Routine Testing of UV Tobacco Packaging Ink Performance

Routine Testing of UV Tobacco Packaging Ink Performance

As consumers increasingly demand higher standards for product packaging quality, the processes involved in tobacco packaging have become ever more complex and sophisticated, driving a corresponding rise in the pursuit of superior print quality. This trend has, in turn, spurred continuous optimization of printing ink performance. As a special type of printing ink, UV ink plays a crucial role in tobacco packaging thanks to its unique curing mechanism and color stability. Therefore, when testing UV ink for tobacco packaging, we not only need to focus on its basic physical and chemical properties but also take into account its performance during the printing process and the ultimate quality of the printed materials. Hence, we must employ scientific and reliable testing methods to ensure that the quality and performance of UV ink for tobacco packaging meet the stringent requirements of high-end tobacco packaging.

What are the common acrylic resins available on the market?

What are the common acrylic resins available on the market?

Acrylic resins are a general term for polymers derived from acrylic acid, methacrylic acid, and their derivatives. Acrylic resin coatings are thermoplastic or thermosetting resin coatings obtained by copolymerizing methyl methacrylate and styrene as the main components with other acrylates. During the manufacturing process, by carefully selecting different resin structures, formulating tailored compositions according to specific requirements, optimizing production processes, and employing various combinations of solvent ingredients, we can successfully synthesize a wide variety of acrylic resins with diverse properties and suitable for different application scenarios.

A Brief Discussion on the State and Indicators of Epoxy Resins

A Brief Discussion on the State and Indicators of Epoxy Resins

Epoxy resins refer to a general class of polymers whose molecules contain two or more epoxy groups. Under the action of specific chemical reagents, these epoxy groups can crosslink with each other, forming a robust, three-dimensional, network-like cured structure. Epoxy resins encompass not only oligomers containing epoxy groups but also low-molecular-weight compounds bearing epoxy groups. Epoxy resins exhibit a wide range of physical states—from liquid and viscous to solid—but their individual forms have little direct practical value on their own. It is only when epoxy resins react with curing agents to form insoluble and non-melting three-dimensional network polymers that their full performance characteristics are realized. Due to the chemical reactivity of the epoxy groups, they can be opened by a variety of compounds containing active hydrogen atoms, leading to curing and crosslinking into a network structure; thus, epoxy resins are thermosetting resins.

How to reduce infrared (IR) radiation generated by UV curing

How to reduce infrared (IR) radiation generated by UV curing

UV curing technology is an efficient material-curing process that has found widespread application, particularly in industries such as printing, coatings, and adhesives. In this process, ultraviolet (UV) light plays a crucial role: through its unique photochemical reactions, it enables resins and other materials to cure in an extremely short time. However, during UV curing, in addition to UV light, infrared radiation and heat are also generated. This phenomenon primarily stems from the fact that the light sources used in UV curing equipment, while emitting UV light, also emit a certain amount of infrared radiation. Infrared radiation is a type of electromagnetic wave with a wavelength longer than visible light but shorter than microwaves. A key characteristic of infrared radiation is its thermal effect—when absorbed by an object, it is converted into thermal energy, causing the object's temperature to rise. In UV curing equipment, infrared radiation is mainly emitted by the quartz bulb within the UV source. The quartz bulb is one of the core components of a UV lamp; its primary function is to protect the electrodes and luminous elements inside the lamp while allowing UV light to pass through. However, due to the material properties and structural design of the quartz bulb, it cannot completely block the emission of infrared radiation. Consequently, during UV curing, infrared radiation is emitted alongside UV light and irradiates the material being cured.

Hydrolytic UV adhesive for temporary bonding and protection

Hydrolytic UV adhesive for temporary bonding and protection

In the manufacturing processes of various industries, there are often occasions when temporary bonding is required. For example, in the electronics manufacturing sector, using hydrolyzable UV adhesives for temporary bonding during the assembly, encapsulation, and curing of electronic components can offer considerable convenience. In the field of optical glass processing, temporary bonding for CNC machining is also an indispensable part of the process technology. Hydrolyzable UV adhesives ensure that glass products remain securely fixed throughout the machining process and can be easily removed after completion by soaking them in hot water, leaving no residual adhesive behind. Moreover, hydrolyzable UV adhesives are widely used in industries such as medical devices and aerospace, providing a reliable solution for the temporary protection of both metal and glass materials.

What factors affect the performance of UV curing lamps?

What factors affect the performance of UV curing lamps?

The principle of UV curing is primarily based on the irradiation effect of ultraviolet (UV) light. By exposing liquid UV materials—such as coatings, inks, and adhesives—that contain photoinitiators to UV light within a specific wavelength range, the photoinitiators absorb UV energy and undergo a chemical reaction, thereby initiating the polymerization, crosslinking, and curing processes of polymeric materials like resins. Among these, UV lamps play a central role in UV curing technology. UV lamps, or ultraviolet lamps, emit UV light across various bands, including UVA, UVB, and UVC. In UV curing applications, UV lamps are mainly used to cure UV-curable resins. The curing performance of UV lamps is influenced by several key factors, including their spectral distribution, radiant intensity, and infrared radiation. These factors collectively determine the effectiveness and efficiency of UV lamps during the curing process.
