2. Paper Bag Manufacturing: A Step-by-Step Guide

2.1 Selecting Raw Materials

The creation of paper bags begins with selecting appropriate raw materials. Sustainable and recycled paper materials, such as kraft paper, recycled paper, and specialty papers, are commonly used.

• Kraft paper, is a strong and durable option known for its tear resistance.
• Recycled paper, minimizes the need for virgin wood pulp, reducing environmental impact.
• Specialty papers, such as laminated or coated papers, provide additional functionality, like moisture resistance, or enhance aesthetic appeal.

In making their pulp, fillers and additives, including minerals and chemicals, are incorporated into the pulp to improve the paper’s strength, opacity, and printability.

2.2 Papermaking

2.2.1 Pulping Processes

The transformation of raw materials into paper involves several crucial steps. The initial stage is pulping, where wood chips or recycled paper are broken down into a fibrous slurry called pulp using either mechanical or chemical processes. Mechanical pulping grinds the wood into fibers, while chemical pulping uses chemicals to dissolve lignin and separate cellulose fibers.

2.2.2 Refining and Sheet Formation

After pulping, the pulp undergoes refining to achieve the desired consistency and fiber length, influencing the final paper’s strength and texture. For example, in the study applied for by Kemira, the pulp is diluted to a specific consistency (e.g., 0.8% or 1.75%) and then further refined to achieve the desired SR value (Shear Resistance value), which ensures that the pulp has the proper consistency and fiber length. Subsequently, the refined pulp is spread onto a moving mesh screen, forming a wet sheet of paper in a process known as sheet formation.

2.2.3 Pressing and Drying

The wet paper sheet then passes through a series of rollers and presses to remove excess water. Finally, the paper is dried using heated cylinders or large air dryers, reducing the moisture content to between 4-8%.

2.3 Bag Formation

2.3.1 Sheeting and Printing

Large rolls of paper are sheeted, or cut into sheets of specific dimensions, based on the desired bag size. For branded or customized bags, the paper sheets are printed using various methods, including flexography, offset printing, screen printing, and digital printing.

• Flexography, which uses flexible plates and water-based inks, is a cost-effective and environmentally friendly option for large-scale printing.
• Offset printing, yields high-quality, detailed graphics but is typically slower and more expensive than flexography.
• Screen printing, excels in producing vibrant, saturated colors for smaller quantities or bold designs.
• Digital printing, offers flexibility for short runs and complex designs without requiring printing plates.

In addition to this, the design of paper bags often combines traditional craftsmanship with modern technology in the production of jewellery packaging. For example, using the technique of quilling, thin strips of paper can be curled into intricate shapes to create unique jewellery packaging.

2.3.2 Cutting and Folding

The printed paper sheets are then fed into a bag-making machine, which precisely folds and shapes the paper into a continuous tube. This tube is then cut to the desired bag length, and the bottom of the bag is formed using adhesives. Depending on the intended use, various bag styles are produced, including flat bags, satchel bags, and block bottom bags.

2.3 Handle Attachment

Handles, typically made of twisted paper, flat tape, or other materials, are attached to the bags for carrying convenience. Attachment methods include adhesives or mechanical fasteners.

• Adhesive is very suitable for eco-friendly packaging paper bags and can be done through simple steps. First, a string or ribbon of the desired length is cut into two pieces, which are then folded and adhered to the inside of the paper bag. The other is to fold strips of paper into the desired shape and stick them to the outside or inside of the bag.
• Mechanical fasteners are often used in mass production to increase efficiency and ensure the quality of the handles. In some paper bag manufacturing processes, specialized machines can be used to attach the handles. These machines are capable of attaching paper string or paper tape to the paper bag and ensuring that the handles are firmly attached to the bag.
