1. There are two types of pointed bottom paper bag machines, one is LMD series (interrupt type) model, and the other is LSD series (point break type) model. The structure of the paper bags produced by these two models is the same. It can be made of flat paper bags with and without M side, and can also be made of triangular paper bags with two sides opening. Main uses, such as bread bags, biscuits bags, hamburger bags, meat sandwich bags, French fries bags, clothing bags, etc.

2.LMD series (interrupt type)) models, the bag mouth is cut in a zigzag shape, thicker paper needs to be cut with a thicker serrated knife, and thin paper can be cut with a finer serrated knife. The bag mouth is torn and formed at an oblique angle, and the tearing of each bag is not very regular, so this kind of bag mouth is not very beautiful. The cutting method adopts the breaking method, and the noise during cutting will be relatively large, but the price of the machine is relatively affordable, so this type of model is mostly bought by countries that are relatively backward in foreign countries, such as Africa, the Middle East and so on.

3.LSD series (point break type) models, the bag mouth is cut to form a dotted line section, and the bag mouth bevel is also broken according to the dotted line, each bag has the same section, and the bag mouth section is neat and beautiful. The cutting adopts the dotted line break method, the noise during operation is relatively small, and the bag making speed is faster, but the price is slightly higher than that of the LMD series (interrupt type), and most of the foreign countries and domestic countries currently buy this kind of machine type.

4.LMD series models are currently divided into 4 models, 2 models with different sizes of production ranges, 2 standard models and 2 simple matching models. The standard model is PLC control system, changing the cutting length size Touch screen input can track, position and cut printed materials.

5.LMD series simple matching models adopt frequency conversion speed regulation and mechanical control mode. To change the cutting length, the gears corresponding to the number of teeth need to be replaced, and the printed materials cannot be positioned and cut, but it can be connected to 2-color printing. Realize positioning and cutting.

6.The optional functions of the LMD series models are, two-color or four-color printing in one connection, but the simple matching model can only choose two-color printing in one, and the window in the middle of the paper bag (the window in the middle of this model may not be pressed The film is broken at the cutting position, and the tooth shape of the cross-section of the film is not clear), double-layer paper bag.

7.LSD series models are currently divided into 2 models, 2 models with different sizes of production range, using motion controller control system, changing cutting length size, folding bottom position, automatic number of points, automatic shutdown when material is exhausted, etc. It can be modified through touch screen input, with a high degree of automation, and can track, position and cut printed materials

8.LSD series models have many optional functions, such as two-color or four-color printing in one connection, the middle window of the paper bag can also be attached to the side window, the bottom folding line indentation and easy tearing line, special-shaped openings (arc, half Arc mouth), 38mm large tongue, double-sided tape on the bag mouth, punching holes on the bag surface, double-layer paper bag
