Induction sealing bonds thermoplastic materials by induction heating. It is a useful method to help with leak prevention, freshness prevention, sustainability, production speed, and it is an effective protection against package pilferage. Below you will find information about how induction sealing works and its respective benefits.
How Induction Sealing Works
Induction sealing bonds thermoplastic materials by induction heating. Thermoplastic materials include plastic polymers that become pliable or moldable at higher temperatures. However, thermoplastics also solidify at cooler temperatures.
Induction sealing produces a hermetic seal through a non-contact process by passing a capped bottle under the induction sealer. The induction sealing process sealing head produces an electromagnetic field that heats up the foil liner found inside the cap. The foil is hot and melts the polymer coating in the inner seal. The pressure of the cap and heat cause the inner seal to bond to the lip of the container. This results in a hermetic seal which is airtight and strong.
Uses for Induction Sealing
Induction sealing is used in the manufacturing process in a number of different industries. Everything from the food and beverage industry, to automotive and sporting goods supplies. It is often used for package fabrication, including forming flexible materials, tubes, and attaching plastic closures to package forms.
The most common use is cap sealing, a non-contact sealing method. The method involves heating the inner seal which hermetically seals the top of plastic and glass containers. The seal process occurs after the bottle has been filled up and capped. Specialty seals are effective in a variety of applications and offer a number of benefits as compared to alternatives, such as conduction sealing.
Features of Induction Sealing
Induction sealing is a useful method that has a number of different applications. Below are some of the main features of induction sealing.
Leak Prevention: Liquids are often shipped long distances and cannot leak. Businesses and shipping companies utilize induction sealing to ensure that liquid products are sealed in order to avoid spillage and preserve the amount of product.
Freshness Preservation: Induction sealing not only helps prevent leakage, but it is also a great method for preservation. It can keep unwanted pollutants out and increase the shelf life of certain products.
Pilferage Protection: One of the major benefits in terms of safety when it comes to induction sealing is the pilferage protection. The method can help prevent products from being broken into as it leaves a noticeable residue from the liner itself on plastic containers.
Sustainable: In certain applications, induction sealing is a sustainable option. It can lower bottle weights resulting in less waste. Some businesses have environmental goals and the sustainability of induction sealing can assist in achieving those goals.
Benefits of Induction Sealing
There are a variety of sealing methods. Two common sealing methods include induction and conduction sealing. Induction sealing comes with the following benefits as compared to alternative methods.
- Fast Production Time: Induction sealing is much faster as they require very little power resources and start up instantly.
- Adjustable: The sealant head can conform to containers that are out of the basic specifications. The adjustability helps when working with various applications.
- Basic System: Alternative sealing systems can be complex with various requirements. Because induction sealing doesn’t have complex sensors or heaters, the system reduces the complexity of the process. Despite the basic system, induction sealing is still highly applicable in a variety of industries as what it produces is not compromised.
