How to Make Aluminum Bottle Packaging for Cosmetics?

While perfumes do not spoil as quickly as food, most of them experience a noticeable decrease in fragrance intensity within six months. Therefore, understanding that perfume bottles are not just containers for liquid is crucial. An ideal perfume bottle not only enhances the brand's appeal but also effectively protects the perfume. Perfumes need to be stored in packaging that shields them from light, temperature, oxidation, and air, as these factors often accelerate the deterioration of fragrances.

• Step 1: Selecting Quality Aluminum Sheets

Aluminum bottles are initially made from a round aluminum sheet, so selecting a high-quality sheet is crucial as it directly determines the final quality of the aluminum bottle. The aluminum sheet needs to meet standards for strength, purity, and pliability.

• Step 2: Making Aluminum Cylinders

Lubricate the stamping machine and place the aluminum sheet into the corresponding mold. Start the stamping machine to form a cylindrical shape, which serves as the basic structure of the aluminum bottle. During this process, it's important to note that if you want to make a bottle with a specific diameter, you need to use corresponding diameter aluminum sheets and molds. Additionally, consideration should be given to the proportion of diameter to height to ensure the bottle looks proportionate and to the weight of the bottle, as it indicates the thickness of the bottle walls. If you want to create a special shape at the bottom of the bottle or engrave a brand logo, special molds are required.

• Step 3: Making Bottle Necks

After obtaining the aluminum cylinder, the next step is to use a necking machine to shape the top into a beautiful curved shoulder and round bottle neck. You can customize the shoulder shape, which can be full-rounded, concave, or conical. Also, you can customize the size of the bottle neck to match accessories like caps and pumps that will be used later. This process involves cutting off excess material from the top of the bottle.

• Step 4: Cleaning Aluminum Bottles

During the production process, lubricating oil or other residues, even metal fragments, may adhere to the surface of aluminum bottles. Therefore, it's necessary to clean and dry the inside and outside of the bottles using a bottle washing machine. The liquid used for cleaning aluminum bottles is a special chemical agent that effectively removes lubricating oil and other residues. This is followed by a rinse with pure water generated by a reverse osmosis device and heated. When cleaning with chemical agents, attention should be paid to controlling the cleaning time, as excessive time can cause whitening of the bottle surface, while too short a time may not thoroughly clean oil stains, leading to a dull appearance. Properly controlling the cleaning time can result in a brighter surface. Once cleaning is complete, the bottles are dried.

• Step 5: Making Bottle Thread

After cleaning, a crucial step is to create bottle threads, which determine whether the bottle can perfectly match other accessories like caps and pumps, thus avoiding the risk of leakage during use. Thread making can be deep or shallow, coarse or fine, depending mainly on the threads of the accessories. If aluminum caps are to be used with the bottles, the threads are relatively coarse and shallow, while if plastic pumps, sprayers, and other accessories are needed, the threads should be made as fine and deep as possible.

• Step 6: Exterior Polishing

The surface of aluminum bottles formed by stamping often has distinct vertical scratches. To improve the appearance of aluminum bottles, most brands prefer to polish them to obtain a smoother surface. The polishing process is straightforward and involves using a polishing machine to polish the bottles.

• Step 7: Interior Coating

If aluminum bottles are to be used to contain corrosive liquids or food-grade beverages, an interior coating is needed to protect the bottles and prevent chemical reactions between the aluminum material and the liquid contents, which could lead to product deterioration. Coatings can be industrial-grade or food-grade, with epoxy resin coating being a representative industrial-grade coating, typically yellow in color and used for corrosive industrial products, while food-grade coatings are more commonly used in the food and beverage industry.

• Step 8: Exterior Painting/Anodizing

If higher surface treatment requirements are needed for aluminum bottles, such as complex colors and printing, painting and anodizing are required. Paints used for painting can be transparent clear varnish or colored paints, with glossy or matte textures, making the painted aluminum bottles more attractive. Sometimes, even without printing, a clear varnish can be applied to improve the surface effect and feel. Anodizing is an electrolytic process that forms a protective oxide layer on the surface of aluminum bottles. This oxide layer can have special colors and a strong metallic texture, while also improving the abrasion resistance and corrosion resistance of the aluminum bottles.

• Step 9: Exterior Printing/Labeling

For most brands, printing their logos or patterns on aluminum bottles helps their products stand out in the competitive market. Printing methods include simple silk-screen printing, hot stamping, as well as more complex heat transfer printing and 3D printing, with the cost increasing with the complexity of the printing process. If the printing content is very complex, label stickers can be used to control costs.

• Step 10: Bagging Packaging

After completing all the production processes mentioned above, the final but equally important step is bagging and packing. Although aluminum bottles are less prone to breakage than glass bottles, they are still susceptible to scratches, dents, and deformation, especially when subjected to severe impacts. Therefore, proper packaging to protect aluminum bottles is necessary.


Tips: The cap accessories for aluminum bottles include ordinary aluminum caps and plastic anti-theft caps. If plastic anti-theft caps are used, the bases of the anti-theft caps need to be installed and fixed on the bottle necks using machines.
