The OPP,PET film substrate | is an environmentally friendly coating using advanced material technology, which can significantly enhance the adhesion of EVA on difficult PET substrates and improve the product quality of PE card film. Card film, also known as plastic film, is a plastic film product coated with adhesive and OPP and PET as the substrate, which is widely used in the storage and protection of identity cards, driving licenses, and other flake items. After plastic sealing, it has the advantages of waterproof, anti-smear, anti-moth, anti-mildew, anti-corrosion, easy to clean, clear and transparent, neat and beautiful. However, the surface polarity of OPP and PET materials is low, and the adhesive is a polar material, when the two are combined, the adhesion is not ideal. For a long time, in the production of OPP and PET card film, how to solve the adhesion of EVA on the plastic film substrate such as OPP and PET has been a technical problem. The OPP and PET film substrate | of Sinograce Chemical Company has been carefully designed with special functional groups, which can effectively combine with the polarity group after corona treatment on the surface of PP and PET films to produce a coating with high adhesive force, which plays a good role in the foundation of EVA on OPP and PET film substrates. The OPP and PET coating agent | of Sinograce Chemical Company successfully solves the problem that the surface of PP, PE and PET plastic film is difficult to adhere, and provides an efficient solution for the development of high quality and environmental protection of card film products. Product feature Effectively improve the adhesion of pressure sensitive adhesives and OPP and PET substrates: Because OPP and PET plastic films are weakly polar materials, and EVA adhesives are polar materials, EVA adhesives are difficult to attach directly to the surface of OPP and PET plastic films. The OPP, PET film primer | adhesive of Sinograce Chemical Co., Ltd. has special functional groups, which can effectively bond with the polar groups treated by corona on the surface of OPP and PET films to produce a coating with high bonding force, which plays a good role in laying EVA adhesive on the substrate of PET tape. Prevent pressure sensitive adhesive from penetrating into the substrate and improve the coating quality: The OPP, PET coating agent | of Sinograce Chemical Company adopts self-crosslinked resin to provide a physical barrier between the body film and the adhesive, which can prevent the low molecular weight substances in EVA adhesive from penetrating into the film, which is conducive to the long-term stability of the substrate film. Outstanding high temperature resistance: Sinograce Chemical Company's OPP, PET card film substrate | high temperature performance is excellent, will not yellow at high temperature, affect the quality of plastic sealing products. Fast drying speed to meet the needs of production line: Sinograce Chemical Company's OPP, PET ...

PET label primer Cost-effectively improve the printability of PET labels Excellent adhesion with PET label substrate Good affinity with all kinds of ink Good weather resistance, no yellowing Easy to use, safe and environmentally friendly PET label primer is a water-based coating designed to improve the printability of PET label paper with advanced material technology and formulation technology. Due to the excellent dielectric properties of PET, and good anti-fouling, anti-scratch, high temperature resistance and other properties, PET labels are widely used in food packaging, electronic appliances, medical and other fields. However, for a long time, the adhesion of ink on the surface of PET substrate has been a technical problem. The PET label base coating agent of sinograce Chemical Company has been carefully designed and has special functional groups, which can be effectively combined with the polar groups on the PET surface to quickly form a transparent film with high gloss and excellent adsorption for all kinds of inks, and improve the printability of PET substrates. On the basis of high adhesion, PET label base coating has good weather resistance and does not yellow. The PET label base coating of Sinograce Chemical Company has successfully solved the problem of printability of PET surface, providing an efficient solution for the printing of plastic label surfaces on PET substrates. Product feature Cost-effectively improve the printability of PET substrates: Since PET is a weakly polar material, printing directly on the PET surface will cause the printability of the ink to decrease. PET label primer successfully improves the printability of the ink on the PET surface by undercoating, without special equipment or processes. Excellent adhesion with PET substrate: The polymer structure of PET label primer has special functional groups, which help the molecular chain flow and wettability on the PET substrate surface, so that the coating and the substrate molecules are in close contact to achieve high adhesion. It has excellent absorbability for all kinds of inks: PET label base coating is carefully prepared, and the ink has a certain penetration effect on the PET label base coating, which improves the wetting ability of PET to UV ink, increases the firmness of UV ink, and eliminates the insufficient adhesion of UV ink on the PET substrate. Good weather resistance, no yellowing: PET label primer has excellent weather resistance and can be widely used in various occasions. Easy to use, safe and environmental protection: PET label base coating is a single-component product with water as a dispersing medium, does not contain heavy metals, environmental protection, non-toxic, no combustion and explosion risk, and can meet the environmental protection requirements of the European Union.

The rheological properties of the ink include the viscosity, adhesion, yield value, thixotropy, fluidity and fluidity, and transferability of the ink. In the printing work, the rheology of the ink has an important impact on the quality of the printed product. The following are to talk about the impact of these rheological properties on the printing quality of ink. First, viscosity. Viscosity is a measure of the ability to hinder the relative movement of molecules caused by the mutual attraction of fluid molecules, which shows a property of preventing flow in the fluid and the degree of resistance to flow. The motion resistance caused by the mutual attraction between fluid molecules in the process of fluid flow is called internal friction. Viscosity is an important indicator of ink rheology, in the printing process of a certain viscosity is to ensure that the ink support transfer and uniform transfer of the main conditions, it is related to the printing process can proceed smoothly, and directly affect the uniformity of ink, clarity and gloss. Improper control of ink viscosity in printing will bring a variety of failures to printing, as listed below. 1.When the viscosity of the ink is too large, the drawing property is strong, during the ink transfer process, the wire head is too long when it splits between the ink rollers, and the broken end of the wire head is easy to form the ink flying into the air, forming the flying ink phenomenon in printing, and the flying ink phenomenon is more obvious in high-speed printing. 2.the viscosity of the ink is too large, it is easy to cause the depowder of the paper, drawing or delamination stripping phenomenon. This phenomenon is particularly obvious when the structure of the printing paper is loose and the surface strength is not high. 3, when the ink is transferred and transferred between the ink rollers, the viscosity is too large to make the ink transfer difficult. Excessive ink viscosity will lead to uneven distribution of ink, insufficient ink transferred to the plate or printed matter, uneven ink, and the phenomenon of bare print graphic base. Other effects of excessive viscosity on the printing process, such as the increase in the amount of ink, the printing ink layer is too thick, the drying speed is slow, and the back of the printing matter is easy to stain or adhere; In flat paper printing, it is also easy to produce the phenomenon that the paper is sucked into the ink roller. 5.the viscosity of the ink is too small, its fluidity increases, and it is easy to produce ink emulsification in the offset printing, resulting in dirty prints; The ink with too small viscosity is easy to produce spreading phenomenon on the paper, resulting in a large imprint area, a decline in clarity, and reduce the firmness of the combination of the imprinted dry conjunctiva and the substrate surface and the gloss of the imprint. 6.The viscosity of the ink is too small, often can not drive the ink particles in the larger p...
