Problems solved by technology

However, the packaging bags with easy-to-tear openings have the following problems: 1. It will cause sharp corners at the easy-tear openings, which are easy to stick to people's hands; The content is spilled; 3. There is also the problem that it cannot be torn through the easy-to-tear opening, which leads to poor user experience of the easy-to-tear opening, and the easy-to-tear opening will reduce production efficiency

Embodiment Construction

[0015] Such as figure 1 As shown, an easy-to-tear packaging bag, the compound packaging film 1 is heat-sealed at the interface 2 that is folded in half, and one end of the opening at both ends is heat-sealed to form a bag. After the interior is filled with packaging materials, the other end is heat-sealed to form a package. , the composite packaging film 1 is composed of three layers through adhesives, the three layers are a PET layer located in the outer layer, an aluminum foil layer located in the middle, and a PE layer located in the inner layer.

[0016] The heat seal in the middle of the packaging bag (interface 2) no longer needs to be heat-sealed as in the prior art, and the easy-to-tear opening is no longer needed. The user can tear it at any place in the package. According to the different packaging, the user can choose to tear it open The location, the amount of tearing, and the tearing is linear.

[0017] This patent adopts the structure design of PET / AL / PE, the ou...

Abstract

The invention discloses a packaging bag easy to tear. The packaging bag easy to tear is formed by heat sealing a composite packaging film, the composite packaging film is formed by compounding three layers through an adhesive, and the three layers are a PET layer positioned on the outer layer, an aluminum foil layer positioned in the middle and a PE layer positioned on the inner layer. According to the packaging bag easy to tear, an easy-tearing opening punched in the packaging bag is not needed, equipment and the process for punching the easy-tearing opening are omitted, the packaging processis simplified, and the production efficiency is improved; the packaging film with good tearing performance is formed by bonding and compounding the three layers of films, and the barrier property andthe strength of the packaging bag can be ensured.

Description

technical field [0001] The invention relates to an easy-to-tear packaging bag, which belongs to the technical field of packaging bag production. Background technique [0002] In many cases, the packaging bag needs to be torn open by hand. In order to facilitate tearing, in the prior art, an easy-tear opening is made at the sealing edge, so that the package can be easily torn from the easy-tear opening by hand. However, the packaging bags with easy-to-tear openings have the following problems: 1. It will cause sharp corners at the easy-tear openings, which are easy to stick to people's hands; The content is spilled; 3. There is also the problem that it cannot be torn through the easy-tear opening, which leads to poor user experience of the easy-tear opening, and the easy-tear opening will reduce production efficiency. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides an easy-to-tear packaging bag. [0004] In order...
