The daily chemical packaging structure of flexible packaging seems to be more vital

As a popular kind in the industry, the daily chemical packaging structure of flexible packaging seems to be more dynamic, because daily chemical packaging takes a long time to change. The following are some of the daily chemical packaging structures that have changed or are changing.

The packaging box can be opened in many ways, making the operation more convenient. Compared with the past, today’s packaging boxes use some small accessories as switches, just like the zippers of some vertical bags, so you don’t need to tear the packaging bag when you use it, just unscrew it. Great progress has also been made in daily chemical packaging machinery. With the increase of functions, one-stop service from filling to packaging can be provided in a short time.

Transparent high barrier film. The barrier properties of the new generation of transparent films and coatings for daily chemical packaging are beginning to approach metal foils and aluminized films. Daily chemical packaging provides an opportunity for display, so that people can intuitively see ttube very appetizing foods. This packaging structure also facilitates the heating of food in a microwave oven.

New product packaging. 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, aseptic packaging and daily chemical packaging became popular. Baby food glass bottles have also been replaced by aseptic packaging bags.

Since it is nothing new to pack ketchup in a larger flexible vertical bag, the small bag packaging of other condiments is not far away. The success of test marketing in Europe, Asia and Latin America proves that this is a miracle. New daily chemical packaging for shampoo and laundry detergent was launched in due course, as well as canned fruits.

The global grain flexible packaging industry is progressing slowly. Whether in the low-end or mid-end market, soft daily chemical packaging has entered the sight of oatmeal manufacturers. But experts admit that if you change to flexible packaging in a short time, manufacturers will invest a lot of money in packaging machinery. Moreover, although renewable resources have many advantages, soft packaging materials for daily use are unlikely to be directly replaced by recycled cardboard. Mainly because the soft daily chemical packaging does not mean that consumers across the country will accept it, especially Americans.

There will be more layers in the process of compound extrusion. Upon hearing this, I think this statement is wrong. In fact, adding layers to the soft daily chemical packaging structure can save costs and improve performance. How is this going? Daily chemical packaging requires more accurate control of the layer. The 3-5 film composite extrusion production line is limited by 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 the cost will be lower because there is no need to design the structure. One is to use cheaper resin as the expansion layer. The other is to divide the moisture-proof layer into two thinner layers, leaving one layer to prevent pinholes from connecting with the other layers. This method will also increase the number of moisture-proof surfaces, thereby further reducing permeability. There are many technologies in which moisture-proof materials are divided into multiple layers, and the data shows that the waterproof performance is linearly improved.
