The tendencies of the soft packaging materials are becoming
As a popular industry, the packaging structure of soft packaging seems to have more vitality, because it takes a long time to change. Below are some flexible packaging structures that have occurred or are changing.
The opening way of the packing box is more and more convenient to operate. Compared with before, now the box will use some small parts to make the switch, like some sacks of zipper, in use, do not need to tear off the bag, just need to unscrew it. Significant progress has also been made in machinery. With the increase of functions, the through-train service from loading 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 begin to approach thin metal sheets and aluminized films. It provides an opportunity for people to see the most appetizing foods intuitively. This packaging structure is also convenient for food to be heated in a microwave oven.
The first choice for new products. After years of development, it is generally believed that soft packaging will sweep all products. Typical examples are tuna and pet food. After decades of canned packaging, sterilizing bags are popular. Recently, baby food bottles are also replaced by sterilizing bags.
A step faster than others. Since it is no longer a novelty to pack ketchup in an elastic bigger bag, other pouch packaging is not far away. The success of trial marketing in Europe, Asia and Latin America proves that this is a miracle. The new packaging of shampoo and laundry detergent is launched when the time is ripe, and so is the tinned fruit.
Global wheat flakes are sluggish. Whether in the low-end or high-end market, flexible packaging has entered the vision of the cereal manufacturers. But experts admit that if we want to change it into flexible packaging in a short time, manufacturers will have a lot of investment in packaging machinery. Moreover, although renewable resources have many advantages, it is not possible to replace them directly with recycled cardboard. The main reason is that soft packaging does not mean that consumers in the whole country will accept it, especially the Americans.
There will be more layers in the compound extrusion. Suddenly, I think this is wrong. In fact, adding layers in the soft packaging structure can save cost and increase performance. What's going on? It requires more precise control of the layer. The 3-5 layer thin film compound extrusion line is controlled by the size of the extruder and the design of the die. The 7-9 layer composite extrusion line can produce better and thicker flexible packaging materials, and the cost will be lower because there is no need to redesign the structure. One is to use a cheaper resin to make an expanded layer. Another way is to separate the moistureproof layer from two thin layers, one of which is standby to prevent pin holes from connecting with other layers. This method will also increase the number of moisture-proof surfaces, thereby further reducing permeability. A variety of technologies can separate moisture barrier materials into many layers, and data show that the waterproofing performance is improved linearly.
Suitable soft packing shape. The contemporary packaging style can be designed more than before. Packaging consumer company is eager for new packaging shape. For them, products on the shelf are very important. Nearly two curved spaces are missing, although the machines outside the machinery company are almost producing this conical vertical bag. At the same time, as the shape of the bag is more complex, how to curb the waste of design is a challenge that we have to face.
The wide impact of the packaging bag. Because the packing bag structure can be customized according to the requirements, many new product physical structures are taken out: liquid, sticky, powdery, granular and particulate. It follows that products and products are intersected, including food and drink, cosmetics, health care, pet food, cars, drugs and agricultural products. At present, the speed of soft packaging has not reached the speed of common packaging boxes, but the gap is decreasing, especially in the field of dry products.
Low carbon environmental storm has spread to the packaging industry
In recent years, the global low carbon environmental storm has been swept into the packaging industry, and the concept of low carbon packaging is put forward. The main contents of low carbon packaging include lightweight packaging, cleaner production, green products, energy saving and emission reduction, and paper instead of wood, and paper is the core of low carbon packaging. Recycling of waste paper will not only reduce wood consumption, cut down trees, protect the ecological environment, but also save energy, save water and reduce emissions. The enterprise needs to take full consideration of the social responsibility in the product development, closely around the green packaging theme, the developed packaging materials can be recycled, recycled or degraded, and it does not affect the human body and the environment in the whole life cycle of the product. The waste can be minimized under the premise that the product meets the package function. Thus, the packaging film and material will develop towards lightweight and film. At present, the prohibition of the use of EPS foamed plastic liner has forced our enterprises to eliminate foamed plastics in the packaging of export household appliances and to use environmental cushions such as honeycomb cardboard. Honeycomb paperboard is a new type of environmental protection and energy saving material composed of high strength honeycomb paper core and all kinds of high strength kraft paper. It has the advantages of low cost, less material, sound absorption and heat insulation, high strength and good impact resistance. Honeycomb paperboard is made of recyclable paper, which can replace wood and can be recycled after use.
