Material and characteristics of the self-standing nozzle bag

The nozzle stand-up bag is an important performance of the new development of plastic flexible packaging. The nozzle stand-up bag is based on the stand-up bag packaging with a rigid straw and a rotating lid, which can stand on its own, occupy an area, take convenience, low production, suitable for a variety of Category packaging, soy milk, jelly, beverages, jams and other food categories, shampoo, softener and other daily necessities packaging.

First, the characteristics of the self-supporting nozzle bag

The nozzle stand-up pouch has excellent printing power, clear graphics and text information, and brilliant color allocation. It not only promotes the product, attracts consumers' attention, but also promotes the brand level. The nozzle stand-up pouch has a fun-loving appearance. The simple packaging plan has the effect of extending the shelf life of the goods.

The self-contained suction bag has excellent refrigeration and sterilization, moisture-proof and moisture-proof, strong sealing, excellent pressure resistance, easy to break without being penetrated, easy to carry, fashionable and beautiful, strong flexibility, etc. , Widely used in a variety of packaging, bring fast and convenient life for everyone, has an important impact .

The nozzle self-supporting bag plays an important role in the opening and re-closing of food, and its function is equivalent to a bottle. However, considering the transportation, cost, and weight, it has advantages over the bottle. Therefore, it is more and more liked by the consumer market.

Second, the material structure of the nozzle self-supporting bag

Suction nozzle self-supporting bags are generally used to hold liquid and powder products. For the design structure, the following requirements are generally required to design the structure:

Three-dimensional: BOPA / LLDPE; bottom: BOPA / LLDPE

Three-dimensional: BOPA / reinforced BOPP / LLDPE; bottom: BOPA / LLDPE

Three-dimensional: PET / BOPA / reinforced BOPP / LLDPE; bottom; BOPA / LLDPE

In general, the self-supporting bag of the suction nozzle requires good structural barrier property, good impact resistance and pressure resistance, and the bottom needs good flexibility to facilitate processing. The use of BOPP material can increase the mechanical strength of the material and strengthen the barrier properties of the material. The use of PET also improves the material's water resistance and mechanical strength.
