How Paper Bags are made – Buy bags from Bag Man Packaging

Ever wonder how these paper carry bags are made?

In most cases, paper grocery bags are made from recycled paper, which is gathered and processed in a recycling paper mill. In rare cases, the paper is created from fresh paper pulp, which is essentially thin shavings of wood from trees.

A paper bag is a bag made of paper, usually kraft paper. Paper bags are commonly used as shopping bags, packaging, and sacks.
Standard brown paper bags are made from kraft paper. Tote-style paper bags, such as those often used by department stores or as gift bags, can be made from any kind of paper, and come in any colour. Paper bags can be made from recycled paper, with some local laws requiring bags to have a minimum percentage of post-consumer recycled content.

What is Kraft paper? Kraft paper or kraft is paper or paperboard produced from chemical pulp produced in the kraft process.

Sack kraft paper, or just sack paper, is a porous kraft paper with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability.

Pulp produced by the kraft process is stronger than that made by other pulping processes; acidic sulfite processes degrade cellulose more, leading to weaker fibers, and mechanical pulping processes leave most of the lignin with the fibers, whereas kraft pulping removes most of the lignin present originally in the wood. Low lignin is important to the resulting strength of the paper, as the hydrophobic nature of lignin interferes with the formation of the hydrogen bonds between cellulose (and hemicellulose) in the fibers.

Kraft pulp is darker than other wood pulps, but it can be bleached to make very white pulp. Fully bleached kraft pulp is used to make high quality paper where strength, whiteness, and resistance to yellowing are important.
