After the composite product has been cured at a certain temperature and time, the interlayer peeling composite film adhesive layer still has a certain viscosity, that is, after the composite film peeling, the two-layer film will be re-glued together by hand, and the severe drying of the composite film adhesive layer will directly affect the peeling strength of the composite film, while the slight ...
I.Overview: Refilm process is widely used in all kinds of packaging, small to medicine box, artifact box, large to outer packing boxes and various product packaging.The current recoating technology includes precoating, dry recoating and wet recoating.Wet composite uses water-soluble adhesive cold paste process. Dry composite traditional composite film process is to apply solvent-based adhesive dir...
Water-based adhesive with high polymer, water-soluble resin as the main raw materials, water as the solvent, odor is small, environmental protection and non-toxic. With the continuous improvement of people's environmental awareness, water-based adhesives have become the mainstream of the market in recent years. In practical application, some packaging and printing manufacturers do not know enough ...
ater Based Polyurethane Peelable Protective Coating PU-207 is a protective resin made of waterborne polyurethane base material with advanced technology. The water-based peeling paint made from this is bright in color, fine and uniform in particle size, coating on the surface of automobiles, furniture, electrical appliances and other objects as a protective coating, has good protecti...
1.The role of acrylic resins in photocured inks.Acrylic resin is widely used in the manufacture of photocuring inks because of its unsaturated property and polymerization reaction under the action of ultraviolet light.It and other substances, such as polyether, carbamate, polyester, epoxy resin, modified epoxy resin, poly caprolactam copolymer, can be used as a photocuring ink resin component. 2.T...
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...
The addition of wetting dispersant has obvious effect on the foam of some water-based ink.For example, polyacrylic acid wetting dispersants foam more than other types of wetting dispersants.Generally speaking, wetting dispersant foam with low dispersion capacity is also less. If diisobutyl sulfonate is based on disate, there is little foam at its content of 0.1-0.25%. The use of thickeners will ma...
Environmental protection pressure has prompted some traditional solvent-based products to gradually withdraw from the market and replace them with water-based, high solid content, powder products, etc.Waterborne polyurethane, as an important member of waterborne products, is facing unprecedented development opportunities with its unique excellent properties.In addition to the leather industry, it ...
With the continuous improvement of people's demand for life, glue and adhesive products are also advancing with The Times and constantly upgrading to meet people's needs. The emergence of removable glue greatly satisfies this phenomenon, so what is removable glue? What are the characteristics of removable glue? Removable adhesive is a new type of environmentally friendly synthetic material, the ap...
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...
PET protective film material is transparent colorless, the surface after hardening treatment, the general PET protective film material according to the origin of different, the surface hardening value between 3H-4H, the better the surface hardening, the stronger the wear resistance. Light transmittance is also the main property of PET protective film materials, the general light transmittance is m...
Composition of adhesive Adhesives are adhesives that can bond two objects together, referred to as glue. There are different types of adhesives according to different divisions, the use of adhesives is also quite extensive, and now it has been filled in our lives, for adhesives, do you know how it is composed? How adhesives are composed: Synthetic adhesive Synthetic adhesive is composed of main ag...
Water-based pressure-sensitive adhesive is a type of adhesive that uses water as a solvent and is pressure-sensitive, that is, it can adhere quickly to the surface when slight pressure is applied. Due to its environmental protection, non-toxic, cost-effective, adjustable viscosity and other advantages, it has gradually become the mainstream product in the pressure sensitive adhesive market. Accord...
With the development of the market economy, the demand for flexible packaging in various industries is also rising year by year. The development of flexible packaging materials and processing technology continue to improve, flexible packaging in many areas is playing an increasingly important role, so what are the composite ways of flexible packaging? This article briefly describes five composite ...
