Sixteen common types of self-adhesive labels This paper introduces sixteen types of self-adhesive labels commonly seen in daily life. The specific types of self-adhesive labels are as follows： 1. Press smooth writing paper and offset paper labels Multi-purpose label paper for information labels, bar code printing labels, especially suitable for high speed laser printing, also suitable fo...
Label is used to show the relevant instructions of the product of the printed matter, some are on the back of the glue, but there are some printed matter is not with glue, glue label is known as "self-adhesive label". Self-adhesive label is a kind of material, also called self-adhesive material. It is a composite material made of paper, film or other special materials, coated with adhesive on...
Hot melt adhesive (English name: HotGlue) is a kind of plastic adhesive, in a certain temperature range, its physical state changes with the change of temperature, but the chemical properties remain the same, its non-toxic and tasteless, belongs to environmental protection chemical products.Because the product itself is solid, easy to package, transport, storage, no solvent, no pollution, non-toxi...
The relationship between the index of laminating glue and common problems I. Viscosity Viscosity is the internal friction of the liquid, and colloquially, the thin consistency of the glue. The viscosity of the glue does not indicate the bonding performance of the glue, in other words, the thicker the glue is, the better the performance is. The viscosity can be adjusted within a cert...
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...
New environmental protection water-based laminated adhesive 1.This new environmental protection water-based laminated adhesive does not contain any organic solvent, has passed the international certification SGS, so it is non-toxic, there is no flammable, explosive danger, please rest assured that the manufacturers in the industry use. 2.Water-based laminated adhesive does not contain toxic heavy ...
Water-based dry coated adhesive water based bopp film lamination adhesive glue Product Model SA-228 Packing Plastic bucket (50KG/ bucket) or paper bucket Main Application Suitable for gold and silver card paper or ordinary paper and BOPP, PET composite Basic parameters 1 Main material Acrylic emulsion 2 Appearance Opalescent with blue light 3 Viscosity Coat 4 cups≥18S±3 4 PH 6.5-7.5 6 Storage life...
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...
