Characteristics of four-side sealing bags

 Four-side seal bags are cheap and widely used, but they are prone to many problems during transportation and storage. For example, when the bags are stored, the packaging bags are prone to explosion due to the overlap of goods. Due to improper extraction during transportation, the packaging bag can easily fall off and break. During use, the four-side sealing bag is processed so that it is not easy to tear, so when it is not easy to tear, always tear it hard. For example, the packaging bag is not strong enough and is easy to tear the entire package. In order to improve the strength of packaging bags in the market, processes such as improving packaging materials or increasing thickness are often used, so let’s learn about the characteristics of four-side sealing bags!

   The purpose of the four-side sealing bag is to solve the shortcomings of the above technology and provide a four-side packaging bag with simple design, reasonable structure, easy processing, safety and durability. In order to solve the above problems, the utility model has a four-side sealing bag body that is closed on all four sides, the top of the bag is sealed to form a sealing tongue, and the two sides of the bag have folding walls, fold lines and opposite edges. The folded walls are symmetrically distributed along the fold line, and the surface boundary is located between the folded walls and the surface of the pocket.

   Furthermore, the sealing tongue has an easy-to-tear line and an easy-to-tear part, and the easy-to-tear part is located at one end of the easy-to-tear line.

   In addition, the corresponding pocket also has concave and convex lock buttons and a pair of sealing holes. The bump lock button pictured here is located on a folded wall sill, under a line that easily tears. The pair of sealing holes are respectively provided on one of the folding walls on both sides, located at the bottom of the sealing tongue and at one end of the folding wall seal.

   In addition, the sealing hole is bonded to the connecting wall through heat sealing. Furthermore, an included angle is formed between the half connecting walls, and the included angle is 25-80°. Furthermore, the narrative angle is 60 degrees. In addition, the reinforced sealing surface is located between the sealing tongue and the top of the bag, and the reinforced sealing surface is arc-shaped. In addition, one end of the reinforced seal extends to one end of the folded wall seal, and the other end extends between the folded wall and the face boundary.

   The advantages of the four-side sealing bag are: the bag has folding wall sealing and reinforced sealing surface, good sealing effect, simple structure, the sealing hole is installed on both sides of the folding wall, the location is reasonable, the structure is simple, the folding wall and sealing tongue structure is simple, the design of this bag Simple, reasonable structure, convenient processing, safe and durable, and good sealing effect.
