INQUIRY

The bag below is our another new design on our pre-open bag making machine,it has 1 sealing line,2 perforating line.

About the two perforating lines,they are on bag top and bottom,one is for normal pre-open inline when we do bag making,another is pre-cut perforating line for bag easy open when we finished packing item inside the bag.Also this pre-cut perforating line for bag easy open have two design,one is full bag width perforating,another is 60%-80% or more or less open.This can be adjusted by switching the perforating blade width(Double perforating blade picture as below too).

If we come to compare these two bag as above first,we can find that the difference of the two bag is the perforation line,the left bag has two perforation line but the right one has only one,or we say the left bag has one more pre-cut line on our pre-open bag on-a-roll making machine.

The first line which both bags have is just for the pre-open rubber roller to make pre-open on the bag top,so each bag has such same perforation line,and it’s necessary in our pre-open bag machine,can not be missed.

About the extra line below the main perforation line which the left bag has,actually this line is made by one more pre-cut perforation blade on our pre-opened bag making machine,by this extra pre-cut line,we can easily open the bag after we seal the bag and want to use.One more thing is this extra pre-cut easy open perforation line can not be only 100% full dotted cutting,but also can be less such as 50%-80% open,this will not only help to make sure the bag sealing quality,loading ability,also can make open easily too compare to full open.And this less width pre-cut perforation line is made accord to our new technology:try to fix some less blades onto the perforating blade holder.

Performance And Characterlstics:

This pre-opened bag making machine/pre-opened bag on-a-roll making machine is our newest design machine,it has much functions as photoelectric automatic tracking microcomputer length setting,highlimit stopping,automatic counting,automatic alarm on reaching the set value,high compensation accuracy with such characteristics as neat bags,little error and high automatic of whole machine,so it is a kind of ideal equipment for producing pre-open bag to match the line of autobag,titan, sharp packing machine.

Technical implementation elements:

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.
