Definitions

  • the invention relates to an improved process for the manufacture of sachets in a plurality of lanes in a form fill and seal (FFS) machine.
  • FFS form fill and seal
  • Sachets have been used for packing various types of products like creams, powders, liquids, tablets, noodles, granules, and pastes in various fields of technology. Sachets enable packing and selling of these products in small quantities compared to conventional packaging like bottles and jars. The sachets also enable convenient use during travel when smaller quantities in so-called ⁇ unit-dose' amounts can be carried without spillage. The products are dispensed by tearing the sachets and using the product for a single use after which the sachet packing is discarded.
  • the sachets are also very convenient for sale to new consumers who do not want to spend a lot of money trying out new products since the cost of the product in a sachet is much lower as compared to those sold in conventional units like a bottle or a jar. Thus a consumer who wants to try a new product need not spend a lot of money buying a large quantity of the product in the conventional bottle or jar.
  • the sachet packaging has also enabled consumers in the developing countries who do not have a lot of spare money, to purchase these products in small quantities in the sachet packaging.
  • Sachets are manufactured in machines where several sachets are formed and filled, each sachet connected to the next in a long string. This string of sachets can then be hung at the point of sale for high visibility. Each sachet in the lane is separated by perforations which enable easy tearing of the desired number of sachets from the string based on the customers demand. Recently, multiple lanes of sachets are also available which is displayed at the point of sale in the so called curtain format . The sachets in the curtain format are separated by perforations along the two longitudinal edges as well as the top and bottom of the sachet.
  • Sachets have been manufactured in a variety of materials based on the product to be packaged. Products like tea and coffee have been packaged in porous paper which enable infusion of the tea/coffee when the sachet is dipped in hot water. For most other products in the detergent and cosmetic industry, the sachets have been prepared from synthetic polymers.
  • the development of automatic machines like the form fill and seal (FFS) machine has enabled very high production rates of sachets. These machines form the sachets from two films which define the front surface and the rear surface, usually by heat sealing three edges to form a three edged pocket, followed by filling of the product in the said pocket, after which the fourth edge is sealed.
  • the sachets may be cut into single lanes or may be sold in the curtain format. Perforations are provided where required along the seals to enable easy separation by tearing one or more sachets from the rest of the strip or curtain.
  • EP 0378027 (Modern Packaging, 1990) describes a process for the manufacture of individual sachets each containing a product which process comprises the operations of (a) preprinting two films, which form the opposite sides of the sachets and are heat-sealable on the inner sides, with the desired inscriptions on the outer side (b) bringing the two films substantially close together for depositing a product (c) partially heat-sealing the sachet around the deposited area to form the sachet in a first sealing station (d) the sachet thus profiled is displaced towards a second sealing station (e) completing the sealing in a second sealing station (f) stamping out the sachet from the web in a cut ⁇ out station using a die and a mould corresponding to the profile desired for the sachet (g) the sachets thus cut out are collected while the web cut is evacuated (h) the sachet being cut out along the heat-sealed cheek of the web characterized in
  • WO0123271 (Cryovac, 2001) describes a pouch, and a process and an apparatus for the preparation of said pouch, the pouch comprising a first lateral edge and a second lateral edge, each of the first and second lateral edges comprising a concave surface and a convex surface, wherein the concave surface of the first lateral edge is substantially opposite the convex surface of the second lateral edge and the convex surface of the first lateral edge is substantially opposite the concave surface of the second lateral edge.
  • WOOl/23271 also describes pouches and process to prepare them which essentially requires the pouches to be cut into single strips -thereby not providing for the curtain format.
  • the pouches of this prior art further suffers from the disadvantage that the curved shape of one lateral edge has to be complementary to the shape on the other lateral edge thereby restricting the flexibility of providing various shapes which may be desired to be given to the packaging.
  • non-linear profile on the edge of the sachet is a curved profile.
  • non-linear profiles are on the longitudinal edges of the sachets.
  • FIG.l is a schematic of one of the embodiments of the process for manufacturing the sachets in the plurality of lanes in an FFS machine.
  • FIG. 2 is a front schematic view of a portion of the sachet in a curtain format where every longitudinal edge has one cut-out portion covering about 95% of the length of the longitudinal edge.
  • FIG. 3 is a front schematic view of a portion of another sachet assembly in a curtain format where every longitudinal edge has two cut-out portions covering about 85% of the length of the longitudinal edge.
  • the invention provides for a process for the manufacture of sachets in a plurality of lanes in the form fill and seal
  • FFS field-programmable gate array
  • the sachets of the invention can be manufactured in either the horizontal or the vertical FFS machine, it is preferred that it is manufactured in the vertical FFS machine.
  • the invention concerns process for the manufacture of sachets having at least one edge which comprises a non ⁇ linear portion.
  • ⁇ non-linear' for the purpose of this invention, is meant profiles which are not definable by a single straight line.
  • x non-linear' includes angled bends formed when two or more lines are joined to each other, curves of any shape and combinations thereof. It is preferred that the non-linear profiles are curved profiles.
  • the non-linear edges could be on either the longitudinal edges or the transverse edges of the sachets, although the non-linear edges are preferably on the longitudinal edges.
  • edges By the term 'longitudinal edges' is meant the edges defined by sealing the films in the longitudinal direction of the films i.e the film in the lengthwise direction.
  • the longitudinal edges are sometimes referred to as the lateral edges of the sachets e.g the left lateral edge and the right lateral edge.
  • the transverse edges of the sachets are edges in the direction perpendicular to the longitudinal edges i.e as it is sealed breadthwise on the film.
  • the transverse edges usually define the top and the bottom of the sachet .
  • the edges of the sachets comprise non-linear profiles extending over atleast 10% percent of the length of the edge, more preferably at least 30%, further more preferably at least 60% and most preferably at least 90%of the length of the edge.
  • the profiled edges appear as cut out portion when the sachets are manufactured in a plurality of lanes in the FFS machines.
  • the profiles of the edges could be formed from one or more cut out portions.
  • the number of lanes of sachets which can be produced in an FFS machine is dictated by the width of the sachet, it is preferred that the number of lanes are between two and sixteen, more preferably between 4 and 12 and most preferably between six and twelve. It is also possible to have a profile on one edge of the sachet and a different profile on another edge.
  • polymer materials may be used in the process of the invention.

  • metallised PET foil or polyethylenes.
  • laminates of more than one material are used for improved physical, thermal, mechanical and printiability properties. It is particularly preferred that the two surfaces which are brought in contact for forming the inside surface of the sachet are heat- sealable.
  • the view of Figure -1 depicts an embodiment of the FFS machine for forming the sachets as per the invention.
  • the sachets in the FFS machine are prepared from two films or webs which form the front (9) and the rear (10) surface of the sachet.
