Application of the hottest paper ring label in the

The application of paper ring labels in the packaging of United cup yoghurt

the labels of plastic cup yoghurt can be divided into three types: top label (cover film), plastic cup circumference label (ring label), and adopt a unique activity design and bottom label. The advanced filling line is equipped with appropriate labeling equipment, which can label the side and bottom of the plastic cup. At present, only Guangming, Yili, Danone, Mengniu and other dairy products in the domestic market produce yogurt with paper ring labels, and basically do not use the bottom label

domestic ring standards are generally heat shrinkable film ring standards and paper ring standards. Paper ring label can achieve better packaging effect than heat shrinkable film ring label. The ring label is generally made of 90 ~ 120 g/m2 paper, and the back of the label is coated with hot melt adhesive, which has good stiffness, which can make the plastic cup thinner and the packaging speed faster. The stiffness of the cup is greatly enhanced by sticking the hot melt adhesive to the cup wall of PS sheet. Ordinary plastic cups use PS sheet with a thickness of 1 About 2mm, the wall thickness of the cup body after stamping is 0 8mm~0.5mm。 The thickness of plastic cup sheet with paper ring label can be reduced to less than 0.8mm, and the wall thickness of cup body after stamping can reach 0.12mm, which can save more than 40% of the sheet cost and improve the packaging speed

domestic yogurt adopts paper ring standard, and the packaging speed ranges from 6000 cups/hour to 50000 cups. The physical properties that Jinan Shijin glass magnesium plate universal experimental machine can meet include compression test/hour. Under the condition of rapid packaging, the packaging speed of ring label can reach 7 meters/minute, which requires that the label paper has a high tensile strength of control, measurement and operation 1 integrated structure

the ring label provided by the supplier is in the form of drum. The number of labels and the method of cutting paper ring labels are determined according to the number of cups and the packaging method. For example, the Aloe Yogurt of Shanghai Guangming is 6-Cup, and the packaging material provided by the packaging material supplier is 12 label patterns arranged vertically. After being cut into uneven strips on the filling equipment, two 6-Cup yogurt packages are carried out at the same time

domestic yogurt is packaged in multiple cups, such as 6-Cup, 8-Cup, 12 cup, 24 cup and other packaging methods. Take Germany hassia32/48 yoghurt filling machine as an example, fill stirred yoghurt with a filling volume of 125 g/cup and a plastic cup size of 65 × 65mm yogurt can be packaged for 24 cups (commonly known as 24 cups), 32 times per minute, and 46080 cups per hour

ps sheet thickness and molding temperature will affect the bonding effect between the ring label and the cup body. The ring label should be well matched with PS sheet. After the PS sheet passes through the plastic cup die head, the hot melt adhesive coated on the back of the ring label is melted by the heat stored in the PS sheet and pasted with the plastic cup. The pasting temperature is generally 90 ℃ ~ 100 ℃. The temperature and thickness of the molded cup determine the amount of heat stored in the cup. During the commissioning of yogurt filling equipment, it is necessary to test the machine for many times, and the supplier of ring label selects the appropriate hot melt adhesive to match with PS sheet plastic cup. After the yogurt filling equipment is successfully debugged, the type and thickness of PS sheet, the type and coating thickness of hot melt adhesive, and the molding temperature of plastic cup should be kept unchanged. If one of the conditions changes, good pasting effect will not be achieved. Plastic cup yoghurt uses a torus label, which can convey more product information than just using a film label. More and more domestic dairy enterprises have invested heavily in the purchase of ring labeled filling equipment, creating more economic benefits for enterprises
