443977 A7 B7 經濟部智慧財產局員工消費合作社印製 五、發明説明（I ) [發明背景] 本發明係關於用於包裝的材料，其適用於一欲進行包 裝的物件，而且這種包裝材料包含一個可以個別地切割成 個別的薄片並經由環繞折疊而使欲包紮之物件封閉的膜片 〇 非爲限定性的，本發明特別相關於甜點及巧克力產品 ，或其他如原料塊之消耗品的包裝領域。 一般而言，物件是個別地包裝在一張適當尺寸和形狀 之預先印刷的長方形膜片中，然後該個別包裝之物件則更 可藉由一適當尺寸的包裝袋子而大批量地裝塡。例如一種 呈平行六面體形狀而欲進行包裝的物件可依據一般通用的 包裝方法而放置在該相反側的中央，亦即在一個長方形膜 片之未印刷的側邊。然後，該兩個縱向側邊則靠倚著該物 件之縱向的表面而垂直地向上翻轉(或向下，此依據物件的 方位以及包裝機器的型式而定）。隨後，該橫向側邊便靠倚 著該物件之兩個橫向的表面而垂直向上翻轉，且它們的上 側端緣也平坦地折疊在該物件的頂部表面上；上述之最後 兩個操作步驟必須連續地進行，且該具有縱向側邊之傾斜 折疊的步驟亦必需已完成向上翻轉。最後，當該縱向側邊 的頂部端緣（其在此同時已經變成不規則四邊形的垂片）交 互地叠置在該物件的頂部表面，則包裝的動作才算完成。 然而必需注意的是，包裝的操作係必須依據該欲包裝 之物件的形狀以及進行包裝之機器的特性而定，因而其它 運用包裝膜片進行包裝的程序是有可能的，且這些包裝的 3 I---------^------,訂 ----：----漆 (請先閲讀背面之注意事項再i*.本頁) 本紙張尺度適用中图國家標準（CNS ) A4規格（210X297公釐） 443977 A7 B7 經濟部智慧財產局員工消費合作社印製 玉、發明説明（y) 程序是依循著一組嚴謹規劃之折疊線條的樣式而進行著。 這個包裝膜片之折疊線條的樣式對於使用相同包裝方法之 欲進行包裝的物件而言總是保持著相同。 在此，其所呈現之一個重大問題是在該包裝操作結束 之際，其必需固定該褶層以便保持該包裝情形的閉合。這 個固定作用只要在選擇使用一種可做爲基底之特別的薄膜 始可達成；且此薄膜的基底必需具備諸如柔軟性以及特別 是一種在該膜片已於包裝期間完成折疊之後可有著不會回 復至其原始位置的極佳傾向等適當的機械性質。 特別地，當包裝諸如甜餅、胡核桃糖果、棒棒糖、大 麥芽糖、覆蓋巧克力的糖果棒等之甜點，或原料塊時，前 述的問題便會呈現。 一個已知的解決方法是選擇具有高度柔軟性的特殊基 底材質，例如：蠟紙、玻璃紙、鋁箔紙或者是一種包含一 適當劑量並可以增進此基底材質之柔軟性的合成薄膜。 但是，這個方法卻會大大地限制選用該薄膜做爲包裝 之基材的可行性，或者極大地增加它的成本。 用做包裝諸如原料塊之特定物件的膜片亦是爲人所熟 悉者；而包裝材料在這種薄膜中是藉由綁捆而封合。爲此 目的，該膜片在其右側邊，亦即在該欲進行包裝之物件外 部的那一側邊，包含一個熱密封塗層的結構，且此結構係 適合該在包裝期間所製成的褶層結構。 這個包裝方法所具有的缺點是該包裝機器必需針對此 方法而特別設置一個熱源。此外，如果這個熱源具備發熱 4 I.

