Understanding these variables determines whether your bag, wrap, or liner passes audit.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>Virgin vs. Recycled Kraft: The Core Food Safety Distinction<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\"><strong style='color:#0f172a;'>Virgin kraft<\/strong> is manufactured from freshly pulped softwood via the kraft (sulfate) process. The pulping chemicals are fully washed out, and unbleached grades retain natural lignin without chlorine-based bleaching byproducts. For direct dry-food contact\u2014flour bags, produce bags, sandwich wrap\u2014virgin kraft at 60\u2013120 GSM is the default compliant substrate.<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\"><strong style='color:#0f172a;'>Recycled kraft<\/strong> carries inherent food-safety limitations. Post-consumer fiber may contain mineral oil hydrocarbons (MOSH\/MOAH), heavy metals, and residual inks. Under 2026 EU enforcement trends, recycled fiber for direct food contact requires functional barriers or de-inking validation. Standard recycled kraft is limited to secondary\/outer packaging or non-food applications.
