Without Glue Foil: An Ideal Choice for Printing Special Materials

At a time when materials science and printing technology are constantly evolving, without glue foil, as an innovative material, is changing the way specific materials are printed. This material, which can achieve efficient printing without the help of glue or adhesives, has a working mechanism that contains exquisite physical principles, showing many advantages that traditional processes cannot achieve, and has set off a wave of application changes in many fields. ​

Technical principle of without glue foil​
Without glue foil adopts a special molecular structure design. When applied to flocking cloth, flocking cloth with glue and silk products, its surface molecules can form a close physical bond with the surface molecules of these materials under certain conditions. During flat or roller printing, the pressure and temperature applied by the printing equipment activate the molecular chain segments of without glue foil, entangle and embed with the molecules on the surface of the material to be printed, thereby achieving a firm attachment and completing the transfer of the printed pattern. This molecular-level combination abandons glue as a medium, avoids many problems caused by the characteristics of glue, and simplifies and optimizes the printing process.​

Compatibility of flatbed and roller printing​
Whether it is the precision and meticulousness of flatbed printing or the efficiency and continuity of roller printing, without glue foil can be perfectly adapted. In flatbed printing, without glue foil is laid flatly between the printing plate and the substrate. As the printing plate is pressed down, the pressure is evenly distributed, so that the without glue foil is fully in contact with the flocking cloth, glued velvet cloth or silk products, and the molecular interaction occurs rapidly, ensuring that the pattern is clearly and completely transferred. In roller printing, without glue foil is in continuous and stable contact with the substrate as the roller rotates. With its good flexibility and fit, it can still ensure the consistency of printing quality during high-speed operation, effectively improve production efficiency, and meet the needs of large-scale production. ​

Unique advantages for special materials​
Due to the surface velvet structure and sticky characteristics of flocking cloth and glued velvet cloth, traditional printing processes are prone to problems such as uneven glue penetration and velvet lodging affecting pattern clarity. The application of without glue foil cleverly avoids these problems, directly combines molecules with the surface of the fluff, maintains the original upright state of the fluff, and makes the printed pattern full of three-dimensional sense and bright and lasting colors. Silk products are soft in texture and smooth in surface, and have extremely high requirements for printing accuracy and material compatibility. Without glue foil will not cause any damage to the delicate texture of silk, and can perfectly present exquisite patterns. Whether it is complex patterns or fine text, it can be clearly restored without affecting the luster and feel of the silk itself, and retain its high-end quality to the greatest extent. ​

Environmental protection and cost-effectiveness double harvest​
From an environmental protection perspective, without glue foil does not need to use glue, avoids the emission of harmful gases generated by the volatilization of glue, reduces the potential threat to the health of operators, and reduces the risk of environmental pollution in the production process, which is in line with the current concept of green production. In terms of cost, the purchase, storage and use of glue are eliminated, the production process is simplified, and the cost of equipment cleaning and maintenance is reduced. The efficient printing performance of without glue foil reduces the scrap rate, improves the utilization rate of materials, and can save considerable cost expenditures for enterprises in the long term. ​Without glue foil, with its unique technical characteristics and significant advantages, it brings a new solution for the printing of flocked cloth, glued velvet cloth and silk products.
