Handheld sealers are portable sealers that are designed for packaging purposes. They are ideal for both small bags of thick materials and larger bags. The bags stay outside the machine, and the air is removed from it by suction through a special valve. They are usually cordless and rechargeable and much smaller than regular countertop models. If you plan to purchase a handheld sealer online, you may also need to buy sealer-friendly bags for packaging the relevant merchandise.

Handheld sealers are comparatively cheap. They are economical devices that offer an inexpensive method of vacuum sealing, which only takes a few seconds to seal the bags tightly. So, if you want to purchase handheld sealers online, here are some basics to know about.

Benefits of Handheld Sealers

● Compact and lightweight: Handheld sealers are easy to pick up and move. They only require a power outlet and maybe an extension cord.

● Custom shapes: you don't have to worry about bag sizes and odd-shaped items. This means you can create custom seal shapes.

● Easy to use: you can simply plug in the sealer and start to use it. Many models also come with a dial, which is extremely easy and quick to use.

● Flexible options: you can choose the best option for you by electing the right material compatibility, seal length, heat style, and price point.

Handheld sealers offer the ultimate combination of sealing capability, portability, and production flexibility. They are lightweight and versatile. They also do not require you to consider the sealing width of your package. You seal small bags in a single seal and create overlapping seals for closing odd-shaped or large bags.

These portable sealers can create custom and unusual seal patterns. They also offer the ease of creating double seals for extra oxygen and moisture barrier protection. This eliminates the need to bring the packaging to the sealer. Using an extension cord can help you to carry them anywhere the length of the cord permits easily.   

How do Sealers Work?

Handheld sealers use heated seal wires that are activated when the seal bar is pressed close. The sealing bar forces the wire and the film to melt the seal-forming material and mend it. The silicone sealing pad can withstand direct heat contact. These sealers use heat as a medium for sealing components and work by producing the heater ribbon on the surface of the system with a high current impulse. This creates a heatwave that is intense enough for the sheet to be pressed between the sealing bars to melt and seal up.

Types of Handheld Sealers Available

● Impulse hand sealers with flat or round wire: These are highly reliable and durable hand sealers. They provide durable seals for almost any sealable plastic film. They are suitable for polypropylene, polyethylene, PVC, polyolefin, polyplex, polyurethane, mylar, Tivac, P.V.A., Pliofilm, Kel-F, Nylo, Saran, etc. The sealer comes with wire replacement parts. Flat wires are mostly used for tubing or poly bags as they provide cutting and sealing in one step, which means no extra clutter. These sealers also produce the seal at the right angle without a lip.

● Flat wire impulse hand sealer with cutter: The properties of these sealers are the same as the previous one. But the only difference is that it comes with a built-in sharp blade that can be used to cut excess material a quarter inch from the seal.

● Stainless steel impulse hand sealer with cutter: This sealer has all the features of an ordinary sealer. But it comes with a stainless steel cover that provides waterproof protection. They are also easy to clean and good for seafood packaging. It also comes with a built-in sharp blade like the previous sealer.

● Portable impulse hand sealer: These are high-quality sealers that work just like other models. They are made of sturdy steel but are lightweight structures with a carrying handle. The kit includes a sealing timer and replacement parts. You can choose either round wire for cutting and sealing shrink-wrap bags or opt for a flat wire that provides a 2mm wide seal.

Difference Between Handheld and Countertop Sealers

Both types of sealers have the same goal of sealing packaging bags. But you need to choose the one that will best fit your needs and how often you intend to use it. Countertop sealers have one small drawback: when you open and close the bag, you need to cut the edges where it is sealed. If you re-seal it, the bag may get smaller. Also, they are more expensive and large compared to the compact handheld offerings. But countertop sealers can give extremely durable seals that can never fail. But these are heavy and not portable.

Takeaway

To buy the best sealers, you need to look for the leading provider of high-quality sealers that value their reputation. Make sure all sealers the suppliers offer are thoroughly tested for defects. Also, ensure that you get a warranty with any hand-held sealer, which includes parts and repairs.
