Double wall airless pump jars use airless technology to protect sensitive cosmetic formulas. The inner chamber and outer chamber work together to limit oxidation and product exposure. This double‑wall construction supports face creams, lotions, night masks, and other skincare products. The airtight seal and vacuum system allow a precise dosage while reducing waste.
Injection molding techniques for double wall airless pump bottles
Manufacturers use injection molding to create the inner jar, outer wall, and lotion pump. Materials such as PMMA plastic, HDPE, PET, PP, aluminum, and stainless steel offer strength and safety. Acrylic double wall airless pump containers can feature frosted, matte, satin, semi‑gloss, or glossy surfaces. Transparent caps, transparent overcaps, twist locks, clip locks, and black child proof caps are also made during this step.
Assembly of the airless dispensing system
Next, teams assemble the plunger, dip tube, dispensing nozzle, air intake holes, and press‑down dispensing system. This setup forms an airtight seal and supports hygienic dispensing. It protects formula stability by reducing air contact. It also lowers contamination risks. Many packaging options use materials that break down naturally. They also use recyclable materials. This helps meet sustainability goals and ensures proper disposal.
Surface finishing and custom graphics
Manufacturers then apply silk screen printing, silk screen graphics, hot stamp effects, PMS color matching, and embossed printing. These methods allow broad customization options for cosmetic products. Transparent caps, frosty looks, matte tones, or glossy finishes help match different cosmetic packaging solutions. Private molds and labeling and printing technologies create unique designs for jars and bottles.
Material selection for durability and safety
Materials like PET, PP, HDPE, aluminum, PMMA plastic, and acrylonitrile styrene copolymers work safely with many cosmetic formulas. These materials make recycling easier. These materials also meet environmental rules. Some options include UV‑resistant, flame‑retardant, or ozone‑resistant features. Reusable containers and reusable bottles help reduce product waste and support better recycling habits.
