1 Raw material delivery equipment

The delivery equipment delivers the raw material from the roll to the line. Delivery is done automatically. The equipment has an automatic stop system. A 1.5 kW motor is installed on the equipment.

2 Equipment for folding into a special shape

In the equipment for folding into a special shape, the raw material from the roll is folded at both ends and glued. At the next stage, the raw material is folded into two layers.

3 Multifunctional shaping equipment

This equipment forms the bottom and sides of the bag. The material passes through a special loop to form the bottom part. The equipment leaves a special mark on the material to form the side part of the bag. In this equipment, bags can be formed in a simple or box shape. A pneumatic device is installed so that the material moves uniformly through the equipment.

4 Tape holder cutting and gluing equipment

In this equipment, the tape-shaped material is cut into holders of the required size. The cut holders are automatically glued to the bags. The length of the handles can be changed according to the requirement.

5 Equipment for gluing and cutting the sides of bags

In the first part of the equipment, semi-finished packages are glued by heating the side parts. In the second part, the packages are cut to the required size.

6 Bag opening device

In this equipment, the holder is opened by punching the bag. The equipment cuts D- and V-shaped holders. A tape holder is not required when using this equipment.

7 Flexographic printing equipment

Specially designed for printing words and trade marks on polypropylene bags, paper bags. The equipment has a simple 2-color structure, easy operation and maintenance, high precision automatic counter and photoelectric function. The equipment has a production capacity of 1500-3500 pieces per hour.
