The application of pressure-sensitive film

the author of this paper describes the method of attracting retail customers in the beverage industry as "screaming for attention", and expounds the current situation that businesses increasingly emphasize the use of packaging design to affect consumers' purchase desire

more and more food and beverage industries stimulate consumption by attracting customers' attention. With the increasing number of beverages and specialty foods in the new era, consumer goods manufacturers need to obtain the shelf availability of products through high-quality and low-cost packaging images, so as to create brand awareness

in this competitive era, eye-catching packaging decoration is the best opportunity to leave a strong first impression on customers. Research shows that about 70% of customers make purchase decisions out of impulse. This has stimulated manufacturers to influence consumers' choices by emphasizing packaging design, which has formed a packaging market of billions of dollars, and is developing at an unprecedented annual growth rate

pressure sensitive film (self-adhesive film) is the best choice for food and beverage packaging materials (the upper and lower surfaces of the sample are bonded with 100x100mm metal plates respectively with adhesive). It is a cheap material that can be printed by various technologies. Film is an ideal choice for designers to create multifunctional and durable trademarks. It has a unique appearance that other packaging and decoration methods do not have. In particular, polyolefin film can enable manufacturers to produce high-grade "non trademark appearance" images, can withstand the wear and tear of the filling production line, can also withstand the extreme temperature of heating sterilization and freezer refrigeration, and reduce the time limit when storing on the shelf

film and aesthetics

the idiom "what you feel is real" is the most suitable for packaging decorations. The pictures pasted on the outside of the packaging container represent the quality of the product. Moreover, the trademark must be kept intact during the whole service life of the product, and it should have the same brand-new appearance from the first time the product is put on the market until the customer throws away the empty product packaging container

pressure sensitive film has a more beautiful appearance than other similar technologies, because it can be printed through a variety of different technologies, supporting a variety of printing methods from monochrome printing to 10 color printing. Printing on film can comprehensively use silk printing, embossing and thermal printing technology, which can achieve various effects desired by designers. Comparing the film with direct printing, it is found that the film allows the manufacturers of consumer goods to save various trademarks without saving the packaging box. This saves a lot of space to place all kinds of printed packaging boxes, and also allows manufacturers to change icons more flexibly according to different needs

similarly, if the production line of products needs to be expanded, the film enhances the flexibility of food and beverage manufacturers, which only needs to produce different kinds of products without processing a large number of packaging boxes. At the same time, the film also has advantages in sending and application technology. Now more manufacturers can choose to label the packaging box on the filling production line, which further improves the production efficiency

in addition, the film also has strong durability. Even in the field of labeling, film is also the best choice for food and beverage packaging. When used in concentrated materials or inside containers, the paper is likely to crack or tear, while the film can remain intact. In the printing process, the smoothness of the film surface can ensure the best printing quality. In addition, opaque films can be used, which can be used in a variety of trademark applications. For example, some attractive graphics can be printed on the inside trademark side of the transparent container, and these images can be seen through the packaging container. On the other side of the trademark, the information needed by customers (product catalogue, instruction manual, etc.) is printed. It is the opacity of the trademark that allows paper products processors to print on both sides of the substrate

in addition to its advantages in appearance and durability, the film also has the characteristics of low initial start-up cost, making it the preferred material for trademark printing operations of any length. Other technologies, such as mold forming, have high initial preparation costs. Using film to produce multicolor packaging decorations can save a lot of money

in addition, pressure-sensitive films expand the technical scope of production operations. The film label can obtain the maximum production efficiency on the narrow rotating processing equipment. At the same time, the emergence of digital printing technology and supporting advanced coating technology also provides manufacturers with a way to produce shorter printed labels and professional or seasonal trademarks. The film can meet the needs of packaging products with complex curve shape and texture requirements closely related to food and beverage packaging, and it does not need to consider whether the packaging container used is glass or plastic

not only film

although the bottom of film material is very important, the structure of pressure-sensitive (PS) layer provides food and beverage manufacturers with a variety of design options

adhesives: compared with direct printing or heat transfer printing, pressure-sensitive adhesives can provide better adhesion on more material surfaces. A variety of PS adhesives allow packaging designers and manufacturers to choose the right adhesives to form a beautiful appearance on glass, high density polyethylene (HDPE) or regular polyethylene packaging boxes

whether the plastic is transparent, colored, textured or low surface energy, the pressure-sensitive adhesive can meet the conditions. In fact, the performance of transparent "no trademark appearance" depends on the wettability of trademark adhesive to ensure the seamless combination with the packaging box below. Paper products processors can use solvent-based or water-based adhesives designed for excellent transparency characteristics

