Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic blister shells, in particular to an anti-corrosion, grease-resistant and lightweight plastic blister shell. Background Technique
[0002] Lightweight plastic blister shells are usually made of polypropylene. These materials are lightweight, impact-resistant and easy to process, and are suitable for various packaging requirements.
[0003] Although materials such as polypropylene commonly used in plastic blister shells have the advantages of light weight and easy processing, they have poor tolerance to oils and chemicals. These materials will be eroded by oils, solvents or other chemicals, resulting in the deterioration of physical properties. The surface of its plastic blister shell usually has large pores and textures, and these structures will adsorb oils or other pollutants, reducing its cleanliness and durability. At the same time, lightweight plastic materials are easy to absorb oils, which will lead to a decrease in the strength and toughness of the materials, and will also affect the appearance and function of the blister shell. The chemical stability of polystyrene and polypropylene is relatively low, and they have weak resistance to oils and corrosive chemicals. Oils will cause the expansion, deformation or degradation of the materials, resulting in unusability. In order to solve the above problems, we propose an anti-corrosion, grease-resistant and lightweight plastic blister shell. Summary of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Embodiment: As Figures 1-5 shown, the present utility model provides a corrosion-resistant, grease-resistant and lightweight plastic blister shell, including a base layer 1 made of polystyrene. Grease-resistant layers 3 for enhancing the overall grease tolerance are provided on both sides of the base layer 1, and the two grease-resistant layers 3 are symmetrically distributed along the axis of the base layer 1. Corrosion-resistant layers 4 for enhancing the overall chemical stability are provided on the end faces of the two grease-resistant layers 3 away from each other, and the two corrosion-resistant layers 4 are symmetrically distributed along the axis of the base layer 1. The base layer 1, the grease-resistant layer 3 and the corrosion-resistant layer 4 together form the plastic blister shell body 5. A card seat 2 for closing the shell is formed on the surface of the plastic blister shell body 5. The polystyrene base layer 1 is lightweight, making the plastic blister shell easy to handle and use. With corrosion resistance and grease resistance and wide applicability, it can be used to package various products sensitive to grease and chemicals, such as food, cosmetics, drugs, etc., to prevent the products from being affected by the external environment, ensure the quality and safety of the products, reduce the packaging breakage rate caused by corrosion and grease erosion, and reduce product losses. During packaging and transportation, operators can easily handle and process the plastic blister shell, improving work efficiency. The lightweight feature enables more blister shells to be stacked during storage and transportation, saving space and transportation costs. The card seat 2 is designed with good sealing performance, which can effectively seal the plastic blister shell, prevent dust, moisture and other impurities from entering, ensure the cleanliness and hygiene of the products, and is easy to open and close, improving the convenience of use of the packaging.
[0025] Multi-layer distribution with clear functions. Each layer undertakes different functions respectively. The base layer 1 provides basic structural support. The grease-resistant layer 3 and the corrosion-resistant layer 4 respectively enhance the grease tolerance and chemical stability. The materials and thicknesses of each layer can be adjusted according to different requirements to achieve the best packaging effect. The multi-layer structure cooperates with each other and functions together.
[0026] Among them, the grease-resistant layer 3 includes polyvinyl fluoride 301, polyurethane 302 and fluorinated polymer 303. Polyvinyl fluoride 301 is arranged on both sides of the base layer 1. The end faces of polyvinyl fluoride 301 on both sides away from each other are compounded and adhered to polyurethane 302. Fluorinated polymer 303 is arranged on the side of polyurethane 302 away from polyvinyl fluoride 301. Polyvinyl fluoride 301, polyurethane 302 and fluorinated polymer 303 are arranged and distributed in sequence along the direction away from the base layer 1. Polyvinyl fluoride 301 has excellent chemical corrosion resistance, has strong resistance to a variety of acids, alkalis, organic solvents, etc., has a low surface energy, making it difficult for grease to adhere, thus showing good grease resistance, and has relatively high mechanical strength, which can provide certain structural support for the entire grease-resistant layer 3. Polyurethane 302 has good flexibility and elasticity, can adapt to the packaging of products with different shapes, provides buffer protection, has a certain barrier effect on grease, and can enhance the grease resistance performance when combined with polyvinyl fluoride 301, and has good bonding performance, which can effectively bond polyvinyl fluoride 301 and fluorinated polymer 303 firmly together. Fluorinated polymer 303 has extremely high chemical stability, has strong tolerance to almost all chemical substances, has a smooth surface, and grease is not easy to adhere, further improving the overall grease resistance performance, and has good heat resistance and cold resistance, and can maintain stable performance in different temperature environments. The advantages of the overall distribution are progressive protection. Polyvinyl fluoride 301, as the layer in direct contact with the base layer 1, first exerts its characteristics of chemical corrosion resistance and low surface energy to block the erosion of the base layer 1 by grease. Polyurethane 302 plays a buffering and enhancing bonding role in the middle, and at the same time further improves the grease resistance. Fluorinated polymer 303 is on the outermost layer. With its extremely high chemical stability and smooth surface, it provides the strongest protection for the entire grease-resistant layer 3. The characteristics of the three materials complement each other and function together. The combination of the corrosion resistance of polyvinyl fluoride 301, the flexibility of polyurethane 302 and the chemical stability of fluorinated polymer 303 makes the grease-resistant layer 3 have more comprehensive performance. The combination of different materials can be adjusted according to actual needs to meet the packaging requirements of different products and improve the overall performance. This distribution method makes the performance of the grease-resistant layer 3 more stable and reliable.
