The Production Process for Airless Bottle Cosmetic Packaging

The Production Process for Airless Bottle Cosmetic Packaging

Airless Bottle are a stylish cosmetic packaging solution for cremes, lotions and skincare products. They come with a unique non-pressurized vacuum design that provides numerous benefits in functionality.

When you push down on the pump, a disc inside the bottle moves up slightly. This causes your product to dispense evenly.

Injection Molding

Injection molding is the process by which plastic is injected into a mold to create a finished product. The injection molding process requires careful planning and attention to detail in order to produce high-quality products.

The first step in the injection molding process is to fabricate the tooling. This involves taking a metal block and using a CNC mill to carve out a negative of the final plastic part. This is a highly precise process, as the final part must be perfectly accurate to ensure that the bottle meets all specifications.

Once the tooling is complete, it is installed in an injection machine. The machine is then filled with a heated plastic material, and the molten plastic is forced into the cavities of the mold by a nozzle. The injection pressure must be carefully controlled to pump with piston avoid causing damage to the product or early solidification of the molten plastic in the mold channels.

A family mold is a type of injection molding machine that allows for the production of multiple different bottle designs within one machine. This reduces assembly time, and can help manufacturers save money and increase productivity. Injection molding is also an environmentally conscious manufacturing method, as it produces fewer emissions than other plastics manufacturing methods. This is especially important for airless bottles, which are designed to be used in a wide variety of environments and conditions.

Assembly

Cosmetic products require special packaging to protect their formulations and ingredients from contamination, oxidation, and other environmental factors. Airless bottles are ideal for this purpose, as they isolate the product inside to prevent air exposure. This is especially important for skincare solutions that contain oxygen-sensitive ingredients, such as retinol (Vitamin A) and Vitamin C, which can suffer from deterioration and oxidation when exposed to the environment.

The assembly process involves carefully positioning and fitting all components of the bottle, including the pump mechanism. This ensures that the pumps are properly positioned and sealed to guarantee that no air enters or escapes during the dispensing process. The pump is incorporated into the bottle body, with a vented space 14 and a vacuum space 15 isolated by an airtight ring portion 131 on the piston 13. When the piston is activated, it moves upward and creates a pressure difference between the vented space and the vacuum space, which draws the product out of the vent hole and into the dispenser.

After the assembly is complete, each bottle undergoes rigorous testing to ensure that it functions correctly and meets industry standards for safety and hygiene. These tests include assessing the seals for leaks and verifying that they can withstand pressure differentials and temperature fluctuations, which simulate real-world conditions. These tests also involve examining the bottles’ durability and resistance to external damage.

Labeling

The labeling process is a vital part of the cosmetic packaging production chain. Once the bottles pass rigorous quality control tests, they are ready to receive labels that contain product information and necessary warnings or instructions. Labels are typically pump with piston applied using various printing techniques, including silk screening and hot stamping. The choice of adhesive is also important. For example, soft-touch bottle labels require an aggressive permanent adhesive to achieve full adhesion. Labels that are printed on clear film require an ultra-clear permanent adhesive to ensure a high-quality appearance.

Airless bottle packaging offers excellent protection against moisture, grease, oil, heat, and alcohol, making it an attractive option for cosmetic products that need to stay fresh and unadulterated until they are opened by the consumer. This is particularly true for high-end beauty products that incorporate sensitive formulations or ingredients that may require specific environmental conditions to maintain their quality and efficacy.

Additionally, a growing number of brands are requesting airless packaging for their products that are formulated with ingredients that are oxygen-sensitive. This includes products with retinol, Vitamin C, and other powerful antioxidants that are vulnerable to oxidation and decomposition when exposed to air. This type of protection is possible with airless dispensing systems that isolate the formula from outside elements, allowing the user to apply precise product doses.

Packaging

Packaging is an integral part of the production process for beauty products. It protects the product from damage and ensures that it stays fresh and secure until the moment it is used. In addition, it conveys a sense of luxury and high-end quality that is essential for establishing a strong brand image.

To meet this demand, manufacturers use advanced techniques to deliver premium quality. They use high-grade materials, such as PET and PP, to ensure that the bottles are durable and hygienic. They also offer eco-friendly, refillable options to reduce plastic waste.

Airless bottle packaging keeps the cosmetic product shielded from air until it is dispensed, preserving its quality and extending its shelf life. This makes it an ideal choice for organic and high-performance products that contain sensitive ingredients. Additionally, it is a more hygienic packaging option than basic dispensing solutions that require consumers to dip their fingers into the product.

During the design phase, skilled designers work with clients to create a stylish and functional bottle. They consider factors such as ergonomics, branding elements, and the desired dispensing mechanism. Additionally, they incorporate color and pattern options to add an attractive finishing touch to the bottle. They also utilize advanced printing techniques to achieve a beautiful and consistent finish. Silkscreen printing, for example, is an excellent choice for transferring intricate patterns and fine details onto the bottle’s surface.
