The key challenge: perforations must be clean-cut without silicone residue blocking the holes. Standard mechanical perforation left 12% of holes partially blocked. We switched to laser perforation \u2014 100% open holes, consistent 5mm spacing. The product became the #1 seller in the buyer&#8217;s Coupang store within 3 months.<\/p><p><strong>What we learned:<\/strong> For perforated baking\/air fryer paper, laser perforation is worth the 8-10% cost premium over mechanical.

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.
