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 ...
One,Overview Paper-plastic composite can make the surface of paper printed matter more bright, smooth and color more bright and full of three-dimensional sense, but also play a role in moisture, anti-fouling, anti-counterfeiting, folding resistance, wear resistance and so on.It has been widely used and rapidly developed in printing and packaging industry at home and abroad. The market demand for p...
Composite film manufacturer there are bubbles and spots in the composite film, what is the cause? There are many factors in this kind of situation, and the actual situation needs to be analyzed in detail. The basic elements commonly used to produce bubbles and spots are: 1, environmental factors such as dust and suspended matter interference, which requires a good environmental health area environ...
Aluminized film glue is a composite material that binds aluminum film and other materials together by glue. It is usually used in paper packaging to prevent moisture, oxidation, heat insulation and pollution. First of all, the aluminized film glue can effectively prevent the paper from absorbing moisture and oxygen in the air, thereby maintaining the dryness and freshness of the product and extend...
1. The effect of membrane material There are dust adsorption, particle impurities, poor plasticization and other crystal points in the film. The moisture absorption on the film surface of the material and the precipitation of additives in the material will cause composite bubbles. The thickness of the film should be as uniform as possible, if the distribution is uneven, it is easy to cause the imb...
The transparency of composite film is very high, but in the composite processing of plastic film, the composite film often has problems such as insufficient transparency. So, what is the reason for affecting the transparency of the composite film? This article analyzes one by one for reference. Improper selection of adhesives: Such as the color of the adhesive itself is dark or the fluid...
"If there are small bubbles in the complex, opaque and foggy, it will not only affect the appearance quality, but also affect the peeling strength of the complex, reducing it, which is a very bad phenomenon." 1.The surface tension of the base film is too small, the infiltration is poor, the glue is not uniform, and the space without glue is empty and bubbles are generated. The solution is to use a...
Different processing methods will cause different fault manifestations, the following we mainly analyze the causes of paper thermit sealing delamination phenomenon under the gravure and solvent-free composite processing methods. The YBB paper aluminum-plastic composite film standard does not specify the composite strength index of the paper aluminum layer in the paper aluminum-plastic composite fi...
Many people see that a lot of Teflon coatings used in industry are green, especially when used in molds, let's talk about the reasons. The use of coating characteristics In extrusion or die casting products, generally dark, for example, rubber, silicone and so on, if the coating is made of dark, then whether the coating falls off is more difficult to see. Therefore, made of light color and with br...
Waterborne Polyurethane (WPU) is a polyurethane system using water as a solvent or dispersion medium. In recent years, with the increasingly strict environmental regulations and the improvement of people's environmental awareness, waterborne polyurethane, as an environmentally friendly material, has received extensive attention and research. First, the characteristics of waterborne polyuretha...
