Increased tendency of thin filming of flexible packaging materials

Increased tendency of thin filming of flexible packaging materials
As a popular industry, the packaging structure of flexible packaging looks more vital because it takes a long time to change. Here are some of the flexible packaging structures that have occurred or are changing.
The opening of the box is more and easier to operate. Compared with before, the current packaging box will use some small accessories to do the switch, like some vertical zipper bags, you don't need to open the bag when you use it, just unscrew it. There have also been major advances in machinery. With the increase in the number of functions, one-stop services 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 the metal foil and the aluminized film. It provides an opportunity for display, so that people can intuitively see those very appetizing food. This packaging structure also facilitates food heating in a microwave oven.
The preferred packaging for 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, sterilizable bags are in vogue. More recently, baby food glass bottles have also been replaced by sterilizable bags.
One step faster than others. Since packaging ketchup with a large, flexible stand-up pouch is no longer a novelty, pouch packaging for other condiments is not far off. The success of the test sales in Europe, Asia and Latin America proves that this is a miracle. The new packaging of shampoos and laundry liquids was launched when the time was ripe, and so were the canned fruits.
The global cereal soft packaging industry is slowly moving forward. Whether in the low-end or high-end markets, flexible packaging has already entered the sights of cereal manufacturers. However, experts admit that if you want to change into a flexible package in a short time, manufacturers will invest in packaging machinery will be very much. And, while renewable resources have many advantages, it is unlikely that flexible packaging materials will be replaced directly with recycled cardboard. The main reason is that flexible packaging does not mean that consumers in the entire country will accept it, especially Americans.
There will be more layers in the composite extrusion. As soon as you listen to it, you feel that this statement is wrong. In fact, adding layers in a flexible packaging structure can save costs and increase performance. what happened? It requires more precise control over the layers. The 3-5-layer film composite extrusion line is subject to 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 because there is no need to design the structure, the cost will be lower. One is to use cheaper resins for intumescent laminates. Another is to separate the moisture barrier into two thinner layers, one of which is backed up to prevent pinholes from connecting with other layers. This method will also increase the number of moisture-proof surfaces, thereby further reducing the permeability. There are a number of technologies that can separate moisture-proof materials into many layers, and data show a linear increase in waterproof performance.
Suitable soft package shape. Modern packaging styles can be designed more than ever before. Packaging consumer goods companies are eager for new packaging shapes, for them, it is very important to highlight the products on the shelves. Standing bags with this shape almost minus two curved spaces are no longer popular, although almost all machineries outside the machinery company are producing such conical stands. At the same time, with the more complex shape of stand bags, how to suppress design waste is a challenge that needs to be faced.
The wide impact of the packaging bag. Because the bag structure can be customized according to the requirements, many new product physical structures emerge: liquid, viscous, powdery, granular and particulate. Along the way, there is an intersection between products and products, including food and beverages, cosmetics, health care, pet food, automobiles, drugs, and agricultural products. The filling speed of flexible packaging has not yet reached the speed of common packaging boxes, but the gap is decreasing, especially in the dry product area.
Low-carbon environmental storm has spread to the packaging industry
In recent years, the global low-carbon environmental storm has spread to the packaging industry and put forward the concept of low-carbon packaging. The main contents of low-carbon packaging include lightweight packaging, clean production, green products, energy-saving and emission reduction, and paper and wood. And so on, paper substitute wood is the core of low-carbon packaging. The recycling of waste paper not only reduces the amount of wood, cuts down forests, protects the ecological environment, but also saves energy, saves water, and reduces emissions.
Enterprises need to fully consider social responsibility in product development, closely around the theme of green packaging, the development of packaging materials can be recycled, recycled or degraded, and will not affect the human body and the environment throughout the entire life cycle of the product. Under the premise of meeting the functional requirements of packaging, the amount of waste produced should be minimized, and the development of packaging films and materials should be made lighter and thinner.
At present, the prohibition on the use of EPS foamed plastic cushions has forced Chinese companies to eliminate foamed plastics in the packaging of exported household electrical appliances and switched to environmentally friendly gaskets such as honeycomb paperboard. Honeycomb paperboard is a new sandwich structure made of high-strength cellular paper core and various high-strength kraft papers. It has the advantages of low cost, low material consumption, 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.
At present, there are few varieties of packaging machinery products in China, low technical level, and poor product reliability. There is no advantage in the international market. More than 80% of processing and packaging equipment is imported, facing the development of deep processing of agricultural products, building a conservation-minded society, and developing a recycling economy. The tasks and the market for packaging machinery products are very broad. If packaging machinery companies can accelerate technological innovation and adapt to market demands, they will gain considerable profits.
