B700 Non Woven Bag Making Machine

Choose the machine from the bags
Before discussing what machines are needed, you need to have some basic understanding from the point of view for the non-woven bags you want to produce. This can also be helpful if you need to purchase non-woven bags.

Classification of bag types
Regarding the bag types of the non-woven bag, there are with different names in different countries and regions, and the classification can be based on the usage, such as shoe bags, nursery bags, garment bags, promotional bags, etc.; if discussing the models and specifications of the corresponding bag making machine, it is recommended to classify according to the appearance of the bags. The following five types of bags are the most common on the market, and thye are the first to know when purchasing a machine:

W-cut bag (t-shirt or u-cut, or vest bag)
The most popular type of polythene bags, instead of polythene, here it's made of polypropylene non woven fabric. Simple and practical, low cost, it is the most commonly used bag type in the banned country as well.

D-cut bag(or flat bag)
The same very common bag type is often used as a supplement to w-cut. In the banned countries, these two types of bags are conservatively estimated to account for more than 80% of the entire market.

Drawstring bag(shoes bag)
Usually used for the internal packaging of shoes, so it is also called shoes bag.

Handle bag(loop handle bag)
In fact, all bags with handles including the handle box bag below(no.5) can be called handle bags. But practically we call it "handle bag" only when it's not handle box bag.

Handle box bag
A handle bag with both bottom and side gusset, we call it handle box bag.

Materials
Non-woven bag making machines can handle a variety of materials, the most common of which is: Spunbond non-wovens . We are only discussing the spunbond non-wovens here, such as the water-spun non-wovens, which require a custom-made bag making machine.

Thickness
The unit of measure is gsm(grams per square meter), which is how many grams per square meter. The range of fabric thickness affects the choice of machine.
The theoretically producible fabric thickness range for most machines on the market is the same 30-120 gsm, but the "comfort range" varies from different configurations. A common configuration is 300mm ultrasonic with a comfort range of 50-120gsm.Only the fabric needs to use most of the time is more than 80gsm, 300mm ultrasonic is recommended. If you produce thinner fabrics most of the time, you can choose 153mm ultrasonic mould, the comfort range is about 20-50gsm.

Ii. Choose the bag making machine

Bag type corresponding bag making machine
Bag type corresponding machine capacity

And here is the corresponding capacity to those schemes.
[1] The machine can only produce one bag type at the same time. For capacity calculation and its influencing factors, check here.
[2] A single machine can match multiple manual punches, and 0.8 is a capacity for configuring a manual punch, if 2sets, 1.6million pcs.
[3] A single machine can match multiple hanlde sealing machines, and 0.3 is the capacity when configuring a single 4-point sealing, if 2sets, 0.6million pcs.

Iii. Other auxiliary machines
In the process of producing bags, other machines are needed to assist in the production of bag making machines:

Air compressor (required)
Necessary air source, select the corresponding power according to the number of models and machines.
Air compressors are divided into piston and screw, which are mainly reflected in the difference between the purchase cost and the use cost. The screw type is expensive, but durable and energy efficient.

Manual bag making machine (recommended)
There are two kinds of lace machines and spot welders, which are corresponding to edge welding and handle welding. Usually used in the following two situations:

Slitting machine (optional)
Fabric suppliers have a long supply and shipping cycle. In the face of changes in order specifications, or when the handle reel needs to be made by yourself, a slitting machine is required.

Stabilizer (optional)
In some countries, the voltage supply is unstable. It is recommended to purchase a voltage regulator to protect the stable operation of the machine.
The regulator is normally depleted. A general regulator, in an environment where the voltage change is not stable, it may take a 1-2 year to replace it.

Generator (optional)
Considering that the construction of grid facilities in individual countries is not perfect, or the power supply is insufficient, it will face more frequent power outages. In order to guarantee orderly production, temporary power supply can be provided by the generator.
