WHAT IS THE CONVERTING INDUSTRY ?
The term converting industry refers to the manufacturing practices behind the processing of materials in thin layer form. These materials may be:
- Plastic films
- Nonwoven materials
These materials are typically stored and shipped in wound, roll form. Rolls can be as small as a few inches in diameter and as large as many feet in diameter. Material width can vary from a fraction of an inch to many feet wide.
Examples of converting processes are:
- Slitting (making narrow rolls from wide rolls)
- Die cutting (cutting pieces from the web)
These processes can run from very slow speeds; less than one foot per minute to very high speeds; thousands of feet per minute. Processes can include high levels of technology and sophistication. Most processes are somewhat custom in nature.
Material rolls are typically unwound from roll form in a single layer. They are processed and then rewound into roll form for shipping or further processing. This single layer of material is referred to as a “web” as it flows through a machine or process.
Simply put, “converting” means that a roll of material is processed and becomes a roll of something else… it is converted. For example, an unprinted roll of paper becomes a printed roll of paper, a wide roll of film becomes several narrow rolls of film or an uncoated textile becomes adhesive through a coating process. There are countless converting processes, these are just a few examples.
