Tekni-Films SBC 240, a new super barrier-coated (SBC) thermoformable film for pharmaceutical blister packs, has been developed by Tekni-Films.
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.
As such, SBC 240 is claimed to offer 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 F – which helps meet specific production speed preferences.
In addition to its 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 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 said to be ideal for applications such as pharmaceuticals, nutraceuticals, probiotics and other related products.
Tekni-Films, a Tekni-Plex business, is a supplier of thermoformable blister barrier films, flexible films, lidding foils and pouch materials for pharmaceutical, medical, diagnostic health and personal care products.
