Definitions
- the present invention relates to a packaging method for commercial sheet food.
- sheet-like water-in-oil emulsified yarns and products sheet margarine
- sheet-like oil-in-water emulsified yarns and products sheet-like flower paste
- sheet-like chocolate sheet-like chocolate.
- Sheet margarine is mainly used for the production of pies, Danish pastries, croissants, etc.!
- the sheet margarine has a size of one sheet of margarine of 20 cm to 40 cm on a side, a thickness of about 0.5 cm to several cm, a weight of usually 500 g to 2500 g, and a level of about lOKg.
- a size of one sheet of margarine of 20 cm to 40 cm on a side, a thickness of about 0.5 cm to several cm, a weight of usually 500 g to 2500 g, and a level of about lOKg.
- Patent Document 1 it is well known that a sheet-shaped margarine is packaged horizontally, and such a product has been released before, but it is necessary to break the packaging.
- a major food manufacturer that opens more than 10,000 bags a day will force harsh manual opening.
- One way to facilitate opening is to place a notch on one side of the bag and tear it into a tape (Patent Document 2). Since it may cause a problem of foreign matter contamination, it does not become widespread and it seems that the current method has been settled.
- the method as described in Patent Document 1 is disadvantageous for mass processing because the content required for the contents is limited by the dividing device, and the processing speed is limited, and the cutting of the product is not clean.
- the cardboard box When using sheet foods that are currently popular, the cardboard box is opened, the laminated sheet food is taken out together with the film, and the film is peeled off. The cardboard box is opened until the cardboard box is opened. Paper dust or the like may adhere to the product from the open end of the sheet and may cause contamination problems. In addition, there is a problem that the color changes when the side of the sheet-like food is dried.
- Patent Document 3 discloses a simple openable bag body made of a laminated film cover in which a base material layer and an easily peelable sealant layer are laminated.
- Patent Document 1 Japanese Patent Laid-Open No. 50-95441
- Patent Document 1 Japanese Patent Laid-Open No. 2003-72773
- Patent Document 2 Japanese Patent Laid-Open No. 11-130145
- An object of the present invention is to provide a packaging method for business-use sheet-like food that is unlikely to be contaminated with foreign matters such as paper dust at a low cost. Means for solving the problem
- the present invention is a sheet-like food, when the longitudinal polymerization surface is opened by a bag making machine. Heat-sealed (center-sealed) so that it can be opened without tearing the packaging film, and fed continuously into the packaging film that is formed into a cylindrical shape and fed in the horizontal direction.
- a packaging method for commercial sheet-like foods characterized in that each sheet is sealed by heat sealing (end sealing) so that it can be opened without tearing (claim 1).
- the packaging method for commercial sheet food according to claim 1 or 2 wherein the center seal and the Z or end seal are heat seals by a heating element having a protrusion and a heating element having a recess or groove (Claim 3). .
- the packaging method of the present invention it is possible to prevent foreign matters such as paper dust from adhering to commercial sheet food. Further, the method of the present invention can use a widely used horizontal type bag making and filling machine and can use a film with a high packaging speed and an inexpensive force, so that the cost of the product can be kept low. It is an excellent one.
- the sheet food for business use includes a sheet-like water-in-oil emulsified composition (sheet galgarin), a sheet-like oil-in-water emulsified yarn, a sheet-like flower paste, a sheet-like Chocolate may be used, but it is difficult to apply it to fluid ones.
- a sheet-like food is sealed (center seal) so that it can be opened without breaking the packaging film when the longitudinal polymerization surface is opened by a horizontal bag making and filling machine (horizontal pillow wrapping machine). Are continuously fed one by one into a packaging film that is molded into a cylindrical shape and fed horizontally. It is a packaging method for commercial sheet-like food, characterized in that each sheet is sealed (end-sealed) and sealed so that it can be opened without tearing the packaging film when opening.
- the center seal and the end seal need to be sealed so that they can be opened without breaking the packaging film at the time of opening.
- V so-called “easy peel” seal is required. If it is not easy peel, there is a possibility that a film that is torn by opening will be mixed into the product, which does not meet the object of the present invention.
- easy peel seals can be applied by publicly known methods. When using multilayer films, the seals are complete and the sealability of the packaging is improved, but the material cost is increased and will be described later. As described above, problems are caused in the lamination of the packaged articles, so that the object of the present invention is not suitable.
