Frequently Asked Questions for A3 Printer Paper – Wholesale Large Format Printing Paper Buyers
How does the bending stiffness of A3 paper prevent sheet sag in large copier trays?
Large format A3 (297 x 420 mm) has twice the surface area of A4. Our A3 copy paper is engineered with machine direction stiffness ≥ 145 mN and cross direction stiffness ≥ 65 mN, preventing wide-tray droop and eliminating multi-sheet feed jams in high-speed digital copiers.
Can we combine A3 and A4 copy paper in the same 20ft or 40ft container?
Yes. Mixed container shipments are common. For example, a 20GP container can accommodate 800 cartons of A4 plus 400 cartons of A3, or customized pallet configurations to meet your regional distributor requirements.
What is the exact carton and ream packaging configuration for A3 paper?
Each A3 ream contains 500 sheets wrapped in PE moisture-proof coated kraft. A master carton holds 5 reams (2,500 sheets). Master cartons are heavy-duty 5-ply BC-flute kraft corrugated boxes with high edge crush resistance (ECT ≥ 8.0 kN/m).
How do you protect large A3 cartons against corner damage during freight?
Palletized shipments feature full-height heavy cardboard corner angle protectors, top wooden cover caps, and 5-layer automated tension stretch film wrapping, ensuring cartons arrive at destination in pristine showroom condition.
