Germany's paper-plastic composite beverage packaging combines ease of opening and anti-counterfeiting

The outer surface of a beverage box in Germany is a thin cardboard layer with a layer of aluminum foil inside. Of course, the aluminum foil is first compounded with other plastic films and then combined with cardboard. Cardboard itself has its advantages, light weight, a certain degree of strength, easy to print and shape, the molded carton is conducive to the collection of packaging and stacking storage; aluminum foil and plastic composite film has good permeability barrier properties, It can not only prevent the liquid from seeping out, but also play a role in making the quality of the beverage lingering. Same with n;/ plastic film also has a good heat sealing performance, paper plastic box seal molding, in fact, is to rely on it to achieve, and the time is short, fast, suitable for the production line processing.

The printing of the exterior of the paper-plastic box is very beautiful, and most of them have been treated with glazing. Its color pattern and title let people know at a glance which type of beverage is inside. Usually, except for the trademark and the manufacturer, the various ingredients of the beverage are meticulously marked in a small form and examined by the relevant department. In addition, the shelf life of the drink is printed on the top of the box, and the text on the bottom of the front of the box is printed with the words “use deadline to see the top of the tray.” The side of the drink box is printed with “Can be opened after Refrigerant top three, etc. It can be said that almost all fruit beverages use this kind of packaging.

It is also worth noting that the beverage box is opened and resealed. There are several new beverage container sealing openings on the German market today:

One is to make a small mouth at the corner of the top of the beverage box, and then the square plastic cover that has been processed and formed is glued to death. The cover consists of two parts, one is the adhesive fixing part, and the other movable part and the fixing part are connected together by a small shaft located in the middle. The movable part can be rotated about 90'. The movable part is turned downwards at the opening. Open, turn up to close, and design with small parts for positioning and clamping.

The other type is also a two-part force-shaped plastic cover that is glued to the mouth of the top of the beverage box. The two parts are processed and connected together, and the other end can be opened and closed. The opening of the drink box is very elaborate. It does not open a large mouth like the first method, but consists of a small conical å­‘L and small round holes. The tapered hole can pour the beverage, and the small round hole into the air facilitates the pouring of the beverage. These two holes are sealed by a small piece of composite aluminum foil, which not only ensures the sealing effect, but also discovers in time whether the beverage box has been opened.

The third method is to attach a spiral plastic circular lid at the opening of the beverage box. The lower part of the circular lid is adhesively fixed to the carton, and the upper part is usually composed of two parts. One is a rotating lid and the other is The small part sticks to the fixed part, and it is connected to the screw cap by several plastic thin wires. If the screw cap is opened, the plastic thread will break, and immediately the box of beverages will be opened.
