90-120pcs/min PP Woven Block Bottom Valve Sacks Making Machine For
Putty Power Bag
Valve sacks or valve bags provide the perfect packaging solution
for high speed filling of powdered products whilst maintaining a
dust free working environment.
Available in Polythene, Paper or Woven Polypropylene, valve sacks
can be used for many products from dyes to foodstuffs. Once filled
they form a solid block which makes them easily stackable on the
pallet.

| 4. Space requirements |
| Equipment Size | L*W*H: 12 m×7.5 m×3m |
| Ground strength | The installation place must keep the ground flat and have enough
bearing pressure. The foundation should not conduct vibrations
generated during operation. The permissible ground load must not be
lower than 25000 N/m2 |
| Environment temperature | The equipment should not be installed outdoors! The ambient
temperature in production halls and warehouses must be between 18
°C and 40 °C! |
2.Cooling water requirements
To minimize water consumption, Seller recommends a closed cooling
water system with an air-cooled water chiller.
The water used for filling the system and for the production
process (if any) has to be free from impurities
(corrosive particles, suspended matter, etc.). Furthermore, it has
to meet the following requirements:
The process water must be free from:
- visible impurities such as suspended or turbid matter
- biological impurities such as bacteria, algae, or mucilage
- fats, oils, or other aliphatic or aromatic compounds
- fluorinated or halogenated substances such as refrigerant R131 or
the like
- or other substances which may affect the material to be
pelletized or the components of the line
