Description

Tropical type bubble cap aluminum with high barrier property Technical Field The utility model relates to the technical field of tropical bubble cap aluminum, in particular to tropical bubble cap aluminum with high barrier property. Background The tropical bubble cap aluminum material is widely applied to various packaging industries such as medicines, foods, cosmetics and the like by virtue of the characteristics of portability, strong plasticity, good appearance and the like. However, while these conventional blister aluminum materials perform well in conventional environments, limitations in barrier properties are revealed in the face of high temperature, high humidity climatic conditions. Under extreme climatic conditions, conventional blister aluminum materials often have difficulty effectively blocking permeation of harmful substances such as oxygen, water vapor, and the like due to dual effects of temperature and humidity. Such permeated oxygen and water vapor not only reduce the shelf life of the contents of the package, but also easily induce chemical reactions, which cause deterioration, damage, and even the generation of substances harmful to the human body. Thus, conventional blister aluminum materials clearly have failed to meet the barrier properties requirements for articles that require long-term storage or transport in tropical regions. Disclosure of utility model The utility model provides a tropical formula bubble cap aluminium with high barrier property, includes the aluminum flake layer, the fixed heat-seal coating that is equipped with in upper surface layer on aluminum flake layer, and the fixed enhancement bonding coating that is equipped with in upper surface layer on heat-seal coating, the fixed anticorrosion coating that is equipped with in upper surface layer on enhancement bonding coating, the fixed high barrier polymer coating that is equipped with in lower surface layer on aluminum flake layer, and the fixed nanocomposite coating that is equipped with in lower surface layer on high barrier polymer coating, nanocomposite coating's lower surface layer is fixed and is equipped with inorganic barrier coating. Preferably, the heat seal coating is made of polypropylene material to ensure good heat seal performance and seal strength. Preferably, the adhesion-enhancing coating is made of a polyurethane material to improve adhesion between the coatings and stability of the overall structure. Preferably, the nanocomposite coating comprises nanoclays, nanosilicas, or the like, which are homogeneously dispersed in the polymer matrix to enhance barrier properties and mechanical strength of the material. Preferably, the inorganic barrier coating is made of inorganic alumina material, so that a layer of compact and high-barrier inorganic barrier can be formed, gas and moisture permeation is prevented, and barrier performance of the aluminum bubble cap is improved. From the above technical scheme, the application has the following beneficial effects: The utility model ensures that the bubble cap aluminum can easily form tight and durable seal in the packaging process by adopting the polypropylene material for the heat seal coating. The polyurethane material is used for the reinforcing bonding coating and is positioned on the heat sealing coating, so that the bonding force between the coatings and the stability of the whole structure are obviously improved. The excellent adhesive property and elasticity of polyurethane enable the aluminum bubble cap to resist the impact and vibration of the external environment, avoid the risk of falling off or cracking of the coating, and maintain the excellent barrier property. According to the utility model, through the addition of the anti-corrosion coating, an additional protective barrier is provided for the aluminum bubble cap, so that the corrosion of harmful substances such as oxygen, water vapor and the like is effectively prevented, the service life of the aluminum bubble cap is greatly prolonged, and the high-barrier polymer coating is positioned on the lower surface layer of the aluminum thin sheet layer, so that a vital effect is achieved. The coating is made of a material with high barrier property, can effectively block permeation of oxygen, water vapor and the like, and ensures that the articles in the package are kept fresh and dry.
