What type of packaging is used for coffee? I just want to say too much. If you distinguish from the shape, the common packaging types are as follows:
Coffee stick pack, drip coffee bag, 3 side seal, 4 side seal. These types are all small-dose packaging, easy to carry. So how do these types of packing coffee complete?
1. Coffee stick pack, 3 side seal and 4 side seal bag
Although these three packaging types are different, they can be completed by the same type of packaging equipment, but different bag-making methods need to be replaced. One of the more commonly used is the small vertical packaging machine, its packaging process is:
The film roll placed on the supporting device is wound around the guide roller group tensioning device, after detecting the position of the trademark pattern on the packaging film by the photoelectric detection and control device, it is rolled into a cylinder by a former and wrapped on the surface of the tube. First use a longitudinal heat sealer to longitudinally heat seal the film at the interface of the cylinder to obtain a sealed tube, then the cylindrical film is moved to the transverse heat sealer for transverse sealing to form a bag tube. The measuring device fills the measured coffee into the bag through the filling tube, then it is heat-sealed by a transverse heat sealer and cut at the middle position to form a bag unit and at the same time form the bottom of the next bag.( If it is a 4 side sealing bag, the two sides will be sealed first, then the bottom will be sealed, and the top will be sealed after the filling is completed)
2. Drip coffee bag
This is a very popular packaging method now, and the packaging process is completed by a special drip coffee bag packing machine.
This is a double-layer packaging, the coffee is packed in an inner bag made of filter paper material, and then the inner bag is clamped by the combination of high-quality pneumatic components and PLC control. It is transported to the outer bag former through a stable mechanical structure, and the angle, opening time, and opening size are adjusted to ensure that the inner bag enters the outer bag accurately. The outer bag usually uses composite packaging materials.
