Heat Sealers

Industrial Heat Sealers

Promarks makes the most advanced heat sealer with patented technology.

The Promarks series of commercial heat sealers were designed with the user in mind. The ideal solution for small processors, retailers, restaurants, and laboratories, these items are affordable enough to be purchased simply as a backup while maintaining the superior quality that one can rely on during years of heavy use. Primarily used for preserving fresh meats, industrial heat sealing has been found to be beneficial in other industries such as pharmaceuticals and electronics, so Promarks products are finding their way into all sorts of industries.

What is a quality Heat Sealer?

The material bond and seal quality of a thermal seal relies upon multiple elements, including time, temperature, pressure. Seals must be sufficiently solid to withstand the rigors of any supply chain while protecting the contents from contaminants. Enhancing the warmth fixing process and reliably creating bundles with the suitable seal quality is of basic significance since it can directly affect item adequacy and patient security.

Dwell Time

Sealing time alludes to the time the warming components of a bundling procedure (clips, plates, bars, and so forth.) are in coordinate contact with the substrate(s). It can be it is possible that uneven or two-sided warming. The two materials meet up to frame a bond or seal. It is imperative to see how the gear measures the stay time to decide "genuine abide time," which is the point at which the networks are really squeezed together. That is on the grounds that control for warm fixing gear shift and process duration could conceivably incorporate travel time for the machine to draw in into its last shut position. Any variety in the rates of materials achieving their seal start temperature, even by divisions of a moment, can measurably affect seal quality.


The warmth fixing process, as beforehand portrayed, weds two materials and makes a bond. To accomplish this bond, one of the materials normally conveys a surface sealant layer. The warming components of warmth seal bundling hardware are raised to a temperature sufficiently high to either liquefy or initiate the sealant.

The essential heal seal variables of time, temperature and weight are intelligent. A change or change in one commonly requires a change or change in at least one of alternate variables. A harmony between time, temperature and weight must be met to accomplish the coveted seal quality and visual seal exchange. Temperatures must be sufficiently high to actuate the sealant layer, while not overheating the surface of the material.

It is prescribed to streamline the warmth fixing process utilizing apparatuses, for example, Design of Experiments. This not just outcomes in a warmth fixing process that reliably delivers adequate seals, yet in addition, can streamline vitality yield and operational throughput and efficiencies.


The third key factor of warmth fixing is the weight at which the hardware units and holds the two materials together to frame the seal. It is vital to know the real weight the substrates are presented to in light of the fact that this esteem is frequently not identical to the information weight or the setpoint on the machine controls. There are numerous procedures to quantify fixing weight—from sensor paper to more advanced electronic sensor innovations. For most warmth seal materials, weight is the slightest huge of the three components required to influence a warmth to seal.

Various and Other Factors for Heat Sealing

The three fundamental variables for warm fixing—stay time, temperature and weight—can deliver noteworthy fluctuation in seal quality. Nonetheless, there are different components identified with time, temperature and weight that can likewise influence warm seals. Some normal components include:

Variety in platen temperature—"problem areas" or "cool spots"

Non-uniform warmth exchange because of uneven contact or weight caused by a distorted or misaligned platen

Material thickness or variety
