When I work on a Cosmetic Packaging project, I do not look at the bottle from appearance alone. A package needs to look right, but it also needs to be practical during filling, comfortable in daily use, suitable for the product inside, and stable enough for transportation. That is especially true when a brand plans to move from a small sample order to regular mass production.

Our 15ml 30ml 50ml Double-layer AS Plastic Airless Bottle is designed around these practical needs. It combines an AS plastic structure, a double-layer bottle body and an airless dispensing system. Three capacity options—15ml, 30ml and 50ml—give Cosmetic Brands more flexibility when selecting packaging for different skincare and beauty products.

AS plastic is also interesting from a visual point of view. The material can provide a clear and clean appearance, which is often useful for modern cosmetic packaging designs. At the same time, the double-layer structure gives the bottle a more distinctive visual form than a simple single-wall package.

At Yuyao Dingyu Plastic Industry Co., Ltd., we manufacture cosmetic packaging in our own factory in Yuyao, Ningbo, Zhejiang Province. Our factory covers about 5,000 square meters and includes mold development workshops, injection-molding machines and testing instruments. Airless Cosmetic Bottles are our flagship products, supported by lotion bottles, perfume bottles, PET bottles and other beauty packaging solutions.

1. What Is a Double-layer AS Plastic Airless Bottle?

A Double-layer AS Plastic Airless Bottle is a cosmetic packaging container that combines AS plastic components with a double-layer bottle body and an airless dispensing structure.

The product is available in 15ml, 30ml and 50ml capacities. These sizes can be considered for different types of skincare and beauty products, including serums, lotions, creams, emulsions and other personal care formulations.

The AS material gives the bottle a clear or clean visual character, while the double-layer construction creates an additional visual element around the bottle body. The final appearance can also be customized through different decoration methods depending on the project.

The airless part of the design is mainly related to dispensing. Instead of opening a wide container and taking the product out manually, the user operates the Pump to dispense the product.

I want to make one point clear here because it matters when selecting cosmetic packaging: an airless bottle should not automatically be described as a guarantee of longer shelf life or complete protection against oxidation. The actual protection of a cosmetic formula depends on the formulation, package construction, filling conditions, storage and other factors.

What an airless structure can provide is a controlled dispensing format and, depending on the design, reduced direct exposure of the remaining product to outside air during normal use.

2. How Does the Airless Dispensing System Work?

The airless principle is easier to understand than the name makes it sound. The main idea is to use a pump and internal dispensing structure to move the cosmetic product toward the outlet as the user operates the pump.

When the pump is pressed, the dispensing mechanism delivers a measured amount of product through the outlet. Depending on the specific package design, an internal piston or similar moving component may rise as the product is dispensed.

The exact internal construction can vary, so I do not describe every airless bottle as having exactly the same mechanism. What matters is that the package is designed around controlled dispensing rather than simply exposing a large amount of product every time the container is opened.

Why Does Controlled Dispensing Matter?

For daily skincare use, convenience matters. A customer normally wants to press the pump, get the product and continue with their routine. A pump format can also help avoid repeatedly touching the remaining product with fingers.

This can be especially useful for face creams, serums and lotions that are used frequently.

For cosmetic brands, there is another practical benefit. A pump can give the package a consistent user experience. Of course, actual dose consistency depends on the pump design, product viscosity and how the customer operates it, so this should be tested rather than assumed.

Airless Does Not Mean Formula Compatibility Is Automatic

This is one of the most important points I tell customers. Even if the bottle works perfectly with one lotion, it does not mean that the same package will perform identically with a very thick cream or a different serum.

Viscosity, formulation characteristics and filling conditions can affect dispensing. That is why we support sample testing before mass production.

3. 15ml, 30ml or 50ml: Which Capacity Fits Your Product?

Choosing capacity sounds simple, but it can affect the whole packaging project. When customers ask me which size they should choose, I normally ask what product they are filling, how often the customer is expected to use it and how the package will be sold.

15ml AS Airless Bottle

The 15ml size is the most compact option in this range. It can be considered for concentrated Skincare Products, serums, eye-care products or other products where a smaller package is preferred.

