The development trend of packaging bag materials and structure

Trends are always coming and going. Inadvertently, the fashions of your edging may have gone back and forth several times. As a popular type in the industry, the packaging structure of the packaging bag seems to have more vitality, because it takes a longer time to change. The following are some of the bag structures that have occurred or are undergoing changes. 1. There are more ways to open the box and it is easier to operate, compared with before. The packaging box now uses some small accessories to switch, like the zipper of some stand-up pouches, you don’t need to tear the packaging bag when you use it, you just need to unscrew it. There have also been major advances in mechanical aspects. Increase, can provide one-stop service from filling to packaging in the shortest time. 2. Clear high barrier film. The barrier properties of the new generation of clear films and coatings are beginning to approach metal flakes and aluminized films. It provides an opportunity to display, so that people can intuitively see those very appetizing food. This packaging structure is also convenient for food to prevent heating in a 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 are tuna and pet food. After decades of filling and packaging, sterilizable packaging bags are popular. Recently, baby food glass bottles have also been replaced by sterilizable packaging bags. 4. One step faster than others. Since it is no longer a novelty to pack ketchup in a larger, flexible vertical pouch, the packaging of other condiments in small pouches is not far away. The success of test marketing in Europe, Asia and Latin America proves that this is a miracle. The new packaging of shampoo and laundry detergent was introduced when they were actually mature, as well as canned fruits. 5. The global oatmeal flexible packaging industry is advancing slowly. Whether in the low-end or high-end market, flexible packaging has entered the sight of oatmeal manufacturers. But experts admit that if it is to be changed to flexible packaging in a short time, manufacturers will invest a lot in packaging machinery. Moreover, although renewable resources have many advantages, it is unlikely that a single flexible packaging material can be directly replaced with recycled cardboard. Mainly because flexible packaging does not mean that consumers in the entire country will accept it, especially Americans. 6. There will be more strata in the compound extrusion process. In fact, adding layers to the flexible packaging structure can save costs and increase performance. It requires more precise control of the layers. .3—5-layer film composite extrusion production line. 7. Suitable flexible packaging Xingtai. Contemporary packaging styles can design more shapes than before. Consumer packaged goods companies are eager for new packaging shapes. For them, the products that stand out on the shelves are very important. Stand-up pouches of the shape of almost minus two curved spaces are no longer popular, although machines from outside machinery companies are almost all producing such conical stand-up pouches. At the same time, as the shape of the standing pouch becomes more complicated, how to suppress design waste is a challenge that needs to be faced. 8. Extensive influence of packaging bags. Because the structure of the packaging bag can be customized according to requirements, many new product physical structures have emerged: liquid, viscous, powder, granular and particulate. What followed was an intersection between products and products, including food and beverages, cosmetics, healthcare, pet food, automobiles, drugs, and agricultural products. Now the filling speed of flexible packaging has not reached the speed of common packaging boxes, and the single gap is narrowing, especially in the field of dry products.
