Choosing the Right Heat Sealer for Your Needs

 



When looking for a sealer, it is essential to have a solid understanding of the material that will be sealed. You should make every effort to have the material's thickness as well as its width available, as this will make the process of selecting it much simpler. This will ensure that the sealer you select is able to effectively seal the material you need to seal. If you would like some recommendations for sealers, please complete out this little questionnaire, and we will get back to you with some recommendations.

On this page, the four most significant characteristics of sealers are discussed so that you can select the product that is most suitable for your needs.

 


To begin, let's define a heat sealer.
A heat sealer is a machine that is used to seal plastic material using heat. Other names for this type of machine are bag sealer, heat impulse sealer, direct heat sealer, and hand sealers. There are many different kinds of sealers, and picking the proper one might be challenging if you don't have an understanding of a few fundamental principles.
Function

 

What is the difference between band sealers and vacuum sealers


There are primarily two kinds of sealers: (1) those that use impulse heat, and (2) those that use direct heat.

Impulse sealers don't need any warm-up time before they can seal, and they do it by applying a pulse of energy to the sealing region, then instantly cooling it off again. Only when the jaw is brought down does an impulse sealer use any power. Any thermoplastic material, such as polyethylene (PE) or polypropylene (PP), which requires a lower seal temperature, should be sealed using an impulse sealer, which is what we recommend. Materials that can be used with impulse sealers include polyethylene, polyurethane, polyvinylchloride, pilofilm, polyvinyl alcohol, saran, nylon, bubble packs, padded mailers, foil, coated bags, Kel-F, Polyflex, Mylar, Tyvek, and any other thermoplastic material. Impulse sealers are simple to operate (there is no need for a warm-up period), cost-effective (electricity is only utilized during the actual sealing operation), and safe (no component is always hot).

 

 



There are several distinct categories of impulse sealers, each of which is designated for a specific kind of material and application:

Sealing poly material with a hand sealer is possible for thicknesses up to 10 mil.
Sealing poly material with a pedestal type or foot sealer is possible up to a thickness of 15 mil.
Sealing poly material with a thickness of up to 15 mil is possible using auto sealers.
Sealing poly material with a thickness of up to 20 mil can be done with double impulse sealers, which come with both automated and foot options (we recommend double impulse for heavy duty applications).
In order to create individualized bags, sealers that are equipped with cutters are used to both seal the bags and trim away any surplus material (tubing).

Sealers that use direct heat (also known as steady heat) keep the temperature in both jaws at a consistent level. Sealers that employ direct heat use power for the duration that the device is operational. As a consequence of this, direct heat sealers have better heat penetration in rods, which enables them to seal materials that are far more robust. We recommend using a direct heat sealer for materials such as coated aluminum foil, poly cello films, gusset bags, coated Kraft papers, waxed paper, cellophane, mylar, coated PP, and any other materials that are more substantial.

We also include different kind of sealers that are utilized for a wider variety of applications, including:


Before vacuum sealing a product, air must be extracted from it so that the product can be enclosed in an airtight container. In order to prevent oxidation, spoilage, or corrosion, we propose vacuum sealing the product in question. Because PP and PE bags both have pores, they are not suitable for long-term storage and so must be replaced by barrier bags.

Sealers designed specifically for clamshell packaging are ideally suited for welding clamshell containers.

Size

The breadth of the material that needs to be sealed will determine the size of the sealer that is needed. In order to make the material to be sealed simpler to handle, we often suggest adding one inch to the breadth of the material. The sealer's cutters typically trim at a distance that is marginally narrower than the width of the sealer arm.

Speed
Sealers that are portable are lightweight, convenient, and adaptable. However, there is a restricted offering of sizes.
Hand sealers are the most straightforward and cost-effective equipment available. The bar that seals the opening is lowered by hand. There is a range of sizes available, from four inches to forty inches, and around six to twenty parcels may be sealed in a minute.
Foot sealers give a seal that is achieved far more quickly than hand sealers. Because the sealing bar is controlled by a pedestal, you will not need to use your hands. There is a range of sizes available, from 12" to 35", and the rate at which packages can be sealed is roughly 8-20 per minute.

Sealing may be accomplished with automatic sealers even more quickly than with foot sealers, making them an excellent choice for applications requiring a high volume of production. Tabletop sealers are the most common type of automatic sealer. These sealers include jaws that are operated automatically by a sequence timer that is controlled by a dial. Sealers that are automatic have a pre-set time cycle that allows for a fully continuous functioning of the automatic function. Sealers that operate fully automatically can also be operated semi-automatically by use of a foot pedal. There is a range of sizes available, from 12" to 47", and the rate of sealing at around 20-50 packages per minute is impressive.
Sealing operations performed by continuous band sealers are the quickest and can be performed over an endless length. Bags are simply placed on a conveyor line and fed into the sealer as they remain there. A variety of versions can be purchased, each of which may come equipped with features such as a horizontal seal head, a vertical seal head, a tilting seal head, left or right feed, gas purging, and/or coding and imprinting capabilities.
The width of the seal or the material being packaged

The breadth of the seal is determined by heating elements that are composed of nichrome, which is made of nickel and chromium. In most sealers, you can choose between round and flat heating elements. These elements are interchangeable with one another. The primary function of the round wire is to cut and seal such that there is no surplus material above the seal. Sealers can be purchased in widths of 2-3 millimeters, 5 millimeters, 8 millimeters, or 10 millimeters, depending on the diameter of the flat wire element. Some sealers feature two separate heating components, which allows for greater heat penetration and makes these particular models excellent for sealing more substantial materials.
