Trends always come and go. Inadvertently, the various trends next to you may have gone back and forth several times. As a popular kind in the industry, the packaging structure of flexible packaging seems to have more vitality, because it takes a longer time to change.

Trends always come and go. Inadvertently, the various trends next to you may have gone back and forth several times. As a popular kind in the industry, the packaging structure of flexible packaging seems to have more vitality, because it takes a longer time to change. Below are some flexible packaging structures that have occurred or are undergoing changes.

1, there are more ways to open the box and easier to operate. Compared with the past, the packaging box now uses some small accessories to switch, like the zipper of some stand-up pouches. When in use, there is no need to tear the packaging bag, just unscrew it. Significant progress has also been made in machinery. With the increase of functions, a one-stop service from filling to packaging can be provided in a short time.

2, a 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 also facilitates the heating of food in a microwave oven.

3, packaging of 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 canning and packaging, sterilizable packaging bags have become 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 Recently, baby food glass bottles have also been replaced by sterilizable packaging bags.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 stand-up 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 the time was right, and the same was true for canned fruits.

5. The global oatmeal flexible packaging industry is advancing slowly. Whether in the low-end or the 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 flexible packaging materials can be directly replaced by 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 layers in the compound extrusion process. I heard it fiercely and 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 of the layers. The 3-5 layer film composite extrusion production line is subject to the size of the extruder and the design of the die. The 7-9 layer composite extrusion production line can produce better and thicker flexible packaging materials, and because there is no need to design the structure, the cost will be lower. One is to use cheaper resin as the expansion layer material. Another is to separate the moisture-proof layer into two thinner layers, one of which is a spare layer to prevent pinholes from connecting with the other layers. This method will also increase the number of moisture-proof surfaces, thereby further reducing the permeability. There are a variety of technologies that can separate the moisture-proof material into many layers, and there are data showing a linear increase in waterproof performance.

7. Appropriate flexible packaging shape. Contemporary packaging styles can design more shapes than before. Consumer packaged goods companies are eager for new packaging shapes. For them, it is very important for them to stand out on the shelf. Stand-up pouches of the shape of almost minus two curved spaces are no longer popular, although machines from outside machinery companies almost all produce 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, but the gap is decreasing, especially in the field of dry products.
