A shrink wrap machine is a heated tunnel with a conveyor system running through it. The heat settings and conveyor speed of the shrink tunnel can be adjusted to properly heat a shrink film. As businesses seek advanced solutions to streamline their operations, POLYPACK emerges as a reliable partner with its cutting-edge shrink wrap machines. In this blog, we delve into POLYPACK's offerings, focusing on their open side pack and total closure pack machines, shedding light on the diverse range of solutions they provide.
OPEN SIDE PACK shrink MACHINES:
POLYPACK's CLEARPRINT TANGO SERIES stands out as a versatile shrink bundler catering to both clear and printed film applications. Whether you are packaging clear products or those adorned with vibrant prints, this series ensures a snug and secure wrap.
For products longer than 4 inches, the IL SERIES offers an inline shrink wrapper with a simple belt-to-belt product transfer, delivering a precise bullseye/sleeve wrap.
POLYPACK's ILB & CMB SERIES introduces inline bucket conveyor shrink wrap machines designed specifically for bullseye/sleeve wraps, ensuring a tailored solution for various packaging needs.
The TUBE SERIES, a fully automatic machine for shrink wrapping tubes, boasts a patented pick-and-place system, guaranteeing efficiency and accuracy in the packaging process.
When it comes to continuous motion shrink wrapping for products longer than 4 inches, the CMS SERIES steps in as a reliable solution, providing speed and consistency.
Handling ovals, tubes, and other potentially unstable products is made easy with POLYPACK's PH/PHARMA SERIES pick-and-place equipment, ensuring a secure and reliable packaging process.
Introducing POLYPACK's all-in-one shrink bundler and tray former! The CPT machine's rotary gate system efficiently releases your products onto a flight bar for collation. A vacuum picker unloads corrugate blanks from a magazine onto a conveyor, which then delivers them beneath the product bundles. After a spray of adhesive glue, side guides fold the ends of the blank to fully shape the tray. The wrap-arm applies film around the bundle, and as it passes through the shrink tunnel, a perfectly formed, shrink-wrapped tray is delivered ready for your distribution and retail needs.
TOTAL CLOSURE PACK shrink wrap MACHINES:
Forming head inline shrink wrap machines designed for products of any length, the FIL SERIES ensures a secure total closure shrink wrap for various applications.
For high-speed operations, the CFH SERIES offers continuous motion total closure shrink wrappers, delivering efficiency without compromising on quality.
POLYPACK's FH SERIES introduces an intermittent motion pusher machine designed for total closure shrink wrapping, catering to diverse packaging needs.
SHRINK WRAP MACHINE TERMS: DECODING THE JARGON
1. ANGEL HAIR
Thin strands of shrink film on the edges by the seal can be caused by a variety of issues, such as improper sealing or inconsistent heat distribution.
2. Centerfold Shrink Film
A shrink film folded lengthways and placed on a roll, providing a convenient and easily dispensed form for packaging.
3. Chamber Size
Referring to a shrink tunnel, the chamber is the size of the heated interior area where the shrink process takes place.
An electrical relay used to engage heaters, sealers, or blowing fans on a variety of shrink machines, ensuring precise control of the different elements.
5. Control Panel
The main operating panel for a sealer or shrink tunnel, often consisting of temperature control, conveyor speed, shrink time, seal time, and more. It provides a centralized interface for machine operation.
6. Discharge Conveyor
A conveyor belt between an L Bar sealer and shrink tunnel used to transport sealed products, facilitating the smooth flow of the packaging process.
7. Entry Conveyor
A mechanically driven product transportation device used to move products into a fully automatic shrink wrap machine, marking the beginning of the packaging process.
8. Exit Conveyor
A mechanically or gravity-driven product transportation device used to move products from a semi-automatic or fully automatic shrink wrap machine, completing the packaging cycle.
9. Film Build Up
The accumulation of black film residue on a sealer after multiple seals, which can affect the quality of subsequent seals.
10. Film Rack
A film holder used to dispense film for shrink wrapping, sealing, and other applications, ensuring a steady and controlled supply of shrink film.
11. Film Separator
A device used to separate centerfold shrink film before sealing and shrinking, preventing issues during the sealing process.
12. I Bar Sealer
A machine consisting of one heated side used to seal off and enclose products within a flexible plastic film, commonly used for smaller-scale operations.
13. Impulse Sealer
A smaller I Bar sealer often used for low production sealing, providing a cost-effective solution for smaller packaging needs.
14. Infrared Shrink Tunnel
A form of shrink tunnel often consisting of multiple infrared heating tubes used to heat the inside of the tunnel, ensuring efficient and consistent heat distribution.
15. L Bar Sealer
A machine consisting of two heated sides used to seal off and enclose products within a flexible plastic film, suitable for various packaging applications.
16. Magnetic Hold
A locking mechanism using magnets to hold down a sealing bar until a seal is completed, ensuring precision and consistency in the sealing process.
17. Mesh Belt
A gridded wire belt overlay placed on conveyor roller rods to prevent smaller products from slipping between individual rollers, facilitating the smooth movement of products through the conveyor system.
18. Micro Knife/Band Ribbon
A newer form of a sealing element found below sealing bars used to replace sealing wires. Band ribbons are often attached to the mainframe of the machine below the sealing bar, offering enhanced durability and efficiency in sealing and cutting.
19. Pinwheel Perforator
A wheel-shaped object with sharp points often placed close to the film rack to insert small holes into shrink film. The small holes allow air to escape the sealed package when heat is applied, preventing air pockets.
20. Power Film Unwind
A motorized sealer feature designed to easily unwind film from the carriage for easier use, ensuring efficient handling of shrink film.
21. Recirculating Shrink Tunnel
A form of shrink tunnel using fans to blow heat within the shrink tunnel continuously, enhancing the overall efficiency of the shrink-wrapping process.
22. Roller Rods
Rotating rods often Teflon coated placed on a conveyor chain to transport products through a shrink tunnel, providing a reliable and smooth conveyance.
23. Seal Time
A specified time set to complete a seal on flexible plastic materials, crucial for achieving consistent and high-quality seals.
24. Sealing Bar
The top bar on an L Bar sealer or I bar sealer, lowered down to create a seal on flexible plastic film, forming the foundational element of the sealing process.
25. Sealing Wire
A heated wire element found on the sealing bar, used to apply heat to create a seal on flexible plastic. Sealing wires are available in flat and round wires, each serving specific sealing purposes.
26. Shrink Chamber
A fully enclosed seal and shrink wrapping machine that fills with hot air for a specified time after a completed seal, ensuring thorough and efficient shrinkage of the film.
27. Shrink Time
A specified time set to apply heat to a shrink film to obtain the proper shrink rate, crucial for achieving the desired packaging outcome.
28. Shrink Tunnel
A heating element commonly used with shrink wrapping, consisting of a conveyor moving products through a heated area to shrink film, playing a pivotal role in the shrink-wrapping process.
29. Single Wound Shrink Film
A flat shrink film placed on a roll, providing a straightforward and easily dispensed form for packaging.
30. Steam Shrink Tunnel
A form of shrink tunnel using steam to heat the tunnel interior, offering an alternative heat source for the shrink-wrapping process.
31. Teflon Tape
A PTFE extruded tape with a chemical-resistant surface, placed over sealing wires and bumpers to reduce film build-up directly on the sealing wire, enhancing the longevity and efficiency of the sealing process.
32. Transit Channel
A ceramic channel used to hold band ribbons in place, ensuring stability and proper functioning of the band ribbon in the sealing process.
