The Importance of Strength in Packaging Tapes and How They’re Tested

29 March 2022

Boxes, bottles, and other similar products must be moved and transported so they remain intact. One way to ensure their proper handling is to wrap them with packaging tape.

Packaging tapes are essential to many businesses since they can seal, wrap, enclose, and bundle items for handling, shipping, and storage. Most packaging tapes nowadays can be made from polypropylene or polyester backing due to their low costs and colour options. These tapes are then integrated with a pressure-sensitive adhesive so they can stick on the surfaces for a long time.

Picking the Right Packaging Tape

When picking the best packaging tape for an application, users must first consider several things.

One of these things is the grade. The grade of packaging tapes signifies the thickness of their backing and level of adhesive. Packaging tapes with lower grades are thin with weak tackiness, which are great for lightweight sealing. High-grade packaging tapes, alternatively, have a strong adhesive level that makes them suitable for heavy-duty sealing.

Another thing to consider is the application’s surroundings. A packaging tape may stick effectively on a specific surface. However, if it is exposed to extreme temperatures and humidity, then the tape’s overall integrity might be affected. Opting for a suitable tape ensures that it can stick around for a long time.

Ultimately, the area where the tape will be applied must be considered when picking a packaging tape. Some materials may already be sealed with standard packaging tape. Others, however, require stronger tapes to enclose and bundle them. Knowing the properties of the adhesion surface can help users pick compatible ones for them.

The Strength of Packaging Tapes

Considering all the elements above can guarantee users the best packaging tape for their applications. But before packaging tapes are even sold to the market, their strength should be tested first.

For manufacturers of packaging tapes, they must check the quality of their products so they do not break or tear easily. The quality must also be prioritised in making the packaging tapes to prevent products and other materials from getting damaged or destroyed during the handling stages.

Now, to ensure that the quality of packaging tapes will be maintained, manufacturers should have them tested. Testing them can identify the quality of packaging tapes. It can likewise confirm if the packaging tapes can meet the demands of their intended applications or not.

Packaging Tapes’ Common Tests

One test that can gauge the strength of packaging tapes is adhesion to various surfaces. This type of test examines the amount of force required before the tape can be removed from a specific substrate. Some substrates where tapes are tested are stainless steel and fibreboard. Another test that packaging tapes may undergo is holding power. It measures the resistance of the tapes to slippage.

The tensile strength test is another type of test that measures the breaking point of the tapes’ backing. Ultimately, an elongation test measures the stretch percentage of the packaging tapes before they reach the breaking point.
