What is the Difference between Acrylic Packing Tape and Hot Melt Shipping Tape

Posted by in Type of Tape on November 26, 2014

We get this question all the time. Hopefully the below explanation will help differentiate the two.

Acrylic Packing Tape

Acrylic packing tape is your best bet for storage boxes. Acrylic adhesive can handle a variety of temperatures and setting, including warehouses, garages and storage facilities. Plus, acrylic packaging tape can maintain its seal for more than three years.

Thickness: commonly 25 micron but can be thicker with polypropylene backing.

Acrylic tape resists drying up in sunlight and is resistant to UV Exposure from warehouse skylights. Traditionally this tape is recognized as being a good adhesive to plastics as well.

Hot Melt Shipping Tape / Synthetic Rubber

Hot melt shipping tape / synthetic rubber is the best for shipping boxes because of its superior holding power.

Shipping boxes are typically subjected to rough handling in transit. Hot melt packaging tape ensures your boxes stay sealed. You can also use hot melt tape to strap boxes together.

The glue starts out as a solid that is heated (hot melt) to a point where it runs, chemicals are added to keep it soft and sticky. This adhesive is affected by extremes in temperature so in hot temperatures the adhesive can become soft and creep allowing the carton to pop open particularly where the tape is incorrectly stretched onto the carton.

When used in a colder climate the adhesive tends to harden and lose tack. Good for machine tape especially in high volume light weight packaging such as food packaging as the tape unwinds easily and doesn’t rely on the weight of the box to pull the tape from the roll.

This tape is ok to use in fridge/cool room situation if it has been applied by machine in ambient temperature then transferred into the cool room as the adhesion should not change.

Hot Melt adhesive dries quicker than other tape types so it is not suitable for long term storage.
