Development Trend of flexible packaging materials and packaging structures

Fashion always comes and goes. Inadvertently, the various fashions next to you may have gone several times. As a popular industry, the packaging structure of flexible packaging looks more vital because it takes a long time to change. The following are some flexible packaging structures that have occurred or are undergoing changes. 1, the box is opened in more ways and easier to operate. Compared with the past, the current box will use some small accessories to make the switch, like some zipper of the vertical bag, you do not need to tear the bag when using, just need to unscrew it. There has also been significant progress in machinery. With the increase of functions, one-stop service from loading to packaging can be provided in the shortest possible time. 2, clear high barrier film. The barrier properties of the new generation of clear films and coatings begin to approach metal sheets and aluminized films. It provides an opportunity to show, enabling people to intuitively see those very appetizing foods. This packaging structure is also convenient for food to be heated in a microwave oven. 3. 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 canned 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 Recently, baby food glass bottles have also been replaced by sterilizable packaging bags. 4.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 elastic stand bag, the small bag packaging of other condiments is not far away. The success of Trial sales in Europe, Asia and Latin America proves that this is a miracle. The new packaging of shampoo and laundry detergent is introduced when the time is right, as is the canned fruit. 5. The global cereal flexible packaging industry is moving slowly. Whether in the low-end or high-end market, flexible packaging has entered the sight of cereal manufacturers. However, experts admit that if flexible packaging is to be changed in a short period of time, manufacturers will invest a lot in packaging machinery. Moreover, although renewable resources have many advantages, it is unlikely that flexible packaging materials will be directly replaced by recycled cardboard. This is mainly because flexible packaging does not mean that consumers in the whole country will accept it, especially Americans. 6, there will be more layers in the composite extrusion. Upon hearing this, I felt that this statement was wrong. In fact, adding layers to the flexible packaging structure can save costs and increase performance. What's going on? It requires more precise control over the layer. 3- The 5-layer film composite extrusion production line is subject to the size of the extruder and the design of the die. 7- The 9-layer composite extrusion production line can produce flexible packaging materials with better performance and thicker thickness, and the cost will be lower because there is no need to design the structure. One is to use a cheaper resin as an expansion layer. Another is to separate the moisture-proof layer into two thinner layers, one of which is reserved to prevent pinholes from being connected to other layers. This method will also increase the number of moisture-proof surfaces, thus further reducing the permeability. There are many technologies that can separate moisture-proof materials into many layers, and data show a linear improvement in waterproof performance. 7. Suitable flexible packaging shape. The 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 shelves. It is no longer popular to subtract almost two curved spaces from this shape of vertical bags, although almost all machines from outside machinery companies are producing this kind of conical vertical bags. At the same time, as the shape of the vertical bag becomes more complicated, how to curb design waste is a challenge to face. 8, the wide impact of packaging bags. Because the packaging bag structure can be customized according to requirements, many new product physical structures have emerged: liquid, viscous, powdery, granular and granular. As a result, there is an intersection between products, including food and beverages, cosmetics, medical care, pet food, automobiles, drugs and agricultural products. At present, the filling speed of flexible packaging has not reached the speed of common packaging boxes, but the gap is decreasing, especially in the field of dry products.
