Outer Bottle Design: the outer bottle of Double Wall Airless Pouch Bottle is equipped with ventilation holes, which are connected to the inner cavity of the outer bottle. This design ensures that the air pressure inside and outside the outer bottle remains balanced during the shrinkage of the inner bottle, preventing the inner bottle from deforming or breaking.
Inner Bottle Function: The inner bottle shrinks as the filler decreases. This self-priming design ensures that the product inside the bottle is fully utilised during use, ensuring that every drop of product can be used effectively and minimising waste.
Reduces Product Residue:
Full Utilisation: consumers can make full use of the product they have purchased. This double wall design significantly reduces product residue compared to conventional lotion bottles.
Disadvantages of Conventional Lotion Bottles: Conventional lotion bottles usually come with a draw tube dispensing pump that leaves residue at the bottom of the bottle after use. In contrast, the PA140 Airless Cosmetic Bottle Inner Capsule Bottle has a self-priming design (no suction back) that ensures product exhaustion and reduces residue.
