We supply sewing machines for the closure of open mouth polypropylene sacks.
The characteristics of polypropylene give these sacks their great strength even in low thicknesses. These sacks are not heat sealed but sewn and reinforced with thread.
There are various manufacturing possibilities:
- Interior lining. This has a film of polyethylene stuck to the inside of the sack making it impermeable and airtight and giving it greater strength to avoid any leaks.
- Interior polyethylene sack. The product is protected by two independent layers with the additional security of having independent sealing.
- Valve fill system. We can adapt to all types of filling machines with valves of any width.
Suitable for a wide range of uses in the following industries:
- Agricultural pesticides
- Basic pharmaceuticals
- Animal feedstuff
Sacks of different sizes and characteristics are available in stock for immediate dispatch. Bespoke manufacturing is also available.
