A new super barrier-coated (SBC) thermoformable film for pharmaceutical blister packs is being launched by Tekni-Films, a Tekni-Plex business.
Tekni-Films SBC 240 is being positioned as a performance and improved-cost alternative for 4- and 6-mil PCTFE and cold formed foil in thermoformable blister applications. The triplex structure is ideal for applications such as pharmaceuticals, nutraceuticals, probiotics and other related products.
In addition to its desirable clear properties, SBC 240 doesn’t require stiffening ribs, which can be used to improve the ability of PCTFE to lie flat, nor the oversized blister wells created by cold forming. This means that pharmaceutical companies can use a smaller blister card to contain the same number of tablets or capsules, or increase the count on a same-sized card. The end result is material cost savings all the way through the packaging process, including cartons and cases, as well as improved production efficiencies.
SBC 240 offers ultra-high moisture and oxygen barrier properties to protect products susceptible to degradation. It also has a wider processing window than PCTFE—as much as 20 degrees Fahrenheit—which helps meet specific production speed preferences.
SBC 240 is created by applying a “next generation” high-barrier variant of polyvinylidene chloride (PVdC) coating to a film structure made from layers of polyethylene. Multiple layers can be applied to create different coating thickness weights. As coating weight increases, so do the barrier attributes.
This latest grade is just one more example of Tekni-Film’s robust SBC thermoformable film capabilities. The company also offers 120-, 150-, 180- and 210-gram coating thicknesses, as well as other custom solutions.
