automated production, which he believes can continue to be developed for speed.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">The other issue is that the technologies don&#8217;t work on all types of paper.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">&#8220;It&#8217;s not possible to bond every paper material,&#8221; Baumann confirms. &#8220;But we are actively in discussion with paper manufacturers about how they can produce a raw material in a way that makes it easy to bond.&#8221;<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">PAPURE has also yet to find a way to apply their laser sealing technology to food-grade packaging, which needs a coating to protect the item. This tends to be why plastic is often favoured for packaging food.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">But this is something Henkel, with both a consumer brand division, and adhesive technologies division, has cracked.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">In February, Henkel announced the launch of the first cold seal solution that works with barrier coated paper, which is both recyclable and suitable for food products.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Barrier paper can be a difficult surface to bond, and using heat isn&#8217;t suitable for heat sensitive food products like ice cream or chocolate. Hence the cold seal solution, in which enough pressure is applied for the barrier coated paper to be bonded against itself.<\/p>\n<\/div>\n<p><!-- \u603b\u5bb9\u5668\uff1a\u6700\u5927\u5bbd908px Grid\u7d27\u51d1\u5e03\u5c40 -->\r\n<div style=\"display: grid; grid-template-columns: 728px 160px; gap:2px; width:908px; background:#eee; padding:2px;\">\r\n\r\n  <!-- \u901a\u680f\u9876\u90e8\uff1a\u6700\u5927\u6a2a\u5e45 908x258 \u8de8\u6574\u884c -->\r\n  <div style=\"grid-column:1\/-1; height:258px; background:#ff6b6b; display:grid; place-items:center;\">\r\n    <!-- JuicyAds v3.0 -->\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async src=\"https:\/\/poweredby.jads.co\/js\/jads.js\"><\/script>\r\n<ins id=\"1114307\" data-width=\"908\" data-height=\"258\"><\/ins>\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async>(adsbyjuicy = window.adsbyjuicy || []).push({'adzone':1114307});<\/script>\r\n<!--JuicyAds END-->\r\n  <\/div>\r\n\r\n  <!-- \u7b2c\u4e8c\u901a\u680f\uff1a728\u00d790 \u901a\u680f -->\r\n  <div style=\"grid-column:1\/-1; height:90px; background:#4ecdc4; display:grid; place-items:center;\">\r\n    <!-- JuicyAds v3.0 -->\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async src=\"https:\/\/poweredby.jads.co\/js\/jads.js\"><\/script>\r\n<ins id=\"1114300\" data-width=\"728\" data-height=\"90\"><\/ins>\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async>(adsbyjuicy = window.adsbyjuicy || []).push({'adzone':1114300});<\/script>\r\n<!--JuicyAds END-->\r\n  <\/div>\r\n\r\n  <!-- \u5de6\u4fa7\u4e3b\u680f\uff1a\u591a\u5e7f\u544a\u5806\u53e0 -->\r\n  <div style=\"display:grid; gap:2px;\">\r\n    <div style=\"height:60px; background:#45b7d1; display:grid; place-items:center;\">\r\n\t<!-- JuicyAds v3.0 -->\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async src=\"https:\/\/poweredby.jads.co\/js\/jads.js\"><\/script>\r\n<ins id=\"1114308\" data-width=\"468\" data-height=\"60\"><\/ins>\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async>(adsbyjuicy = window.adsbyjuicy || []).push({'adzone':1114308});<\/script>\r\n<!--JuicyAds END-->\r\n\t<\/div>\r\n    <div style=\"height:250px; background:#ffe066; display:grid; place-items:center;\">\r\n\t<!-- JuicyAds v3.0 -->\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async src=\"https:\/\/poweredby.jads.co\/js\/jads.js\"><\/script>\r\n<ins id=\"1114299\" data-width=\"300\" data-height=\"250\"><\/ins>\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async>(adsbyjuicy = window.adsbyjuicy || []).push({'adzone':1114299});<\/script>\r\n<!--JuicyAds END-->\r\n\t<\/div>\r\n    <div style=\"height:250px; background:#ff9ecd; display:grid; place-items:center;\">\r\n\t<!-- JuicyAds v3.0 -->\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async src=\"https:\/\/poweredby.jads.co\/js\/jads.js\"><\/script>\r\n<ins id=\"1114305\" data-width=\"250\" data-height=\"250\"><\/ins>\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async>(adsbyjuicy = window.adsbyjuicy || []).push({'adzone':1114305});<\/script>\r\n<!--JuicyAds END-->\r\n\t<\/div>\r\n    <div style=\"height:139px; background:#c792ea; display:grid; place-items:center;\">\r\n\t<!-- JuicyAds v3.0 -->\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async src=\"https:\/\/poweredby.jads.co\/js\/jads.js\"><\/script>\r\n<ins id=\"1114302\" data-width=\"133\" data-height=\"139\"><\/ins>\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async>(adsbyjuicy = window.adsbyjuicy || []).push({'adzone':1114302});<\/script>\r\n<!--JuicyAds END-->\r\n\t<\/div>\r\n    <div style=\"height:125px; background:#91e7ac; display:grid; place-items:center;\">\r\n\t\r\n<!-- JuicyAds v3.0 -->\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async src=\"https:\/\/poweredby.jads.co\/js\/jads.js\"><\/script>\r\n<ins id=\"1114303\" data-width=\"125\" data-height=\"125\"><\/ins>\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async>(adsbyjuicy = window.adsbyjuicy || []).push({'adzone':1114303});<\/script>\r\n<!--JuicyAds END-->\r\n\t<\/div>\r\n  <\/div>\r\n\r\n  <!-- \u53f3\u4fa7\u7ad6\u680f\uff1a160\u00d7600 \u6574\u5217\u9ad8\u5e7f\u544a -->\r\n  <div style=\"grid-row:3\/8; height:600px;  display:grid; place-items:center;\">\r\n    <!-- JuicyAds v3.0 -->\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async src=\"https:\/\/poweredby.jads.co\/js\/jads.js\"><\/script>\r\n<ins id=\"1114301\" data-width=\"160\" data-height=\"600\"><\/ins>\r\n<script type=\"text\/javascript\" data-cfasync=\"false\" async>(adsbyjuicy = window.adsbyjuicy || []).push({'adzone':1114301});<\/script>\r\n<!--JuicyAds END-->\r\n  <\/div>\r\n\r\n<\/div><br \/>\n<br \/><a href=\"https:\/\/www.bbc.co.uk\/news\/articles\/c872nj1n4xyo?at_medium=RSS&#038;at_campaign=rss\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>But what if you could skip the adhesive altogether?
