Types of portable heat sealers

A portable heat sealer is a packaging device that seals items like food and other products by applying heat to the packaging material. It is designed to be mobile and light enough to carry around. Various types of portable heat sealers are available, each with its features, advantages, and ideal uses.

• Impulse Sealers

  An impulse heat sealer generates heat only when the control foot pedal or hand switch is pressed. It heats up the sealing wire, which then proceeds to melt the packaging film and seals it. It is ideal for sealing food packaging parts like potato chip bags. Also, due to the low sealing temperature, impulse sealers can be used on sealable polyester, polypropylene, and polyethylene films. Impulse heat sealers come with various sealing widths and can be used for both straight and zig-zag sealing wires. Although they need electricity to operate, they can be plugged into any normal outlet.

• Constant Heat Sealers

  Unlike impulse sealers, constant heat sealers continuously heat up the sealing element, which can result in more consistent seal strengths. This portable heat sealer also has the ability to seal thicker materials with more resistance. It is suitable for high-production environments where the efficiency of continually operating equipment is needed. Furthermore, constant heat sealers can be used to seal various packaging materials like laminated and non-laminated films, foil, paper, and other heat sealable materials.

• Vacuum Sealers

  A portable vacuum heat sealer eliminates air from the package before sealing it with heat. It works by placing the item in a bag and then inserting the open end of the bag into the vacuum sealer. The machine will then suck all the air out before sealing the bag shut with heat. This sealer is ideal for preventing freezer burn in meat or any other food item. It can also be used to avoid rust and corrosion on tools and delicate electronic components.

• Pulse (or Impulse) Bag Sealers

  The main distinguishing feature of pulse/bag heat sealers is their inherent ability to control temperature and sealing time precisely. They only heat up when the impulses are given, heating the sealing element enough to melt the packaging. This allows it to provide the right pressure and temperature to get a perfect seal. The settings on this portable heat sealer can be adjusted, making it useful in industries dealing with different types and thicknesses of packaging. For instance, food manufacturers often use it because they can set it to seal packaging for fresh products and those with a longer shelf life.

• Multi-Function Heat Sealers

  Some portable heat sealers have been combined with additional packaging techniques like modification and mechanical vacuum to provide a one-stop sealing solution for businesses. Such industrial-scale multifunctional heat sealers can be relatively expensive, costing more than simple impulse sealers. They are ideal for larger commercial enterprises who have the budget to invest heavily in equipment to keep their production lines running smoothly at an efficient rate.

Specifications and maintenance of portable heat sealers

Some important specifications of a portable heat sealer include the sealing width, sealing length, sealing speed, voltage, and frequency.

• Sealing width: The width of the heat seal is determined by the heat sealer machine model. For example, handheld heat sealers like HHTS-2BL can create a 2mm seal width, which is sufficient for most applications. Other portable heat sealers can go as wide as 15mm.
• Sealing length: This indicates the length of the seals the portable heat sealing machine can make in a single run. It also depends on the heat sealing machine model. It varies from 100mm to 600mm or more.
• Sealing speed: Usually, portable heat sealers perform well at 5 to 15 seals per minute.
• Voltage: Portable heat sealers function well with low voltage ranging from 12 to 24 volts.
• Temperature: Most portable heat sealers have adjustable temperatures from 80 to 250 degrees Celsius.

Maintenance is an important part, and it makes sure the heat sealer function efficiently and prolongs its useful life. Taking care of the sealer simply involves the cleaning and inspection of it on a regular basis. Further, users can establish a schedule, or they can determine how often the heat sealer should be cleaned and inspected based on the frequency of its use.

Before cleaning the sealer, it is important to turn it off first, and then users can start removing the debris slowly, a process that is referred to as pull and whack. Try to heat the element to loosen the stuck materials, and then gently pull the debris by using pliers.

For deep cleaning, consider using a toothbrush or an air compressor. Here, users should heat the sealer and then use the air compressor or the brush to remove any residue of stuck plastic on the element.

Overall, inspecting the heat sealer is important from time to time. Look at the elements closely, and if there is any debris buildup, remove it right away. This is going to prevent any damage to the sealing wire. Also, users should check for any damage or wear. If the sealer is not functioning properly, the user should replace the parts to avoid further damage.

It's important to refer to the manufacturer's manual and guidance on how to properly clean and maintain the heat sealer. Following the instructions carefully ensures the tool is well maintained, and it enables it to operate the best performance for a long period of time.

Scenarios of portable heat sealers

The applications of portable heat sealers vary according to the type, size, and capabilities of the sealer.

• Packaging industries: In retail packaging, a portable heat sealer for bags helps pack and seal food items like chips, candy, groceries, coffee, and other perishable goods to prevent tampering and ensure customers get fresh products. Also, in water bottle production, heat sealers apply bottle caps or seals to ensure the product is untouched and leak-free.
• Food service: Restaurants, catering services, and food trucks frequently use heat sealers to package takeout meals, snacks, and frozen goods. By heat sealing food containers or pouches, they can extend shelf life, preserve freshness, and provide customers with secure packaging.
• Postal and shipping: Heat sealers securely seal packages, envelopes, and labels in logistics and shipping. Heat-sealed packages are safer, ensuring items arrive intact and unrevised.
• Electronics and manufacturing: Heat sealers help to neatly package delicate electronic parts and components like circuit boards, sensors, and connectors. Heat-sealed bags provide antistatic protection and contamination prevention for these sensitive items.
• Construction and landscaping: In the construction industry, heat sealers help in packaging construction materials like insulation, vapor barriers, and protective tarps. Heat-sealed joints ensure integrity and prevent leaks in crucial building components.
• Personal care and cosmetics: Cosmetics companies and personal care brands use portable heat sealers to package skincare products, makeup, and toiletries. Heat-sealed containers ensure product integrity, prevent leakage, and maintain hygiene.

How to Choose Portable Heat Sealers

When buying items for retail, buyers need to get heat sealers that will meet clients' needs. The first step in selecting is to identify the intended use. What type of packaging will the portable heat sealer be used on? Ensure the portable sealer chosen can handle the most needed packaging material. For example, when sealing flimsy plastic like polypro or polyethylene, a buyer should choose an impulsive heat sealer distinctive for lightweight materials.

Also, consider the variety of heat settings the sealer offers. Different types of packaging materials require specific heat levels for effective sealing. Having a machine with adjustable temperatures can enable one to experiment with different levels until the most suitable for the packaging is found. Ideal sealers have at least five different heat settings.

Another key consideration is the size and weight of the sealer. Choose a sealer that is small and light enough to be able to hold, and move around, or stow away when not in use. Heat sealers generally come in different sizes and weights to suit different portability needs. Since portability is an important factor, choose a unit that is conveniently portable. When possible, test the portability of the sealer before purchasing.

When purchasing items in bulk, buyers should consider the energy efficiency of the heat sealers. They should look at models that have energy-saving features, like auto shut-off after a specified idle duration, and low energy consumption. Apart from optimizing operational costs, energy-efficient sealers can help to reduce environmental impact.
