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 melttapes 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 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. 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.
It offers fast set time, strong initial tack and works great with hard-to-bond cardboard, corrugated board, 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. As you can see, the final application is ultimately what determines the most appropriate type of adhesive for the job. The Infinity CleanPack bulk hot melt has little or no odor, has an extremely clean burn, has minimal carbon and offers exceptional stability in the pot. The Infinity Freezer Pack Bulk Hot Melt Freezer Pack stands up to even the coldest environments.
That means that hot melt sealed packages will carry more weight and withstand more pressure than sealed boxes. In general, acrylic tapes provide users with stability over time, UV resistance to protect against yellowing, good adhesion at low temperatures and quieter unwinding. BestPack's acrylic tape and hot melt tape are manufactured in ISO 9001 certified and ISO 14001 environmental certified facilities and are ROHS compliant. Because these adhesives are more aggressive, once applied, extreme force would be needed to cause the adhesive to separate from itself.
Acrylic tape works over a much wider temperature range and is natural for applications in hot and cold environments. In general, when it comes to deciding between hot melt tape and acrylic tape to seal a package, hot melt tape does the job in most applications. 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. Low cost but not quality, EconoPack is a hot melt adhesive made in the USA.
It is perfect for standard carton and carton closure applications.
