Background technique of pre-open bag on-a-roll

Background technique of pre-open bag on-a-roll:
With the rapid development of the domestic industry, the demand for packaging is increasing, making it difficult for many companies to deal with the last process, namely packaging, in a unit of time. The traditional method is to require workers to open a single plastic bag, and then Manually filling items and then sealing, manual operation is easy to cause material loss and time-consuming and labor-intensive.

Technical implementation elements:
The purpose of the utility model is to solve the above problems and shortcomings, to provide a single-sided pre-opened bag suitable for automatic feeding, automatic heat sealing and automatic cutting, which can be used with the machine, so as to save labor costs and improve work efficiency.
The purpose of the utility model is achieved through the following technical solutions: a single-sided pre-opened bag on-a-roll, including several plastic bags, one side zigzag point connection between the plastic bag and the plastic bag, and the other side between the plastic bag and the plastic bag. With opening.
Further, the single-sided pre-opened bag on-a-roll includes several plastic bags, one side between the plastic bags and the plastic bags is zigzag point connection, the other side is integrally connected with the upper and lower ends of the plastic bag and the plastic bag, and the middle is open. The one-piece connection length is 5mm.
Because the utility model adopts the above-mentioned packaging structure, the assembly line directly puts the articles into the plastic bag, and the machine automatically recognizes and completes the feeding action, performs heat sealing and cuts off the connection with the previous plastic bag. It can save post operators, and complete the packaging process by mechanical automation, improve work efficiency, and realize large-scale fully automated operations.
