Vacuum Sealers: What are they and how do they work?

Vacuum sealers are a great way to keep food fresh for longer. They work by removing air from a sealed bag or container, creating an airtight environment that helps preserve the freshness of food. Vacuum sealing works by using a vacuum pump to suck out the air and then sealing the bag with heat. This process creates an oxygen-free environment which prevents bacteria growth and keeps food fresher for longer periods of time.

Vacuum sealers are a great way to keep food fresh and extend its shelf life, but for some tasks heat sealers may be more suitable – so let’s explore the benefits of these next.

Heat Sealers: What are they and how do they work?

Heat sealers are an effective way to store food and other items for long periods of time. They use heat to create a tight bond between two pieces of plastic, forming an airtight seal that prevents air from entering or escaping. The effectiveness of heat sealers for extended food storage is evident; the tight bond formed between two pieces of plastic creates an airtight enclosure, preserving freshness and safety.

Heat sealers work by melting two pieces of plastic together using heat. The application of heat causes the two pieces to coalesce, creating a durable seal that seals off any ingress or egress of air and moisture. Heat sealing can be done manually with a handheld device, or automatically with larger machines designed specifically for this purpose.

Heat sealers provide a simple and efficient way to package food, but they are not the only sealing solution. Vacuum sealing offers an alternative method of preserving food that can be just as effective and has its own unique benefits – let’s take a look at those now.

Benefits of Vacuum Sealing

It works by extracting oxygen from the bag or receptacle, thus disallowing bacteria to propagate and damage your food. Storing food in your cupboard or fridge can be done without fretting over it going bad speedily thanks to vacuum sealing. Vacuum sealing also helps reduce freezer burn and dehydration, so you don’t have to worry about wasting money on spoiled food.

One of the biggest benefits of vacuum sealing is that it extends the shelf life of many foods significantly. For example, when vacuum sealed properly, most meats can last up to three times as long as they would if stored in their original packaging. You can purchase larger amounts of food without having to fret about spoilage, due to the extended shelf life provided by vacuum sealing. Additionally, because there is no air inside the bag or container with vacuum sealed items, mould growth is greatly reduced compared to traditional storage methods like plastic wrap or aluminium foil.

Another benefit of using a vacuum sealer is that it takes up less space than other types of storage containers such as Tupperware or Ziploc bags. Since all the air has been extracted, these containers are significantly more diminutive than their non-vacuumed equivalents – making them ideal for containing tiny amounts of leftovers in cramped spaces like dorms or desktops where space is limited. Additionally, since there’s no air inside these containers they won’t take up any extra room in your fridge either.

Vacuum sealing also offers the benefit of protecting delicate items such as spices and herbs from oxidation, thus allowing them to stay fresher for longer than if stored traditionally in jars or bags with lids. This makes vacuum sealed containers ideal for preserving things like freshly ground coffee beans, which require an airtight environment to retain their flavour over time.

Vacuum sealing is a great way to preserve food, but heat sealing also has its own unique advantages that are worth exploring. Let’s delve into the advantages of heat sealing in what follows.

Key Takeaway: Vacuum sealing is a great way to preserve food and keep it fresh for longer, saving time and money while ensuring maximum convenience when storing groceries.

Benefits of Heat Sealing

Heat sealing is a marvellous technique for preserving edibles for extended periods of time, forming an air-tight barrier that precludes the infiltration or exudation of oxygen, thus thwarting microbial growth and sustaining the freshness of your nourishment. It creates a tight closure that blocks oxygen from infiltrating or leaking out of the bag or receptacle, thus limiting microbial activity and preserving your food’s freshness for an extended period. This means you don’t have to worry about freezer burn or dehydration ruining your favourite foods.

One of the biggest benefits of heat sealing is that it’s incredibly easy to do. All you need is a heat sealer and some bags or containers with special linings designed for heat sealing. Simply insert the item to be sealed into its designated bag, then run a heat sealer along the top edge of said pouch until it is securely fastened. You can also utilize this technique for sealing up jars, cans, bottles and other types of receptacles.

Another benefit of using a heat sealer is that it helps preserve flavour better than traditional methods like freezing or refrigeration because there’s no risk of freezer burn or oxidation due to exposure to air. Heat-sealed food will retain its original taste and texture much better than if stored in another way – making it perfect for storing items like spices, herbs, coffee beans, nuts and seeds etcetera without losing any flavor over time.

Heat sealing also makes portion control easier since you can easily create individual portions within one large package by simply running multiple seals across each item separately before placing them into storage bags/containers – meaning less waste overall. And since these packages are already pre-portioned out they’re much more convenient when packing lunches too.

Finally, heat sealing offers added protection against moisture damage which can ruin certain products such as electronics components and pharmaceuticals; so if you’re looking for an extra layer of security when transporting sensitive items then this could be just what you need.

Overall, there are many advantages associated with using a heat sealer; from preserving flavours better than traditional methods to protecting delicate items during transport. Therefore, it is worth investigating the potential benefits of heat sealing.

Key Takeaway: Heat sealing offers a convenient, efficient way to keep food fresh for longer and protect delicate items from moisture damage. It’s an easy-to-use solution that provides superior flavour preservation compared to other methods.

Which One Should You Choose?

Vacuum sealing and heat sealing are two popular methods of food storage. It’s essential to comprehend the distinctions between vacuum sealing and heat sealing prior to opting for which one is best suited for your needs; both have their own respective benefits.

When deciding between vacuum sealing and heat sealing, it is important to consider the desired outcome of your food storage needs. If your aim is to store food for a lengthier period, then vacuum sealing might be the more suitable choice; however, if you need something in a hurry, heat sealing may be preferable. Vacuum-sealed edibles can remain consumable for up to five times longer than those not sealed with a vacuum and require less space when stored due to the lack of bulky containers or wrapping materials that are usually needed. Heat seals don’t last as long as vacuum seals – typically only about three months compared with six months for a properly made vacuum sealer bag – so if you plan on storing something over an extended period of time, it might be best suited for a vacuum sealer instead of a heat sealer.

Key Takeaway: Vacuum sealing offers longer-term storage solutions, while heat sealing is more immediate; vacuum sealed food can last up to five times longer than non-vacuum sealed food stored in the refrigerator or freezer.


When it comes to choosing between vacuum sealer vs heat sealer, it really depends on what you’re looking for. Vacuum sealers are great for preserving food and keeping items airtight, while heat sealers offer more versatility in terms of the materials they can work with. In the end, both types of sealers provide their own advantages that should be considered when deciding which one is suitable for your needs. So whether you choose a vacuum or heat sealer, just remember that either way you’ll be making sure your items stay safe and secure.
