Cement Sack Making Machine main features:
1. Compact
One set cement sack making machine can replace five traditional bag making machines perfectly. Machine size: 16.65 x 2.9 x 2.2m, covers an area less than 50M2.
2. Easy Operation
With parameter pre-setting, frequency and speed adjustment technology, operation is easier and production is more stable.
3. Environment Friendly
Low noise, without any pollution during the whole production process (without waste water, waste gas and waste dregs).
4. Low Cost
Power and labor saving, total power 10KW only and 3 workers/shift.
5. High Efficiency
Automatically finish the entire processes of material-feeding, bag-forming, compound, folding, printing, perforating and cutting, less hands, more effective.
6. Multi-function
Flat bags and gusseted bags, sewn bags and pasted bags are can be manufactured with the cement sack making machine.

After-Sales Service:
Guarantee:12-18 months ( based on different area), and our engineer will help to set up the set of cement sack making machine, and train the workers.

Others:

OEM and ODM are accepted.

Paper Yarn Cement Sack Features:
1. High Aging Resistance
Two layers sack paper prevents the light and ultraviolet radiation out of the paper yarn bag, which helps the bag to keep a strong aging resistance for a long time, and the strength of bag can be last longer.

2. High Strength
Paper yarn cement sack is wrapped circle by circle without break points, it forms a whole yarn net without centre joint, which reinforces the bag strength.

3. High-temperature Resistance
Burning point of the sack paper is 183℃, and the yarn can resist the high temperature of 180℃ under no water condition, so the paper yarn bag can maintain strength under high temperature. For example the bitumen bag and zironium silicate bag are filled contents of teperature of 130 ℃ , but keep the same strength.

4. Air Pervious and Moisture Proof
When manufacture the paper yarn cement sack, the yarn netting is pressed into PVA film which between the two pieces of paper, it takes the effect of binder and moisture proof. And at the same time, there are many tiny holes during the production of rolling plasmogen which help to release air freely.

5. Stack without Slipping
The winding yarns of three directions form the 15° angle and make up many triangles, which strengthens the friction force between the sacks. Take 500*800MM bag for example, it can stack 40 bags, about 4 meters high.

6. Environmental Friendly
After recycling, the paper form pulp, the raw material of paper, and in the water of 85℃, the yarn will dissolve into PVA which is necessary for paper production. Also, the ink printed on the paper is water-based ink, a non-toxic and environment friendly ink. In all, the used bags can be recycled and without environmental pollution.
