The purpose of the pre-opened bag making machine 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, 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.

New application of our pre-opened bag on roll in supermarket

The new application of our current pre-opened bag on roll has come true in the supermarket.As we know,usually in the supermarket,the bag what we used is on roll but actually they are only flat end bag on roll,the bag top is closed when it was made by the bag making machine.

But customer sometimes found that the bag is not very easy to open the bag top when they need to use it to pack the fruit or vegetable,so we have a new idea to use such pre-opened bag to replace the normal bag,because the pre-opened bag is one side mouth open already.It’s very easy to be tear off by customer one by one and directly fill the fruit into the bag without opening the bag top by manual.

Also the bag thickness can be similar as normal HDPE bag,so this new type bag which made by our pre-opened bag making machine is a new choice for the supermarket,fruit and vegetable shop.
