In today’s fast-moving logistics and industrial packaging world, ensuring product safety during storage and transportation is a top priority. Stretch hood packaging—a method using highly stretchable film to tightly secure palletized goods—is gaining popularity due to its efficiency, cost-effectiveness, and superior protection. But at the core of this method is a critical piece of equipment: the Stretch Hood Film Making Machine.
This article will explore what a stretch hood film making machine is, how it works, and why innovative manufacturers like Dostar Packing Equipment Co., Ltd. are driving progress in automated packaging solutions through such advanced machinery.
What Is a Stretch Hood Film Making Machine?
A Stretch Hood Film Making Machine is a specialized production system designed to manufacture highly elastic, multilayer polyethylene (PE) film rolls used in stretch hood wrapping. These films are typically used in automated pallet packaging systems, where the film is stretched and applied over a loaded pallet like a sleeve, offering superior load stability and weather resistance.
This machine is vital for producing films that meet the high-performance demands of sectors like food and beverage, chemicals, building materials, logistics, and warehousing.
Key Functions of a Stretch Hood Film Making Machine
The process of making stretch hood film involves several precise stages, all integrated into one continuous operation. Here's how the machine typically works:
1. Extrusion and Co-Extrusion
At the heart of the machine is the film extrusion system, where raw polyethylene materials are melted and forced through a die to form tubular or flat films. In modern systems, co-extrusion allows multiple layers (often 3–5 layers) to be created simultaneously, combining different material properties such as stretchability, puncture resistance, and UV protection.
2. Bubble Cooling and Sizing
Once the film is extruded, it’s inflated into a bubble and rapidly cooled using an air ring or water-based system. This cooling process helps maintain the film’s structural integrity and clarity.
3. Flattening and Haul-Off
The cooled bubble is collapsed into a flat film using guide rollers and nip rollers. This step ensures that the film maintains a consistent thickness and surface quality.
4. Edge Trimming and Width Control
Precision blades or slitting devices trim the film to exact widths, ensuring the roll matches packaging machine specifications. Width accuracy is crucial for automated stretch hooding systems to work effectively.
5. Winding
The final film is tightly wound into rolls with consistent tension using automated winding systems, ready for use in stretch hood wrapping equipment.
