Printing on silicone-coated surface requires UV-cured ink \u2014 standard flexo ink won&#8217;t adhere. We partnered with a UV ink supplier to develop a food-safe formulation that passed FDA 21 CFR and EU 1935\/2004. The retailer launched 3 SKUs and reordered within 60 days.<\/p><p><strong>What we learned:<\/strong> Printing on parchment paper requires specialty UV inks.

Premium grades handle 230\u00b0C. For BBQ\/grill use above 250\u00b0C, ceramic-enhanced coating is required.<\/p><h3 style=\"margin:16px 0 8px;\">What is the minimum order quantity from China?<\/h3><p>Typically 5-10 tons for standard specs. Custom printing adds a $200-400 plate charge.
