At present, the market share of plastic flexible packaging is gradually expanding. It is expected that it will maintain a good growth momentum in the next few years. Flexible packaging based on plastic film plays an important role in various packaging products. With a volume of more than 40%, here are some flexible packaging structures that have occurred or are changing.

The status quo and the latest development trend of plastic flexible packaging materials

The box is opened more and is easier to handle. Compared with before, the current box will use some small accessories to make the switch, like some zippers of the stand, you don't need to tear the bag when you use it, just need to unscrew it. There has also been significant progress in machinery, and with the increase in functionality, one-stop service from filling to packaging can be provided in the shortest possible time.

Clear high barrier film. The barrier properties of the new generation of clear films and coatings are beginning to approach the foil and aluminized film. It provides an opportunity to showcase those very appetizing foods. This packaging structure also facilitates the heating of food in a microwave oven.

The preferred packaging for new products. After years of development, it is widely believed that flexible packaging will sweep all products. Typical examples are tuna and pet food. After decades of canning, sterilizable bags are popular. More recently, baby food glass bottles have also been replaced by sterilizable bags.

A step faster than others. Since packaging ketchup with a flexible, larger stand is no longer a novelty, the pouch packaging of other condiments is not far off. The success of test sales 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, as was the case with canned fruit.

The global cereal soft packaging industry is moving slowly. Whether in the low-end or high-end market, flexible packaging has entered the sight of cereal manufacturers. But experts admit that if they want to change into flexible packaging in a short period of time, manufacturers will invest a lot in packaging machinery. Also, while renewable resources have many advantages, it is unlikely that soft packaging materials will be replaced directly with recycled paperboard. Mainly because soft packaging does not mean that consumers across the country will accept it, especially Americans.

There will be more layers in the composite extrusion process. Listening to it, I feel that this is not true. In fact, adding layers in the flexible packaging structure can save costs and increase performance. what happened? It requires more precise control of the layer. The 3-5 layer film composite extrusion line is subject to the size of the extruder and the design of the mold. The 7-9 layer composite extrusion line produces better and thicker flexible packaging materials and costs less because there is no need to redesign the structure. One is to use an inexpensive resin as the expanded layer. Another is to separate the moisture barrier into two thinner layers, one of which is spared to prevent pinholes from being connected to other layers. This method also increases the number of moisture barriers, further reducing the permeability. There are a number of techniques that can separate moisture-proof materials into many layers, and data indicates a linear increase in water resistance.

Suitable soft package shape. Contemporary packaging styles can be designed with more shapes than before. Packaging consumer goods companies are eager for new packaging shapes, and for them, products that stand out on the shelves are very important. A stand with almost the shape of two curved spaces is no longer popular, although the machine of the outside machinery company almost always produces such a conical stand. At the same time, as the shape of the stand is more complicated, how to suppress design waste is a challenge that needs to be faced.

The wide impact of the bag. Because the structure of the bag can be customized according to requirements, many new physical structures have emerged: liquid, sticky, powdery, granular and particulate. Along with this, there is an intersection between products and products, including food and beverages, cosmetics, health care, pet food, cars, drugs and agricultural products. The filling speed of flexible packaging has not yet reached the speed of common packaging, but the gap is decreasing, especially in the field of dry products.

Despite the rapid development of production capacity in the plastic flexible packaging industry, flexible packaging companies must keep up with the pace of market recovery and effectively adjust product mix in a timely manner. Potential is important, but finding the right direction is the key to the company's continuous advancement. We should spare no effort to study the market and research needs, carry out in-depth development, focus on quality improvement, and develop functional packaging materials with certain technical content to welcome the new one. Round the global green economy. Product packaging should gradually change from the simple, protective and passive packaging forms to the branded, market-oriented and active packaging forms.
