The low profile stops the contents shifting inside and keeps them lying flat. They suit publishers, bookshops and stores that mail printed items.<\/p>\n<p>Corrugated board gives the protection needed against knocks and scuffs, and the flat shape makes parcels easier to stack and move. The page carries a calculator where you set the size and the material before ordering.<\/p>\n<h2>What flat mailer boxes give you<\/h2>\n<ul>\n<li>E-flute corrugated cardboard that protects contents in the post.<\/li>\n<li>Material available in white or brown.<\/li>\n<li>Three ready sizes matched to common print formats.<\/li>\n<li>Printing on the outer and inner surfaces.<\/li>\n<li>Recyclable cardboard construction.<\/li>\n<\/ul>\n<h2>Sizes and options<\/h2>\n<p>You pick the size in the calculator on the page. Three are available: A5 at 21.6 \u00d7 15.6 \u00d7 3 cm, A4 at 30.6 \u00d7 21.6 \u00d7 3 cm and A3 at 42.6 \u00d7 30.6 \u00d7 3 cm.<\/p>\n<p>Next you choose the material, either white E-flute corrugated cardboard or brown E-flute corrugated cardboard, then upload your design file directly from the page.<\/p>\n<p>The calculator adds a supplement according to the size you pick, and that supplement rises with the larger formats. If you have no artwork ready, the design service is an optional extra at a fixed 100 SAR before tax, and it is switched off by default.<\/p>\n<h2>Where it is used<\/h2>\n<ul>\n<li>Posting books to customers and distributors.<\/li>\n<li>Sending catalogues and promotional print.<\/li>\n<li>Mailing formal documents so they stay flat.<\/li>\n<li>Packing printed material that creases easily.<\/li>\n<li>Fulfilling online orders for printed items.<\/li>\n<\/ul>\n<p>Printed material fails differently from other products: the damage is a bent corner rather than a break, and it lowers the value in the recipient\u2019s eyes without making the item unusable. A snug flat box is what prevents exactly that kind of damage.<\/p>\n<h2>How to order<\/h2>\n<p>Choose the size and material in the calculator on the page, then upload your design file or switch on the design service if you need it.
