Have you also encountered these binding difficulties?
After binding copperplate paper picture books and magazines, the spine of the book is prone to peeling and falling pages; On high-speed production lines, colloidal wire drawing scratches dirty paper, resulting in a high rework rate; After being stored for a period of time, the spine of the book turns yellow and brittle at low temperatures, leading to continuous customer complaints
Most of these issues are due to not choosing the right specialized hot melt adhesive that is compatible with copperplate paper! Today we will start with the key points of industry selection and market pattern, helping you find the most suitable solution.


1、 Choosing the right hot melt adhesive for copperplate paper is the key


The smooth coating on the surface of copperplate paper places higher demands on the permeability, adhesion, and stability of hot melt adhesive, which is difficult to meet with ordinary hot melt adhesive. When choosing glue, it is important to pay close attention to these points:
Priority for substrate adaptation: 80-200g copperplate paper, special formulas (such as HJ38C, Senlai copperplate paper adhesive) must be selected, and ordinary adhesive cannot guarantee adhesion strength.
Core parameters must meet the standards:
Softening point: 82-88 ℃, balancing low-temperature anti brittleness and high-temperature anti sticking;
Viscosity: 4000-8000cps@170 ℃, balance fluidity and adhesion;
Open time: 8-20 seconds, suitable for different production line speeds.
Environmental certification is essential: priority should be given to products that have passed SGS, China Environmental Labeling, and FDA food grade certification to avoid risks caused by odors and harmful substances.


2、 The market landscape in 2026, these enterprises are worth paying attention to


At present, the domestic hot melt adhesive production capacity is concentrated in the East China region (accounting for 68%, of which Zhejiang accounts for 39.2%), with Guangdong and Shandong accounting for 15.6% and 13.4% respectively. The mainstream price of EVA particle hot melt adhesive is 16-18 yuan/kg (25kg/bag).
Top enterprises such as Guangzhou Senlai (Foshan Jucai) are more popular, among which Guangzhou Senlai (Foshan Jucai) in our southern region has become a popular choice for customers in the printing industry.


3、 Why do we strongly recommend Guangzhou Senlai (Foshan Jucai)?

    No yellowing: The formula is stable and resistant to carbonization, and the spine remains white and clean even after long-term storage;
    No glue opening: By adjusting the opening time and curing speed, it is suitable for all paper types from 60g adhesive paper to 250g copperplate paper, even for hardcover picture books and children’s picture books, it can achieve 180 ° flat spreading without glue opening.
  2. Stable production capacity+customized services to meet the needs of customers of different scales
    With an annual production capacity of nearly 6000 tons and a production base of 3000 square meters, it can stably supply large quantities of books, periodicals, and graphic printing orders;
    Support formula customization, adjust colloid parameters according to your production line speed, paper weight, and binding equipment, and provide exclusive solutions.
  3. Environmental compliance+quality certification, use with confidence
    All products have passed the China Environmental Labeling Certification, with VOC content far below the national standard requirements. No harmful substances such as formaldehyde and benzene were detected at a working temperature of 180 ℃. Whether it is children’s picture books, food packaging supporting books and magazines, or high-end picture books, they can all meet environmental and safety requirements. Simultaneously certified by ISO9001 quality management system, the quality is fully controllable throughout the process.
