We source cardboard products made of extra durable corrugated and offer designs made to support contents of all shapes and sizes. 32 ECT vs. 200# Test Find your perfect box with 32 ECT or 200# Test cardboard types. If you anticipate a lot of wear and tear during shipping, consider a 200# box. If you’re stacking boxes onto pallets, use a 32 ECT box. Things To Remember: Inside Dimensions & Usable Space When you’re shopping around for boxes, remember that the measurements listed are the inside dimensions (aka. usable space). Inside dimensions indicate the space available to your item for a comfortable and safe fit. Packaging Basics: Wrap & Cushion To Protect When packing breakable items, provide support on all sides with material flexible enough to get into tight spaces and durable enough to cushion. Consider materials like crinkle cut, bubble wrap, or foam sheets. Natural Packaging Matters Natural packaging is more than just a consumer trend. That’s why we provide a selection of packaging products that are made of natural materials.
