Practical and Safe Expressed Breast Milk Bottle | Hegen PPSU Express-Store-Feed System
For many mothers who return to work, pumping often becomes a challenging part of the daily routine. Between office responsibilities and household needs, they still need to ensure their breast milk supply remains sufficient. After pumping, breast milk is usually transferred from the pump bottle to a storage container, then into an expressed breast milk bottle for feeding the baby.
Although it may seem simple, these steps consume time and energy. Each transfer carries its own risks, ranging from spilled milk and potential contamination to concerns about reduced nutritional quality.
Many mothers do not realize that the issue is not only about perceived low milk production, but also about using an expressed breast milk bottle that is not practical and requires multiple container transfers. The more steps involved, the greater the risk of milk loss and declining quality.
To understand why this happens and how a more efficient solution can help, let us move on to the main discussion below.
Why Does Transferring Milk Between Containers Increase the Risk of Contamination?
Based on easy-to-understand scientific principles, every transfer of breast milk from one container to another increases bacterial exposure. When milk is poured, outside air comes into contact with the liquid surface. Contamination can occur from hands, container funnels, or the surrounding environment. This is especially risky if the container used is not a hygienically designed expressed breast milk bottle.
Breast milk is a liquid that is extremely rich in nutrients, but it is also highly sensitive to temperature and oxidation. When left too long in open air or exposed to fluctuating temperatures, important components such as enzymes, antibodies, and immunological substances can decline in quality.
Each time breast milk is transferred, the potential increases for bacterial exposure from air or hands, nutrient degradation due to oxidation, temperature changes that damage sensitive components of breast milk, and the risk of spilling and waste.
An important fact to understand is that babies are highly vulnerable to digestive infections. Therefore, the cleanliness of breast milk storage containers is not merely a preference, but a priority. This is where choosing a safe and anti-contamination expressed breast milk bottle becomes critically important.

Breast Milk Safety Standards: Requirements for a Safe and Healthy Expressed Breast Milk Bottle

Breast milk safety standards should never be overlooked, especially when choosing an expressed breast milk bottle used daily. Not all plastic containers or storage bottles are designed to preserve breast milk quality.
Because breast milk is highly sensitive to temperature, air exposure, and container hygiene, bottle selection must meet specific standards to ensure nutrients remain optimal from expression until feeding. Here are the key requirements to consider.
1. Food Grade and Toxin-Free Material
Choose an expressed breast milk bottle made from food grade material that is free from BPA, BPS, and phthalates. These substances are harmful because they can leach out when exposed to heat or with repeated use. Safe materials help ensure breast milk is not contaminated by chemicals.
2. High Heat Resistance for Sterilization
Sterilization requires high temperatures. The bottle must withstand temperatures of 100°C or more without melting, deforming, cracking, or releasing odors. This is essential to keep the bottle hygienic with every use.
3. Does Not Yellow Easily or Absorb Odors
If a bottle easily changes color or absorbs smells, this may indicate unstable material. Such bottles have the potential to release small particles that can contaminate breast milk.
4. Airtight and Leak-Proof
An airtight bottle keeps breast milk fresh and prevents oxidation. A leak-proof design also minimizes the risk of spills during storage, transport, or warming.
5. Minimal Gaps in Design
Too many threads or joints can become breeding grounds for bacteria. A good expressed breast milk bottle should be easy to clean and have a simple structure.
6. Practical and Efficient
Ideally, the bottle allows expressing, storing, warming, and feeding without needing to transfer milk into multiple containers.
All of these standards can be found in premium systems like Hegen, which is specifically designed as a complete and efficient expressed breast milk bottle solution for modern mothers.

Hegen Premium Solution: Express-Store-Feed System Without Container Transfers

Hegen offers a system that simplifies the pumping routine for mothers. With its all-in-one concept, Hegen eliminates the most risky step in breast milk storage, which is transferring milk between containers. Here are the main advantages that make Hegen a top choice.
1. Modular All-in-One System
Hegen is designed to support a more practical breastfeeding process. This system allows mothers to pump breast milk directly into the bottle, store it without transferring containers, warm the milk in the same bottle, and feed the baby without pouring it into another bottle.
This approach eliminates the need for repeated milk transfers, significantly reducing the risk of spills, nutrient loss, and contamination. Because of its convenience and efficiency, Hegen is often recommended as the most suitable expressed breast milk bottle for mothers with high mobility.
2. Medical Grade PPSU Material
PPSU material is known as one of the safest medical plastics. Its advantages include heat resistance up to 180°C, safe freezer use down to -20°C, resistance to yellowing, no odor absorption, and free from BPA, BPS, and other toxins.
The stability of this material ensures that no microplastic particles are released when the bottle is heated. Because of these characteristics, Hegen is a reliable choice for maintaining optimal nutrition in an expressed breast milk bottle.
3. PCTO™ Airtight Lid (Press-to-Close, Twist-to-Open)
The threadless PCTO™ lid technology makes breast milk storage more hygienic. The absence of threads reduces areas where bacteria can accumulate, making cleaning easier. In addition, the bottle becomes leak-proof, airtight, can be opened with one hand, and enhances daily safety when using an expressed breast milk bottle.
4. Safe for Warmers or Gradual Heating
Hegen can be used for warming, whether placed in warm water or heated gradually, without the risk of deformation or leakage.
5. Purpose-Built Accessories
The Hegen system includes accessories such as a breast pump adapter, storage lid, feeding lid and teat, sealing disk, and anti-colic teat. All accessories are integrated, making the expressed breast milk bottle even more practical for modern mothers.
