Plastic usage is ubiquitous in manufacturing, but it comes with a significant byproduct: scrap. Whether it is sprues from injection molding, edge trims from thermoforming, or defective parts, waste is an inevitable part of the production process. This is where the granulator machine becomes an essential piece of equipment.

Walk into any commercial kitchen or shipping warehouse, and you will likely see rolls of transparent film being pulled, stretched, and wrapped around goods. Plastic wrap is one of the most ubiquitous materials in modern logistics and food preservation. It keeps our leftovers fresh and ensures pallets of merchandise don't topple over during transit.

You are standing in a warehouse looking at a pallet that needs to be secured, or perhaps you are in your kitchen trying to save leftovers. In both scenarios, you reach for a roll of thin, clear plastic. It looks the same, feels somewhat similar, and serves the general purpose of wrapping things up. But is the industrial wrap used for shipping pallets the same as the plastic wrap used for your sandwich?

Have you ever watched a pallet of boxes being wrapped in clear plastic and wondered how a thin layer of material can hold hundreds of pounds of cargo in place? It is a staple in logistics warehouses globally, yet the engineering behind stretch film is often overlooked. It isn’t just about wrapping plastic around a box; it is about physics, material science, and precision machinery.

Stretch film is a staple in the logistics and packaging industry, essential for securing pallets and protecting goods during transport. But have you ever wondered how those rolls of clear, stretchy plastic are actually made? The magic lies in a manufacturing process called extrusion. This sophisticated method transforms raw plastic granules into the thin, durable films we rely on every day.

If you work in packaging or manufacturing, you know that efficient material handling is the backbone of a successful operation. While extrusion lines create the initial film, the process rarely ends there. Jumbo rolls are often too heavy, wide, or unwieldy for end-users to manage effectively. This is where the unsung hero of the packaging world comes in: the rewinder.
