Flexible Foils

Foils provide barrier protection and tamper evidence.

Foil Laminations
Heat-seal-coated foil laminations offer medical device manufacturers a solution for devices requiring puncture- resistant barrier packaging and visual assurance of seal integrity. The foil laminations are coated with adhesives formulated to peel smoothly yet be resistant to high-altitude creep, low-temperature flex, and stress creep caused by impact and vibration during shipping and handling. Foil laminations offer puncture resistance and light, oxygen, and moisture barrier properties for sensitive products. They are available as peelable or tear-open pouches, die-cut lidding, and printed rollstock. The foils are sealable to a variety of foils and high-barrier films, PETG, PVC, PP, HDPe, and other rigid tray materials and are compatible with radiation and steam sterilization processes.

Flexible Packaging
A company provides many combinations of materials with varying MVTRs. These include clear as well as metalized materials. Stock barrier materials include laminations with 0.00035-mil and 1-mil foils, which are available as rollstock, printed or plain, or they can be converted into peel pouches or lids. Both peelable and nonpeelable materials are available. Another packaging alternative is a header pouch with a removable Tyvek header strip for EtO sterilized devices that require a barrier. Compartmented folded pouches made of high-barrier structures are also included in the product offering. Most products are available as individual pouches or on a roll. Custom structures can be developed for specific requirements or stock material can be used. Beacon Converters, Saddle Brook, NJ; 201/797-2600; www.beaconconverters.com.

Cold-Form Foil
For blistered products requiring the highest barrier properties, a company's cold-form foil offers maximum protection against moisture, air, and light. Used to provide cold-form cavities into which product is inserted and then covered with a suitable lidding foil, the cold-form foil possesses high tension-at-break and elongation-at-break mechanical properties, and maintains high dimensional stability after cold forming. The specifically adapted performance of each layer makes the foil extremely cold-formable, allowing for various three-dimensional draw ratios, including applications with extreme deep-draw requirements. The foil is also well suited for high-speed processing and registered printing and can be used on blister lines with a cold-forming station.
