In the last issue, we introduced you to the market price of plastic granulator at the end of 2024, and in this issue, we popularize the stretch film machine for you, so what is stretch film machine? What is the function of stretch film machine? Here we explain for you one by one, hope it can help you.
Firstly, a stretch film machine is actually an industrial equipment used to produce stretch film. Stretch film is a thin plastic film made primarily from polyethylene and is widely used in packaging and transport to secure and protect palletised goods. Here we also mention the cling film machine, which produces cling film that can be used for food packaging as well as on the winding of food grade items.
Secondly, the core process of a stretch film machine is extrusion, the exact process involves melting and moulding plastic granules (usually polyethylene) into a continuous film. The connector plastic is extruded through a flat die to form wide, next-door plastic sheets. The sheet is then cooled and cured using a series of cooling rollers or an air cooling system. The film is then stretched in both longitudinal and transverse directions, a process that gives the film its characteristic stretch and strength. Finally, the stretched film is wound onto large rolls or spools, ready for further processing or sale.
Finally, the main role of stretch film machine in the packaging industry is that the stretch film can be stretched to wrap around the surface of the goods to protect the goods. For example, in logistics and transport, stretch film can prevent products from collision, friction, humidity and other damages;when counting the goods, stretch film can integrate multiple products into a whole, and at the same time, it is convenient for stacking and management.
