Thermoplastic films for packaging having a super-hydrophobic sealant surface (0), flexible packages made therefrom and their use in packaging products, especially food products are described. These packages are characterized by optimal performances, especially in terms of seal strength, recovery of the packaged product and prevention of drip formation.

The invention provides a packaging comprising opposing and spaced apart front and back panels separated by side panels extending therebetween, wherein a marginal sealing region of each end of the front and back panels is sealed together and wherein at least a portion of an edge of at least one end of the side panels is not connected to the marginal sealed regions of the front and back panels, and, wherein the panels are formed from cartonboard.

A tissue paper package not prone to losing shape. Film-packaged tissue paper comprising a pop-up type substantially cuboid bundle of tissue paper packaged with a flexible resin packaging film, and characterized in that air vents for providing communication between the inside and the outside of the package are formed at positions on the packaging film facing short-side surfaces of the bundle of tissue paper where no folded edges are arranged.

A film-packaged tissue in which wrinkles or twisting is less likely to occur in tissue paper stored in the film package. A bundle of pop-up type tissue paper is film-packaged by a resin packaging film. The inner circumferential length of the packaging film in a short direction of the bundle is 91 to 97% of a theoretical outer circumferential length in the short direction of the bundle, and the compression characteristic (RC) of the film-packaged tissue by KES measurement at a longitudinal center of a bundle upper surface is 45 to 60%.

The present invention relates to multilayer packaging films having an outer super-hydrophobic anti-abuse surface and to bags made therefrom, with the super-hydrophobic surface as the outermost surface. The packages made from the films of the invention do not get wet during post-packaging treatments requiring hot-water or steam such as shrinking, sterilization or pasteurization (FIG. 7A). At the exit of the shrinking apparatus, or of the sterilization or pasteurization apparatus, the packages do not need any final drying and can be directly placed into the cardboard boxes for shipment, with evident advantages of time and energy savings.

According to an aspect of the present invention, there is provided a package comprising: a sheet of flexible film material folded along a longitudinal direction to bring edges of the sheet together, said edges being sealed to form a longitudinal rear seam; a first end of the folded sheet is sealed by a first end seam, and a second end of the folded sheet is sealed by a second end seam to form a space for items, wherein said space is defined by said sealed ends and a side wall formed of the folded sheet; an opening initiation point in one of the end seams, said initiation point configured to provide a point for initiating tearing of the flexible film material to form an opening; a tear control element configured to guide tearing initiated from the initiation point along a longitudinal direction, from the first end seam to the second end seam and across the sidewall, upon applying a tearing force.
