CAPACITY & CUSTOMIZATION
Furthermore, the 500ml capacity helps reduce the frequency of refilling, while allowing the container to serve as a ready-to-use dispenser placed directly on countertops or tables.
Being an OEM/ODM dedicated to providing packaging, we can utilize brand identity solutions such as labeling, printing, and hot stamping in accordance with your design needs. Also, we offer various options for pump head colors, lock systems, and caps in order to fulfill both aesthetic and shipping requirements.

Foam Pump vs. Standard Liquid Pump: Two Ways to Dispense Hand Wash
A foam pump is not an upgraded version of a standard liquid pump. The two are designed for different hand wash formulas and dispensing methods. The choice mainly depends on whether the product should reach the user as a liquid or as ready-made foam.
|
Comparison |
Standard Liquid Pump |
Foam Pump |
|
Dispensed form |
Dispenses the hand wash directly in its original liquid form. |
Mixes the liquid formula with air during dispensing to produce foam. |
|
Formula type |
Better suited to hand wash formulas with a thicker liquid texture. |
Better suited to lower-viscosity hand wash formulas developed specifically for foaming. |
|
How it is used |
The user dispenses the liquid, adds water, and creates foam by rubbing the hands together. |
The user receives foam directly from the pump before washing and rinsing. |
|
Role of the pump |
Draws the liquid from the bottle and dispenses a measured amount. |
Draws in both liquid and air, mixes them inside the pump, and dispenses the product as foam. |
|
When to choose it |
When the product should retain its original liquid texture or is not suitable for a foam pump. |
When the hand wash is formulated to be dispensed directly as foam. |
For hand wash formulas developed to be dispensed as foam, choosing a 500ml PET foam pump bottle for hand wash keeps the packaging format consistent with the formula and intended use. The 500ml also provides more product for regular use, helping reduce how often the bottle needs to be refilled or replaced. This makes it a practical option for frequently used foaming hand wash products.
Packaging Studio: Moving from traditional liquid pumps to 500ml foam pump packaging
01. Customer Profile
A personal care brand wanted to modernize its existing hand soap, sold in a 500 ml family size. Its existing hand wash range used standard PET bottles with lotion pumps, but the upgrade product was intended to dispense foam as soon as the pump was pressed.
Our client wanted to keep the 500ml size and the same color and design as the original handwash product. They don't want to start from scratch and redesign completely new bottle shapes and label designs.
02. Project Challenge
Initially, the client planned simply to replace the existing pump with a foam pump on the original 500 ml bottle; however, the bottle's neck structure proved incompatible with commercially available foam pumps.
Developing a new bottle mold would not only have increased the initial investment and development time but would also have required adjustments to the original graphic design. Furthermore, the client needed to verify whether the existing formula was suitable for foam dispensing, as changing the pump mechanism does not guarantee that the original liquid formula will produce foam meeting the required standards.
03. Our Packaging Solution
To avoid the need to develop a new mold, we selected an existing 500 ml bottle equipped with a foam pump. During the selection process, we considered criteria such as the bottle's proportions, the front display area, the ability to retain the original layout, and the pump's compatibility with the client's formula.
Once the bottle was chosen, we compared various pump models based on performance: initial foam output, dosage per stroke, smoothness of continuous pumping, and the responsiveness of the return mechanism. We then considered how the filled package would be handled during transport. To reduce the risk of accidental dispensing, the final solution used a lockable 500ml foam pump bottle. The locking mechanism kept the actuator in place during handling and shipping. Aesthetically, the new bottle retains proportions and a front display area similar to the original packaging. This allows the client to adapt their existing logo, product name, and layout rather than redesigning everything from scratch. The pump color can either maintain continuity with the current product line or serve to distinguish this new foaming version.
The final solution consists of a 500 ml bottle with a foam pump and locking system; this approach avoids the costs associated with creating new tooling while preserving the brand's original visual identity.
04. Solution Outcome
15.1%
INCREASE IN THE PURCHASE CONVERSION RATE
The client retained the original 500 ml capacity while evolving the product, switching from standard liquid pump packaging to a foam-dispensing format.
By opting for an existing foaming pump bottle model, the client avoided the need to develop a new mold. The logo, product name, and original layout were also preserved, requiring only minor adjustments to fit the new bottle body.
The final 500ml PET Foam Dispenser Bottles solution resolved the neck compatibility issue while keeping the updated package visually connected to the original hand wash range. Following the launch, the brand recorded a 15.1% increase in the purchase conversion rate compared to the previous packaging.
From A Single Product To A Full Range
As soon as the design for the first product is finalized, the same bottle design could also be used for a range of foaming hand soaps manufactured in different scents or with various functional characteristics. The brand only needs to make different versions of the same bottle design by changing colors, printing, and pump but will not have to get new packaging for every new product version.
When it comes to foaming hand soap brands that use foaming pump bottles, it is possible to use the same bottle design and shape for all products while still giving them different colors and designs.
