Films Offer Visual Clarity and Barrier Protection

Films offer strength as well as oxygen, moisture, and light protection for the safe packaging of drugs and devices.

High-performance films are available for peelable, formable, and high-barrier applications. The company offers its Allegro peelable sealant films, Forte weld sealant/overwrap films, ClearFoil high-barrier transparent films, and FlexForm economical forming web systems. These materials are suitable for all sterilization methods and are available in rollstock forms, premade pouches, or die-cut lids, either printed or unprinted.

A barrier material for blister packs provides a high moisture barrier and composite adhesion. Perlalux Starflex replaces traditional LDPE laminate with a thermoelast coating to provide a high level of security against delamination. Starflex is free of solvents and can be recycled easily. The material requires a relatively low prewarming temperature, which reduces energy costs. Starflex may be used as a cost-effective alternative to Aclar, according to the company.

Medical packaging film is designed to help provide a more cost-effective package. PerfecFlex CPT is the formable version of the company's CPT (clean peel transfer) technology. Device manufacturers can use uncoated Tyvek, a cost-effective top web, on form-fill-seal equipment with acceptable packaging system performance. Formable CPT allows for sealing in the conventional manner over a wide temperature range. A consistent peel with good white transfer is achieved without fiber tear. Perfecseal Inc., a Bemis Co., Philadelphia, PA.

Extrusion-coated and laminated films and foils meet exacting regulatory specifications and can meet the demands for protection and quality. The Integra Flex line contains tough, clear Surlyn packaging resin, which provides package integrity; high resistance to punctures, pinholes, and abrasion; and notable machinability and hot-tack strength at a wide range of temperatures. The company aims to provide cost-effective structures that meet high safety and performance standards. DuPont, Wilmington, DE.
