Fashions always come and go. Unexpectedly, you may have gone back and forth for several times. As a popular type in the industry, the packaging structure of packaging bags seems to have more vitality, because it takes a long time to change. The following are some packaging bag structures that have occurred or are changing. 1. The packaging box is opened in more ways and easier to operate than before. Today’s packaging boxes will use some small accessories to switch, such as the zipper of some vertical bags. When using, you don’t need to tear the packaging bags, just unscrew them. There has also been significant progress in the mechanical aspect. With the increase of functions, you can provide one-stop service from filling to packaging in the shortest time. 2. Clear high barrier film. The barrier properties of a new generation of clear films and coatings begin to approach those of metal sheets and aluminized films. It provides an opportunity to display, so that people can intuitively see those very appetizing foods. The packaging structure is also convenient for preventing food from being heated in the microwave oven. 3. The preferred packaging for new products. After years of development, it is generally believed that flexible packaging will sweep all products. Typical examples include tuna and pet food. After decades of filling and packaging, bactericidal packaging bags have become popular. Recently, baby food glass bottles have also been replaced by sterilized packaging bags. 4. One step faster than others. Since it is no longer a novel thing to use a larger elastic vertical bag to package tomato sauce, the small bag packaging of other condiments is not far away. The success of the trial sales in Europe, Asia and Latin America proves that this is a miracle. The new packaging of shampoo and detergent is launched when they are actually mature, as is the case with canned fruits. 5. The global cereal flexible packaging industry is moving forward slowly. Whether in the low-end or high-end market, flexible packaging has entered the sight of cereal manufacturers. However, the experts acknowledged that if they want to change to flexible packaging in a short time, the manufacturers will invest a lot in packaging machinery. Moreover, although there are many advantages of renewable resources, it is impossible to directly replace single flexible packaging materials with recycled cardboard. This is mainly because soft packaging does not mean that consumers in the whole country, especially Americans, will accept it. 6. There will be more strata in the process of composite compression. In fact, adding layers in the flexible packaging structure can save costs and increase performance. It requires more precise control of layers 3-5 layer film compound extrusion production line. 7. Suitable flexible packaging Xingtai. Contemporary packaging style can design more shapes than before. Packaging consumer goods companies are eager for new packaging shapes. For them, it is very important to highlight the products on the shelf. The vertical bag with the shape of almost two curved spaces is no longer popular, although the machines of outside machinery companies are almost all producing the conical vertical bag. At the same time, with the shape of the vertical bag becoming more complex, how to control the design waste is a challenge that needs to be faced. 8. The widespread impact of packaging bags. Because the packaging bag structure can be customized according to the requirements, many new physical structures of products emerge: liquid, viscous, powder, granular and particulate. Subsequently, there are intersections between products, including food and beverage, cosmetics, medical care, pet food, automobile, medicine and agricultural products. Now the filling speed of flexible packaging has not reached the speed of common packaging boxes, and the single gap is decreasing, especially in the field of dry products.
