Hot melt adhesive is a synthetic resin that liquefies when heated and 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 melt
tapes exhibit significantly higher adhesion compared to acrylic tape. They have superior holding power (referred to as shear value) and superior tensile strength, with fast adhesion.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 tape is a strong adhesive tape that works well in recycled and corrugated boxes. Hot melt adhesive is a thermoplastic adhesive, also known as hot glue.
Hot melt tapes have a significantly higher adhesion compared to acrylic tape. A hot melt tape is ideal for applications involving machine-applied tapes, overfilled cartons or boards with a high degree of recycled content. 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. Often, lower quality tapes offer thinner backings and lower levels of adhesives, making them ideal for sealing lightweight boxes. Shurtape HP 132 and HP 232 are specially formulated with a resin and synthetic rubber hot melt adhesive that provides an instant, permanent bond in sub-zero temperatures to keep packages sealed and secured.
Read on to understand the fundamental differences between hot-melt carton sealing tapes and acrylic packaging tape, and what to expect from both. It is recommended for applications where hot melt will remain in pots for extended periods of time or where charcoal and stringing have been a problem. In the past, acrylic tapes were the choice for these applications, as hot melts were almost impossible to apply because their adhesive hardened too quickly. One of the differences is in the two types of adhesives used to make tapes stick, hot melt and acrylic.
The material used in the tape is a rubber-resin adhesive, so it is slightly more expensive compared to acrylic tape. Acrylic packaging tapes, on the other hand, offer a wider temperature range than hot melt tapes, ranging from 32°F to 140. In general, acrylic tapes provide users with stability over time, UV resistance to protect against yellowing, good adhesion at low temperatures and quieter unwinding. The best option is tapes that offer easy unwinding to reduce tension caused by stretching and tearing, instant adhesion to allow immediate palletizing, and excellent holding power to allow cardboard seals to withstand the stress applied by overfilled cartons, processes automated pick-and-place or palletization.
transit and storage. In addition to the proven speed and cost benefits, hot melt can create a strong, continuous bond along each packing seam to which it is applied.
