Definitions

  • Continuous band of reinforced plasticized paper for manufacturing bags for horticultural products or the like.
  • the object of the present invention is a continuous band of plasticized paper reinforced with a plastic material being approximately reticular shaped, which is specially designed for the subsequent manufacture of bags for horticultural products or the like by attaching its longitudinal edges to become a continuous tube and by transversal welding and cuts parallel thereto to obtain unitary bags.
  • This novel continuous band thanks to the arrangement of windows and the plastic reinforcing material, provides a better performance in welding processes, a folding which does not damage the continuous band and an easy opening of the bags and which does not damage bag integrity.
  • the marketing of horticultural products is done using bags made of different materials, which need to have holes and windows on their surface for aeration of the product and continuous surfaces on which to include for instance by printing, the information required by the various regulations or advertising the manufacturer may want to include.
  • the bags can be made of continuous bands intended to close over themselves by attaching their longitudinal edges to form a continuous tube which can be fragmented into a plurality of sectors corresponding to the respective unitary bags by transversal joints and cuts likewise transversal.
  • the bands may be made of a single material or by joining various layers of materials.
  • the object of the present invention is to use paper in its manufacture to reduce cost and weight, strengthen said paper, so that it can withstand the weight of bagged products, and improve its behaviour in the processes of conventional welding by folding a second sheet of plastic material being reticular and finally, prevent paper breakage when folded to form the bag by a suitable arrangement of windows in the critical folding areas.
  • Another object is to offer the consumer an opening system that does not require sharp objects and containing products does not affect the functionality of the bag, because the bag does not need to be opened at its ends.
  • the continuous band of reinforced plasticized paper for manufacturing bags for horticultural products or the like, object of the present invention comprises a first continuous sheet of plasticized paper in at least a first side that is intended to be the inside of the bags, the width of said first continuous sheet of paper being the same as the width of the continuous band and a second continuous sheet of plastic material whose width is the same as the width of the continuous band and attached to the entire first side of the first continuous sheet of paper by gluing, heat sealing, ultrasound or similar procedure, the shape of said second continuous sheet being approximately reticular; in each of the sectors corresponding to the unitary bags of the first continuous sheet of paper is conveniently arranged:
  • FIG. 1 and 2 show a preferred embodiment of the continuous band (1) object of the present description.
  • the continuous band (1) comprises a first continuous paper sheet (2) plasticized on both sides and a second continuous sheet (3) of plastic material, preferably extruded or laminated polyethylene, reticular shaped.
  • two first punched windows (5) are arranged, the said first windows are located in the area of the continuous band intended to implement the upper transversal joint and the lower transversal joint of the adjacent sector, one of the first referred windows being located in the first fold (10) and another first window being located in the second fold (11).
  • the first and second fold are carried out during the attachment process of the longitudinal edges of the continuous band, together with additional folds so that the bags present lateral sides when extended or filled. It is in the areas of the continuous band where the transversal joints and the folds converge where there is a risk of breakage of the continuous paper sheet, which is avoided by the first windows.
  • One or more ventilation windows (6) are arranged in the continuous paper sheet for product aeration and to allow the consumer to see, for example, the condition of the packaged product. Through these ventilation windows one can easily tear the second continuous sheet to access the inside of the bag and not break the band preventing the product from spilling.
  • the use of the second continuous sheet has two primary objectives, the first is to increase the mechanical strength of paper and the second is to improve the performance of the first sheet of paper in attachment procedures such as heat sealing, ultrasound or similar methods.
  • reinforcements (12) of plastic material are arranged between the first continuous sheet of paper and the second continuous sheet which may be located either in one or in all of the places described below, such as in the areas intended for the longitudinal and transversal joints at the edges of the first windows, at the edges of the second windows, said reinforcements are arranged between the first continuous sheet and the second continuous sheet or at the edges of the ventilation windows.
  • the first transversal joint can form a flap having two or more punched holes (13) acting as a handle to facilitate manipulation of the product and its promotion in the retail locations.
  • the upper and lower transversal joints can be made by gluing, heat sealing, ultrasound or other similar procedure.