- the heat seal corresponds to a film in contact with the tip of the ridge by pressing two films between the heating element having a ridge and a corresponding heating element having a groove or groove. Adjust the temperature, pressurization pressure, and pressurization time of both heating elements so that only the film in contact with the recess melts and the two films fuse (adhere). stop. Then, it is possible to easily open the two films without tearing them without breaking the packaging film (easy peel). The reason is not necessarily clear, but the film portion that contacts the tip of the ridge is stretched slightly thinner by the pressure and heat from the ridge than the other portions, and the bottom of the corresponding recess is less than the tip.
- the ridge can be a pyramid with the tip cut off horizontally or rounded at its corners, but the corresponding ridges are recessed so that each of the ridges can be held together. It is also possible to provide a groove so that one row of ridges fits together. In any case The bottom of the groove or groove is preferably shaped so as to come into contact with the tip end of the protrusion when the two heating elements are held together.
- the heating element is a set of metal rolls heated by heating means such as a heating wire above the melting temperature of the film to be used (one surface is a ridge, one surface is a corresponding groove or A typical protrusion has a size of 2 mm square and a height of about 0.2 to 0.7 mm, and for example, 5 to 6 rows are provided in a roll width lcm.
- heating means such as a heating wire above the melting temperature of the film to be used
- one surface is a ridge, one surface is a corresponding groove or
- a typical protrusion has a size of 2 mm square and a height of about 0.2 to 0.7 mm, and for example, 5 to 6 rows are provided in a roll width lcm.
- two films can be sandwiched between them, and heat sealing can be performed by rolling in the vertical direction for the center seal and in the horizontal direction for the end seal, and a length equivalent to the seal length. Heat sealing can also be performed by using a pair of metal plates (projections on one side and
- the film is preferably a single layer film of HDPE or LLDPE from the viewpoint that the range of the temperature condition in heat sealing can be increased. More preferably, it is a single layer film in which HDPE and LLDPE are mixed, more preferably, a mixed film thereof. 100: 100 to 95: 5, most preferably, a single layer film of 85:15 to 95: 5 is preferable. .
- the thickness of the Finolem is 40 to 80 ⁇ m, more preferably 55 to 65 ⁇ m. Thinner than 40 ⁇ m! /, And packaging for commercial sheet-like foods, the strength of the bag itself will be insufficient and easy peel will be difficult. If the length exceeds 65 m, it is not preferable because the streaks are likely to enter the package.
- the center seal part force is made different in the length to the end of the packaging film without aligning the ends of the packaging film.
- the length up to the end of the packaging film that is folded by the inner side can be longer or shorter than that of the outer side. For example, by providing a difference of about 10mm, one side is 5mm in length and the other is 15mm in length, and the other is 15mm. .
- a film with a color different from the color of the food that is the content for example, green when normal sheet margarine is used as the content. preferable.
- the center seal and the Z or end seal can be partially performed to the extent that there is no hindrance to contamination.
- the end seal can be provided with several non-seal parts of about 10 mm, and if this is the case, the non-seal part maintains the close contact between the films, so there is little possibility of contamination.
- the non-seal part it is possible to easily release the air inside the packaging bag to the outside while preventing the entry of foreign matter.
- the end seal is provided with a non-seal part
- the packaged commercial sheet food obtained by the method of the present invention is shipped as a product, 10 to 20 sheets are stacked and put into a box.
- the air inside the bag is convenient because the side force is also lost.
- the packaged commercial sheet-like food package obtained as described above can achieve both an appropriate seal strength and an easy peel property, and can be easily opened without breaking. It is possible to prevent foreign matters such as paper dust from being mixed, and it is excellent at low cost.
- LLDPE (100%) A 60 ⁇ m thick film (colored and kneaded in green! /) Is displayed on the longitudinal polymerization surface with a horizontal pillow packaging machine (bag making machine).
- a pair of metal rolls heated to the temperature shown in Fig. 1 (center seal temperature) one surface has 2mm square in a width lcm and a height of about 0.5mm to fill the surface in 5 rows And the other one surface was provided with grooves so as to correspond to the ridges, and was heat-sealed to form a cylinder.
- the length up to the end of the packaging film folded inside by the end seal was made 1 cm longer than that of the outer side.
- Example 4 A test was conducted in the same manner as in Example 1 except that the film was HDPE (100%). At a center seal temperature of 130 ° C and an end seal temperature of 120 ° C, both moderate seal strength and easy peelability were achieved. However, in the end seal, if too much force is applied at the time of opening, tearing may occur, and the allowable temperature range of the seal is narrower than in Examples 1 to 3. Moreover, since the film was hard, wrinkles were likely to enter the bag.
- FIG. 1 is a perspective view schematically showing a sheet-like food product obtained by the present invention.
- FIG. 2 is a perspective view of the ridge.
