As a professional plastic bag(https://www.chinazhensi.com/product/packaging-bag/) manufacturer, we understand that our products need to strike a balance between convenience, cost-effectiveness and environmental responsibility. Today, we will take you into the production process of plastic bags and learn how it is transformed from raw materials into convenient packaging in your hands.

The production of plastic bags begins with the selection of raw materials. We usually use plastic particles such as polyethylene (PE), polypropylene (PP) or polyvinyl chloride (PVC) as raw materials. These plastic particles have good fluidity at high temperatures and can be processed into films. Our raw materials are strictly screened to ensure their quality and safety meet international standards.

Next, these plastic pellets are fed into a film blowing machine for heating and melting. Under high temperatures, plastic particles gradually melt into a viscous liquid. Subsequently, the molten plastic is blown into a film through the mold of the film blowing machine. In this process, we can control the thickness and size of the film by adjusting the machine parameters to meet the needs of different customers.
