Definitions

  • the present invention relates to a packaging for a food product and particularly for performance bars as well as performance bars enclosed in such a packaging.
  • Energy bars or protein bars are considered illustrative representatives of such performance bars .
  • Packages for food products are well known from the prior art and primarily serve the purpose of conserving the freshness and taste of the packed product. Therefore, the packages are often sealed and thus impermeable to moisture and gas.
  • An additional purpose of the package is to provide consumer information such as the name of the product and the contained ingredients thereof.
  • Such food products can be wrapped by means of flow wrapping as described in WO 2006/100084 Al such that a longitudinal sealing seam and two transversal sealing seams can be provided at the side portions of the product to effectively seal the packaging.
  • a longitudinal sealing seam and two transversal sealing seams can be provided at the side portions of the product to effectively seal the packaging.
  • two peripheral strips which have different widths are folded on top of each other on the external side of the packaging. The folded strips are then adhered to the external side of the packaging by means of a cold-bonding agent.
  • EP 1 288 139 Al relates to a package for generally block- shaped food products, wherein one of the side portions of the packaging comprises two flap portions formed at a backside of the food product which are free of adhesive. According to this embodiment, accessibility of the food product is enhanced.
  • Performance bars such as e.g. energy bars, protein bars etc.
  • Performance bars are meant to be consumed in completely different conditions than e.g. chocolate bars.
  • Performance bars are often consumed during training or competitions .
  • the packaging thereof has to be opened with wet or sweaty hands, during running, during cycling etc.
  • the packaging sometimes has to be opened with a single hand and/or using the mouth (lips, teeth,...) .
  • opening means for the packaging of such a food product are sought-after which further enhance the accessibility of the product and enable an intuitive opening of the packaging.
  • the present invention aims at providing a bigger surface for consumer information at a front or rear side of the packaging.
  • the opening of the packaging should maintain the packaging as one coherent piece in order to avoid littering of smaller pieces of the packaging.
  • the present invention seeks to address the above-described problems.
  • the invention also aims at other objects and particularly the solution of other problems as will appear in the rest of the present description.
  • the invention proposes a flow wrapped packaging for a food product such as e.g. a performance bar.
  • the packaging is made from a flexible material.
  • the packaging is folded around the food product at one side and sealed on the remaining side portions of the packaging. Thereby two adjacent flap portions extend at at least one of the side portions of the packaging.
  • the flap portions are connected at their end adjacent to the associated sealed side portion.
  • the flap portions extend freely and linearly thereof essentially in the main plane of the food product.
  • the flap portions are essentially not folded.
  • the lateral side portions of the packaging are not sealed to their full length such that the flap portions (5a, 5b) are not joined together at said lateral side portions (Bl, B2) .
  • the two adjacent flap portions (5a, 5b) comprise grip elements (6a, 6b) provided at an inner or outer surface (7a, 7b) of the flap portions (5a, 5b) . Accordingly, since the flap portions extend linearly away the main surfaces of the packaging, the communication area provided at the front and rear surface of the packaging is enlarged.
  • a food product can be effectively protected against environmental influences such as humidity or gas in order to enable a long stability upon storage of the food product.
  • the opening characteristic of the packaging is enhanced due to the two free flap portions protruding from the longitudinal sealed side portion of the packaging. Hence, a consumer may easily open the packaging by tearing apart the two free adjacent flap portions.
  • the packaging material is preferably made from plastics, paper or metal foil or compound foils thereof known in the field of packaging of food products.
  • the free adjacent flap portions are preferably provided at one of the longitudinal side portions of the packaging.
  • the free flap portions may as well be provided at any edge portion of the food product to enhance accessibility thereof.
  • the flap portions are preferably protruding from the side portion of the packaging to different extents.
  • an intuitive opening of the packaging is enabled since the two overlapping flap portions effectively suggest the opening mechanism of the packaging to a consumer.
  • the flap portion which protrudes to a greater extent from the side portion of the packaging is located at a rear surface of the packaging.
  • the opening mechanism is indicated to a customer looking at the front surface of the food product, since both overlapping flap portions are visible.
  • the sealing portions formed at the side portions adjacent to the side portions which extends two free adjacent flap portions are designed such that they do not extend over the flap portions. Hence, the flap portions are freely moveable with respect to each other along their whole width. Accordingly, a consumer may tear apart the flap portions at any position along the side portion of the packaging at which the flap portions are located.
