The sealing property of dishwasher capsule packaging plays a crucial role in the use of detergent. It directly affects the quality, performance, safety and user experience of the product. The following is a detailed analysis of its role from multiple dimensions:

Prevent the leakage and failure of active ingredients
The dishwasher capsules contain high-concentration active ingredients (such as enzyme preparations, surfactants, etc.), which are sensitive to environmental humidity and oxygen. If the packaging is not sealed properly, the following problems may occur:
Component leakage: Liquid or powder-like active substances seep out, contaminating transportation packaging or equipment, and even corroding metal parts.
Oxidative degradation: Bioactive components such as enzyme preparations are prone to inactivation when exposed to oxygen, significantly reducing the washing effect.
Deliquescence and caking: After coming into contact with water vapor, some components (such as sodium percarbonate) may deliquesce or caking, affecting the performance in use.
By analogy, a poorly sealed capsule is like a medicine with an unsealed cap. When exposed to the air, its efficacy will rapidly decline due to oxidation or deliquescence.
2. Ensure storage stability and shelf life

In commercial or household scenarios, dishwasher capsules need to be stored for a long time, and sealing is crucial for extending the shelf life:
Moisture-proof and mold-proof: High humidity environments may cause the capsule shell to soften, stick together, and even breed mold, affecting the hygiene and safety of the product.
Avoid cross-contamination: Sealed packaging can isolate external odors, dust or insects, preventing contamination of the capsules.
Maintain component activity: By isolating air and moisture, ensure that components such as enzymes and bleach maintain stable activity during storage.
Case reference: A sealed design similar to coffee capsules, which blocks oxygen and moisture through multiple layers of composite films, extends the product’s shelf life to over one year.
3. Enhance the safety of use
Dishwasher capsules usually contain strong alkaline or oxidizing components. Insufficient sealing may cause safety hazards:
Prevent the risk of accidental contact: If the capsule breaks during storage or transportation, children or pets may accidentally ingest the strongly alkaline substance, causing chemical burns.
Avoid corroding equipment: Leaked detergent may corrode the internal pipes or sealing rings of the dishwasher, shortening the equipment’s lifespan.
Reducing environmental pollution: Sealed packaging can prevent active ingredients from leaking into the environment, reducing potential harm to water bodies or soil.
Data reference: According to industry research, well-sealed capsules can reduce the risk of leakage by over 90%, significantly enhancing the safety of use.
4. Optimize user experience and convenience
The sealing design directly affects the user’s satisfaction with the product:
Individual packaging: Each capsule is independently sealed, allowing users to take as needed, avoiding the trouble of frequently opening the lid with traditional detergents.
Moisture-proof and anti-sticking: In a humid environment, the sealed packaging can prevent the capsules from sticking together, facilitating one-handed operation and the use of automatic dispensing equipment.
Precise dosage: Sealed packaging ensures that the content of active ingredients in each capsule is consistent, avoiding insufficient dosage due to moisture or evaporation.
In high-frequency usage scenarios such as restaurants, well-sealed capsules can reduce waste caused by moisture and improve the efficiency of dishwashing at the same time.
5. Adapt to the high-intensity working environment of dishwashers
Dishwasher capsules need to dissolve and release their components rapidly under high temperature, high pressure and strong water flow conditions. The sealing performance should meet the following requirements:
Resistance to mechanical stress: Vibration or compression during transportation may lead to seal failure. To enhance packaging strength, material optimization and structural design are necessary.
Rapid dissolution and release: The sealed packaging should disintegrate quickly at the initial stage of washing to ensure that the active ingredients come into full contact with the tableware.
Compatible washing program: For different washing modes (such as quick wash and energy-saving wash), the capsules need to complete dissolution within a specific time, and the sealing design should be matched accordingly.
Technical key points: Through the composite structure of water-soluble film and outer protective film, the dual functions of “sealing during storage and dissolving during washing” are achieved.
