Woven Sack Bags with Plastic Liners
Bulk Packaging
Dhanshri Polypack offers woven bulk sack bags with internal plastic liners that provide effective containment and transportation of powders, grains and other bulk materials.
Introduction to Woven Sacks with Liners
Woven sack bags refer to large bulk bags made from thick woven polypropylene or polyethylene fabric. They are often lined with internal plastic liners that provide the following key benefits:
- Prevent leakage of fine powders through the fabric pores
- Provide an additional layer of strength and abrasion resistance
- Protect hygroscopic materials from absorbing moisture
- Allow use of breathable fabric while ensuring complete containment
- Offer chemical and corrosion resistance to contents
The combination of a strong woven outer fabric and internal liner offers optimal packaging performance for bulk transportation.
Types of Plastic Liners
We offer woven sacks with following liner options:
- PE liners – Food safe and chemically resistant
- EVOH liners – High barrier against gases and moisture
- Foil liners – Excellent barrier for chemicals and solvents
- Baffled liners – For free flowing fine powders
- Anti-static liners – For static sensitive materials
The dimension of the plastic liner pouch matches that of the outer woven sack.
Key Applications of Sacks with Liners
Woven sacks with internal plastic liners are ideal for:
- Foods: Flours, grains, cereals, pulses, salt
- Industrial chemicals: Pigments, powders, granules
- Pharmaceuticals: Tablets, capsules, granulated formulations
- Agriculture: Seeds, animal feed, fertilizers
- Minerals and ores
The liners provide secure containment even with rough handling during shipping.
