Heat Seal Packaging

Heat Seal Packaging

Can you imagine purchasing a product – perhaps a food item – that is not sealed?

I am sure you must be surprised at even the thought of this.

All items must be sealed, and no perishable with a broken seal should ever be purchased.

Yet, have you wondered how does the sealing process take place?

Sealing is as vital to packaging as water is for us. Let’s explore one way of sealing packaging: heat-sealing.

Heat Sealing

A heat-sealing machine is used to seal products that use heat as the medium.

Packaging products are heat-sealed when the heater ribbon, present on the device surface, is subjected to abrupt but extreme current impulses.

The heat-sealing process is used to join multiple, similar materials.

Dissimilar materials can also be joined through this same process, as long as at least one material contains a thermoplastic layer to allow the joining.

Heat sealing has numerous applications and is mainly used in producing packaging supplies for packaging food.

Other industries that utilize heat sealing include medical packaging boxes, construction, and manufacturing.

Let’s look at some of the benefits of heat seal packaging and the entire heat-sealing process:

  • The heat-sealing process is quick and does not involve much waiting:

The actual process is swift, once the device is ready for use.

You can heat the sealing bar almost immediately, and the user does not have to wait for long. Before you know it, the heat-sealing process is complete.

  • Alternative sealing options are time-consuming:

Going for a different sealing option costs time and energy that could have been put to better use.

Moreover, the wastage of power results in excessively high electricity and labor costs, as well as inefficiency.

Conventional sealing devices require a considerable amount of time before they are ready to use. On the other hand, their modern counterparts heat up instantly, saving hefty power bills and valuable employee time.

  • With heat sealing devices, no gadget components are hot at all times:

The components are only hot while they are being operated.

Since they do not retain this heat once the sealing process is over, they reduce the possibility of accidents and injuries during work.

Traditional options have hot sealing bars which are usually left on, and often lead to accidental burns and even more significant injuries amongst the workforce.

With heat sealing, you can be assured that the machine is not hot, and therefore, safe to use.

  • The aluminum sealing frames assist in the cooling process:

These sealing frames indicate the end of the cooling process, and that the user can now collect the package for ideal sealing results.

This means that the eventual seal is neater and sturdier.

On the other hand, orthodox sealing procedures, the cooling and sealing takes place simultaneously with shrinking.

The result is an uneven packaging supply, lacking in neatness and cleanliness when compared to the contemporary models.

  • Heat sealing ensures that the package remains airtight:

This can be observed in products such as cooking oil, which is available in sachets, and the popular packets of potato chips.

Making sure that the material inside the packaging product remains airtight, helps protect it against external damaging factors such as moisture or UV rays.

The result is a product that is safe for the public to use, leading to reduced possibilities of legal actions and defamation due to product contamination.

There are several advantages associated with the heat-sealing process; mainly safety, ease, pace, and cost-effectiveness.

Along with these benefits, product protection and consumer satisfaction have made the heat seal packaging style extremely popular amongst numerous, diverse industries.