[0027] The corrosion-resistant layer 4 includes epoxy resin 401, acrylic paint 402, and polyamide coating 403. The epoxy resin 401 is disposed on both sides of the base layer 1, and the epoxy resins 401 on both sides are symmetrically distributed along the axis of the base layer 1. The side of the epoxy resin 401 on both sides close to the base layer 1 is in contact and adhered to the fluoropolymer 303. The side of the epoxy resin 401 away from the fluoropolymer 303 is in contact with the acrylic paint 402. The side of the acrylic paints 402 on both sides away from the epoxy resin 401 is in contact and adhered to the polyamide coating 403. The epoxy resin 401, acrylic paint 402, and polyamide coating 403 are arranged and distributed in sequence along the direction away from the base layer 1 of the oil-resistant layer 3. The good adhesion of the epoxy resin 401 can firmly adhere to the fluoropolymer 303, providing a stable foundation for the corrosion-resistant layer 4. It has chemical corrosion resistance and strong resistance to a variety of chemical substances, effectively preventing the erosion of chemical substances on the blister shell. It has a relatively high hardness and can provide a certain mechanical strength for the entire corrosion-resistant layer 4. The acrylic paint 402 has good weather resistance, can resist the influence of natural factors such as ultraviolet rays and temperature changes, maintaining the stability of the corrosion-resistant performance. It has good flexibility and is not easily broken when subjected to external forces, and can adapt to the shape change of the blister shell. It has a certain decorative property and can make the surface of the plastic blister shell more beautiful. The polyamide coating 403 has strong wear resistance, can resist friction and abrasion, protecting the corrosion-resistant layer 4 from being damaged. It has excellent corrosion resistance, high tolerance to chemical substances such as acids, alkalis, and salts, and good waterproof performance, which can prevent moisture from penetrating into the interior of the blister shell, further improving the corrosion-resistant performance;
[0028] Multiple protections: The epoxy resin 401, as the first layer, is tightly combined with the fluoropolymer 303, laying the foundation for the corrosion-resistant layer 4 and blocking the intrusion of chemical substances. The acrylic paint 402 is in the middle. Utilizing its weather resistance and flexibility, it enhances the stability and adaptability of the corrosion-resistant layer 4. The polyamide coating 403 is on the outermost layer. Relying on its wear resistance, corrosion resistance, and waterproof performance, it provides the strongest protection for the entire corrosion-resistant layer 4. Complementary properties: The properties of the three materials complement each other and work together. The adhesion and chemical corrosion resistance of the epoxy resin 401, the weather resistance and flexibility of the acrylic paint 402, and the wear resistance and waterproof performance of the polyamide coating 403 are combined, making the corrosion-resistant layer 4 have more comprehensive performance. The combination of different materials can be adjusted according to actual needs to meet the corrosion-resistant requirements in different usage environments, improving reliability. This distribution method makes the performance of the corrosion-resistant layer 4 more stable and reliable. Even if a slight damage occurs in a certain layer, the other layers can still continue to function, ensuring the corrosion-resistant performance of the packaging, contributing to improving the overall service life and packaging quality of the plastic blister shell, and reducing the risk of product damage due to packaging corrosion.
