This structure gives the box a high strength-to-weight ratio: a typical 600 \u00d7 400 \u00d7 300 mm box weighs 0.8\u20131.2 kg yet supports 15\u201325 kg of contents stacked 4\u20136 units high.<\/p>\n<p>The &#8220;corrugated&#8221; in the name refers to the fluted core \u2014 identical in principle to corrugated cardboard, but in PP rather than paper.

material-level advantages over cardboard and solid plastic alternatives.<\/p>\n<h4>Waterproof &amp; Chemical-Resistant<\/h4>\n<p>PP corrugated sheet absorbs less than 0.03% moisture by weight \u2014 compared to 6\u20139% for cardboard. The material is inert to water, most acids, alkalis, and organic solvents, making it suitable for wet environments, cold storage, and chemical plants where cardboard delaminates within hours.<\/p>\n<h4>Foldable &amp; Space-Saving (Where Applicable)<\/h4>\n<p>Die-cut fold-up box types (Correx, Hollow Sheet, Foldable) collapse flat when empty, reducing return-shipping volume by 75\u201380%. A standard 600 \u00d7 400 \u00d7 300 mm foldable box packs down to roughly 600 \u00d7 400 \u00d7 40 mm \u2014 enabling 15\u201320 empty boxes to stack in the space of one assembled box. Rigid types (Turnover, Courier) do not fold but are designed to nest inside each other when empty.<\/p>\n<h4>Customizable &amp; Stackable<\/h4>\n<p>PP corrugated boxes accept screen printing, digital printing, and hot-stamping for branding, barcodes, and handling instructions. All types are designed to stack when full (4\u20136 units high for standard boxes; 3\u20134 units for pallet boxes) and nest when empty. Custom sizes, colors, and internal dividers are available on all models with no minimum order quantity.<\/p>\n<h4>PP Corrugated Box vs Cardboard Box vs Solid Plastic Tote<\/h4>\n<table>\n<thead>\n<tr>\n<th>Property<\/th>\n<th>PP Corrugated Box<\/th>\n<th>Cardboard Box<\/th>\n<th>Solid Plastic Tote (PP\/HDPE)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Weight (600\u00d7400\u00d7300 mm)<\/td>\n<td>0.8\u20131.2 kg<\/td>\n<td>0.5\u20130.8 kg<\/td>\n<td>2.0\u20133.5 kg<\/td>\n<\/tr>\n<tr>\n<td>\u627f\u8f7d\u80fd\u529b<\/td>\n<td>15\u201325 kg<\/td>\n<td>10\u201315 kg<\/td>\n<td>25\u201340 kg<\/td>\n<\/tr>\n<tr>\n<td>Reuses<\/td>\n<td>150\u2013500+<\/td>\n<td>1\u20133<\/td>\n<td>500\u20131000+<\/td>\n<\/tr>\n<tr>\n<td>\u9632\u6c34<\/td>\n<td>\u2705<\/td>\n<td>\u274c<\/td>\n<td>\u2705<\/td>\n<\/tr>\n<tr>\n<td>Foldable When Empty<\/td>\n<td>\u2705 (foldable types)<\/td>\n<td>\u2705 (always)<\/td>\n<td>\u274c<\/td>\n<\/tr>\n<tr>\n<td>\u6e29\u5ea6\u8303\u56f4<\/td>\n<td>\u221220\u00b0C to +80\u00b0C<\/td>\n<td>\u22125\u00b0C to +50\u00b0C (dry)<\/td>\n<td>\u221220\u00b0C to +80\u00b0C<\/td>\n<\/tr>\n<tr>\n<td>Chemical Resistance<\/td>\n<td>\u2705<\/td>\n<td>\u274c<\/td>\n<td>\u2705<\/td>\n<\/tr>\n<tr>\n<td>Printable<\/td>\n<td>\u2705<\/td>\n<td>\u2705<\/td>\n<td>\u26a0\ufe0f Limited (in-mold or pad print)<\/td>\n<\/tr>\n<tr>\n<td>\u53ef\u56de\u6536<\/td>\n<td>\u2705 (#5 PP)<\/td>\n<td>\u2705<\/td>\n<td>\u2705 (#5 PP or #2 HDPE)<\/td>\n<\/tr>\n<tr>\n<td>Typical Cost\/Unit<\/td>\n<td>$2\u20138<\/td>\n<td>$0.50\u20132<\/td>\n<td>$8\u201325<\/td>\n<\/tr>\n<tr>\n<td>Cost Per Use (50 reuses)<\/td>\n<td>$0.04\u20130.16<\/td>\n<td>$0.17\u20130.67<\/td>\n<td>$0.16\u20130.50<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<blockquote><p><strong>Takeaway:<\/strong>\u00a0PP corrugated boxes occupy the sweet spot between cardboard (cheap but disposable) and solid plastic totes (durable but expensive and non-foldable).