A smaller package can also make sense when the brand wants to keep the overall package compact. But the final filling volume should always be checked against the actual formula and package specification.

30ml AS Airless Bottle

The 30ml option gives the brand more capacity while keeping the package relatively compact. This makes it a useful choice for many facial skincare products.

For brands developing a serum or facial cream, 30ml is a capacity worth considering when the expected usage does not require a larger bottle.

50ml AS Airless Bottle

The 50ml version provides more product volume and can be considered for facial creams, lotions and other skincare products designed for regular use.

It can also be useful when a brand wants a slightly larger package without moving into a much bigger bottle format.

Building a Product Family

One advantage of having 15ml, 30ml and 50ml options is the possibility of creating a product family. For example, a brand could use a smaller capacity for a concentrated product and a larger capacity for a daily-use cream.

The actual dimensions and visual proportions of each version need to be confirmed, but keeping a consistent packaging concept can help a product line look more organized.

4. Main Features of the Double-layer AS Plastic Airless Bottle

AS Plastic Appearance

AS plastic is often selected when a brand wants a clear and clean plastic appearance. For cosmetic packaging, visual presentation matters because customers usually see the package before they see the product itself.

The clear appearance can work with simple, modern and clean packaging concepts. Depending on the final structure and decoration process, the bottle can also be customized to fit a particular brand identity.

Double-layer Bottle Body

The double-layer structure is one of the main visual features of this package. Instead of presenting a simple single-wall bottle body, the package uses a layered construction that gives it a different visual character.

I find this useful when a brand wants packaging that looks more distinctive without changing the basic airless dispensing concept.

However, I would not describe a double-layer structure as automatically making the bottle stronger or providing a guaranteed barrier against every environmental condition. Those claims depend on the actual structure and testing data.

Airless Pump Design

The airless pump provides controlled product dispensing. It is suitable for brands that want a pump-based package for skincare and personal care products.

We check pump function before shipment because a bottle that looks good but does not dispense properly is obviously not a successful packaging product.

Lightweight Packaging Format

AS plastic provides a lightweight plastic packaging option. For international shipping, package weight can also affect logistics planning, especially when the order quantity becomes large.

Still, actual package weight depends on the final bottle design, components and decoration, so I recommend confirming the approved product specification before calculating the final shipping volume or freight cost.

Multiple Capacity Options

The 15ml, 30ml and 50ml options allow customers to choose a package size based on product positioning. This is particularly useful for brands that want several product sizes under a related packaging concept.

Customization Options

We provide color matching, silk-screen printing, hot stamping, frosting, electroplating and other surface finishes. Depending on the customer's project, we can also discuss new mold development and matching pump heads.

5. Applications of the AS Airless Cosmetic Bottle

The AS Plastic Airless Bottle is designed for cosmetic and personal care packaging. Because formulas behave differently, I prefer to describe the applications as suitable directions rather than making a blanket claim that every cosmetic product can use the same package.

Skincare Serum

Serums are one of the natural applications for a compact airless bottle. The 15ml and 30ml sizes can be considered when the brand wants a smaller skincare package.

Before production, the serum should be tested with the actual pump to confirm dispensing performance.

Face Cream

Face creams can also be considered for the 30ml and 50ml versions. The actual cream viscosity matters because thick products can behave differently from light lotions.

Facial Lotion

Lotions can work well with pump-based packaging when the product has suitable flow characteristics. The airless structure gives users a straightforward press-and-dispense method.

Emulsion

Emulsions vary significantly in their formulation and flow behavior. Sample testing is therefore useful before the final package is confirmed.

Personal Care Products

Selected personal care products can also be considered, especially when a compact pump package is preferred. The final application should always be checked against the formula and package compatibility requirements.

OEM and Private Label Packaging

For OEM and private-label brands, the bottle provides a useful starting point because the package can be customized through colors, printing and surface treatments.

If the customer already has a logo, artwork or existing packaging sample, we can use that information when discussing the next step.

6. Manufacturing and Customization at Yuyao Dingyu

One thing I have learned from cosmetic packaging projects is that production problems usually become easier to manage when the requirements are clear from the beginning.

At Yuyao Dingyu, we therefore start by understanding the customer's actual needs instead of immediately treating every order as a standard bottle order.

