The main advantage of using roll film in the packaging industry is cost savings in the entire packaging process. The application of roll film in automatic packaging machinery does not require any edge sealing work by the packaging production company, and only requires a one-time edge sealing operation by the production company. Therefore, packaging manufacturers only need to carry out printing operations, and transportation costs are reduced due to the supply of roll materials. The emergence of the roll film process simplifies the entire process of plastic packaging into three major steps: printing, transportation, and packaging. It greatly simplifies the packaging process, reduces costs, and reduces the cost of the entire industry. Production has become the first choice for small packaging.
