[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.
[0024] like Figure 1 - Figure 4 As shown, this embodiment provides a multilayer structure of a high-barrier composite packaging film, including an outer film layer 101, an inner film layer 102, an outer film layer 103, and an inner film layer 104 for wrapping.
[0025] A filling interlayer 1 is wrapped between the outer membrane layer 101, the inner membrane layer 102, the outer membrane layer 2 103, and the inner membrane layer 2 104;
[0026] The two sides of the filling interlayer 1 are respectively distributed with filling bladders 105, which are circular, square, rhomboid, elliptical, polygonal or a combination of the above shapes.
[0027] The main body 2 of the packaging film consists of a filling interlayer 1, an outer film layer 101, an inner film layer 102, an outer film layer 2 103, an inner film layer 2 104, and a filling bladder 105. Filling bladders 105 are distributed on both sides of the outer surface of the filling interlayer 1. The outer sides of the filling bladders 105 are covered by the inner film layer 102 and the inner film layer 2 104, respectively. The outer sides of the inner film layer 102 and the inner film layer 2 104 are covered by the outer film layer 101 and the outer film layer 2 103. The main body 2 of the packaging film wraps the material. After wrapping, if a sharp object punctures the outer film layer 101, inner film layer 102, or outer film layer 2 103 on either side or one side of the main body 2, it will be vulnerable to damage. 3. When the inner membrane layer 104 and the filling bladder 105 are connected, the material inside the filling bladder 105 flows out. Upon encountering oxygen, the material reacts with it, solidifying the colloid inside the filling bladder 105. This colloid is an anaerobic adhesive, which is liquid and flowable in the absence of oxygen. When the packaging film uses anaerobic adhesive material and is exposed to air, the presence of oxygen inhibits its polymerization reaction. However, when the packaging film wraps an item, a relatively oxygen-free environment is created inside, causing the anaerobic adhesive to rapidly polymerize and solidify. This achieves tight adhesion and fixation of the item, sealing cracks and providing a barrier function.
[0028] The filling sac 105 is a hollow cavity structure, and the filling sac 105 is attached to the inner membrane layer 102 and the inner membrane layer 104.
[0029] The outer membrane layer 101, the inner membrane layer 102, the outer membrane layer 2 103, and the inner membrane layer 2 104 are fixed and covered by a colloid.
[0030] The filling bladder 105 on the filling interlayer 1 is a single-sided or double-sided covering structure.
[0031] The cavity between the filling interlayer 1 and the filling capsule 105 is a sealed structure.
[0032] The cavity between the filling interlayer 1 and the filling capsule 105 is an oxygen barrier structure.
[0033] As shown in Figure 1 - Figure 4 The working process of the multi-layer structure of the high-barrier composite packaging film provided by the embodiment is as follows:
[0034] Step 1: The packaging film body 2 is composed of the filling interlayer 1, the outer film layer one 101, the inner film layer one 102, the outer film layer two 103, the inner film layer two 104 and the filling capsule 105. The filling interlayer 1 is distributed with the filling capsule 105 on the outside of both sides. The outside of the filling capsule 105 is covered with the inner film layer one 102 and the inner film layer two 104. The outside of the inner film layer one 102 and the inner film layer two 104 is covered with the outer film layer one 101 and the outer film layer two 103.
[0035] Step 2: The packaging film body 2 is wrapped with materials. After wrapping, when the outer film layer one 101, the inner film layer one 102, the outer film layer two 103, the inner film layer two 104 and the filling capsule 105 on both sides or one side of the packaging film body 2 are pierced by sharp objects, the materials in the filling capsule 105 flow out.
[0036] Step 3: The materials in the filling capsule 105 flow out and react with oxygen to solidify the colloid in the filling capsule 105 into a solid, which not only seals the cracks but also realizes the barrier function.
