Plastic Tube Sealing – Make The Right Choice!

Your choice of plastic tube sealing is actually more important than you may think. How you seal your plastic tube can make or break your product and affect your customers user experience of your item.

While you may have put a lot of time and thought into choosing the best type of packaging tube that will deliver your product efficiently, carry your branding and ingredients label – and also look good, your plastic tube sealing options are also worth just as much careful consideration.

You will need to choose the right seal that will deliver good strength and reliability, but also doesn’t negatively impact on the final aesthetics of your product.

Most popular plastic tube sealing options

Let’s take a look at the most popular tried and tested methods of plastic tube sealing options that meet with industry standards for safety, quality and performance.

Hot Air Tube Sealing: The most popular choice for both plastic and laminate tube sealing. This method delivers a strong seal along with a neat and tidy appearance. Ideal for products that will be put on display without extra packaging.

Ultrasonic Tube Sealing: This sealing method uses high frequency vibration technology to heat the plastic material of the tube in the sealing area. The melted plastic is then closed together under pressure between a sealing horn and anvil component. The finished seal is not as visually appealing as hot air tube sealing.

Hot Jaw Tube Sealing: Heated crimping jaws are used to apply both heat and pressure to the sealing area of the plastic tube to create a seal. The heat is applied externally and works its way into the inner tube walls. The finished seal does not give such a professional look, but is fine for tubes that are going on to be further packaged into display boxes.

Tube type and choice is important

To benefit from the above tube sealing options you need to make sure that you choose the right type of tube that will be suitable for your preferred sealing choice and machine capabilities.

When faced with choosing between either extruded mono/coex, laminate, injection-moulded – and more tubing choices, it can become a little confusing and overwhelming to know which tube will be the best for your product.

We all know that the look of your finished product will need to be visually appealing as well as effectively sealed to ensure your customer is delivered with a high-quality product experience, so your chosen method of tube sealing will impact greatly on the look and feel of your tube.