Requirement Confirmation

We review the required capacity, bottle structure, appearance, pump, decoration, order quantity and delivery schedule. If the customer has a drawing or sample, we can use it as a direct reference.

Sample Evaluation

We can provide samples before mass production. This gives customers an opportunity to check the actual package instead of making a decision from product pictures alone.

I strongly recommend this step for new products. A sample can be checked for appearance, dimensions, pump operation, assembly and compatibility with the actual cosmetic formula.

Color Matching

Although the standard product concept focuses on AS plastic and a clean appearance, customized colors can be discussed according to the customer's design.

Color matching should be confirmed during the sample stage because the final visual result can depend on material, surface treatment and production conditions.

Printing and Surface Finishing

Our available services include silk-screen printing, hot stamping, electroplating, frosting and other surface finishes.

These processes can change the visual character of the package without requiring the brand to redesign the entire bottle structure.

New Mold Development

When an existing package cannot meet the customer's requirements, we can discuss new mold development. This is useful for brands that need a more customized bottle structure or a specific packaging concept.

New mold projects require additional development time, so the mold schedule should be included when planning the overall product launch.

Injection Molding and Production

Our factory is equipped with multiple injection-molding machines. Injection molding allows us to manufacture plastic packaging components according to the approved specifications.

Production quality depends on many details, including material handling, mold condition, molding parameters, component inspection and assembly. This is why quality control needs to run through the whole production process rather than being left to the final inspection only.

Final Inspection

Before delivery, we check appearance, dimensions, pump function and packaging condition. The exact inspection scope can be adjusted according to the order requirements.

For cosmetic packaging, I consider appearance consistency particularly important. Small visual differences can become noticeable when hundreds or thousands of bottles are displayed together.

Production Time

For standard AS Airless Bottles, production usually takes around 15–30 days after sample approval and order confirmation. Custom mold development may require additional time.

Special colors, decoration and other customized processes can also affect the production schedule. The final delivery date should therefore be confirmed after all specifications are approved.

7. Quality Control, Packing and International Delivery

Quality control is not only about checking whether the bottle looks acceptable at the end of production. We need to consider the bottle from the beginning of molding through assembly and final packing.

Appearance Inspection

We check the bottle surface and visible appearance. This is especially important for clear AS plastic and decorated cosmetic packaging because surface marks can be easier to notice.

Dimension Inspection

Relevant dimensions are checked against the agreed product specification. This helps ensure that the finished package is suitable for the intended filling and assembly process.

Pump Function Inspection

The pump is checked for dispensing function. Customers should also test the pump with their actual product because formula viscosity can affect the final dispensing experience.

Packaging Inspection

Before shipment, we check the packing condition. Our standard packing options include protective polybags, inner boxes and strong export cartons.

When required, pallets or wooden cases can also be arranged for additional transportation protection.

International Shipping

We support sea freight, air freight and express delivery. The appropriate option depends on order quantity, destination, urgency and logistics budget.

For larger quantities, sea freight is often considered because of the shipment volume. For urgent samples or smaller shipments, air freight or express delivery may be more practical. The final choice should be based on the actual order.

8. Why Choose Yuyao Dingyu for AS Airless Bottles?

When a customer buys cosmetic packaging, they are not only buying a bottle. They are also buying a production process, communication process and delivery process.

At Yuyao Dingyu Plastic Industry Co., Ltd., we have our own manufacturing factory and have specialized in cosmetic packaging for 17 years. Our focus on cosmetic packaging gives us experience across airless bottles, lotion bottles, perfume bottles, PET bottles and other beauty packaging products.

Our 5,000-square-meter facility includes mold development workshops, injection-molding machines and testing instruments. This allows us to support customers who need more than a standard catalog product.

We provide OEM and ODM services based on customer drawings or samples. If a customer has an existing package that needs to be reproduced or improved, we can discuss the manufacturing requirements with them.

Our customization services include:

• New mold development

• Color matching

• Silk-screen printing

• Hot stamping

• Electroplating

• Frosting

• Other surface finishes

• Matching pump heads

We also understand that international customers often need fast communication. We aim to reply to inquiries within 24 hours and provide tailored solutions within one week.
