Description

Technical Field

[0001] This utility model relates to the field of tropical blister aluminum technology, specifically a tropical blister aluminum with high barrier properties. Background Technology

[0002] Tropical blister aluminum materials are widely used in various packaging industries such as pharmaceuticals, food, and cosmetics due to their lightweight, high plasticity, and good appearance. However, although these traditional blister aluminum materials perform well in normal environments, their limitations in barrier properties become apparent when faced with high-temperature and high-humidity climatic conditions.

[0003] Under extreme climatic conditions, traditional blister packs often fail to effectively prevent the penetration of harmful substances such as oxygen and water vapor due to the combined effects of temperature and humidity. This permeated oxygen and water vapor not only shortens the shelf life of the packaged items but also easily triggers chemical reactions, leading to spoilage, damage, and even the production of substances harmful to human health. Therefore, for items requiring long-term storage or transportation in tropical regions, traditional blister packs are clearly inadequate in meeting their barrier performance requirements. Utility Model Content

[0004] A tropical-type blister aluminum with high barrier properties includes a thin aluminum sheet layer, a heat-sealing coating fixedly disposed on the upper surface of the thin aluminum sheet layer, an adhesive-reinforcing coating fixedly disposed on the upper surface of the heat-sealing coating, an anti-corrosion coating fixedly disposed on the upper surface of the adhesive-reinforcing coating, a high-barrier polymer coating fixedly disposed on the lower surface of the thin aluminum sheet layer, a nanocomposite coating fixedly disposed on the lower surface of the high-barrier polymer coating, and an inorganic barrier coating fixedly disposed on the lower surface of the nanocomposite coating.

[0005] Preferably, the heat-sealing coating is made of polypropylene material to ensure good heat-sealing performance and sealing strength.

[0006] Preferably, the reinforcing adhesive coating is made of polyurethane material to improve the adhesion between coatings and the stability of the overall structure.

[0007] Preferably, the nanocomposite coating comprises nano-clay, nano-silica, and nano-alumina, which are uniformly dispersed in the polymer matrix to enhance barrier properties and the mechanical strength of the material.

[0008] Preferably, the inorganic barrier coating is made of inorganic alumina material, which can form a dense and highly barrier inorganic barrier to prevent the permeation of gas and moisture and improve the barrier performance of the blister aluminum.

[0009] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0010] This invention utilizes a heat-sealing coating made of polypropylene, ensuring that the aluminum blister pack easily forms a tight and durable seal during packaging. The reinforcing adhesive coating, made of polyurethane and positioned above the heat-sealing coating, significantly improves the adhesion between the layers and the overall structural stability. The excellent adhesion and elasticity of polyurethane allow the aluminum blister pack to resist impacts and vibrations from the external environment, avoiding the risk of coating peeling or cracking, thus maintaining its superior barrier properties.

[0011] This invention provides an additional protective barrier for the blister pack aluminum by adding an anti-corrosion coating, effectively preventing the corrosion of harmful substances such as oxygen and water vapor, and greatly extending the service life of the blister pack aluminum. The high-barrier polymer coating, located on the lower surface of the thin aluminum sheet, plays a crucial role. This coating is made of a material with high barrier properties, which can effectively block the penetration of oxygen and water vapor, ensuring that the items inside the packaging remain fresh and dry.

[0015] Please see Figure 1 One embodiment of this utility model is a tropical-type blister aluminum with high barrier properties, comprising a thin aluminum sheet layer 1, a thin...

[0016] A heat-sealing coating 5 is fixedly provided on the upper surface of the aluminum sheet layer 1, and an enhanced adhesive coating 6 is fixedly provided on the upper surface of the heat-sealing coating 5. An anti-corrosion coating 7 is fixedly provided on the upper surface of the enhanced adhesive coating 6. A high-barrier polymer coating 2 is fixedly provided on the lower surface of the thin aluminum sheet layer 1, and a nano-composite coating 3 is fixedly provided on the lower surface of the high-barrier polymer coating 2. An inorganic barrier coating 4 is fixedly provided on the lower surface of the nano-composite coating 3.

[0017] Furthermore, the heat-sealing coating 5 is made of polypropylene material to ensure good heat-sealing performance and sealing strength, ensuring that the blister aluminum packaging can effectively prevent the contents of the packaging from being contaminated by the external environment during manufacturing and use.

[0018] Furthermore, the reinforcing adhesive coating 6 is made of polyurethane material to improve the adhesion between coatings and the stability of the overall structure, thereby effectively resisting the impact and vibration of the external environment and preventing the coating from peeling off or cracking.

[0019] Furthermore, the nanocomposite coating 3 contains nano-clay, nano-silica, and nano-alumina. These nanoparticles are uniformly dispersed in the polymer matrix to enhance barrier properties and the mechanical strength of the material. This enhances the barrier properties of the blister aluminum, enabling it to effectively block the penetration of harmful substances such as oxygen and water vapor, and also improves the mechanical strength of the material.

[0020] Furthermore, the inorganic barrier coating 4 is made of inorganic alumina material, which can form a dense and highly barrier inorganic barrier to prevent the permeation of gases and moisture, improve the barrier performance of the blister aluminum, and ensure that the blister aluminum can maintain its excellent barrier performance when facing harsh climatic conditions and chemical environments, so as to ensure that the items inside the packaging are not damaged.

[0021] Working principle: First, the heat-sealing coating 5 is made of polypropylene, ensuring that the blister aluminum forms a tight and durable seal during the packaging process. This heat-sealing coating not only has excellent heat-sealing performance but also provides sufficient seal strength to prevent the contents of the package from being contaminated by the external environment.

[0022] Next, the reinforcing adhesive coating 6, made of polyurethane, sits atop the heat-sealing coating 5. Its main function is to improve the adhesion between the coatings and the overall structural stability. Polyurethane has excellent adhesion and elasticity, effectively resisting the impact and vibration of the external environment, ensuring that the aluminum blister will not have its barrier properties affected by coating peeling or cracking during use.

[0023] The anti-corrosion coating 7 sits atop the reinforcing adhesive coating 6, providing additional corrosion protection for the blister aluminum. This coating effectively prevents harmful substances such as oxygen and water vapor from corroding the blister aluminum, extending its service life.

[0024] Beneath the thin aluminum sheet layer 1, the high-barrier polymer coating 2 plays a crucial role. Made of a material with high barrier properties, it effectively prevents the penetration of oxygen, water vapor, and other substances, ensuring the contents of the package remain fresh and dry. Simultaneously, the high-barrier polymer coating also possesses good flexibility and abrasion resistance, enabling it to adapt to various packaging needs.

[0025] The nanocomposite coating 3 lies beneath the high-barrier polymer coating 2 and contains nanoparticles such as nano-clay, nano-silica, and nano-alumina. These nanoparticles are uniformly dispersed in the polymer matrix, forming a dense nanocomposite structure that further enhances the barrier properties and mechanical strength of the blister aluminum.

[0026] Finally, the inorganic barrier coating 4, as the bottom layer, is made of inorganic alumina. It forms a dense and highly barrier-free inorganic barrier that prevents the permeation of gases and moisture, thereby improving the barrier performance of the blister aluminum.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
