Kraft Papers / Eco Friendly Materials

Kraft comes from the German word meaning strong. Kraft paper is made from at least 80% sulfate wood pulp. It is course and exceptionally strong, making it well suited for a packaging substrate. It is sometimes made with a rough surface to prevent bags from sliding off pallets.
Its clean and durable fiber content and its low cost make it an ideal option for heavy-duty applications that require a high level of tear resistance. Plus, it’s perfect for printing as well, so it’s a natural for branded packaging and protective layering, wrapping, pallet interleaving, carrier sheets, and dunnage.
Natural kraft paper is the strongest of the common packaging papers and is used when maximum strength is required, such as in industrial bags, grocery bags, inner plies of multiwall sacks, or plain wrapping paper. Kraft fibers are also used to produce liner of corrugated board.

 

As we’ve already alluded to, kraft paper is a strong brown paper that is excellent for paper packaging. Developed in 1879 by Carl F. Dahl, kraft paper was named after the German word kraft, meaning ‘strength’. Kraft paper is produced during the sulfate pulping process – the chemical conversion of wood into wood pulp.

 

Brown Kraft paper is unbleached to retain the natural wood colour and keep chemical treatments to a minimum, making it a 100% natural biomaterial and a genuine ecological alternative: it is bio-based, biodegradable, recyclable and compostable. Kraft paper is a natural, biodegradable and compostable material.
The disadvantage of kraft paper bag is that it can’t meet water, it will soften when it meets water. It needs to keep ventilated and dry. Another small disadvantage is that the fine pattern printed on kraft paper bag can’t achieve that effect. Because kraft paper is rough, ink printing will have uneven ink.
