Description

Technical Field

[0001] This utility model relates to the field of wet wipe packaging technology, and more specifically, it relates to a wet wipe packaging film. Background Technology

[0002] In the field of wet wipes packaging, the choice of packaging materials has a crucial impact on the shelf life, user experience, and environmental performance of wet wipe products.

[0003] For example, the wet wipe packaging film disclosed in authorization announcement number CN220947057U includes a printing layer, an aluminized layer, a heat-sealing layer and a PET structural layer arranged sequentially. The PET structural layer includes a PET film layer, a water-resistant PET film layer and a high heat-sealing PET film layer. The aluminized layer includes PET and aluminum foil plated on the PET.

[0004] In the above, the barrier properties of wet wipe packaging are improved by setting a PET structural layer, but the use of an aluminum-plated layer results in low barrier properties, leading to problems such as low transparency, difficulty in recycling, and poor high-temperature resistance. At the same time, the internal moisture of the wet wipes gradually disappears during long-term storage, resulting in poor water-locking effect and seriously affecting the consumer's user experience. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wet wipe packaging film with high transparency, easy recyclability and high temperature resistance.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A wet wipe packaging film includes a printed layer, a functional layer, and a heat-sealing layer, wherein the functional layer is disposed between the printed layer and the heat-sealing layer.

[0008] The printed layer and the functional layer are glued together on one side.

[0009] The functional layer is glued to the heat-sealing layer on the other side, and the printing layer is made of PET film.

[0010] The functional layer is made of PET silicon oxide film, and the heat-sealing layer is made of PE material.

[0011] The present invention is further configured such that the printed layer and the functional layer are fixed together by solvent-free adhesive.

[0012] The present invention is further configured such that the functional layer and the heat-sealing layer are fixed together by a flexible water-based adhesive.

[0013] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0014] The functional layer uses PET silica film, which has excellent oxygen and water vapor barrier properties, thereby improving the water-locking effect. At the same time, PET silica film has high transparency, easy recyclability and high temperature resistance, achieving high barrier properties. The combination of the printing layer, functional layer and heat-sealing layer ensures the integrity and airtightness of the packaging, further improving the barrier properties. Solvent-free adhesive or flexible water-based adhesive is used for bonding to ensure a tight bond between the printing layer, functional layer and heat-sealing layer, reducing the volatilization of excess solvents and improving environmental performance. Attached Figure Description

[0016] Printed layer 1, functional layer 2, heat-sealing layer 3. Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figure 1 As shown, the wet wipe packaging film includes a printed layer 1, a functional layer 2, and a heat-sealing layer 3. The printed layer 1 and the functional layer 2 are bonded together with solvent-free adhesive or flexible water-based adhesive, and the functional layer 2 and the heat-sealing layer 3 are also bonded together with solvent-free adhesive or flexible water-based adhesive. This ensures a tight bond between the printed layer 1, the functional layer 2, and the heat-sealing layer 3, reduces the evaporation of excess solvents, and improves environmental performance.

[0020] The printing layer 1 uses film materials such as PET or PA to print product information and patterns. It is cleaned and pre-treated to ensure printing effect and improve the aesthetics of the packaging.

[0021] Functional layer 2 is made of PET silica film. PET silica film has excellent oxygen and water vapor barrier properties, which effectively maintains the moisture and hygiene of the wipes, resulting in high barrier properties. The high barrier properties of PET silica film can effectively prevent the wipes from losing water during long-term storage, thereby improving the water-locking effect.

[0022] First, PET silica film has high transparency, making it easy for consumers to observe the condition of the wipes. Second, PET silica film is biodegradable and easily recyclable, meeting environmental protection requirements and reducing environmental pollution. Third, it has high temperature resistance, maintaining stable performance under harsh environmental conditions and extending the product's shelf life. These characteristics make PET silica film highly transparent, easily recyclable, and heat-resistant.

[0023] The heat-sealing layer 3 is made of PE or PP material and is used for sealing the packaging film to ensure the integrity and airtightness of the packaging. The thickness and specifications are determined according to the packaging requirements.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
