When you step into the world of shrink wrap machines, you're entering a realm with its own language. The terminology surrounding these machines might seem complex at first, but fear not! We're here to unravel the mystery and equip you with the knowledge you need to navigate the world of packaging with confidence. Let's dive into the essential shrink wrap machine terms that will empower you on your packaging journey.
1. Angel Hair
Ever noticed those thin strands of shrink film near the seal? These are aptly referred to as "Angel Hair." While they might look delicate, they can be caused by various issues during the packaging process.
2. Centerfold Shrink Film
Imagine a shrink film folded lengthways and conveniently placed on a roll. That's precisely what centerfold shrink film is. Its practicality lies in its ease of use and application.
3. Chamber Size
When talking about a shrink tunnel, the "chamber size" denotes the dimensions of the heated interior area. This plays a crucial role in determining the capacity and efficiency of the shrink tunnel.
4. Contactor The electrical relay that engages heaters, sealers, or blowing fans on various shrink machines is known as a "Contactor." It's the behind-the-scenes component that ensures the proper functioning of these machines.
5. Control Panel
The nerve center of a sealer or shrink tunnel is the "Control Panel." Here, you'll find a range of settings, including temperature control, conveyor speed, shrink time, seal time, and more. It's where you fine-tune the machine to match your packaging needs.
6. Discharge Conveyor
Picture a conveyor belt situated between an L Bar sealer and a shrink tunnel—this is the "Discharge Conveyor." Its purpose is to smoothly transport sealed products from one stage to another, streamlining the packaging process.
7. Entry Conveyor
For fully automatic shrink wrap machines, the "Entry Conveyor" is a mechanically driven device that transports products into the machine. It's the point of initiation for the packaging process.
8. Exit Conveyor After products have undergone sealing or shrink wrapping, the "Exit Conveyor" takes over. It's a mechanism that uses either mechanical or gravity-driven means to move products from a semi-automatic or fully automatic shrink wrap machine.
9. Film Build Up
Over time, a "Film Build Up" can occur on a sealer—a residue of black film that accumulates after multiple seals. While not harmful, it's essential to keep an eye on it for optimal machine performance.
10. Micro Knife/Band Ribbon
Meet the modern alternative to sealing wires—Micro Knife or Band Ribbon. Found beneath sealing bars, these thicker and sturdier elements are capable of sealing and cutting numerous products before needing replacement.
11. Seal Time
"Seal Time" is the specified duration set to complete a seal on flexible plastic materials. Getting this timing right ensures a secure and professional seal.
12. Shrink Time
"Shrink Time" is a critical parameter. It's the time set to apply heat to a shrink film, enabling it to achieve the proper shrink rate and wrap snugly around the product
13. Shrink Tunnel
At the heart of many packaging processes lies the "Shrink Tunnel." This heating element, often coupled with a conveyor system, heats the packaging area to efficiently shrink the film around the products.
14. Teflon Tape
To reduce film build-up directly on sealing wires and bumpers, "Teflon Tape" comes to the rescue. Made from PTFE extruded material, this chemical-resistant tape helps maintain machine efficiency.
15. Transit Channel When it comes to holding band ribbons in place, the "Transit Channel" takes the stage. This ceramic channel ensures these vital components stay in position during the sealing process.
Armed with this glossary, you're ready to converse fluently in the language of shrink wrap machines. Whether you're seeking to troubleshoot issues, optimize settings, or simply better understand the intricacies of the packaging process, these terms will serve as your guide. Remember, knowledge is power, and mastering these terms empowers you to achieve packaging excellence.
