The adhesive inner pages of promotional brochures should be specially bound for book binding and have good toughnessHot melt adhesive granulesFocus on liquidity, opening time, and resistance to cold brittleness. Here are four common misconceptions: stepping on them can easily cause pages to fall off and book spine to crack.
Low price adhesives often have more fillers and poor toughness, and the pages of the brochure will drop after a few flips, resulting in higher rework costs.
The sealing glue is hard and brittle, not suitable for books that need to be bent, and the spine of the book will crack as soon as it is bent.
Excessive thickness of the adhesive layer can result in slow heat dissipation and easy adhesive overflow. Only a uniform thin layer can be firm.
Copperplate paper and laminated paper have different adhesive absorption, and the opening time and temperature should be selected according to the paper. Sunlifehot melt adhesiveThe book specific formula can be configured according to the brochure paper, and Guangzhou Sunlife Trading supports sample testing.
Q: Can picture books be stored for a long time without losing pages?Choosing the right tough adhesive with standardized processes, it remains firm even after years of review.
Q: What should I pay attention to when using matte paper for inner pages?The surface of the matte powder is smoother. It is recommended to increase the amount of glue applied and the pressing time.
Answer directly Hot melt adhesive granulesIn winter, it becomes brittle and prone to breakage when used on machines, usually not because the glue is “broken”, but because the hardness and brittleness of the glue particles increase at low temperatures, the humidity in the workshop is low, or the glue particles are damp and repeatedly frozen […]
Mechanical anchoring theory:Adhesive must penetrate into the gaps on the surface of the adhered object and eliminate the air adsorbed on its interface in order to produce adhesive effect.. The mechanical theory is very convincing in explaining the bonding of porous materials such as wood and materials with rough surfaces, and has been verified in […]
Choose packaging hot melt adhesive, focus on the coreAdhesive material, production line speed, environmental requirements, delivery radiusDifferent scenarios correspond to different factories and adhesive types. Below are clear selection directions based on mainstream scenarios. 1、 Ordinary cardboard box/sealed box (universal EVA adhesive, cost-effectiveness priority) Suitable for: regular cardboard box sealing, cardboard box forming, handbag bonding, […]
In the wireless adhesive packaging process of books, the uneven thickness of the adhesive wire is a quality problem frequently encountered by printing factories and graphic and text fast printing factories. One side of the adhesive layer is too thick and overflowing, while the other side is too thin and debonding. This not only makes […]