Description of the Invention (I) [Background of the Invention] The present invention relates to materials used for packaging, which is suitable for an object to be packaged, and this packaging material contains A membrane that can be individually cut into individual sheets and closed by wrapping around the object to be bandaged. It is not limiting. The invention is particularly relevant to the packaging of desserts and chocolate products, or other consumables such as raw materials. field. Generally speaking, the articles are individually packaged in a pre-printed rectangular film of appropriate size and shape, and then the individually packaged articles can be packed in large quantities by a suitably sized packaging bag. For example, an object in the shape of a parallelepiped to be packaged can be placed in the center of the opposite side, that is, on the unprinted side of a rectangular membrane, according to a generally used packaging method. The two longitudinal sides are then flipped vertically up against the longitudinal surface of the item (or downward, depending on the orientation of the item and the type of packaging machine). Subsequently, the lateral sides are turned upside down by leaning against the two lateral surfaces of the object, and their upper end edges are flatly folded on the top surface of the object; the last two operation steps above must be continuous And the step of tilting and folding with longitudinal sides must also be completed. Finally, when the top edge of the longitudinal side (which has also become an irregular quadrangular tab at the same time) overlaps the top surface of the article alternately, the packaging action is completed. However, it must be noted that the operation of packaging must be based on the shape of the object to be packaged and the characteristics of the packaging machine. Therefore, other packaging procedures using packaging films are possible, and the 3 I --------- ^ ------, Order ----: ---- Paint (Please read the precautions on the back before i *. This page) This paper is applicable to the countries in the figure Standard (CNS) A4 specification (210X297 mm) 443977 A7 B7 The jade and invention description (y) printed by the employee consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs follows a set of carefully planned folding lines. The pattern of the folded lines of this packaging film is always the same for items to be packaged using the same packaging method. Here, it presents a major problem that at the end of the packaging operation, it is necessary to secure the pleats in order to keep the packaging situation closed. This fixing effect can only be achieved if a special film that can be used as a substrate is selected; and the substrate of the film must have such properties as softness and especially a non-recovery after the film has been folded during packaging. Appropriate mechanical properties such as excellent tendency to its original position. In particular, the aforementioned problems arise when packaging desserts such as cookies, pecan confectionery, lollipops, maltose, chocolate-covered candy bars, etc., or raw pieces. A known solution is to choose a special substrate material with a high degree of flexibility, such as stencil, cellophane, aluminum foil, or a synthetic film that contains an appropriate amount and can increase the flexibility of the substrate material. However, this method will greatly limit the feasibility of using the film as a packaging substrate, or greatly increase its cost. Membrane sheets used to package specific objects such as raw material blocks are also well known; packaging materials in such films are sealed by bundling. For this purpose, the membrane contains a structure with a heat-sealable coating on its right side, that is, on the outside of the article to be packaged, and this structure is suitable for those made during packaging. Pleated structure. The disadvantage of this packaging method is that the packaging machine must be provided with a heat source specifically for this method. In addition, if this heat source has a heat-generating 4 I.

Inventive (today) board, the bundling action can only be achieved on the flattest surface of the object to be packaged, and in addition to the time required for welding In addition, it requires a relatively high pressure that most products cannot withstand. Another disadvantage is that this packaging method is completely unsuitable for packaging heat-sensitive items, especially chocolate products, and it is not suitable. In order to select a packaging substrate with low heat resistance, the patent application No. EP-0,870,695 proposes a packaging film to be folded by surrounding the object, and the right side of the object, that is, the side that will become the outer surface of the object Structure with a cold seal coating * and the configuration of this structure will change the area of the sealant coating when the membrane is folded around the object Overlapping. Therefore, if the specific properties of the diaphragm material for fixing the pleats are poor, the area of the sealant coating can be used to fix the pleats. However, this diaphragm has a feature that can cause the diaphragm to close and At the same time, the thermal bonding lacquer has the disadvantages described above. And another disadvantage of the diaphragm is that the opposite side must have a non-adhesive slender strip so that the film can be fed out from a roller. [发明 槪 要] Therefore, the object of the present invention is to provide a new packaging material that allows the selected film to become quite wide and can be stored on a roller. To achieve this, the present invention proposes a design for packaging an object Packaging materials, especially food products, this packaging material contains a film stored in a roller manner, and the film can be cut horizontally into individual films, and the object is closed by being folded around, which is characterized by The 5 paper scale towel making thread!

