Latest Patents

One of Voisin's latest patents is for a heat-sealable composite polymeric film. This invention features a sealed container designed for foodstuffs or beverages, incorporating a lid made from a heat-sealable composite film. The film consists of a polymeric substrate layer with a primer layer containing PVdC on one surface, and a heat-sealable polymeric layer that is extrusion coated on the primer layer. The heat-sealable polymeric layer is notably thin, measuring 12 µm thick or less, and includes a copolymer with specific repeating monomeric units.

Another significant patent by Voisin is for a self-venting polymeric film. This breathable, heat-sealable composite film comprises a perforated polymeric substrate layer and an unperforated barrier layer. The barrier layer is designed to be no thicker than 12 µm, while the perforated substrate layer has a degree of perforation ranging from 0.1 to 78%. This innovative film is particularly suitable for packaging freshly cut plants, such as flowers, vegetables, fruits, and salads.
