During the repulping process, PE tends to <strong>separate from the fibers<\/strong> and <strong>can<\/strong> <strong>contaminate them<\/strong>, reducing <strong>the quality and quantity<\/strong> of <strong>recyclable material.<\/strong><\/p>\n<p><strong>Water-based barrier coatings<\/strong>, on the other hand, eliminate this critical issue. They offer strong resistance to moisture and grease, are heat-sealable up to 80\u00b0C, and provide better fiber yield during recycling. They also allow <strong>lower thicknesses <\/strong><strong>(8-12 gsm, down to 5 gsm with flexo application<\/strong>), reducing material consumption and production waste.<\/p>\n<p>In the face of more complex technology and initially higher costs, this solution allows for a <strong>simplification of recycling processes<\/strong>, two factors that are expected to become crucial in the coming years.[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=&#8221;in_container&#8221;