Description of the invention (f) The film contains a strip of cold-sealed coating at least along the lateral end edge of each diaphragm, which is elongated The strip allows the film to be affixed to it under control and is strong enough to cause the covering material to close, but not too strong to tear the film output by the roller. Preferably, the film is Each transverse end edge of each diaphragm includes a strip of cold-seal coating, one of which is on the right side of the diaphragm, and the other is on the opposite side of the diaphragm. The inventor's company has been surprised to find that once the dressing membrane is closed by folding, a thin film coating of at least partly known art and a well-defined cold seal coating can be used as a packaging material The result is a pleated layer that can be tightly fixed and the film can also be stored on a roller. This fact is that the substance that should be used as a sealing coating has little or no ability to adhere to a smooth surface or be treated as a surface for this purpose; instead, it exhibits good performance when it is applied to each other during folding. Paste effect. Therefore, the pleated layer can be fixed simply by lightly applying pressure and overlapping each other by a specific area of the sealant coating, and this situation can be achieved without having to fold the packaging material other than Accessories. According to the present invention, the cold-sealed language is intended to make people realize that the sealing effect is achieved instantaneously by simply contacting a temperature between about 0 and 50 ° C. In this fact, temperature is not a key parameter to obtain a seal by cold-sealing the coating, and has no practical impact on the quality of the seal achieved. Therefore, no additional heat is required to achieve sealing at the ambient temperature at the location where the packaging unit is located. In fact, all the above-mentioned cold-sealed 6 sheets have been used in a base material layer.

Description of Invention (C) The coating has received little or no coating No deformation was encountered. In the case of using a cold seal coating on a non-flat base material, it is likely to cause a major problem that is hindered by the adhesive nature of the cold seal coating itself. Therefore, the present invention allows the use of Cheap and better film (hardness, printability, aesthetic appearance) for packaging objects, and there are no restrictions on the shape of the objects. As for the use of rigid films, it has hitherto required packaging by folding. Hard films must be avoided. This is because these hard films have a very low ability to fold the pleats. When a roller for applying a sealing coating on one side of the film is to be packaged, it can be placed on the film. Another Apply a non-adhesive coating on it, so that it can prevent the contact between the surface coated with the sealing coating and the other surface while rolling. However, it must be noted that: When a specific base material is used in conjunction, there will be a so-called " dry " cold seal coating, and this coating does not require this non-stick coating. These two methods can also be used in the context of the present invention According to an advantageous embodiment of the present invention, the structure of the sealant coating region includes two elongated w-shaped structures arranged along two opposite side edges of the diaphragm, one in the An elongated strip between two w-shaped structures and along the third side of one of the diaphragms and two areas on the two corners of the fourth side of the diaphragm * This configuration is in a folded structure The slender strip of the sealing coating can have a width of the order of 4 mm.

The description of the invention (t) and the order of its pleats have different forms. In addition to the pleats that are to be produced In addition to the sliver structure, each film has a sealing coating sliver along one end edge of its third side. This sliver will be on the tab, and the tabs generated at the end of the packaging process will be It will be the first to be bent down to the base of the object to be packaged, and connected to the last downwardly bent tab. The membrane of each packaging film may also contain an additional sealing coating. Area 'This sealing coating allows the last downwardly bent tab to adhere to the base of the packaging item and thus act as a portion that ensures the packaging material is closed. According to another embodiment of the present invention, it is possible to provide a so-called " soft " type cold-seal coating elongated strip along the end edge of one of the tabs which are finally bent downward at the end of the packaging operation. Unlike the dry coating mentioned earlier, this type of coating will stick to the smooth surface on the opposite side of the packaging film. This elongated strip of soft sealing coating provides good adhesion between the two longitudinal tabs that are bent down at the end of the packaging operation, and thus allows for a sealable and closed packaging 'and by reducing Effects such as moisture, odor, dust, or the like on the article improve the storage period of the packaged article. However, this adhesive effect between the soft coating and the smooth surface on the opposite side of the film must never be inverted, because when the film is encapsulated and stored on a roller, it must still be able to be pulled out. Without incurring tears. In other words, it must be selected for the soft sealing coating to suit the characteristics of the base material to which it is applied, so that on the one hand it can be weakly attached to the opposite side of the base material to allow packaging of the film Available from a roller 8 n.

