The development history and technology of Symphony Crystal Label

In the labeling of beer, the label of traditional wet adhesive tape has long dominated the world, even though it still occupies a large market. Traditionally, the cost of wet labels on beer labels is relatively low, but the labels will come off during the process of use, and the package design cannot reflect the brilliance of the beer. The emergence of ultra-transparent film stickers exactly meets the market requirements. A clear, transparent sticker on transparent glass or PET bottles produces a crystal-clear, label-free effect. The high quality printed image on the transparent label will be a high grade. fresh. The clear and youthful image is passed on to consumers, giving them the desire to purchase in real time. This is the result of high-end consumer goods that have benefited from eye-catching label decoration to promote sales.

Compared with the wet adhesive label, the transparent label has the following unique advantages: high transparent material, no label appearance; clean and tidy, performance of high quality; moisture-proof and water-resistant, long-term ice-cold; suitable for efficient automatic labeling; meet a variety of printing processes and Innovation requirements.

The Symphony crystal label is made of thin-film laser materials. According to the needs of customers, it combines printing and material light column effects to create a unique metal texture and a brand new visual experience. Due to the exceptionally special effect of displaying colorful and colorful colors under light illumination, it can fully reflect the crystal clear visual effects of bottled beer. With the use of laser tags, Tsingtao Brewery successfully created a new level of product brand image, improved product quality, shaped the product's differentiated packaging, and a good anti-counterfeiting effect also played a role in protecting corporate brand.

At present, there are two kinds of film label applications, one is a self-adhesive, and the other is a cold glue label.

Like ordinary stickers, the Crystal Beer sticker is a three-layer structure. The outer layer is a transparent film that is bonded to the backing paper through a transparent layer of glue. According to the application field and specific requirements, different materials can be used for each layer.

The first is surface material, usually 50 to 60 μm polypropylene or polyolefin film, which has excellent transparency. Because it has good stiffness after biaxial stretching in the production process, it is suitable for high-speed labeling and can satisfy smooth out. The standard requirements, with a rigid bottle is very fit. The text on the label can use letterpress. Flexible version. Gravure. Silk screen printing and other methods, and hot stamping. Excellent hot silver performance.

Followed by adhesives. The glue can be divided into emulsion or solvent-based glue. Emulsion-based glues are environmentally friendly glues. Coatings are cheaper than solvent-based glues, and there is no risk of penetrating the bottle into the beverage like solvent-based particles. However, if the pre-labeled bottle is to enter the sterilizer after filling, the emulsion-based glue is not suitable. Because the emulsion-based glue whitens during the sterilization process, the transparent effect is destroyed. In these cases, a solvent-based glue is required. To match high transparent surface materials, the glue used needs to have excellent transparency; in addition, since people often drink iced or soaked in cold water when drinking beer, it is necessary to maintain the transparent properties of the adhesive in this environment. Discoloration, at the same time, the label can not play off. Even with water, the adhesive remains sticky and does not whiten. As the main application is for disposable bottles, permanent adhesives are generally used.

Finally, the backing paper, PET or PP film can be used as a carrier material. The tensile strength of the paper base paper is lower than that of the film base paper, and the PET base paper is the most flat. The strongest pull force; PET film can be better fixed on the label wheel than the corresponding thickness of PP film, and has a better toughness, to meet the high-speed labeling requirements. The flatness of the backing paper directly affects the flatness of the glue coating, which also affects the transparency of the label.

Here also need to emphasize the coating requirements of adhesive materials. Has excellent bottom paper. After the adhesives and facestocks, the coating process is also the key to determining whether the final quality of the adhesive is excellent. The more uniform the coating, the better the flatness of the glue, and the better the overall transparency of the label.
