This article delves into the intricacies of flow wrap packaging, unveiling its benefits, applications, and the materials that make it an indispensable tool in modern manufacturing.
What Is Flow Wrap Packaging?
Flow wrap packaging, also known as horizontal form-fill-seal (HFFS), is a packaging method wherein products are enveloped in a continuous film of plastic or other materials, then sealed and cut into individual units. This method is characterized by its high-speed operation and adaptability to various product shapes and sizes. From confectionery to hardware, flow wrap packaging ensures products are securely encased, enhancing both their shelf appeal and protection.
How Does Flow Wrapping Machine Work?
The flow wrapping process begins with the unwinding of the packaging film from a roll. This film is then guided through a series of forming collars and tubes, which shape it into a continuous, hollow tube. As the product moves into this tube, the flow wrapper machine simultaneously seals the film along its length, creating a seam, and cuts it into individual packages. The end seals are made using heat or adhesive, depending on the material and product requirements. This seamless integration of forming, filling, and sealing underscores the efficiency of flow wrapping machines.
