• The Value Of The BOPP Label

  Label updates: Sooner or later, the BOPP labels of brand-name products will become obsolete, so it needs to be revised after a period of time. For example, the label of ivory soap has changed the font size and shape 18 times since the 1890s. OrangeCrush beverages have significantly revised their labels due to the use of fresh fruit labels by competing brands. The new design symbolizes freshness and has stronger and deeper colors. Legal restrictions on product labels: For a long time, the law has restricted labels. Poor labels can cause misunderstanding to customers, or fail to describe important components of products, or provide adequate safety warnings. The US federal and state governments have targeted labeling legislation, the most important of which is the Fair Packaging and Labeling Act of 1966. In recent years, the label decision has been affected by unit price (indicating the price of each standard unit), unsealing period (indicating the shelf life of the product), and nutrition labeling (indicating the nutritional value of the product). Before launching a new product, a seller must determine whether its label contains all the necessary information.

  Film cosmetics labels can be divided into two categories: ordinary film labels and in-film labels: Ordinary film labels are generally PE, BOPP film stickers (with glue on the back), which can be flexo, embossed, screen printed, offset printed. The surface is protected by waterproof varnish; it can be pasted with a labeling machine,in mould labels: The material and printing are the same as above, but there is no glue. It is placed on the mold wall when the bottle is blown. After the bottle is blown, the label is directly embedded into the surface of the bottle and integrated. At present, the special technology and processing of such labels include foaming inks, which can touch the three-dimensional effect of the text, cold or hot stamping, and the hot stamping part has a metallic texture. That's it.

  Product labeling decision is a kind of product decision, it is important based on the consideration of product labeling. Product labels should include product logos, manufacturing dates, product descriptions, and graphic designs. Labels must not only differentiate between products, but also have attractive patterns and fonts to promote sales. The need for product labels: The manufacturer must design a label for the product. It may be just a simple label attached to the product, or it may be a well-designed pattern that integrates with the product packaging. Some in mould labels only indicate the brand name, and some are quite rich in content. Although manufacturers prefer simple labels, sometimes the law requires the labels to provide more information. Features of product tags: Tags have several functions, so manufacturers have to decide what features their tags should have. The minimum function of a label is to identify a product or brand, such as the Sunkist stamp on a Shangi Citrus. Labels can also be used to distinguish product grades, such as A, B, and C labels on canned peaches. In addition, the label can describe several pieces of product-related information, including the manufacturer of the product, the place of manufacture, the date of manufacture, content, and how to use it. Finally, labels can promote products with their attractive graphics. Product label updates: Sooner or later, the labels of brand-name products will become obsolete, so it needs to be revised after a period of time. For example, the label of ivory soap has changed the font size and shape 18 times since the 1890s. OrangeCrush beverages have significantly revised their labels due to the use of fresh fruit labels on competing brands. The new design symbolizes freshness and has stronger and deeper colors.

  Label printing covers several major printing methods, in the plate making stage. Depending on the nature of the product, different printing methods are selected. For different printing methods, the platemaking process is also different. This article briefly introduces the flexible plate making process as an example. The process of flexographic plate-making is as follows: manuscript-film (exposed film) -exposure-rinsing-drying-post-processing. 1. Original. The manuscript design suitable for flexible printing should have the following characteristics: many color numbers. However, there are few in mould labels; it is not required to reproduce particularly small details; the network cable is not too high, but it can obtain color printing effects; it can be used for packaging processing online. 2. Film (overcast). It meets the needs of plate making, with clear graphics and accurate size specifications; using frosted film, the density of the four corners of the film must be consistent; using the film orthography; using a transmission density meter to measure, the white density is less than 0.06; 3． Exposure includes back exposure and main exposure. ① Back exposure. The support film of the photosensitive resin plate faces upward and the protective film faces down in the exposure drawer to receive exposure. Ultraviolet light passes through the support film to cure the photosensitive adhesive layer. In order to establish a stable base, the depth of the washing plate can also be controlled, and the binding force between the supporting film and the photosensitive resin layer can be strengthened. The back exposure time is determined by the required substrate thickness. ② The main exposure. Also known as front exposure, the support plate of the photosensitive resin plate faces down and the protective film faces up. Tile in the exposure drawer. Tear off the protective film one at a time, and then affix the film film surface to the photosensitive resin plate. Cover the vacuum film flat female 1 with high yield * female A inspection method cover the film (the non-medicine film is evacuated to make the film and the photosensitive resin layer adhere tightly. Ultraviolet light passes through the vacuum film and the film transparent part to make the plate light sensitive Partial polymerization curing. The length of the main exposure time is determined by the version of the plate and the intensity of the light source. If the exposure time is too short, the slope of the graphic will be too straight, the lines will be bent, and the small characters and small dots will be washed away. The handwriting is blurred. If there are large, small, thick, and thin lines on the same printing plate. Depending on the situation, a black film can be used to cover the exposure. Small portions will not be lost due to processing to ensure the quality of the printing plate. 4． rinse. Wash and dissolve the non-photosensitive parts to retain the photopolymerized relief. The length of the plate washing time is determined by the thickness of the printing plate and the depth of the print. If the plate washing time is too short, unsensitized resin will be left on the plate and affect the plate making depth. If the plate washing time is too long, the plate will swell, causing the fine parts to deform or Fall off. 5. drying. Remove the plate washing solvent to restore the plate to its original size and thickness. The baking temperature is between 50-60 ° C. The baking time is determined by the thickness of the plate and the length of the plate washing time. Generally, the thick plate is two hours and the thin plate is one hour. The baking time is too long, and the baking temperature is too high, which will make the printing plate brittle and affect the printing life. If the baking temperature is too low, the drying time will be prolonged. If the baking time is too short, the phenomenon of rotten printing will occur during printing. 6. Post-processing. Detackification and post-exposure. The photosensitive resin is completely hardened (polymerized) to achieve the desired hardness index, and the viscosity of the printing plate is eliminated to facilitate ink transfer. The post-treatment time is obtained by testing, and the purpose is not to crack or stick.
