it depends on which backpack. most of their backpacks are made of canvas. Some have suede bottoms. They have also made leather backpacks.
Polypropylene is made primarily from oil or natural gas, though it can be made from coal.
PVC (polyvinyl chloride) is made primarily from two raw materials: ethylene, which is derived from natural gas or petroleum, and chlorine, which is obtained from salt. These raw materials are combined through a chemical process to create PVC resin, which is then processed into a multitude of products.
Smart phones are made of metal and computer soft ware
The formula for raw materials typically refers to the quantity and cost of materials needed for production. It can be expressed as: Raw Materials Cost = Quantity of Raw Materials × Unit Cost of Raw Material. This formula helps businesses calculate the total expense incurred in acquiring the raw materials required for manufacturing their products. Additionally, in a broader context, raw materials can be categorized based on their types or sources, such as natural resources or processed inputs.
Raw materials: glucose and oxygen Products: carbon dioxide and water And, of course, energy.

Raw materials
The same as any other machine. Raw materials are purchased and made to specifications.
Earlier civilizations primarily used natural raw materials for their daily needs, such as stone, wood, clay, and animal hide. As civilizations progressed, they began to incorporate more man-made materials, such as metals, glass, and various alloys, into their technologies and artifacts. However, natural materials continued to play a significant role in early civilizations due to their abundance and accessibility.
When products are made, raw materials are transformed through a manufacturing process. Bonds between atoms in the raw materials may be broken and new bonds are formed to create the final products.
