Classification and quality requirements of BOPP sealing tape (including ordinary sealing tape, printing tape, high-viscosity antifreeze tape):The series of products mainly to polypropylene film, special polypropylene film, acrylic and water-based acrylic plastic as raw materials and has the characteristics of posting smooth. It is suitable for general packaging and fixed and packaging an...
Material property (pu for short) is divided into: Pouring polyurethane elastomer (CPU for short) is one of the most widely used polyurethane elastomers with the largest yield. Thermoplastic polyurethane elastomer (TPU) -- thermoplastic polyurethane elastomer accounts for about 25% of the total amount of polyurethane.Mixed polyurethane elastomer (MPU) - accounts for about 10% of the total amount of...
Plasticizer is widely used in industrial production of polymer materials auxiliaries, also known as plasticizers. All substances added to polymer materials that increase polymer plasticity are called plasticizers. The use of plasticizer can improve the properties of polymer materials, reduce production costs and improve production efficiency. is a class of important chem...
The soluble carrier of water-based plastic composite ink is water. Because water is used as the soluble carrier, water-based plastic composite ink has significant environmental protection and safety characteristics. It is safe, non-toxic, non-flammable and non-explosive, and almost no volatile organic gas is generated. No pollution to the atmosphere because of water-based plastic composite ink wat...
After toning water-based plastic composite ink is used, there is often error with the standard color, which is difficult to completely avoid the problem, can only be reduced to a low limit. Different printing ink factory use of the same part of the printing machine, different printing machine mesh mesh line number Angle has a big difference, which makes the same ink, in different printing methods ...
Plastic film as the object of packaging printing, many kinds, and the use of printing also involves many aspects, so the variety of this kind of ink is extremely wide.In particular, this ink shall have the characteristics of fastness to adhesion printing effect processing tolerance and other requirements.The surface of plastic film is smooth, and the ink can not be permeated, so it must be printed...
Self-adhesive label Is also called self-adhesive label material. It is a composite material made of paper film or other special materials, coated with adhesive on the back, and coated with silicon protective paper as the base paper.And after printing die - cutting and other processing into finished labels. Self-adhesive materials are usually printed and processed on the label linkage machine. The ...
Vacuum suction plastic is a kind of waterborne polyurethane adhesive, because it needs vacuum suction plastic machine to vacuum suction plastic so it is called vacuum suction plastic.It is widely used in the vacuum blister thermal composite of visible parts, such as polyvinyl chloride (PVC) and other soft materials and density board, particle board, wood and other vacuum blister molding, main...
① BOPP/VMCPP The composite structure is mainly used in light food packaging such as instant noodles, egg yolk pie and snow cake. The composite structure is the most suitable for one component water-based adhesive. Compared with solvent-based polyurethane adhesive, the single group of water-dispensing adhesive has less ink transfer phenomenon, high initial adhesion, no need for curing, and can be d...
Polyurethane is the short form of polyurethane (PU). It is a block polymer formed by addition polymerization. It is a polymer compound with flexible and elastic polyether or polyester as soft segment and rigid and hard carbamate as hard segment. It contains a considerable number of ammonia ester bonds. Waterborne polyurethane has been successfully applied in the textile printing and dyeing industr...
①BOPP / VMCPP The composite structure is mainly used in the field of light food packaging such as instant noodles, egg yolk pie and snow cake. The composite structure is most suitable for one-component aqueous adhesives. Compared with solvent-based polyurethane adhesive, single component water glue less ink transfer phenomenon, and the initial adhesion is high, without aging, can be directly cut b...
As a professional manufacturerof label and package printing coating industry, Anhui Sinograce Chemical Co., Ltd took part in this LABELEXPO Europe-2023 exhibition.he exhibition focused on showing the company's coatings in the field of coatings, including water-based label adhesive and water based paper adhesive,top and primers coating, Other Adhesive,coating additives,film etc. In the four da...
Viscosity is an important index of ink rheology.In printing, a certain viscosity is the main condition to ensure the normal transfer and uniform transfer of ink.It is related to whether the printing process can proceed smoothly, and directly affects the uniformity, clarity and gloss of the imprinting ink, and also relates to the viscosity, fluidity, yield value, thixotropy, drawing and other prope...
After the ink is stored for a period of time, the upper part of the ink appears thin in the container, the viscosity is small, and the color and concentration are relatively poor; The lower part is thick, the viscosity is large, and the color and concentration are also relatively good. Intaglio printing inks are thin and have a small viscosity, because the pigment is poorly dispersed in the connec...
The main reason for water-based ink drying 1.Water-based ink: water-based carton ink, non-woven ink, paper towels, paper cups and paper bags and other packaging printing; 2.Water-based polishing oil series: water-based polishing oil, polishing oil, high gloss, wear-resistant, matte, waterproof, antifreeze and other environmental protection water-based products. Water-based ink drying is mainly cau...
The main function of the film surface coating treatment agent is to enhance the comprehensive performance of the film through chemical or physical modification. The specific functions can be summarized as follows: 1.Enhance surface adhesion Improve the adhesion of ink/adhesive: By increasing the surface energy of the film or introducing polar groups, make the ink, coating or adhesive more lik...
