Flat packs in recycled board
Book wraps are described as 100% recycled E-flute, biodegradable and recyclable. M-envelope boxes are the Tenvolope brand, 100% recycled and fully recyclable. They are the flat packs, not a deep single wall cube.
The eco-friendly category gathers them with kraft at 88 gsm and Xtegra gummed paper tape. It is not a statement about every other Packaging Boxes carton.
