Today, coffee is much more than a drink. People are always in pursuit of the best coffee in any of its forms. That’s why the packaging of your coffee beans or ground coffee matters.
Oxygen is one of coffee’s worst enemies.
Contact with it can cause degradation of quality, so your packaging must have a
good seal. This is where a constant heat sealer comes in.
Keep on reading to learn what it is, how it
helps, and how to choose the best one for you.
What are Heat Sealers
Heat sealers, as the name suggests, use heat
to seal any type of packaging and thermoplastic materials. It uses pressure to
put together the materials and then heat to seal them.
There are many ways to do this, which is why
we have different types of heat sealers. A constant heat sealer is only one of
them. You may also refer to it as a hot bar or direct heat sealer.
This type of heat sealer uses one heat bar or
two, which are both set at a high temperature. You lower the jaw to apply
pressure, and the heated bars do the rest of the job.
It’s called a constant heat sealer machine because the heat is continuous. This separates it from, say, an impulse heat sealer.
The direct heat sealer uses power as long as
it’s turned on it has to maintain a high temperature. You also have to take
great care when using one due to the constant heat.
The advantage of this set-up is that it has
greater heat penetration. This makes it a great choice if you want to use a
coffee bag with a thicker material. It’s great for coated aluminum foils,
coated Kraft paper, poly cello films, mylar, and more.
Why Do You Need One?
Heat sealers can create an airtight seal
that’s hard to break. For coffee bags, this is important because you need the
contents to be fresh for a long time. The airtight seal prevents it from
getting in contact with outside air, thus preventing spoilage and oxidation for
a long time.
They’re also pretty easy and straightforward
to operate. All you have to do is place the bag in the sealer, lower the jaw,
and that’s it.
It makes the whole process of packaging coffee
easier. It streamlines the process because the constant heat means you don’t
ever have to worry about warming it up first before usage.
How to Choose a Constant Heat Sealer
A constant heat sealer further has different
types and models. How do you choose the best one for your needs?
1. Assess Your Needs
To learn the best type of constant heat bag
sealer for you, first, find out what your needs are.
For a start, how much workload are you
anticipating? If you’re packaging hundreds of coffee bags at a time, you’ll
have to make sure the machine can handle it. You may want to use at least a
foot sealer, to make it faster and easier.
The width of your coffee bags matter, too. The
size of the heat sealer you’ll get depends on the sizes of your coffee bags.
The safest choice would be a wider constant
heat sealer than what you need. With it, you can also seal smaller coffee bags.
Get an inch wider than your biggest coffee bag for easier handling. You’ll also be able to still use it should
you decide to use a bigger bag size.
A heat sealer is an investment, so you have to
think about the future, too. This can be hard to do, however, when you consider
your budget.
2. Think of Your Budget
Your budget is likely the main driving factor
in your decision-making. Aside from your needs, you must choose a machine that
fits your budget.
There’s nothing wrong with buying what you can
afford now, then buying a bigger and better one when you go big.
If budget permits, though, buy one that
slightly goes beyond your needs. This will ensure you get to use it even if
your production demand increases.
3. Consider Your Coffee Bags
What type of coffee bags are you using? We have
Kraft, foil, and clear poly materials. All of which we’ve designed to keep
moisture and air out.
Aluminum foil is the best for maintaining
freshness, though.
The type of coffee bag you’ll choose will
determine the right heat sealer for you. Pay attention to the mil; it’s the
measure of the material thickness.
Materials that are 1 - 3 mils thick are light
to standard. Those with 4 - 8 thickness are medium to heavy. The latter
require thicker seals for proper mending.
4. Check Out the Different Types
Constant heat sealers have subcategories.
There are portable sealers, pedestal types, hand sealers, and so on.
The best choice of bag sealer for you would
depend on your needs.
Portable sealers are for you if you’re always
moving about with your coffee bags. They’re small yet still powerful. They can
still handle thick materials, although not the thickest ones.
They’re the cheapest option, as well. If you
have a tight budget, this is still pretty capable for the job. They’re pretty
versatile but you’re limited in sizes.
Foot sealers are a solid choice for
high-volume sealing. This type of heat sealer uses some sort of a pedal to
activate.
You use your foot to activate it, keeping both
your hands-free. This allows for faster and more accurate sealing.
They’re also bigger, so you can seal materials
up to 24 inches wide and 15 mils thick.
Bench heat sealers can be automatic, which
means you can set the jaw to lower down at certain time intervals. They usually
come with a footswitch, though, for manual operation. The AIE CA series would
be a great option for this type of machine.
