At present, there are two methods of filling nozzles in stand-up pouches in China: manually installing nozzles and heat sealing nozzles. The temperature is transferred to the mouth by heat conduction, which melts the mouth and welds it with the PE sealing layer of the bag.
The finished bags after production must be inspected by a special detector to prevent leakage, damage, etc. At the same time, the physical properties of the stand up pouch must be stretched to test the maximum tensile force and pressure.
The scope of use of stand up pouch nozzles
The structure of the stand-up pouch nozzle is mainly divided into two parts: the suction nozzle and the stand up pouch. The structure of the stand up pouch is the same as that of the ordinary four side stand up pouch, but composite materials are generally used to meet the requirements of different food packaging.
The nozzle part can be regarded as adding a straw to the mouth of a general bottle. The two parts are closely combined to form a beverage package that supports smoking, and because it is a flexible package, there is no difficulty in smoking, and the contents are not easy to shake after sealing, so it is an ideal new beverage packaging.
Compared with common packaging forms, the stand up pouch nozzle has the advantage of portability. The suction nozzle of the stand up pouch can be conveniently put into a backpack or even a pocket, and can be reduced in size as the content decreases, making it more convenient to carry. At present, soft drink packaging in the market is mainly in the form of PET bottles, composite aluminum paper bags, and cans.
In today’s increasingly homogeneous competition, packaging improvement is undoubtedly one of the powerful means of differentiated competition. The stand-up pouch nozzle combines the repeated packaging of PET bottles and the fashion of composite aluminum paper bags. At the same time, the printing performance is also unmatched by traditional beverage packaging. Due to the basic shape of the stand-up pouch, the display area of the stand up pouch nozzle is large. Significantly larger than PET bottles, and better than Tetra Pak pillows that cannot stand up.
It is generally used to pack liquids, such as soy milk, soy sauce, vinegar, fruit juice, beverages, laundry detergent, milk, etc. Since the suction nozzles of the stand-up pouches have various forms, there are long nozzles for sucking jelly, juice, and beverages, and there are also nozzles for washing products. With the continuous improvement, development and application of stand up pouch nozzles, most of the washing liquid and softener in Japan and South Korea are packaged with stand up pouch nozzles, and are loved by foreign friends.
This is the rhythm of the gradual transfer from plastic packaging bags to self-supporting pouch nozzles. The winter in the north is cold, and baijiu is very popular among northern men. Drink less to keep fit and increase body heat. If people use the flexible package with long spout to make the package, then it can be convenient for people who work in the field to use body temperature or warm water with hot water, which is convenient for drinking. Today’s advertising industry is developing rapidly.
If you make full use of the advantages of convenient printing and good printing quality of flexible packaging, you can print advertisements on the suction nozzle of the self-supporting pouch, which is easy to carry and spread widely. It will kill two birds with one stone.
The production process of stand up pouch nozzle
The suction nozzle of the stand up pouch is composed of two parts: the suction nozzle and the stand up pouch. Each link has high requirements on the process. Bags, leaks, etc. In order to avoid this situation in the production of stand up pouches, attention must be paid to the links such as punching, placing the bottom of the bag, and heat sealing the bottom, especially the combination of the four-layer and two layer stand up pouch is prone to bag breakage, and the horizontal sealing knife is If it is not enough, it is necessary to install a heat sealing knife, and some parts need to strengthen the heat sealing.
In addition, stand up pouches with spouts require good opening performance. Surface static electricity should be removed when making pouches to avoid adsorption between pouches, which is not conducive to pouch removal by the spout sealing machine.
