As a popular type of packaging in the industry, flexible packaging structure seems to have more vitality, because it takes a longer time to change. Here are some flexible packaging structures that have changed or are changing.
There are more ways to open the box and it is easier to handle. Compared to the past, today's packaging boxes will use a number of small accessories as switches, such as some vertical bag zippers, when you do not need to tear the bag, just need to unscrew it. Great progress has also been made in the mechanical aspect. With the increase of functions, it can provide one-stop service from filling to packaging in the shortest time.
Clear high barrier film. The barrier properties of the new generation of clear films and coatings are beginning to resemble those of metal sheets and aluminized films. It provides an opportunity to display, so that people can see the very appetizing food directly. The packaging structure also makes it easy to microwave the food.
Perfect packaging for new products. After years of development, it is generally believed that flexible packaging will take over all products. Prime examples are tuna and pet food, which after decades of canning have become popular in germicidal packaging. More recently, baby food bottles have been replaced by germicidal packaging.
One step ahead of everyone else. Since ketchup is no longer a novelty in larger, stretchy sachets, sachets for other condiments aren't far behind. The success of test marketing in Europe, Asia and Latin America proved a miracle. New packages of shampoo and laundry detergent are introduced when the time is right, and so are cans of fruit.
The global cereal soft packaging industry plods along. At both the low and high end of the market, flexible packaging has entered the eyes of cereal manufacturers. But experts admit that if the switch to flexible packaging is made in a short period of time, manufacturers will spend a lot of money on packaging machinery. And, although renewable resources have many advantages, it is not possible to replace flexible packaging materials directly with recycled cardboard. Mainly because flexible packaging does not mean that consumers in the whole country will accept it, especially Americans.
There will be more layers in the compound extrusion phase. A sudden listen, feel that this argument is wrong, in fact, in the flexible packaging structure to add layers can save costs and increase the role of performance. What's going on? It requires more precise control over the layer. The 3-5 film composite extrusion line is subject to the size of the extruder and the design of the die. The 7- to 9-layer composite extrusion line produces better performance, thicker flexible packaging materials, and costs less because there is no need to redesign the structure. One is to use a cheaper resin as an expanded layer. Another is to separate the moisture barrier into two thinner layers, with one layer in reserve in case the pinhole connects to the other layers. This method also increases the number of moisture-proof surfaces, further reducing permeability. There are a variety of techniques for separating moisture resistant materials into layers, and there are data showing linear improvements in water resistance.
Suitable flexible packaging shape. Contemporary packaging styles allow for more shapes than ever before. Consumer packaged goods companies are eager for new packaging shapes, and it is important for them to highlight the products on their shelves. Almost minus two curved Spaces, this shape is no longer popular, although machines from outside machinery companies almost always produce these conical vertical bags. At the same time, as the shape of the vertical pocket becomes more complex, how to curb design waste is a challenge to be faced.
Packaging has a wide range of effects. Because the packaging structure can be customized, many new product physical structures emerge: liquid, sticky, powdery, granular, and particulate. As a result, product-to-product intersections have emerged, including food and drink, cosmetics, health care, pet food, cars, medicines and agricultural products. The filling speed of flexible packaging is not yet as fast as that of a typical box, but the gap is closing, especially in the dry product sector.
Low carbon environmental protection storm has spread to the packaging industry
In recent years, the global low-carbon environmental protection storm has affected the packaging industry, put forward the concept of low-carbon packaging, low-carbon packaging main contents include lightweight packaging, clean production, green products, energy saving and emission reduction and paper instead of wood, paper instead of wood is the core of low-carbon packaging. Waste paper recycling, not only reduce the amount of wood, cut down less trees, protect the ecological environment, but also energy saving, water saving, emission reduction. Enterprises should take full consideration of social responsibility in product development, tightly focus on the theme of green packaging, develop packaging materials that can be recycled, recycled or degraded, and have no impact on the human body and the environment in the whole life cycle of the product. Under the premise that the product meets the packaging function, the amount of waste generated should be reduced as far as possible. Thus showing packaging film, material to light weight, film direction development. At present, the regulations that prohibit the use of EPS foam plastic liners have forced Chinese enterprises to replace foam plastics in the packaging of export household appliances and use environmental protection liners such as honeycomb cardboard. Honeycomb board is a new type of environmental protection and energy saving material with sandwich structure composed of high strength honeycomb paper core and various high strength kraft paper. It has the advantages of low cost, less material, sound insulation, high strength, good impact resistance and so on. Honeycomb board is made of recycled paper, which can replace wood and be recycled after use.
At present, there are few varieties of packaging machinery products in our country, low technical level, poor product reliability, there is no advantage in the international market, processing and packaging equipment more than 80% rely on imports, facing the task of developing deep processing of agricultural products, building a saving society, developing circular economy, packaging machinery products market is very broad, If packaging machinery enterprises can speed up technological innovation, adapt to the market demand, will gain considerable profits.
