Induction sealing is a non-contact means of heating a metallic disk to hermetically seal the top of plastic and glass containers. Various industries, such as food and beverage, pharmaceuticals, cosmetics, and chemicals, rely heavily on induction sealing for their packaging and distribution operations. From sealing dairy products and nutraceuticals, to chemicals and automotive petroleum products, induction sealing is crucial for building trust with, and successfully delivering high-quality products to your customers.
But the question still remains: Why induction sealing? Why is having a high-quality seal on your products so important? Pillar's team of Application Engineers and Sales Specialists put together a list of the top four reasons for induction sealing:
-
Tamper Evidence - Tamper evidence is a way to make unauthorized access to a product or object easily detectable - such as packaging that tears open raggedly and cannot be resealed. The FDA has instituted regulations concerning tamper-resistant packaging - forcing packagers to find new ways to comply with the strict FDA regulations, which can be found
here. Because Pillar's induction sealing systems meet and exceed FDA regulations, you won't have to worry about tampering at all with your products.
-
Leak Prevention - A chemical manufacturer was told that they had to find a way to prevent their products from leaking during shipment or else the freight carrier would not be able to accommodate their shipping needs. As a result, the chemical company found that the only way to secure their liquid chemical products was by using an induction seal on their plastic bottles. With an induction-sealed product, the only way for a leak to occur is if the product wasn't properly sealed at the correct output setting, or if the seal was incorrectly placed inside the cap - both causing an improper weld that could lead to an increase in leaks. This mean that with the right, high-quality induction seal, you have the ability to avoid leaks from occurring
-
Freshness (Extended Shelf-Life) - During production, unwanted pollutants and contaminants can seep into food products if not hermetically sealed. Because of this, induction sealing is the only method to preserve freshness and ensure that these particles and contaminants do not enter the bottle. Although Pillar does not claim to provide extended shelf-life to induction sealing food products, our customers do make this claim. Major food processors and packagers have told Pillar that their products, once induction sealed, are fresher and last longer.
-
Pilferage Protection - Induction sealed containers help prevent products from being broken into, or tampered with, by leaving a noticeable residue on the bottle from the liner itself. In addition to this, it also stops customers from sampling products without purchasing. While many pharmaceutical companies purchase these liners to allow for easy detection of products that have been tampered with, food companies typically don't want the liner residue as it could interfere with the product itself. They, in turn, put a notice on the product that it has been induction sealed for their protection - letting the customer know that there was a liner on the plastic bottle prior to purchase.
Importance of Induction Sealing
Because of the large amount of risk involved with producing, packaging, and distributing goods to consumers, it's critical that all necessary precautions are taken to prevent against tampering, leaks, pilfering, and contamination. Induction sealing is the ideal solution for ensuring all of your products are packaged and processed correctly in order to maintain trust and reliability with customers. Without it, your facility is at risk of a large increase in product quality rejects, legal implications due to damaged/contaminated products, and much more - costing your business time and money in the long run.
How Pillar Technologies Can Help
Pillar Technologies launched the first solid-state induction cap sealer in 1973 and have since made critical and nuanced tweaks to their sealing machines as technology has progressed. Pillar is a leader in induction sealing solutions, with less parts, our systems are less than 1/2 the size of the formerly-popular water-cooled system - meaning less opportunity for part failure, and virtually no maintenance. In addition to this, Pillar offers the widest range of power supplies available in a waterless system - from 1000 watts (1kW) up to a full 6000 watts (6kW) - to ensure a high-quality seal on all of your products.
