Spout pouch: Spout pouch is also called Pot Spout Bag. Spout pouch is based on the development of stand-up pouches, a new beverage, jelly packaging bags, and now also used in cosmetics.

Through the bag (generally stand-up pouches), add a cap of high-pressure polyethylene (HDPE) Spout , and the formation of plastic bags with mouth (Spout pouchs). According to the different mounting positions of the Spout , the Spout bags can be divided into two types: upright mounting type and slant mouth mounting type. According to the different shapes of the plastic Spout s installed on the bags, the plastic bags with Spout s can be divided into two kinds: long and short Spout s. The processing of plastic bags with Spout s (Spout bags) is divided into two primary links of bag making and welding Spout ; each link has a high level of technical requirements; if not mastered well, it is easy to produce broken bags, leakage, and other quality problems.

Spout pouch is based on the development of stand-up pouches, a new beverage, jelly bags.
The structure of the Spout bag is mainly divided into two parts: Spout and stand-up pouches. Stand-up pouches and ordinary four-seal stand-up pouches in the system are the same but generally use composite materials to meet the requirements of different food packaging.
The Spout part can be regarded as the mouth of a general bottle with a straw. The two parts are tightly combined to form a beverage package to support sucking, and because it is a soft package, there are no sucking difficulties; the contents of the seal are not easy to shake, which is ideal for new beverage packaging.
The most significant advantage of the sippy bag over common packaging forms is portability. Spout pouchs can be easily put into a backpack or even a pocket and can be reduced with the contents of the reduced volume, more convenient to carry.
Soft drink packaging on the market, to PET bottles, composite aluminum paper bags, and cans as the primary form, in the increasingly apparent homogenization of competition today, packaging improvement is undoubtedly one of the powerful means of differentiation of competition.
Spout pouch, both the PET bottle repeat packaging and composite aluminum paper package of fashion, while in the printing performance also has the advantages of traditional beverage packaging can not be compared.
Because of the basic shape of the stand-up pouches, the display area of the pipette bag is significantly larger than the PET bottle and better than the Tetra Pak pillow, which can not stand a class of packaging.
Of course, because the pipette bag belongs to the flexible packaging category and therefore does not apply to the packaging of carbonated beverages, fruit juice, dairy products, health drinks, jellies, and other food products, it has a unique advantage.

The Spout pouch is based on the development of stand-up pouches, a new type of plastic flexible packaging that is divided into two parts, stand-up, and suction Spout ; stand-up refers to the bottom of a layer of film to support the stand-up; the suction Spout is a new material PE blow molding, injection molding and become, fully meet the requirements of food grade.

What is the Spout pouch made of?

Structure Composition.
The structure of the Spout bag is mainly divided into two parts: Spout and stand-up pouch.
The stand-up pouch part is the same as the ordinary four-seal stand-up pouch in structure but generally adopts composite materials to meet the requirements of different foods. The Spout part can be regarded as the mouth of a general bottle with a straw. The two parts of the close combination of the formation of beverage packaging to support sucking, and because it is a soft package, there is no difficulty in sucking the situation; the contents of the seal are not easy to shake, which is an ideal new beverage packaging!

Commonly seen on the market, suck mouth pouches are generally made of three or more layers of film composite, including the outer layer, the middle layer, and the inner layer.
The outer layer is printed material. Currently, on the market, commonly used vertical bag printing materials are cut down from ordinary OPP, and PET, PA, and other high-strength, high-barrier materials can be based on the
According to the situation to choose. Ordinary materials such as BOPP and dull BOPP can pack dry fruit solid products. If packing liquid products, PET or PA materials are generally used.
The interlayer is generally made of high-strength and high-barrier materials, such as PET, PA, VMPET, aluminum foil, etc. Moreover, RFID requires that the surface tension of the interlayer material should meet the composite requirements and must be compatible with the adhesive.
The surface tension of the interlayer material should meet the composite requirements, and it must have good affinity with the adhesive.
The inner layer, i.e., the heat sealing layer, is generally made of PE, CPE, CPP, and other materials with low-temperature solid heat sealing performance. The surface tension of the composite surface should meet the mixed requirements and should have good
anti-pollution ability, anti-static ability, and heat sealing ability.

Spout pouch processing technology

Spout pouch production is more complex, including composite, heat sealing, curing, and other methods; each process requires strict control.


Spout pouchs need to be heat-sealed, so the pressure Spout position of the ink must use high-temperature ink; if necessary, increase the curing agent to enhance the sealing of the pressure Spout position.
One point to note: the pressure Spout part of the general does not carry out matte oil printing. Because there are differences in the temperature resistance of some domestic matte oils, many flat oils in the heat sealing position of high temperature and high-pressure state
Under the high temperature and high-pressure conditions of the heat sealing bit, many matte oils can easily be anti-sticking. At the same time, the general manual pressure mouth of the heat sealing knife, no sticky high-temperature cloth, matte oil anti-sticking is easy to accumulate in the pressure mouth sealing blade.

2.Pieces of composite

Composite can not use ordinary glue and must be suitable for high-temperature glue Spout . For a high-temperature cooking Spout bag, glue must choose high-temperature cooking grade glue.
Once the bag is added to the suction Spout , the same steaming conditions, it is likely that because the final pressure relief in the steaming process is unreasonable or insufficient pressure retention, it will be in the bag body and suction Spout of the combination of the bit, the
Produce swelling leads to bag breakage because the location of bag breakage is mainly concentrated in the weakest position of the combination of hard and soft. Therefore, to add Spout high-temperature cooking bags, the production needs to be more careful.

3.Heat sealing

Setting the heat sealing temperature needs to consider the following factors: the characteristics of the heat sealing material, the thickness of the film, the number of stamping, and the size of the heat sealing area. In general, when the same part of the heat pressure times
When the number is more, the heat sealing temperature can be set lower.
Appropriate pressure must be applied during the heat-sealing process to promote the adhesion of the thermal cover material. However, if the pressure is too high, the melted material will be extruded, which not only affects the analysis and troubleshooting of bag flatness but also affects the bag’s ability to be sealed.
Troubleshooting analysis and troubleshooting will also affect the heat-sealing effect of the bag and reduce the heat-sealing strength.
The heat sealing time is not only related to the heat sealing temperature and pressure but also to the performance of the heat sealing material, heating method, and other factors. Specific operations should be adjusted according to the actual commissioning process of different equipment and materials.
