The prerequisite for packaging is a tamper-free guarantee. The packaging is done to ensure that the product inside is transported without tampering or damaging the package’s contents. Hence, those involved in packing and transportation must achieve tamper-proof packaging.
Pharmaceutical products require a certain standard of packaging. There is a stringent checklist that they need to adhere to. The problem arises manufacturers are required to sell their products that don’t tamper or damage the quality of their manufactured product. Simultaneously, they need to choose cost-effective materials and technology for packing; otherwise, the company’s performance in the consumer market might be affected.
In short, the companies are trying to find the most effective technology for packaging that will not affect the quality of the product and at the same time one that doesn’t greatly affect the price margin of the product.
After certain legislative measures were passed, companies began to take the matter seriously. They started looking into various methods and techniques to pack their products without tampering with them. Some of them began to opt for bubble wraps and shrink wraps to protect the contents of the box; some began to use sealed caps to prevent any leakage or tampering.
These methods still don’t prove to be efficient. The wrappers and bands are not foolproof, and the sealed bottles and containers cause inconvenience to the customers. Great physical strength is required to open these packages sometimes. Those with compromised physical strength or the aged find it difficult to open the products. Hence, there is an ongoing search for coming up with a technology that allows these companies to pack without tampering with their products and one that also doesn’t cause inconvenience to the customers.
Induction Sealing Technology
What is induction sealing technology? Induction sealing is a technology where there is a zero-physical contact packaging that is done by using heat induction sealer , the container is sealed with a heatable foil-like material. It is tamper-proof and is also cost-effective. For customers, this sort of sealing is a great relief, as they can easily peel off the layer of failure. They don’t have to exert all their energy into the opening or biting into a tightly sealed cap.
What is the process of Induction sealing technology?
The entire process starts within a closed structure that is made of layers of pulpboard, wax, aluminum foil, and polymer. The induction begins inside this structure. A container is first placed inside this box-like structure, and an electromagnetic current is produced. This current is induced into the foil. The foil heats up due to the heat produced; the wax layer melts because of the excessive heat generated. The pulpboard then absorbs this wax. Once this happens, the polymer melts, and the foil is released. This foil is sealed onto the mouth of the container. The entire process happens very quickly. Large amounts of containers can be sealed within minutes. The time consumed in this method is extremely less. This sort of technology can be adapted by both small and large capacity production companies.
The material used in the foil decides the “tamper evidence” criteria. If you use a material that follows the FDA standards of regulation, the product will not be easily tampered with. This sort of sealing is cost-effective and also adds a great convenience factor.
Advantages of Induction sealing technology
- Tamper evident sealing- The primary criteria for packaging was to ensure that it is tamper-proof. This sort of induction sealing protects the contents of the container and prevents any sort of damage. In this technology, the product is sealed inside and cannot be tampered with unless you physically peel the foil skin off.
- Leak-proof- Induction sealing ensures that the container doesn’t leak or spill the contents. Everything is packed safely within the foil layer. It protects the product from any leakage.
- Cost-effective- The entire process is cost-effective. It doesn’t cost much for the manufacturer, and hence the consumer can buy the product at affordable rates. The packaging doesn’t impact the cost of the product greatly.
- Time-saving- Induction sealing is completed within seconds. It doesn’t consume a lot of time. Large quantities are sealed quickly. It does not have any tedious procedures involved.
Effectiveness of the technology
It all depends on the material of the liner used. The product used here impacts the quality of packaging greatly. The seal will remain tamper and leak-proof only under certain factors. First, the pressure used in the machine must be the right amount. If it is lesser than the standard measure then, the seal might not stick for long. The electromagnetic field must generate the right amount of heat. The entire game is based on the heat and pressure produced. If this part of the machine or structure is faulty, then the process will be in vain. Also, those involved must ensure that the measurements and proportions of the container’s opening and the width of the seal are proportionate. Miscalculations also lead to great inconveniences and affect the quality of the packing. The container must be leveled; there should be uniformity in the containers. The interplay of all these factors affects the functioning of the seal.
Induction-based sealing is what is popularly used today. This technology has proven to be user-friendly for multiple reasons. It crosses the entire checklist of an effective packaging system. Tamper-proof packaging is what induction sealing delivers. There is no room for any damage or leakage of any sort. The products are secure within the sealing. The pressure and heat with which the seal is applied ensure that it does not come off easily with a push. Physical force is required to peel the layer off. Hence, the products in the container will not fall off while transporting or moving. Even from the user’s perspective, this packaging is highly efficient. It is easy to remove while using, and doesn’t require great physical strength. At the same time, this packaging follows all the standard requirements. Induction sealing is one of the best technologies in the packaging industry.
