Roll film:The main advantage of roll film used in the packaging industry is to save costs in the entire packaging process. When roll film is used in automatic packaging machinery, there is no need for the packaging production company to perform any edge sealing work. It only requires a one-time edge sealing operation at the production company. As a result, packaging manufacturers only need to carry out printing operations, and transportation costs are reduced because they are supplied in rolls. When roll film appeared, the entire process of plastic packaging was simplified into three steps: printing, transportation, and packaging. This greatly simplified the packaging process and reduced the cost of the entire industry, making it the first choice for small packaging.
