Buying Tips For Impulse Sealers

Rushing to buy might not be the way to go as you are likely to make a wrong decision. You ought to focus on the following things during the search:

Need at Hand

If you handle small items, then you don’t have to spend lots of money on a heavy-duty unit. However, if you run a very busy business that seals packages all the time, you need a commercial unit to handle the huge volume. A weak or small unit will be overwhelmed and will break down sooner.

Energy Efficiency

Sealers are powered by electricity. The rising cost of energy has forced people to look for energy-efficient units. A good one will consume minimal energy but still, provide excellent service and also handle thick poly or plastic bags. The unit will have a power rating (watts) to show the consumption. Impulse sealers will automatically turn on when pressed and switch off when the handle is released. This helps to lower energy consumption.


The sealers have different weights. Operating a very heavy unit is counterproductive since it isn’t easy to move around with. The user will more likely go to where the unit is rather than carry it to his/her workstation. A lighter one is more practical. Nevertheless, it should have a firm base for the best stability.


You should pay attention to your safety and that of others. If it’s too heavy and bulky, it will injure you in case it falls on you compared to a lighter or smaller unit. The heating element should be well-positioned to prevent accidentally touching it. Also recommended is ensuring the handle is easy to operate and has a good surface. It’s advised to pick a unit with indicator lights that show when it’s on or off.

Proper Use of an Impulse Sealer (Step by step)

If you don’t follow the correct procedure, the sealing will not be satisfactory. It may leave gaps in-between, may burn too much material, or will take a longer time to seal and increasing energy consumption. The following are the fundamental sealing steps

Step 1: Turn the Unit on

Start by plugging the unit into a power outlet. It may be suited for 110V, 220-240V, or is dual powered. The power light will come on when switched. The heating element should heat instantly to save time and energy.

Step 2: Select the Right Temperature

There is a temperature control knob on the end of the sealer. Turning it clockwise increases the heat and rotating it anticlockwise lowers the heat. Higher heat is suited for thicker materials while a lower temperature is for lighter equipment. The heating elements will remain on briefly, usually between 2 and 3.5 seconds.

Step 3: Sandwich the Bag between the Seal Bars

Hold the item to be sealed and place the open ends of the polythene /plastic bag between the seal bars. Choose a nice margin between the object and sealed end since too much wastes the poly while too little may cause the bag to rapture. You should know the duration of the heat bar to stay on because if it goes off too quickly, then the sealing will be poor. Too long and it will burn/melt the plastic.

Step 4: Depress Handle

Once ready, depress the handle to melt the two side of the part bag. The indicator/pilot light goes off after a few seconds. Don’t remove the bag immediately after releasing the handle. This is because it will still be soft and pulling it may rapture the soft edge or leave unpleasant marks.

NB: After identifying a good piece, you should know how to operate it correctly, as shown in the video below. Apart from improved productivity and efficiency, the right usage also extends its useful life and prevents injury.

It’s preferred over other methods because it’s simple, easy to learn, works with different plastic and polythene bags, offers good protection, and also looks professionals. Nonetheless, sealers are made differently and you may not get the desired results when using the accessory.
