How Are Paper Grocery Bags Made?

Preparing Paper Pulp

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. This pulp is put through various mechanical and chemical processes to achieve a certain color and weight of paper. The paper has to be debarked, de-inked and cleaned numerous times to achieve a quality and professional look.

Pressing the Pulp into Paper

The prepared pulp is put into the paper-making machine. This machine resembles a traditional printer in a sense, but instead of printing ink, it rolls out blank sheets of paper that are made by compressing the pulp into thin and long slices. Various sizes of drums and different levels of chemicals and pulp material produce different types of paper sheets. The sheets are rolled up and cut into manageable sizes before being prepared for final assembly or cutting.

Creating Grocery Bags

The sack-making machine automatically pulls rolls of paper and cuts them into the proper size. The cut sheets of paper are folded and glued together by the machine. At the end, a batch of grocery bags is wrapped together either by a string or a plastic seal. The batches are then delivered to their final destination at your local grocery store.