the newly developed reusable adhesive allows the trademark to be removed and applied many times within a specific period of time after initial use. This function of removing and replacing trademarks cleanly helps reduce the need to throw away boxes and contents. Other adhesives can be selected according to actual needs, as long as this material will not fade or shift on the surface of the packaging box. Designers should also consider that the adhesive is likely to be exposed to the surface of the items in the packaging box. When some food and beverage products may cause problems in some adhesive systems that also meet the B1 oxygen index value oi ≥ 30%, the adhesive can be selected according to the performance of PS adhesive against the items in the packaging box, so as to reduce the possibility of trademark gradual damage and falling off

surface coating: surface coating optimizes the printability of materials and ensures compatibility with various flexographic printing inks, rotary silk printing inks, UV inks, relief rotary printing ink systems and hot molding systems. This adaptability means that the printing technology and color used in the packaging trademark made of pressure-sensitive film are truly unlimited. Therefore, when designing pictures, designers are only limited by their imagination, without considering the problems of technology and process

peeled backing paper: backing paper is often peeled off and discarded, so it is often forgotten, but peeled backing paper is an essential part of PS film structure. The stripped backing paper helps to improve positioning, stability and traceability in the process of paper product processing, printing and sending processing. Transparent film stripping liner is stronger than many paper liners, which eliminates the crushing of web paper and provides excellent die-cutting performance. It is worth noting that the film peel backing paper has a smooth surface. This smoothness is very important, because in the peeling process, the surface of the adhesive is the reflection of the surface of the backing paper. In the process of contacting with the surface of the packing box, the smoother the adhesive surface is, the more likely it is to form a suitable humidity and "trademark free appearance"

paper products processors who have been working hard to develop a prominent stiff trademark can take advantage of the unique advantages of pressure-sensitive films. For example, the film can be made into a rigid trademark by brushing or dyeing

strict matching

like the products they represent, packaging trademarks also face very harsh conditions. According to different products, trademarks may face very extreme environmental factors, such as high temperature and cold, humidity and exposure to products in packaging. At this time, the trademark should not only remain sticky, but also remain clear, readable and attractive. Therefore, it is very important to match the application requirements with the special label film

in the field of food and beverage, double oriented polypropylene (BOPP) has been the most important material for many years. BOPP materials are transparent, white and silver, which are famous for their durability. For example, condiments such as ketchup or appetizers can be transferred from the cold environment of the refrigerator to the hot and humid environment of the picnic table in summer, and then put back. This repeated concentration and evaporation is likely to destroy less durable materials, but BOPP will still maintain its original properties in these back and forth changing environments

in addition to the temperature limit, BOPP can also protect the properties of the products in the package. Although it is generally believed that food and beverages may not be as corrosive as some products, the acidity of pickle juice or hot soy sauce will challenge the adhesion of ink on any label. BOPP ensures excellent ink adhesion through surface coating, and has been the standard load material of "trademark free appearance" for more than ten years. In recent years, the development of low thickness BOPP has provided cheaper and more suitable common films for pressure-sensitive film manufacturers

the trademark must meet the shape and surface of various packages. In particular, extrudable packaging containers have been widely used in some fields of condiment market. The film meets the final requirements of the soft trademark and can be bent and stretched without breaking. Polyethylene, modified polypropylene and styrene plastic films are ideal materials for full extrusion, semi extrusion and rigid packaging containers cured by watering for more than 1 week. Like BOPP, these plastic films can be designed to resist tearing, moisture, abrasion and other challenging environments, and all can remain completely printable and extrudable

first impression

food and beverage manufacturers are eager to attract attention, increase market share and expand the shelf space of their products, so they continue to design new packaging materials to distinguish their products from competitors. Irregular shaped glass bottles with mixed curves and textured surfaces have been widely used in the market, especially in the field of new beverage industry with fierce competition

paper products processors who have been working hard to develop a prominent stiff trademark can take advantage of the unique expertise of pressure-sensitive films. For example, the film can be made into a rigid trademark by brushing or dyeing. Phosphorescence, fluorescence or plastic film treated with metal can make certain packaging in shopping malls more distinctive. Paper product processors can also choose to use standard mode or customer designed mode to form relief on a variety of films. Miniature relief can also be achieved and can provide two-dimensional and three-dimensional holographic patterns, bouncing or flashing light outside
