What characteristics does the Aluminum Plastic Fragrance Lid use to achieve the waterproof and moisture-proof effect?

As a packaging component designed specifically for cream products, the Aluminum Plastic Fragrance Lid achieves its waterproof and moisture-proof effect through a variety of factors. First of all, in terms of material, the Aluminum Plastic Fragrance Lid uses two different layers of materials, namely the plastic inner cover and the aluminum oxide outer cover.
The plastic inner cover is the first layer of protection for the Aluminum Plastic Fragrance Lid. As a common packaging material, plastic has a certain waterproof performance. In the Aluminum Plastic Fragrance Lid, the plastic inner cover is designed to fit tightly to the mouth of the product container, which can effectively prevent external moisture from entering the package through the gap. This tight fitting design not only improves the sealing of the packaging, but also ensures the safety of the product during transportation and storage.
The aluminum oxide outer cover is the second layer of protection for the Aluminum Plastic Fragrance Lid. Aluminum oxide, as a high-performance material, has excellent moisture resistance and corrosion resistance. In the Aluminum Plastic Fragrance Lid, the aluminum oxide outer cover is carefully crafted, and its surface undergoes a special oxidation treatment process, making it harder and more wear-resistant, and can effectively isolate external moisture and air. This special oxidation treatment process not only improves the durability of the aluminum oxide outer cover, but also further enhances its waterproof performance.
In addition to the choice of materials, the design of the aluminum-plastic perfume cover also fully considers the needs of waterproofing and moisture-proofing. In terms of structure, the aluminum-plastic perfume cover adopts a tight design to ensure that there is no gap at the connection between the inner and outer covers. This tight design can effectively prevent moisture from entering the interior of the package through the gap, thereby ensuring the dryness and quality of the product.
In addition, the aluminum-plastic perfume cover may also undergo special waterproof treatment processes during the production process. These treatment processes may include adding a waterproof coating between the plastic inner cover and the aluminum oxide outer cover, and performing surface waterproof treatment on the aluminum oxide outer cover. These treatment processes can further enhance the waterproof performance of the aluminum-plastic perfume cover, making it more adaptable to humid environments.