  • the two adjacent flap portions preferably comprise grip enhancing elements provided at an inner and/or outer surface of the flap portions. Accordingly, the handling of the flap portions is improved such that the flap portions can be grabbed and torn apart in order to open the packaging.
  • the grip elements may be formed as an integral part of the flap portions of the packaging.
  • the grip elements may be additional means connected to the flap portions of the packaging.
  • the grip elements comprise a surface modulation such as e.g. a pattern of embossments.
  • the grip elements may comprise a pattern of holes or apertures.
  • grip elements may be any other physical or chemical means, added or present as an integral part of the flap portions, increasing the friction between the two flap portions such that the flap portions are prevented from sticking to one another.
  • grip elements may be designed equal or different for each of the two adjacent flap portions.
  • Grip elements may be present on one or both flap portions .
  • an attraction between the two flap portions such as an electrostatic attraction or an attraction due to moisture present between the flap portions can effectively be prevented.
  • the easy opening of the packaging is maintained even if the packaging is subjected to environmental influences thereon such as moisture or electrostatic charge.
  • the grip elements may as well comprise material adhered onto the flap portions.
  • a material may be for example a specific coating applied to the flap portions in order to further enhance the handling of the flap portions.
  • the coating may be applied to one or both of the flap portions.
  • sealing of the packaging is obtained by a sealing film which is used on its own or added to other layers of packaging material.
  • the sealing film is preferably a heat-sealable peelable film comprising thermoplastic material such as polyolefin. Accordingly, at least to a portion of the packaging thermoplastic material is applied in order to enable a sealing of at least three side portions of the packaging.
  • the heat-sealable film is a co- extruded film.
  • the co-extruded film comprises a bulk layer of relatively inexpensive resin material and a thinner peelable sealant layer.
  • the bulk layer provides a cushioning effect when sealing and gives the film a body. This has the advantage that the thickness of the peelable film can be adjusted to meet the particular packaging needs.
  • the co-extruded film can then be laminated to other layers of the packaging material. Accordingly, the barrier and/or printing properties can be enhanced.
  • the co-extruded heat-sealable film may be designed to enable an adhesive or cohesive peel thereof. Thereby, depending on the choice of the used resin materials, durability and barrier properties of the sealing are enhanced.
  • a heat-sealable coating or a cold seal adhesive e.g. on acrylic basis may be applied in order to enable effective sealing of the packaging.
  • the peelable film used for sealing the packaging is peeled off from one side of the packaging to be sealed by the film and thus, the packaging is opened without destroying the packaging material.
  • additional reclosing means may be provided for enable a reclosing of the packaging. Accordingly, a user may open and thus, reclose the packaging. Thereby, the number of possible opening and reclosing operations depends on the strength and durability of said reclosing means. It has been found that for products with an adhesive surface a re-closable effect can advantageously be obtained without reclosing means. The package can simply be reclosed due to the adhering between the product and the packaging material.
  • the packaging is preferably applied to the food product by means of flow-wrapping. Hence, fast and convenient packaging of the food product is obtained.
  • the invention proposes a method for packing a food product by means of a packaging according to any of the preceding claims, said method comprising the steps of: placing the food product on an inner surface of the packaging; folding the packaging around a longitudinal edge of the food product to enclose the food product such that two overlapping flaps are formed at an opposite longitudinal edge of the food product, wherein the overlapping flaps protrude from said opposite longitudinal edge to different extents; and sealing side portions of the packaging such that the flaps formed at the longitudinal side portion of the packaging are sealed together at an axis parallel to a longitudinal edge of the food product and are freely movably with respect to each other. Accordingly, it is possible to effectively wrap and seal a food product such that an enhanced opening mechanism is formed at a longitudinal side portion of the packaging.
  • the method preferably comprises the step of sealing two opposite lateral side portions of the packaging at an axis parallel to a lateral edge of the food product such that flaps formed at the longitudinal edge of the food product are not joined together.
  • the two adjacent flap portions formed at a longitudinal side portion of the packaging are freely moveable with respect to each other. Accordingly, a consumer may grab the two free flap portions and open the packaging by tearing the flap portions and thus the packaging material apart.
  • the flap portions preferably extend freely from 5 to 35 mm, more preferable from 10 to 30mm. If the free flap portions are of different length the difference. It is preferred that the difference in the free length extended is at least between 2 to 5mm.
  • packaging and the method for packing according to the present invention are not limited to be applied to block-shaped food products but can be applied to any food product or food products of different shape such as energy bars, chocolate bars, cereals, powders, etc. Moreover, more than one food products may be packed within the packaging according to the present invention.
