Bond strength and deinking Bond strength is one of the most important indexes of glue properties. Bond strength refers to the amount of force required when the film and paper are stripped, and this index is often combined with the deinking effect. We first need to understand the principle and structure of paper-plastic composite. If you want to enhance the bonding force, you must consider the...
Anti -deformation power Anti -deformation capacity refers to a certain deformation after the composite product is affected by external forces, and this deformation will produce a certain amount of elasticity, especially the thin film. If the combination of composite is not enough to resist the elasticity of the return, foaming will occur, etc. Happening. There are many processes that produce defor...
Eight, filling The concept of filling is rarely mentioned in the application of laminating glue, but can never be ignored.The surface of the paper inevitably exists in some depression. When compounding, if the depression in the paper cannot be fully filled, it will also cause the weak. (Excellent filling effect) &nb...

Waterborne polyurethane: A new type of polyurethane system using water instead of organic solvent as dispersion medium, also known as water dispersed polyurethane, water polyurethane or water based polyurethane. Oily polyurethane: polyurethane system with organic solvent as dispersion medium, polyurethane system with thermoplastic linear structure. Distinguish by appearance Waterborne polyurethane...
Water based polyurethane is a kind of block copolymer containing soft segment and hard segment. The soft segment is composed of oligomer polyols, and the hard segment is composed of polyisocyanate and chain extender. It has excellent wear resistance, oil resistance, low temperature resistance, aging resistance and chemical resistance.At present, the water based polyurethane emulsion on the market ...
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 (PU) is a kind of organic polymeric compounds containing repeated carbamate group (NHCOO) in the main chain.Polyurethane polymer materials have the advantages of wear resistance, high temperature resistance, good adhesion, easy processing, low price, but some polyurethane water resistance, heat resistance is poor, need to be modified by specific methods, in order to achieve the purpos...
Water-based coating is an effective means to process the surface of printed matter, to improve the gloss and strength of the surface of printed matter, enhance the aesthetic effect, temperature resistance, water resistance, wear resistance, improve the grade of printed matter and commodity value. Therefore, to measure the quality of the coating, it is also necessary to examine the brightness, stre...
Polyurethane adhesive is a kind of high-grade adhesive, with excellent flexibility, impact resistance, chemical resistance, wear resistance, and the most important is its low temperature resistance. Because of its series of advantages, polyurethane adhesives are widely used in the following fields. 1. Carpentry industry With the improvement of people's awareness of environmental protection, the wo...
Polyurethane (polyurethanes, abbreviated PU) is a kind of polymer with -NHCOO-repeat structural unit as the main chain. Isocyanate (monomer) is polymerized with a hydroxyl compound.Due to the strong polarity of the carbamate group, insoluble in non-polar groups, with good oil resistance, toughness, wear resistance, aging resistance and adhesion. Materials suitable for a wide temperature range (-50...
Labels, as they are called in the printing industry, are mostly printed materials used to identify the relevant instructions of their products, and most of them come with glue on the back. But there are also some printing without glue, can also be called labels. Glue label is colloquially known as "sticker label". Label base material classification Substrate application surface material paper...
Water based adhesive for a more sustainable bond The market share of water-based adhesives is becoming increasingly large as development has shifted towards increasingly sustainable solutions that support health and safety and reduce environmental impact.Water-based adhesives are an excellent alternative to solvent-based systems because they do not contain any volatile organic compounds (VOC), are...
Adhesive label is a representative pressure sensitive adhesive product which coexists with adhesive tape for packaging. Its wide range of uses, such as: food, cosmetics, drugs and other use of senior beautiful label; Quality marking labels for fiber products, electronic machines, daily necessities, etc.; A price tag used in a supermarket or grocery store; Computer tags for schools, hospitals and o...
Self-adhesive labels are ubiquitous in our daily life, and are necessary consumables for many manufacturers. However, the warping Angle of self-adhesive labels has been troubling many manufacturers. A small warping Angle will directly affect the beauty of the products, leading to their own products are not favored from the visual point of view. So, why will self-adhesive warping Angle? How to deal...
