(1) Laser Holographic Paper Can be divided into two kinds of film stickers and plain paper. The film sticker is made by laminating different types of paper with a laser holographic PET or OPP film. The conformed paperboard is not only more flexible but also less prone to tearing, and the film surface can be waterproof. Laser holographic pure paper directly prints the laser hologram on the paper through advanced imprinting technology. Its greatest feature is environmental protection. Whether it is a laser holographic film sticker or plain paper, it is suitable for general ink or UV ink printing. In addition to being an excellent paper box, book magazine cover or poster material, it has also been used for gift wrap, chewing gum, soap and other packaging. In addition, the label is another major area of ​​application of laser holographic paper. In order to meet the needs of this market, laser holographic paper has introduced laser holographic wet strength paper. Although it is also pure paper, it will not suffer from low temperature or humid climate. Destruction, and can be made into automatic washing labels, so it is particularly suitable for use on recycled wine bottles and refrigerated food labels. (2) Laser Holographic Gold Foil Laser holographic hot stamping foil is holographic laser processing of thin foils with hot stamping function to form two-dimensional, three-dimensional, lattice, spiral, synthetic holographic and other images, with high-gloss, colorful and changeable colors, overcome the The common bronzing technology has the defects of monotonous form, low quality, and lack of anti-counterfeiting effects. The laser holographic hot stamping foil has ordinary hot stamping foil and transparent laser holographic stamping foil. In the laser holographic stamping foil, different holographic effects can be combined with each other, and at the same time, dual channels, partial aluminum plating, color separation effects, micro engraving can also be added. Various anti-counterfeiting elements, such as hidden information, are used in the surface finishing of printed products and papers to achieve their unique copyright protection with effective high-level anti-counterfeiting measures. In addition, the laser holographic hot stamping foil dyed layer is a grating, and the color or the image is not a pigment, but a holographic pattern formed by the microscopic pits (gratings) on the surface of the transfer layer after the laser beam is applied. The generation of the hologram pattern is quite complicated and has a very good Anti-counterfeiting effect, the scope of gold foil foil application include ticket price, tobacco and alcohol, medicine, fashion, clocks, computer software and other packaging, special surface decoration after label printing, etc. In addition, there are laser holographic scratch bronzing, suitable for Password protection for lotteries, telephone cards, etc., as well as anti-counterfeiting and decorating effects. (3) Laser Holographic Cold Foil It is the use of printing and lamination technology, the laser holographic foil is transferred to the substrate. It breaks the traditional process of traditional bronzing relying on hot-press transfer of gold foil. The use of a new technology, cold-pressing technology, to transfer gold foil not only solves the difficult-to-solve process problems in hot-foil printing, but also avoids the production of metal plates. The pollution caused to the environment during the process can also save a lot of energy. Cold foil has the advantages of fast printing speed, short production cycle, wide application of materials, high printing precision, good anti-counterfeiting effect, cost saving, full use of existing equipment, high production efficiency, and compliance with environmental protection printing requirements. It has been printed in Europe and America in recent years. The latest scientific and technological achievements in the industry. The laser holographic cold foil can also be transparent and cold hot, achieving the security and brand identity. (4) Laser holographic aluminum foil It is to add the laser holographic image on the ordinary aluminum foil so as to improve the anti-counterfeiting function and the appearance effect of the packaging product. With good processing adaptability, it is very suitable for mechanized production. The main application object of aluminum foil is pharmaceutical packaging. Because it has excellent light-shielding, moisture-proof, gas-barrier, and taste-protecting properties, it plays an almost absolute role in barrier protection of light, gas, moisture, and taste of drugs. The shelf life of the drug. However, general aluminum foil has no anti-counterfeiting function, and laser holographic aluminum foil has more laser holographic processing technology, so that a counterfeiter cannot easily obtain or duplicate the same material, and therefore, the anti-counterfeiting performance of the medicine can be improved.
Shampoos contain a variety of ingredients that combine to cleanse the scalp and hair. Often the most effective ingredient in shampoo is a surfactant, which cleans hair and scalp. When shampoo is mixed with water, it creates a lather, though the amount of lather isn't a good indicator of cleaning power.
When consumers choose shampoo, they should first understand their hair characteristics, oily, neutral or dry hair, and then choose the right shampoo; Secondly, to choose the right brand for their own, different brands of shampoo formula will be different.
The causes of dirty hair include the residue of dust and styling agent, and the other point is the oil and sweat secreted by the scalp. Therefore, it is recommended to choose shampoo with moderate cleaning power, careful foam, and small irritation.
If you use a shampoo that is too strong, your hair will be too dry or prone to dandruff because it will lose too much of the necessary fat. This is often heard that washing hair will lose hair, easy to let the hair become dry and have dandruff reason.
