A mouthfuled pouch is formed by attaching a capped low pressure polyethylene (HDPE) to the bag (typically a stand-up pouch). In addition to the advantages of easy opening and sealing for bottles and barrels, the bag with mouth has the advantages of less packaging material consumption, high printing and decoration level, low storage and transportation costs, low waste disposal capacity, etc. It is environmentally friendly packaging. According to statistics, compared with bottles and barrels of the same capacity, the consumption of raw materials for mouth-packed bags can be reduced by more than 30%, the storage and transportation costs of packaging materials are reduced by more than 60%, and the amount of garbage disposal is reduced by more than 5 times. These advantages are determined. The bag with the mouth will have an extremely broad development prospect.

Classification Of Pouches
According to the position of the hard mouth, the mouth bag can be divided into two types: upright installation and oblique installation. The upright-mounted spouted pouch is a middle part of the top of the bag with a hard mouth. Its shape and function are similar to those of a normal bottle, and it is suitable for liquid packaging with a capacity of less than 1000ml. The oblique mouth-mounted bag with a mouth is cut at an angle of 17 to 45 degrees in the upper left corner of the bag, and the mouth is mounted on the face of the slit so that the axis of the mouth is at an angle to the axis of the bag. The shape and function of this bag is similar to that of a general rigid plastic drum, and is suitable for liquid packaging with a capacity of more than 500ml.
According to the shape of the plastic nozzle installed on the packaging bag, the mouth bag can be divided into a long mouth type and a short mouth type. The long mouth type bag means that the installed plastic mouth has a long straw in addition to the screw seal portion and the heat sealing portion. When the long mouth is installed on the packaging bag, the straw portion can be inserted into the bag to facilitate the consumer to absorb the liquid in the bag. Long-mouth flexible bags are generally suitable for liquid beverage packaging, such as sippy jelly, juice drinks, tea drinks, etc., and can also be used as a packaging for automatic ink extraction from printing presses. The short-mouth type packaging bag means that the plastic mouth has only two parts of the screw sealing portion and the heat sealing portion, and the package in the bag can be taken out by pouring or squeezing. Short-mouth bags can be widely used in the packaging of various forms such as liquid, granules and powder.
In addition, in recent years, some large-mouth bagged square bags have appeared. The maximum capacity has reached hundreds of liters. A large mouth is installed at the top of the bag, which can be used as a product for juice, ketchup, cooking oil, and daily chemicals. The former storage and transportation package.
Application With Pouches
The bag with mouth was born in Japan and Germany in the mid-to-late 1980s, and it was rapidly promoted worldwide in the mid-to-late 1990s. At present, in developed countries and regions such as Europe, America and Japan, the application of mouth-packed bags has been quite extensive. According to relevant Japanese data, the average annual growth rate of mouth-packed bags in the Japanese market exceeded 40% between 1998 and 2001. In 2001, the demand for long-nosed bags reached 575 million. After the implementation of the garbage disposal fee by volume in Taiwan Province of China, the development of the mouth-filled packaging bag was greatly promoted. In addition to the aerated beverage, the packaging of various liquid products began to adopt the mouth-packing bag.
In the late 1990s, China began to introduce the technology of mouth-packing bags. The most influential products were CiCi, which can be sucked by Guangdong Xizhilang. It uses long-mouth bags, which are exquisitely printed and easy to use. . At present, more than 10 brands of sipable jelly such as Xizhilang, Dailybao, Jinwa, Panpan, and Kiss are also equipped with mouth bags. In addition, the short-mouth soft bag also entered the domestic market in 2000. The products already on the market include juice drinks, chicken essence, monosodium glutamate, soy sauce, pepper, detergent, fabric softener, hand soap and so on. These colorful packaging is quickly accepted by the majority of users. In the future, mouth-opening bags will have greater development in China. Such as washing powder, gasoline, engine oil, edible oil and many other products can use this large capacity three-dimensional packaging bag with handle and mouth; winter northern market is the peak season of liquor sales, if you use a long mouth type with a capacity of 200 ~ 300ml Packing bags of white wine can be convenient for drinking by field workers; special places such as famous scenic spots and football stadiums are also very suitable for the use of such packaging.
Development Of Related Technologies
The development of the mouth bag is closely related to equipment and technology such as stand-up bag making machine, automatic mouth sealing machine and automatic filling machine.
At present, packaging machinery companies in Germany, Japan, Italy and other countries can provide complete sets of equipment such as self-standing bag making machine, automatic mouth sealing machine and automatic filling machine with mouth bag.
China’s packaging machinery industry is also following the development trend of mouth-packing bags. Now many bag-making equipment manufacturers have launched self-supporting bag-making machines. Their main performance and indicators have been close to the international level and exported.
China’s mouth bag filling machine has also developed rapidly. Shantou Anping, Yuedong and other manufacturers have introduced a fully automatic stand-up bag liquid filling machine, and close to the foreign technology level, some of the equipment exports. However, due to the diversification of packaging materials and the continuous development of the design of the mouth-filled packaging bags, it is urgently needed to invest in the development of liquid, powder and granular filling machines with higher automation and higher production efficiency, especially the oblique-mouth bag filling machine.
However, the development of automatic mouth sealing machines in China is relatively slow. Many flexible packaging manufacturers and food companies still use simple manual sealing machines to install plastic nozzles. In 2001, Zhongshan Xinhongye Automation Industry Co., Ltd. of Guangdong Province developed the NCA1601-30 bag automatic mouth sealing machine, which greatly satisfied the market demand. However, the development of automatic mouth sealing machines in China is relatively slow. Many flexible packaging manufacturers and food companies still use simple manual sealing machines to install plastic nozzles. In 2001, Zhongshan Xinhongye Automation.
