BOPP film tape introduction --

Tape development history--

four. Development of technology and efficiency products

However, in the face of the future, although it is impossible to comprehensively predict the development status of the tape industry or variety, the preconditions and planning blueprints are tightly bundled in the standard application specification of the processing application and adhesive arrangement combined with the medium. For example, new technology products automotive insulation paper (wear, light, sun, heat insulation), PVB color glass tape (color decoration, heat insulation, noise, earthquake blasting), environmentally friendly waterproof coating film (Computer drawing water ink compatible, waterproof and wearable), highway refraction film glass microbead composite tape (eye-catching refraction, temperature resistance, cold resistance, freeze resistance, acid resistance, anti-aging), digital camera waterproof high gloss photo paper (computer drawing water The development, processing and manufacturing of products such as ink compatibility, waterproof and abrasion resistance, high resolution, high reductiveness and long shelf life are all applications of media surface treatment technology. On the other hand, such as; aerospace equipment without media double-sided tape (high temperature resistant film), medical conductive tape (heart pulse electric shock and medical detector fixed), printed circuit board composite tape (high temperature, impact resistance), car Interior decorative panel (high temperature resistance, buffer safety, aesthetics), road marking tape (eye-catching, temperature-resistant, cold-resistant, freeze-resistant, acid-resistant, anti-aging), correction tape (shading, writing, ink absorption) (Sex), anti-counterfeiting and brittle tape (easy brittle, anti-counterfeiting, printing, shielding) and other products are subject to the technical transformation of the adhesive. However, if the basic structure of the two types of products is carefully summarized, the technical results formed on the basis of the adhesive application are only the technical process differences between the application process and the treatment, and the main surface function of the medium surface treatment or the adhesive is distinguished. In fact, most of the technical applications of various types of tape products are based on the application and function of adhesives.

Advances in coating technology
     Advances in coating technology require the continuous development of pigments, adhesives and auxiliaries, and coating auxiliaries are becoming more and more important.
     As the solids content increases, the viscoelastic properties of the coating become more and more important. The interaction between the various components in the coating results in the structuring of the wet coating and exhibits significant viscoelastic characteristics. It would be beneficial if such a structure of the coating could be effectively broken under shear and recovered quickly after metering. On the one hand, it exhibits good runningability, on the other hand, it has less migration of coating adhesive and good coating coverage. However, at very high solids, the viscoelastic structure does not eliminate to the desired level. As a result, problems that may occur with the above-described blade coating and metering size press coating are produced.
With theoretical breakthroughs and technological breakthroughs, WRRM, which can significantly reduce the viscoelastic properties of coatings, has begun to emerge. The addition of this WRRM not only allows the          Coating to exhibit lower viscoelastic characteristics, but also helps to quickly eliminate viscoelastic properties under shear and renders the coating viscoplastic at high shear rates. Such a coating can achieve better blade and metering size press coating runability, and can increase the solids content by 2 to 3%, while the high shear viscosity is the same or lower.
     Spray coating and curtain coating require a new coating aid to achieve good runnability. For example, a wetting agent is required in the coating to allow the spray coated coating to drip and stabilize the curtain coated coating curtain. More importantly, spray coating requires a low coating viscosity, and curtain coating requires a suitable coating elongation viscosity and other properties may also require suitable additives to match.
     In addition, coating auxiliaries also show a trend of versatility. Rheology and water retention modifiers have some of the functions of lubricants, and even some companies claim to function as water repellents; new lubricants show many of the characteristics of rheology modifiers.