The invention description (7) is loose and pulled out; and, on the other hand, it is hard enough to provide the package to close almost tightly. Here I proposed a controlled adhesion effect. This controlled adhesion effect also has the advantage of opening and re-tightening the package countably, but without significantly reducing its adhesion quality. As mentioned earlier, the present invention One benefit is that it can have a wide range of applications in terms of the properties of the base material used. Examples of suitable base materials are about 10 to 100 microns thick and are extruded and oriented polypropylene, cast thin Plastic films such as polypropylene, polymer, polyethylene, extruded and oriented polyamide, or cast thin polyamide, etc. According to the invention, it is also possible to use a paper-based base material (smooth finish) Or coating). In general, according to the present invention, any lining material or flexible packaging material is suitable as the base material. These different substrates can be a single layer, a single layer treated with metal or a plurality of Made of thin sheet and / or co-extruded layers. The choice of cold seal coating is not a critical factor. As for soft cold seal coatings, it faces the problem of pressure sensitive adhesive because This permanent sticky adhesive substance will be instantly attached to most of the material surface under the effect of slight pressure. A general principle is that for pressure-sensitive adhesive substances, modified glass is mixed. Materials, phenol-formaldehyde resins, hydrocarbon resins (wax agents), etc. are basic natural and / or artificial rubber composites. In addition to rubber, it can also be widely used alone or in combination. Polymer based on styrene, methacrylic acid or vinyl ether, or a material mixed with resin.

Description of Invention (/ D) Right side or printed side of sheet 20 (Please read the precautions on the back first and then the date page) The cold-seal coating is configured on a structure suitable for the folding line structure made during packaging, and it will be described later with an example ; In the case of FIG. 1, it has two slender strips 24 and 26 structures that are generally W-shaped and have widths on the order of ± 4 mm along the opposite sides of the diaphragm 20 bis, and one Along the slender strip 28 along the third side of the diaphragm between the two sides in a W-shaped pattern. On the opposite side of the side of the slender strip 28, there are also two cold areas in its corners. Seal-coated areas 30 and 32. Compared to the original film stored on the roller, the slender strips 24 and 26 are in the longitudinal direction and the slender strip 28 is in the lateral direction. On the roller, these are different The right side of the adhesive coating of the slender strip is on the outside of the zigzag portion of the roller. The film 20 printed by the consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs and printed on Figure 1 can be made in a directional manner. 25 micron thick polypropylene film with or without hardening A thin printed or lacquered layer (eg, a product numbered 10-612205-4 MX41 manufactured by SIEGWERCK, Inc.) that can increase the adhesion of the printing ink.

Description of the invention (丨 h is a sticking only to itself In other words, 'the coating does not stick to the untreated smooth opposite side of the film' and allows the film to be easily packaged and stored using a roller 'without Cause any problems that cannot be rolled. And 'this coating has a low coefficient of friction (COF) quality of the order of 0.2 to 0.6 for metal surfaces' and the coefficient of friction on metals is usually in the order of 1 to 1.5 Such a low coefficient of friction can reduce the disadvantages of film blocking and sticking to the folded box. An operation method using a film 20 as shown in Fig. 1 and used to package a cake having a substantially parallelepiped shape 'Will be described with reference to Figures 2 to 8. The film is wrapped over the pastry with its opposite or untreated side facing the pastry' so that the sliver 28 and the tool The opposite sides of the gluing areas 30 and 32 can be along the longitudinal direction of the pastry and the W-shaped configuration is along the transverse direction of the pastry. Then, as depicted in FIG. 2, the film 20 The sides are then bent down onto the longitudinal surface of the pastry. Subsequent operations include folding the central area of each side of the diaphragm so that the structures 24 and 26 reach down to the side of the pastry 34 On the surface of the side, as depicted in Figure 3. This operation is achieved by folding the longitudinal side of the diaphragm 20 along the inclined folding lines 36 and 38. As shown in Figure 3, The two seal-coating w-shaped structures 24 and 26 (the item with the reference number 26 is not shown in Figure 3) are arranged so that the two outer branches of the W-shaped structure are along the fold line 36 and 38 are extended 'and the inner part of the V-shape is placed against the lateral side of the cake 34 13 03 (Please read the precautions on the back first and then β this page), -B Dimensions of this paper逋 Printed in China National Standard (CNS) A4 (210X297).

