Description

Flexible overlapping laminated laminate, laminate and method for making tube from laminate

The present disclosure is generally directed to flexible packages, and more particularly to a flexible laminate tube for use in packaging products.

Different types of flexible tubes are conventionally used to package several types of products, such as liquid products, semi-solid products, and the like, such that these products can be delivered to consumers. All of these flexible tubes may also include printed information such as details of the packaged product, brand name, logo, trademark, date of manufacture, expiration date, batch number and/or any other general information for convenient consumption. Identify the products you need on the market. Depending on the type of flexible tube, these flexible tubes can include printed information on the exterior surface or on the inner layer. For example, if a flexible tube is made by an extrusion process, the information will have to be printed on the inner surface of the flexible tube. This type of printing is accomplished by surface printing or pasting a pre-printed sticker after the flexible tube or flexible tube has been fabricated. Printed information on such flexible tubes is generally not stable to preserve and can be easily peeled, smeared, soiled or obscured during handling, transportation, use, touch and the like.

Due to this problem, a flexible tube including printed information on its inner layer is used. In particular, a flexible tube comprising printed information on its inner layer is typically made of a multilayer polymeric laminate. In general, printed information is reverse printed onto a transparent polymeric film and adhered to other polymeric films to produce a laminate. Such laminates can be used to make flexible laminated tubes by overlapping the opposite edges of the laminate and sealing the opposite edges by heat sealing.

However, the heat sealing method is generally limited to only such laminates, wherein the inner layer and the outer layer are heat sealable with each other. Other sealing methods, such as hot melt extrusion sealing in several application examples, will cause the laminate to melt and cause the laminate to separate. Moreover, in any overlapping sealing action, one edge of the laminate is typically exposed to the product packaged within the tube. When the product remains in fixed contact with the exposed edges of the laminate, the particular product will result in a laminate separation of the different layers of the laminate. This layered separation can also smudge or blur the printed information. In addition, such flexible tubes may also include different issues regarding safety, forgery, tamper proof, aesthetics, and the like. Because of the frequent occurrence of counterfeit products on the market, such flexible tubes are not trustworthy.

Thus, a need exists for a suitable sealing technique for the overlap of laminate edge seals to create a sturdy and durable flexible laminate tube from a wide variety of laminates. In addition, the need to avoid problems with security, forgery, tamper proof, aesthetics, and similar items exists to prevent counterfeit products from appearing on the market. In addition, there is a need to prevent the printed information of the laminated tube from being separated, soiled, or blurred.

As shown in Fig. 1, when the hollow body member (102) is obtained, a sealing region (hereinafter referred to as "" is defined as a sealing strip (300) that is disposed between the opposite overlapping edges (200a) and (200b). The sealing strip (120)") is covered by the use of at least one protective strip. At least one protective strip is configured to be longitudinally along the overlapping edges (200a) and (200b) of the laminate, on at least one of the inner layer (204) and the outer layer (202), from the hollow body member (102) At least one of the inner side and the outer side of the inner side and the outer side are used to cover the overlapping edges (200a) and (200b), as shown in Fig. 3, the two protective strips (800) and (810) are illustrated. The protective strips (800) and (810) are respectively sealed along the longitudinal direction to the inner side surface (204a) and the outer side surface (202a) of the laminate (200) for manufacturing the tube (100). The protective strips (800) and (810) are laminated along the tube (100) along a sealing strip (120) extending longitudinally from the inner and outer sides of the tube (100) (refer to Figure 1). The edges of the sheet are covered to prevent lamination separation and provide additional seal strength. The protective strips (800) and (810) may be a single layer film for sealing to a different inner layer of the laminate (200) (204) And outer layer (202). However, without departing from the scope of the present disclosure, the protective strips (800) and (810) may be multilayer films or laminates that are unprinted and not metallized for sealing to the laminate ( 200) Individually different inner layers (204) and outer layers (202).

In addition, protective strips (800) and (810) may be added to the laminate (200) before the tube (100) is formed and sealed or during its manufacture and sealing. In addition, the protective strips (810) provided on the outer sides of the edges (200a) and (200b) can be trimmed (as shown in Figure 3) for a smooth transition surface to improve in the tube (100) The tactile sensation on the outside side.

Referring now to Figure 8, a method (900) for making a tube (100) is illustrated. The reference to the above disclosed figures will be used herein to describe the method (900). The method (900) is performed from step (910). Further in step (920), a laminate, such as laminate (200), (400), (500), (600) or (700), is folded to extend the longitudinal extension of the laminate to the opposite edge. They are overlapped to form a hollow body member (102). The laminates used herein include all of the features and limitations of all of the above disclosed laminates. In addition, the folding action of the laminate is carried out in the same manner as described above to overlap the longitudinal extension of the laminate relative to the edges and is not included herein for the sake of simplicity. Further, in step (930), the weather strip is introduced into the middle of the two longitudinally extending opposite overlapping edges of the laminate. The sealing strip is the same as the sealing strip (300) and the sealing strip is provided for lamination in the same manner as described above. The two longitudinal extensions of the sheet are in the middle of the overlapping edges. For the sake of simplicity, the above explanations are not included herein. Further, in step (940), as described above, the weather strip is sealed to the middle of the two longitudinally extending opposite overlapping edges of the laminate. As described above, the protective strip is also sealed to cover the sealing strip after the sealing action of the sealing strip is completed or during the sealing action of the sealing strip to prevent the edge of the laminate from being inside the tube. The laminate separation is created and/or used to provide strength to the joint and the smooth transition surface to improve the feel on the outer side of the tube. The hollow member is cut to the desired length on the line of the forming and sealing machine to produce the tube (100). The method (900) ends at step (950).

The tube (100) of the present disclosure provides the following advantages. Tubes made from different types of laminates are strong and durable. The tube can be effectively sealed and prevented from laminating separation and printed information from being soiled or obscured. In particular, the protective strip precludes the edges of the laminate from being exposed to the product packaged within the tube, thus precluding the different layers of the laminate to create a laminate separation and preventing the occurrence of lamination separation and printing information being manipulated Dirty or blurred. The tube has strength to the joint and provides a smooth transition surface to improve the feel on the outer side of the tube. The use of a sealing strip to provide a sealing effect seals all types of laminates. Such a sealing strip also precludes the laminate from being melted at the same time as the seal, thereby reinforcing the sealing technique for manufacturing the tube. Pipes can pre-empt different restrictions on safety, forgery, tamper proof, aesthetics and similar items, generally to prevent counterfeit products from appearing on the market.
