When it comes to sealing bottle caps, plastic caps are commonly used. These are easy to fit over metal caps, making them more secure and airtight. However, not all plastic caps are created equal; some can be quite tricky to seal properly. That's where a heat gun comes in handy. With a little bit of practice, you can use a heat gun to seal plastic caps on bottles with ease. In this blog, we'll take a closer look at 3 ways to use a heat gun for sealing caps.
1. Preheat the Cap
Before you even start sealing the cap, you need to preheat it. This will make the plastic more pliable, making it easier to seal once you apply heat. To preheat the cap, hold it over the heat gun for a few seconds. Move the heat gun around so that the heat is evenly distributed over the entire cap. When the cap starts to feel warm to the touch, it's ready to be sealed.
2. Seal the Cap Vertically
Now it's time to seal the cap. Hold the cap vertically over the heat gun, with the opening facing down. Move the heat gun around so that the heat is evenly distributed over the entire cap. Keep the cap moving to prevent melting the plastic. Once the plastic starts to buckle and shrink a little bit, remove the heat gun and press the cap down onto the bottle opening. Hold it in place for a few seconds until the plastic cools and hardens.
3. Seal the Cap Horizontally
If you prefer, you can also seal the cap horizontally. This method is particularly useful if you want to ensure that the entire rim of the cap is sealed. To do this, hold the cap horizontally over the heat gun, with the opening facing up. Move the heat gun around so that the heat is evenly distributed over the entire rim of the cap. Again, keep the cap moving to prevent melting the plastic. Once the plastic starts to buckle and shrink a little bit, remove the heat gun and press the cap down onto the bottle opening. Hold it in place for a few seconds until the plastic cools and hardens.
In conclusion, with a heat gun and a little bit of practice, you can easily seal plastic caps on bottles. Remember to preheat the cap, and then use either the vertical or horizontal method to seal it. Whether you're a homebrewer or just looking to keep your drinks fresh and secure, using a heat gun is a great way to get the perfect seal.
