Why Shopping bags in brown color: You must have often bought goods from shopping malls. When you buy things and bring them home, have you ever noticed that most of the bags you got were brown or gray in colour. Ever thought about it? Actually, there are deep secrets hidden behind it. If the bag is not plastic, then in paper bags more than 90 percent of the bag is brown. Let us know the science behind it.
If you have noticed, you would have noticed that whenever you buy something in a shopping mall, you often get the goods in brown colored bags. Have you ever wondered why this happens? The trend of brown colored paper bags in shopping malls is not just a coincidence but there are practical, economic and psychological reasons behind it. Many people do not know why these bags are brown. There are many scientific and industry related reasons behind this.
Craft Process: When paper is made, wood chips are boiled with chemicals like sodium hydroxide and sodium sulfide. This breaks down a substance called lignin present in wood and helps in making paper. After this process the paper is not bleached. Therefore the natural brown color of the wood remains the same. The word ‘Craft’ means ‘strength’ in German.
Most brown bags are made of ‘kraft paper’. The paper is not bleached in the manufacturing process, allowing it to remain in its natural brown color. It is less harmful to the environment and is easily recycled. The fiber structure of unbleached brown kraft paper is stronger than that of white paper bags. The bleaching process weakens the paper fibers. Since people buy heavy items (shoes, clothes, boxes) in malls, brown bags are more reliable to handle the weight.

Strength and Durability: When paper is bleached, its fibers become slightly weaker. According to research, the strength of bleached paper reduces by about 10–15 percent. But in unbleached kraft paper the fibers remain long and strong. So these brown paper bags are sturdy and good for carrying groceries or heavy items.
Lower production costs: If the process of bleaching paper is skipped, production steps are reduced. It does not require many chemicals. With this, factory expenses can be reduced by about 15-20 percent. Therefore, it is economically easier to make and use brown paper bags.
Better for the environment: Unbleached kraft paper uses fewer chemicals. Therefore, they can be easily recycled and dissolve quickly in the soil. Sometimes these can also become compost. For this reason, they cause less harm to the environment than plastic bags. Due to new environmental policies and anti-plastic measures, the use of such paper bags has increased all over the world.
Natural Look: Many companies intentionally use brown paper bags. Consumers consider this color to be ‘natural’, ‘organic’ or good for the environment. This creates a good image and identity of the company. White kraft bags are also made as per requirement. To clearly print colored logos or designs on them, they are bleached and made white. Such white bags are usually used in clothing stores, gift items or branded products. But unbleached brown paper bags are considered more beneficial in terms of energy saving and environmental protection.
According to psychology, brown color conveys stability, reliability and a feeling of being ‘organic’. In today’s ‘sustainability’ branding, companies deliberately use brown bags to show themselves being environmentally conscious. White bags get dirty very quickly or scratch marks are clearly visible on them. On the contrary, brown color easily hides dust or light stains, which makes the bag look neat and clean when you take it home after shopping.
Simply put, the brown color of the paper bag is not a trivial matter. On the one hand, it is the result of the factory process and on the other hand, things like energy saving, reducing expenses and environmental protection are associated with it.
