Cocoon Wrapping Helps Protect DuPontTyvek® in Transit

Traditionally, DuPontTyvek® medical packaging styles 1073B and 1059B have been wrapped with a cardboard header before being shipped from our manufacturing facility in Richmond, Va. DuPontTyvek® 2FS, on the other hand, has always been cocoon wrapped

  • totally enclosed without headers before being

shipped from our manufacturing facility in Luxembourg.

Based on overwhelmingly positive feedback from global customers of Tyvek® 2FS, together with our commitment to continuous improvement, the DuPont Medical Packaging Team undertook a project to extend the use of cocoon wrapping to all styles of Tyvek® medical packaging.

Using the technology in place at the Luxembourg facility as a model, the team selected equipment and developed

procedures to handle and automatically wrap individual rolls of Tyvek® medical packaging so that they are totally encased in tough polyethylene stretch film without the use of cardboard headers. Eliminating the cardboard headers meant the elimination of a potential source of cellulose contamination and the prevention of a bellows effectduring shipment that could cause foreign debris contamination.

Two wrapping stations were set up in series: an axial wrapper that provides 100% film coverage and a radial wrapper that seals the rolls barrel with an outer layer of film. The equipment uses state-of-the-art controls to ensure smooth, efficient and consistent process application.

In ophthalmic surgery, the risk of cross-infection is extremely high,said Hohl. The only functional way to increase safety for the patient is by using single-use products. At Medicel, we are committed to not only making disposable products in the same quality as expensive reusable instruments, but to presenting them in a manner that makes the job of the surgical staff easier and ensures the sterility of the product. We know that packaging is a key to this objective and Tyvek® has proven to be a critical component for success,Hohl explained.

The FIRST LINEset required the design of a new injection molded tray with various compartments to hold all of the disposable accessories. The tray and the pre- printed and cutting lids are made by MEDIPACK. The Tyvek® is coated by Perfecseal.
