Japan Develops New Type Paper Tube Juice Jar

Japan has developed a laminated container suitable for various liquids using paper tubes as its basic material. The container of this type of container is made of paper, and the upper and lower ends are the same as those used in the past, and the iron sheet is used. The paper tube is 1 mm thick and made of high-strength paper. The interior is a layer of polyester film, and a layer of metallic aluminum is evaporated and coated with polypropylene to seal it. The outside is also a layer of polyester film. The inside is printed with a pattern and sealed so that it is not easy to peel off. When filling fruit juices, the temperature of the filling liquid should be as high as 100 degrees Celsius, and the internal pressure will be reduced after cooling. Although this container is made of paper, it will not be damaged by decompression, and the airtightness is good. The weight of the barrel is about half that of the iron sheet. The printing fee for the entire can can also be reduced by about 20%. The paper tube juice cans are not easy to be broken, the packaging is lightweight, and has the characteristics of unique flavor and long shelf life.
