10 Innovative Packaging Sealing Technologies for Your Product
How Does Induction Sealing Process Work?
The induction sealing process uses electromagnetic induction to create a secure and hermetic bond between a foil laminate and the container’s lip. Below, we detail the complete process, step by step:
Step 1: Setting Parameters
- The induction sealing machine’s power, conveyor speed, and sealing time are configured according to the specific requirements of the product and materials being sealed. Proper parameter settings are critical to achieving a consistent and high-quality seal.
Step 2: Ensuring Compatibility of Materials
- Verify that the induction liners being used are compatible with the container and closure material. This step ensures effective bonding and prevents sealing failures.
Step 3: Preparing the Closure
- Insert the induction seal liner into the container’s closure. Securely place the closure onto the container, ensuring that the liner is properly positioned for sealing.
Step 4: Loading Containers onto the Conveyor
- Carefully load containers onto the conveyor system of the induction sealing machine. Make sure the containers are center-aligned with the marking labels on the sealing area to avoid misalignment during the process.
Step 5: Guiding Containers Through the Sealing Area
- Activate the conveyor system to transport containers smoothly underneath the induction coil. The coil generates the electromagnetic field necessary for the sealing process.
Step 6: Heating the Induction Liners
- As containers pass through the electromagnetic field, the induction liner heats up. This heating activates the bonding materials in the liner.
Step 7: Creating the Seal
- For two-piece liners: The heated foil melts the wax layer, which is absorbed by the backing material (foam or pulpboard). Simultaneously, the heat-seal polymer bonds to the container’s lip. The liner then separates into two parts: the seal and the backing.
- For single-piece liners: The heated foil melts the heat-seal polymer directly, bonding it to the container lip. This creates a tamper-evident, airtight, and leak-proof seal.
Key Benefits of Sam Lan Induction Sealing Solutions
1. Tamper Evidence
Induction sealing provides a visible guarantee of product safety. The foil seal acts like a protective layer that ensures no tampering has occurred. When intact, it tells your customers that their product is secure and untouched, building trust and peace of mind.
2. Freshness Preservation
An airtight seal created by induction sealing locks in freshness and flavor. By keeping out moisture and oxygen, it ensures that products like snacks, baked goods, and pharmaceuticals remain as effective and delicious as the day they were packaged.
3. Leak Prevention
Induction sealing creates a tight, spill-proof seal for containers. This feature is particularly valuable for liquid or viscous products like sauces, syrups, and detergents, ensuring safe transport and storage without messy spills.
4. Versatility
One of the standout features of induction sealing is its adaptability to a wide range of materials. From plastic to glass to metal containers, induction sealing delivers consistent performance across all types, making it a versatile choice for businesses.
5. Adaptability to Product Varieties
No matter the size, shape, or closure type of your container, induction sealing can handle it all. Its flexibility ensures a perfect seal for everything from small pharmaceutical vials to large beverage containers.
6. Reduced Product Evaporation
For liquids prone to evaporation, such as perfumes or chemicals, induction sealing prevents product loss by locking in the contents. This ensures consistent quality and volume over time, maintaining the product’s intended concentration.
7. Environmentally Friendly
Induction sealing minimizes the need for additional adhesives or materials, making it an eco-friendly packaging solution. By reducing waste and energy consumption, it contributes to sustainable practices in the packaging industry.
8. Efficiency and Speed
Designed for high-speed production lines, induction sealing enhances packaging efficiency. It allows businesses to seal thousands of products quickly, meeting the demands of mass production with ease.
9. Cost-Effective
While the initial setup cost for induction sealing equipment might seem significant, the long-term benefits far outweigh it. By improving efficiency, reducing product waste, and extending shelf life, it becomes a cost-effective solution that saves money over time.
