Suction nozzle bag is an emerging packaging method developed on the basis of self-supporting bags, which has more advantages than plastic bottles in terms of convenience and cost. Therefore, the suction bag is gradually replacing plastic bottles, becoming one of the choices of liquid materials such as juice, laundry detergent, sauce and so on.
Structure composition:
The structure of the suction nozzle bag is mainly divided into two parts: the suction nozzle and the self-supporting bag. In popular terms, it is to add a suction nozzle to the self-supporting bag. Among them, the self-supporting bag part is no different from the ordinary self-supporting bag, the bottom has a layer of film to support standing, and the suction nozzle part is a general bottle mouth with a straw. The two parts are closely combined to form a new packaging method - suction mouth bag. Because it is flexible packaging, this packaging is easier to smoke and control, and it is not easy to shake after sealing, which is a very ideal packaging method.
Composite substrate
The nozzle bag is generally multi-layer composite packaging, and like ordinary packaging bags, it is also necessary to choose the corresponding substrate according to different products. For liquid nozzle composite packaging bags, the material structure is generally PET//NY//PE, NY//PE, PET//AL//NY//PE and so on.
Among them, small and light packaging can choose PET/PE, as a producer, the need to consider according to different capacity and bag type, careful evaluation, including PE puncture resistance, softness, tensile strength, thickness of the data, etc. Generally need to use NY, because NY toughness is stronger, can effectively avoid the nozzle position rupture, leakage.
Aluminum foil is also a common material in the suction bag, aluminum foil material performance is excellent, with opaque, silver, anti-luster, good barrier property, heat sealing, shielding optical activity, high/low temperature resistance, oil resistance, fragrance protection, no odor, softness and other characteristics, after more than three layers of film composite, printed packaging bags, can effectively extend the shelf life. It can also play the role of staying fragrance and is loved by consumers.
If the product of the bag is a product that needs cooking, then the inner layer of the package needs to use cooking materials, to reach 121 degrees Celsius high temperature cooking can also be used and eaten, then PET/PA/AL/RCPP is the best choice, PET is the outermost material for printing patterns, printing ink should also use cooking ink; PA is nylon, nylon itself can withstand high temperature; AL is aluminum foil, aluminum foil isolation, light resistance, preservation are excellent; RCPP is the innermost layer of heat sealing film, ordinary packaging bags using CPP material can be heat sealed, cooking packaging bags need to use RCPP, that is, cooking CPP.
Product advantage
The biggest advantage of mouthpiece bags over common forms of packaging is portability. The suction mouth bag can be easily put into a backpack or even a pocket, and can be reduced with the reduction of the contents, more convenient to carry.
Compared with plastic bottles with similar uses, the suction nozzle bag has a great advantage in price, can effectively save costs and improve the market competitiveness of the product.
Flexible packaging plastic printing effect is good, can meet the complex printing requirements, can print high definition, high precision, high saturation pattern, bring stronger visual impact.
Compared with ordinary self-standing bags or zipper bags, the nozzle bag is more sealed, easy to save, and easier to reuse.
