Tyvek Printing for MEDICAL Packaging
Tyvek has been used for more than 40 years in a vast variety of roles. Perhaps most importantly, Tyvek is integral in medical device sterilization.
As the FDA has begun implementing UDI requirements across the medical device industry, the ThermaPrint 64 has solidified its role in Tyvek pouch and lid printing. Near-edge thermal transfer technology allows crisp 1D and 2D barcodes as well as logos, text, and graphics.Request a Quote
What is Tyvek?
Tyvek is a registered trademark of Du Pont, who first discovered the material in 1955. It was trademarked in 1965, and released for general use two years later. Since then is has become ubiquitous in many industries, and is the go-to material for sterile packaging.
Though superficially similar to paper, Tyvek is completely synthetic. It consists of spunbound Olefin fibers, each between 0.5-10 µm in width, which are bonded together using heat and pressure.
Tyvek has many useful properties. It is extremely lightweight, and yet also tough. It resists tearing very well, and yet can be cut easily with scissors. It is not flammable, has good opacity, and a neutral PH level. Perhaps most usefully, it is breathable, being permeable to water vapor but not liquid water.
Tyvek is used in a vast variety of roles, including HAZMAT suits and wristbands for festivals, and is a familiar sight protecting buildings for adverse weather.
One of its most common uses, though, is in medical packaging. Critically, Tyvek can withstand the conditions used to sterilize medical equipment, meaning that Tyvek packaging is able to keep this equipment sterile for long periods.Request a Quote
What to Look For in a Tyvek Printer for Packaging
Choosing a Tyvek printer for packaging depends on your own requirements, and the types of orders that you are processing.
However, no matter the type of printing you are doing, some things should always be taken into account when choosing a Tyvek printer:
One of the most important considerations is speed. Print orders for the health-care sector are often of very high volume, and so a printing speed of at least 5 inches/second is a must. In addition, some Tyvek printers now have a slew capability, allowing them to quickly skip over non-printed sections of the substrate, greatly improving overall speed.
Print quality should also be a major consideration.
Often, packaging and labels require that very small writing be reproduced precisely, and this is of special concern in the health-care sector. Nowadays, the best thermal Tyvek printers are able to print at up to 300 DPI, which is more than sufficient for these purposes.
If you are dealing with extremely large orders, an automated and motorized sorting module is also extremely useful. In many cases, an order for Tyvek packaging will contain several varying types or sizes of package, and a motorized sorter means that each type will be automatically stacked in the correct pile.
Another consideration should be the adaptability of the printer. A good Tyvek printer will be able to deal with a wide range of thicknesses, offer several different fonts, and even cut packaging into a variety of formats and shapes.
The cost of consumables should also be considered. Whilst most Tyvek printers use thermal printing techniques, some now come with advanced features that significantly improve efficiency, meaning that consumables will last longer.
Last but not least, of course, the ruggedness of the printer should be assessed. Tyvek printers, like a lot of industrial printers, often need to work reliably in quite difficult environments, and the printer should be able to deal with heat, dust, and other complications.Request a Quote
