Description

Technical Field

[0001] The utility model belongs to the field of packaging films, and in particular relates to a packaging film and a packaging bag for soft candies, a leisure food. Background Art

[0002] At present, soft candies on the market are packaged in bags, and the packaging form is three-seal bags or zipper three-seal bags. Three-seal bags are ordinary square or rectangular four-sided flat bags. When making the bags, three sides are heat-sealed, and one side is left unheat-sealed as the entrance for filling the contents.

[0003] As the quality of life improves, consumers have higher requirements for packaging. In the past, consumers would buy bags of soft candies and eat them all or share them among multiple people. However, as living standards improve and consumption habits change, the amount of food consumed at a time is decreasing. If the original size of packaging bags are still used, there will be a large amount of leftovers. If the packaging is reduced, the packaging costs of the company will increase. This requires a solution that can satisfy small-scale consumption without significantly increasing costs. Utility Model Content

[0004] The utility model aims to overcome the defects in the prior art and provide a packaging film and a packaging bag for soft candies of leisure food.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] A packaging film for soft candies of leisure food comprises an easy-tear polyester film layer, an ink layer, a vacuum aluminum-plated polyester film middle layer and an easy-tear polyethylene layer; an adhesive layer is arranged between the ink layer and the vacuum aluminum-plated polyester film middle layer and between the vacuum aluminum-plated polyester film middle layer and the easy-tear polyethylene layer.

[0007] The thickness of the tearable polyester film layer is 10-15 μm.

[0008] The thickness of the middle layer of the vacuum aluminum-plated polyester film is 10-15 μm.

[0009] The thickness of the easy-tear polyethylene layer is 60-80 μm.

[0010] The adhesive layer is a solvent-based polyurethane adhesive layer; the thickness of the adhesive layer is 3.5-4 μm.

[0011] The ink layer is a general-purpose polyurethane ink layer for printing, and has a thickness of 2-3 μm.

[0012] The packaging film for soft candies of leisure foods comprises a center line, opening easy-tear lines arranged on both sides of the center line, and two-chamber bag easy-tear lines arranged perpendicular to the center line.

[0013] Preferably, a hanging hole is provided between the center line and the opening tear line.

[0014] The utility model also comprises a packaging bag for soft candies of leisure foods, which comprises two layers of packaging films for soft candies of leisure foods, the upper layer and the lower layer.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The packaging film for soft candies of the utility model adopts a structural form of an easy-tear polyester film layer, an ink layer, a vacuum aluminum-plated polyester film middle layer and an easy-tear polyethylene layer. Users can easily tear open the packaging film. As a preferred form, the design of the easy-tear line of the two-chamber bag can separate one bag into two independent bags for use.

[0018] Figure 2 The utility model is a schematic diagram of the apparent structure of the packaging film for the soft candy snack food. DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and the best embodiment.

[0020] It should be noted that the materials used in the packaging film of the present application are conventional materials well known to those skilled in the art, and the components are not specifically limited.

[0021] Figure 1-2 A packaging film for soft candies of snack foods is shown, comprising an easy-tear polyester film layer 1, an ink layer 2, a vacuum aluminum-plated polyester film middle layer 4 and an easy-tear polyethylene layer 6; adhesive layers are arranged between the ink layer and the vacuum aluminum-plated polyester film middle layer and between the vacuum aluminum-plated polyester film middle layer and the easy-tear polyethylene layer, which are a first adhesive layer 3 and a second adhesive layer 5 respectively.

[0022] The material of the tearable polyester film layer can be, for example, the biaxially stretched linear tearable polyester film used in CN213649017U or any other commercially available tearable polyester film, and its thickness is 10-15 μm, specifically 10 μm, 12 μm, 13 μm, 15 μm.

[0023] The thickness of the vacuum aluminum-plated polyester film middle layer is 10-15 μm, specifically 10 μm, 12 μm, 13 μm, and 15 μm.

[0024] The material of the tearable polyethylene layer can be, for example, the linear tearable polyethylene film used in CN219133497U or any other commercially available tearable polyester film, and the thickness thereof is 60-80 μm, specifically 60 μm, 65 μm, 70 μm, 75 μm, 80 μm.

[0025] The adhesive layer is a solvent-based polyurethane adhesive layer; the thickness of the adhesive layer is 3.5-4 μm, specifically 3.5 μm or 4 μm.

[0026] The ink layer is a general-purpose polyurethane ink layer for printing, and has a thickness of 2-3 μm, specifically 2 μm or 3 μm.

[0027] like Figure 2 As shown, the packaging film for the soft candy snack food comprises a center line 72, opening easy-tear lines 71 arranged on both sides of the center line, and two-chamber bag easy-tear lines 73 arranged perpendicular to the center line.

[0028] Preferably, a hanging hole 74 is provided between the center line and the opening tear line.

[0029] The utility model also includes a soft candy packaging bag for snack foods, comprising two layers of soft candy packaging films. The preparation method of the soft candy packaging bag for snack foods adopts the following steps: folding the soft candy packaging film for snack foods in half along the center line, and heat-sealing the periphery to obtain the soft candy packaging bag.

[0030] The implementation of the utility model is as follows: the easy-tear polyester film layer 1 has a thickness of 12 μm, and the ink layer 2 is printed by gravure printing, using universal polyurethane ink; the vacuum aluminum-plated polyester film middle layer has a thickness of 12 μm, and the easy-tear polyethylene layer has a thickness of 75 μm, and the ink layer, the vacuum aluminum-plated polyester film middle layer, and the vacuum aluminum-plated polyester film middle layer and the easy-tear polyethylene layer are compounded by solvent-based polyurethane glue;

[0031] In the process of preparing the packaging film for soft candies, the point breaking knife and the cutting knife are fed twice, and the heat sealing knife is fed once, so that the point breaking and cutting actions are performed every two bags to complete the production of the overall bag shape. The breaking bridge ratio of the easy-tear line of the two-chamber bag is 2:1, achieving an easy-tear effect.

[0032] From the above, it can be seen that the packaging film for soft candies of the present invention adopts a structure of an easy-tear polyester film layer, an ink layer, a vacuum aluminum-plated polyester film middle layer and an easy-tear polyethylene layer. Users can easily tear open the packaging film. As a preferred form, the design of the easy-tear line of the two-chamber bag can separate one bag into two independent bags for use.

[0033] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation method and application scope. The content of this specification should not be understood as limiting the present invention.
