The Beginner's Guide to Creating Strong & Airtight Seals Using a Manual Heat Sealer.
Manual impulse sealers are a must-have for small businesses and individuals who need to package products on a regular basis. Known for their versatility, compact size, and ease of use, these bag sealers provide a quick, easy, and affordable way to seal a variety of bags and shrink-packaging rolls or pouches - including those made of plastic, polypropylene, and other heat-sealable materials. Plus, their size and portability make them perfect for businesses that have limited space or need to move the sealer between different locations.
These packaging machines are used across many industries to seal food products, electronics, jewelry, and much more. Home business owners who sell baked goods, crafts, and other homemade products can also benefit from using a manual heat sealer. By packaging their products properly, they can protect their goods from damage during transport or storage and make them more attractive to potential customers.
In this step-by-step guide, we'll cover all the basics of using a manual impulse sealer - including how to position the machine for optimal results, how to prepare your bags for sealing, and how to adjust the seal time to achieve the best possible seal. By following these simple steps on how to use a manual impulse sealer, you can enjoy the benefits of your sealer for years to come.
STEP 1: Choose the Right Heat Sealer for Your Application
When looking for a manual impulse sealer, there are many types available on the market - each with its unique features, capabilities, and sealing dimensions. It is important that you choose a machine that suits your budget and packaging needs. Before purchasing a heat sealer, consider factors such as the size, thickness, and material of the bags you will be using. For small bags, a compact yet mighty sealer like our MMS-100 will do the job. Larger products may require a hand sealer with a larger sealing area - like our MMS-500 or the extra long MMS-1000-H. You should also think about how frequently you will be using the sealer, as well as the the width of the seal. Most impulse sealers have a standard 2mm sealing element. If you're looking for an extra thick seal, go with an impulse sealer equipped with a wide 5mm seal. Last, consider whether you would benefit from a sealer with a cutter. Taking these factors into account will help you choose a sealer that meets your specific requirements and ensures your packaging is secure and professional-looking.

STEP 2: Find a Work Area & Position Your Machine
To ensure your safety and the safety of those around you, place your machine over a flat and level surface that is free from liquids or flammable materials. This will prevent the sealer from tipping over or being damaged during use. Additionally, make sure you consider the ergonomics of your workspace. Position your machine at a comfortable height for you to use, and make sure that the handle is within easy and comfortable reach to reduce the risk of strain or injury.
Before using your manual impulse sealer, check that the power cord is in good condition and that the power source you will be using is the correct voltage for your machine. Connect the unit only to a suitable power source to prevent any electrical hazards that could arise from using the sealer with an incompatible source of electricity.
STEP 3: Fill & Prepare the Bag
The preparation of your heat-sealable bag is crucial to ensuring a strong and lasting seal. Make sure your bag is clean and free of debris before placing your product inside. Dirt, dust, and other contaminants could potentially interfere with the sealing process, causing weak or incomplete seals that may leak during storage or transportation.
Once your bag is clean and ready, position it carefully over the sealing area. Any irregularities in the surface of your bag can create gaps or weak spots in the seal. This can compromise the freshness and quality of your product, leading to customer dissatisfaction and lost revenue. Before sealing, double-check for any wrinkles, folds, or creases that could interfere with the sealing process, and make sure the bag is lying completely flat and even on the seal area.
STEP 4: Adjust the Sealing Time
The manual impulse sealer is a versatile tool, known and used across many industries to seal a range of bags and packaging materials. One of the key features that makes them so adaptable is their adjustable seal timer. This timer allows you to create a strong and airtight seal - regardless of the thickness and material of your heat-sealable bag - by regulating the amount of time heat is applied during the sealing process.
Sealing times vary from bag to bag. Many bags, like those made from thinner materials, can be effectively closed with just a quick blast of heat. For thicker bags, a longer seal time may be needed to create a secure and long-lasting seal. You'll want to adjust your sealing time based on the type of bag you will be sealing. A short seal time may produce weak or incomplete seals, which could result in leaks or damage to the product inside. On the other hand, if the seal time is too long, the bag may become too hot, which could cause it to melt or warp.
An impulse sealer's timer knob is usually located at the front of the machine and can be easily adjusted by turning it to the appropriate setting. To determine the right seal time for your bags, it may be helpful to test different seal times on a sample bag before sealing your entire batch. Start with a shorter seal time and gradually increase it until you achieve a strong, airtight seal. Keep in mind that seal time may also depend on factors such as the temperature and humidity of your workspace - so make adjustments as needed.
STEP 5: Seal the Bag
Now that you have positioned your bag correctly and adjusted the timer, it's time to seal the bag. To do this, place your hand over the handle and lower the sealing jaw. Apply enough pressure to ensure that the handle arm is squarely and completely in contact with the lower unit. This will activate the sealer and energize the heating element.
When the sealing jaw makes contact with the lower unit, a small light will turn on under the sealing timer knob, indicating that the machine has begun sealing. Hold the handle down until the light turns off. When the light turns off, the seal is complete. Allow the bag to cool down for a few seconds before releasing the sealing jaw. This will prevent any accidental tearing or damage to the seal. Once the seal has cooled down, release the handle and take the bag out.
STEP 6: Inspect the Seal on Your Bag
After sealing your bag, take a few seconds to carefully examine the seal for signs of damage, leaks and other defects. This will ensure that your products are always protected during storage and transportation. If you notice any issues with the seal, take the necessary steps to adjust the seal time or handle pressure and try again. Inspecting your seals can also help identify any underlying issues with your sealing machine as well, such as overdue maintenance or a worn-out sealing element. By regularly inspecting the seal and making adjustments when necessary, you can ensure that your sealing process is efficient and reliable, and your products are well-protected.
BONUS STEP: Don't Forget to Keep Up with Your Hand Sealer's Maintenance
To keep your manual impulse sealer running smoothly and performing at its best, it's important to keep up with its regular maintenance. Start by keeping the machine clean and free from debris or residue. Wipe it down after each use and regularly remove any buildup on the sealing element or Teflon tape.
Check the sealing element and Teflon tape regularly for signs of wear or damage. If the sealing element is cracked, damaged, or worn, it will need to be replaced. The Teflon tape, which is designed to protect the sealing element, should also be replaced periodically to ensure a strong seal.
By performing regular maintenance, you can keep your manual impulse sealer in top condition. This will ensure that it continues to provide reliable and consistent sealing for your business.
