Hot melt packaging had become mainstream in the 1960s. Hot melt adhesive is a commonly used method in the packaging industry. It is usually used for closing cartons, sealing and stabilizing pallets, etc.
Overview of Hot Melt Adhesives in Packaging: In the 1960s, hot melt adhesives became common in packaging and processing applications. The main advantage of using hot melt adhesive is that its adhesive force is greater than that of water-based adhesives. Hot melt adhesive is also superior to water-based adhesives because it has a shorter curing time, better water resistance, and can reduce packaging lines/space. The next major advancement in adhesives for the packaging industry came in the 1980s with the development of PUR hot melt adhesives. PUR has stronger adhesion and better aging resistance than traditional hot melt adhesives.
Why is hot melt adhesive so suitable for packaging? Hot melt adhesives can bond small and detailed cartons to heavy-duty packaging boxes. It is highly suitable for bonding all types of packaging because the various formulas available can easily meet the requirements of various applications. Hot melt adhesive not only has high heat resistance, but also has a formula that can withstand temperatures as low as -40 degrees Celsius and humid environments. There are various types of packaging materials, but even so, it does not affect the use of hot melt adhesive, as it can firmly adhere to all types of paper, cardboard, plastic and various other substrates. Hot-melt products can be provided in bulk, making them cost-effective.
Overall, hot melt adhesive is a better choice for sealing and erecting shells. Its uses in packaging: sealing boxes, sealing, and stabilizing pallets. Hot melt adhesives are cost-effective. When used with hot melt systems, they can operate continuously without having to stop and refill the tape rolls. When the shell is sealed and erected with hot melt adhesive, the adhesive will be applied to the flaps, thus forming a strong bond. This bonding helps the box remain intact and strong during transportation.
Direct answer: Choose a fast curing grade with short opening time and high initial adhesion The biggest fear for graphic and text fast printing shops is that customers will say ‘get it in an hour’. To ensure that the bidding documents and sample books can be cut and bagged after being glued, it is necessary […]
Direct answer: Polyurethanehot melt adhesiveParticles (PUR) are most suitable for three types of scenarios – wireless adhesive packaging for high-end hardcover books and photo books, export paper boxes that require high and low temperature resistance, and photo albums and sample books with zero tolerance for glue opening. It forms a cross-linked structure through moisture curing, […]

Is it more cost-effective to bind the instruction manual with saddle nails or glue? One sentence conclusion:Thin pages and small batch selection of saddle nails are more cost-effective; Having multiple pages, requiring high-end or long-term storage, the overall cost of adhesive packaging is better.The selection of manual binding should not only consider the processing fee […]
