Hot melt adhesive is a synthetic resin that liquefies when heated and is applied with a small manual applicator or a large automated system with several automatic applicators. Adhesive tape is a filament reinforced with nylon or pressure-sensitive plastic in which a polymer is usually the primary adhesive element.
Hot melttapes exhibit significantly higher adhesion compared to acrylic tape. They have superior holding power (called shear value) and tensile strength, with a fast grip.
A hot melt tape is ideal for applications involving machine-applied tapes, overfilled cartons or cartons with a high degree of recycled content. They work well in temperatures ranging from 45°F to 120°F. Hot melt adhesive is a thermoplastic adhesive, also known as hot glue. Hot melt tapes have significantly higher adhesion compared to acrylic tape.
A hot melt tape is ideal for applications involving machine-applied tapes, overfilled boards or boards with a high degree of recycled content. Hot melt tape is a strong adhesive tape that works well on recycled and corrugated boxes. Infinity Melt CleanPack hot melt glue sticks are metallocene-based hot melt. This differs from traditional EVA in that it melts extremely clean and almost odorless.
Offers fast set time, strong initial tack and works great with hard-to-bond cardboard, corrugated, coated materials and packaging substrates. Not all packaging tapes are created equal, especially when it comes to construction. The biggest difference is the type of adhesive. The two most common ones are acrylic and hot melt.
Read on to see what makes them so different. That means that hot melt sealed packages will carry more weight and withstand more pressure than sealed boxes. For those of you who aren't masking tape experts, trying to figure out if your packages should have acrylic tape or hot melt tape may be easier said than done. In general, acrylic tapes provide users with stability over time, UV resistance to protect against yellowing, good adhesion at low temperatures and quieter unwinding.
Acrylic packaging tapes, on the other hand, offer a wider temperature range than hot melt tapes, ranging from 32° F to 140. Shurtape HP 132 and HP 232 are specially formulated with a resin and synthetic rubber hot melt adhesive that provides an instant and permanent bond in sub-zero temperatures to keep packages sealed and secured. Since the adhesive of an acrylic tape is more like a liquid, it can easily move around dirt and dust and still adhere well to the cardboard box. One of the differences is in the two types of adhesives used to make tapes stick, hot melt and acrylic.
Not only does hot melt create a stronger and more attractive bond on the packaging, it also leaves a trace if someone handles a package. It has a significantly higher adhesion compared to acrylic tape on most surfaces, including fiberboard. Hot melt tapes are hydrophobic, or “afraid of water,” so they may not work well in a humid environment. As you can see, the final application is ultimately what determines the most appropriate type of adhesive for the job.
If, like us, you are impressed by the various advantages that hot melt has over tape in case sealing and packaging construction, we have some excellent hot melt products for you to try.
