Mylar bags offer a convenient and effective way of storing food, medicine, and other important items for long periods of time. But to ensure maximum protection from air, moisture, and other contaminants, you need to seal them properly.
If you’re looking to seal your custom mylar bags professionally, then this guide is for you. In the following paragraphs, we’ll cover the different ways to seal mylar bags and provide tips to help you achieve the best results. With this knowledge, you can be confident that your valuable items will stay fresh and protected for as long as possible.
Before we dive into the different methods of sealing mylar bags, it’s important to note that not all mylar bags are the same. Some are equipped with ziplock closures, while others require heat sealing. Depending on the type of mylar bag you’re using, you’ll need to choose an appropriate sealing method.
Method 1: Heat Sealing
1. Place the items you want to store in the mylar bag and remove any excess air.
2. Place the open end of the bag between the heat sealer’s jaws.
3. Press down on the heat sealer for a few seconds, allowing the heat to melt the mylar layers together.
4. Release the pressure and wait for a few seconds for the seal to cool and solidify.
Method 2: Iron Sealing
If you don’t have a heat sealer machine, you can use an iron to seal your mylar bags. This method isn’t as effective as heat sealing, but it still provides adequate protection for short-term storage. Here’s how to iron seal a mylar bag:
1. Place the item you want to store inside the mylar bag.
2. Roll the open end of the bag over twice and hold it tightly.
3. Place a sheet of parchment paper over the rolled end of the bag.
4. Use a hot iron on low to medium heat to press down on the parchment paper for 5-7 seconds.
5. Remove the iron and parchment paper and let the seal cool for a few seconds.
Method 3: Tape Sealing
If you’re in a pinch and don’t have a heat sealer or iron, you can use tape to seal your mylar bags. This method isn’t ideal for long-term storage, but it can work in a pinch. Here’s how to tape seal a mylar bag:
1. Place the item you want to store inside the mylar bag.
2. Roll the open end of the bag over twice and hold it tightly.
3. Cut a strip of packing or duct tape long enough to cover the rolled end of the bag.
4. Place the tape over the rolled end of the bag, covering it completely.
5. Press down firmly on the tape to ensure a secure seal.
Method 4: Ziplock Closure
If your mylar bags have ziplock closures, you don’t need to worry about sealing them at all. Simply place your items inside the bag and close the ziplock tightly to create an airtight seal. It’s important to note that ziplock closures aren’t suitable for long-term storage, but they’re great for short-term use.
Conclusion:
Sealing your mylar bags professionally is critical if you want to ensure your stored items remain fresh and protected for as long as possible. By following the methods outlined in this guide, you’ll be able to seal your mylar bags effectively and securely, no matter the circumstances.
