Understanding the machinery supply chain
How does it work?
Converters purchase oriented film in master rolls, print and convert into a tube for manual or automatic application & shrinkage. Shrink Sleeves are dynamic labels whose converting process directly affects the finished product. Thus, top converters that process shrink sleeve, work very closely with the end customer and the application machinery supplier to ensure successful implementation. Karlville's unique approach and leading business model to supply converting as well as application machines, allows our technical team to be most prepare to support our ever growing customer base.
Oriented Film Supply Chain
The choice of substrate is a key part of the shrink sleeve process. Each film has its own shrink curve which is tied to the printing dimensions of the art. Contact us to learn more about the different types of film (PET, PETG, PO, OPS…) and recommended suppliers.

In order to ship directly off your seamer, all print defects must be doctored prior to seaming. This can be done on a slitter or an inspection machine.Visit Inspection
The printed oriented shrink sleeve film is folded and chemically seamed (welded) with a solvent. Seaming Solvents, a Karlville partner, offers a wide range of chemical solutions for various film substrates. Karlville offers the most complete and advance seamer produce line in the market today.Visit Seaming
For inspecting for open seams, splices and stuck seams, the inspection process is critical for a shrink sleeve converter. If you are inspecting partially or in full your production, a well configured inspection machine may help you to increase throughput.Visit Inspection

Slitting accuracy & quality is critical step in shrink sleeves converting as borders may be damaged with heat with improper knifes. Savvy converters integrate smart workflow to slitter.
LasX Lasers, integrated to our unwinds, produce continuous and traverse perforations for recycling and pre perforated films for advance converting. These laser are integrated to our non stop turret seamers.