Description of the invention (/ standing) 〇 The next operation step is to align the two moving edges defined by the folding lines 36 and 38 on each side of the cake 34 as shown in Figure 3. The directions indicated by arrows 1 and 2 are folded down into the interior. This operation is used to make the outer strip of the W-shaped seal coating structure (that is, the strip extending along the folding lines 36 and 38) ) Is arranged above the inside of the V-shaped slender strip and achieves the result according to the structure of Fig. 4. Obviously, the order of these folds is the same on both sides of the cake. If the two W-shaped All the slender strips of the type structure 24 and 26 are completely reset, and preferably, all the cold sealing coatings used by them can be self-adhesive, then the structure of FIG. 4 is a stable structure. The ground system can attach the generated pleats to it. The next folding procedure will be as depicted in Figure 5, which involves folding the lower part of the previous fold and the side flaps of the wings down onto the bottom side of the pastry 34. This operation is accomplished by folding the longitudinal side edges into oblique folding lines 40, 42, 44 and 46 which can be converted into irregular quadrangular tabs 48 and 50 to fold the longitudinal side edges. The result of this folding step can be clearly seen in Figure 6 which is depicted from the bottom and hidden inside the surface shown in the previous figure. Similarly, it must be noted here that the two cold-seal coating regions 30 and 32 are lined along the fold line 40 of the tab 48 with their inside inclined edges (also shown in Figure 1). And 42 'is set in a stretched manner as shown in Figure 6. Figures 7 and 8 depict the final stages of the packaging process. First of all, the 14!

Description of the invention ([)) The tabs 50 with the seal coating slender strip 28 are folded down above the inner side as shown in Figure 7. Then, the second tab 48 is folded down above the tab 50 to form a structure as shown in FIG. When the tabs 48 are bent downward, the two seal-coating regions .30 and 32 are partially superimposed on each other and locally applied to the adhesive elongated strip 28 of the tab 50. As a result, assuming that the tab 48 is not only glued to itself and adhered to the tab 50, all the pleats are firmly held in position to achieve a stable structure as shown in FIG. It must be noted, however, that when the tab 48 is folded down onto the tab 50, the glued slender strip 28 will stick to the glued areas 30 and 32 with only its ends. In contrast, the central portion of the sliver will contact but not adhere to the opposite side of the tab 48. In other words, when the diaphragm in Figure 1 forms a solid and permanently closed package, it is not a closed seal. The packaging procedure described below is done automatically on a packaging machine. In this article, it is important that the packaging film used is suitable for use on an existing packaging machine without any modification or adjustment. However, it must be noted that the packaging material described below is only one example of a folded configuration on a known machine. Other machines may perform folding operations along different folding line patterns. Based on this situation, the form of the adhesive structure as shown in Fig. 1 must be suitable for the pattern of folding lines produced by the construction machine. Now, a second embodiment of a packaging film according to the present invention and generally designated by reference numeral 52 will be described with reference to FIG. 15 I 11 n I ^ J— ^ 1 ϋ (Please read the precautions on the back before reading this page) This paper size is applicable to China National Standard (CNS) A4 size (210X 297 mm) 443977 Employees of Intellectual Property Bureau of the Ministry of Economic Affairs Cooperative prints A7 B7 V. Description of the invention (丨 10) A film made of, for example, a directional polypropylene, which is the Division *, is ready to be printed; and the polypropylene has the same situation as in Figure 1 And deposited cold seal coating structure. Then, an elongated strip 54 of a soft cold seal coating is deposited only along the adhesive elongated strip 28. 22-392 or 22-263 products made by Croda Corporation deposited at a dose of 3 g / m2 can be used for this purpose. The adhesive of the elongated strip 28 is used as a paint layer for the soft adhesive of the elongated strip 54. The soft adhesive nature of the elongated strip 54 can be attached not only to itself but also to an untreated smooth surface on the opposite side of the membrane 52. The result is when the membrane 52 is packaged at the end of the packaging process in accordance with Figures 2 to 8 and when the tab 48 is bent down over the tab 50 (as shown in Figures 7 and 8) and When the adhesive elongated strip 54 is reached, the opposite side of the tab will be attached to the adhesive elongated strip 54 of the tab 50. Therefore, the packaging material produced in this way not only has the good performance that allows the pleated layer to be fixed in position, but also achieves a substantially sealing effect. According to another feature of the present invention, the soft sealing coating is selected to have controllable adhesive properties, or rather, to make the adhesive properties strong enough to seal the packaging material, and It will not be too sticky to restore its adhesive properties. In other words, the slender strips 54 of the adhesive must be able to be removed from the smooth surface of the membrane without causing difficulties. This situation allows the film to be stored on a roller without the risk of tearing during the loose feed output. Fig. 10 shows a third embodiment of a packaging material having advantages according to the present invention, which is generally designated by reference numeral 56. _ ____ 16 This paper size is ϋCasu Su quasi (CNS) A view (2 丨 to 297) ———— install—r *: Order I ~ n I line (please read the precautions on the back before J * 本 I ) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 443977 A7 ___B7__ 5. Description of the Invention (丨 f) Again, it can be made of directional polypropylene, and it is best to finish after depositing a paint layer. Properly printed film. A non-stick coating 60 is then deposited on the entire right side. Suitable non-adhesive products may be a mixture of a polyamide resin and a polyethylene wax applied at a dose of 1,5 g / m2 (e.g., 10-609345-3P product manufactured by SIEGWERCK Corporation and by 994404-X product manufactured by SICPA company). A form 22 of the cold seal coating exactly as shown in Figure 1 can be applied to this coating. Then, it is more or less possible to apply a dry cold-seal coating slender strip to the back side portion between the areas 30 and 32 on the right side at the dotted line as indicated by reference numeral 58. As shown in Figures 2 to 8, when the film 56 is used for packaging, the adhesive strip 58 will be located inside the tab 48 at the end of its packaging operation (as shown in Figure 7); and After the tab 48 is folded and covered, it will be attached to the adhesive strip of the tab 50 to form a substantially closed packaging result. When the film according to FIG. 10 is stored in the form of a roller, generally, the back side of the adhesive strip 58 will contact the right side of the non-adhesive coating 60, but neither of them will Attach. Nonetheless, the elongated strip 58 will contact the glued elongated strip 28 as the roller advances and after a certain amount of rotation. At this time, by selecting the adhesive properties of the elongated strip 58 and its controllable degree of adhesion, it may fade from a roller? And loose film. As shown in Fig. 9, it must be noted that a non-adhesive coating similar to one of Fig. 10 can also be provided on the right side of the membrane 52 so as to be more easily faded?

Films made in this way can be loosened or rolled back up to ten times from a roller without losing the adhesive properties necessary to form a sealed package. Figure 12 shows an implementation like Figure 10 Example of another simplified style. The diaphragm 62 in this variation simply includes an elongated strip 58 on its backside along its one end edge (before cutting, relative to the transverse end edge of the film on the roller) of FIG. 10 A comparable cold seal coated elongated strip 64, and another cold sealant elongated strip 66 on its right side along the opposite end edge and comparable to the elongated strip 28 of FIG. The production of such a film can be carried out as described previously herein with reference to FIG. The two strips 64 and 65, which are drawn by way of illustration and mentioned earlier, can be made into an egg shape so that they can be easily loosened from a roller. In other words, in this modified form as shown in FIG. 10, the structures of the sealing coatings 24, 26, 30, and 32 in FIG. 10 are not used with β. Therefore, when FIG. 9 and 10 are not needed, This embodiment can be applied when the hermetic sealing is allowed in the embodiment and the sealing along the folding line is not achieved.
