What are PP Woven Bags made of?
PP woven bags — also called polypropylene woven bags or poly woven sacks — are made from 100% polypropylene (PP) resin. PP granules are extruded into flat tapes, oriented (stretched) for tensile strength, and then woven on circular looms into tubular fabric in an interlocked warp-and-weft pattern. This woven fabric is cut to size, printed (if specified), and stitched or sealed into finished bags. Polypropylene is lightweight, chemically resistant, moisture-tolerant, and 100% recyclable as resin code #5.
What is the difference between laminated and unlaminated PP woven bags?
Laminated PP woven bags have a PP or BOPP film bonded to the outer surface — providing a moisture barrier, dust resistance, and a smooth surface for high-quality multi-colour printing. They are ideal for PP woven cement bags, sugar bags, flour, and chemical packing. Unlaminated PP woven bags (plain woven polypropylene sacks) are breathable and more economical — ideal for PP woven fertiliser bags, grain, sand, and agricultural produce. Both laminated and unlaminated variants are 100% polypropylene and fully recyclable.
What industries use PP woven bags?
PP woven bags and polypropylene woven sacks are used across agriculture (rice, wheat, fertilisers — PP woven fertiliser bags, PP woven bags for rice packing), construction (PP woven cement bags, sand, gypsum), food processing (PP woven bags for sugar packing, flour, salt, spices), chemicals (polymer granules, resins — PP woven bags for chemical packing), animal feed, retail, logistics, aquaculture, and mining. Their strength, light weight, and customisability make them suitable for any dry bulk product from 5 kg to 100 kg per bag.
Can PP woven bags be customised?
Yes. Aeroflex Neu Limited offers complete customisation for custom PP woven bags India-wide and for export: bag width (45–148 cm tubular), length (any), fabric GSM (50–140), colour (white, transparent, or any custom colour PP tape), mesh count (10×10 to 14×14), top finish (heat-cut, zig-zag, hemmed, valve), gusset (side or bottom — any depth), lamination (PP or BOPP film), UV stabilisation, six-colour flexographic printing (printed PP woven bags), micro-perforation, and inner PE liner. Minimum order quantities apply — contact us with your full specification for a quote.
What is a PP woven valve bag and when should I use it?
A PP woven valve bag is a polypropylene woven sack with a self-sealing or fold-closed valve at one corner, through which product is filled via a nozzle on an automated filling line. When the bag reaches its target fill weight, the nozzle is withdrawn and the valve closes — sealing the product without heat sealing or stitching. PP woven valve bags are the standard format for laminated PP woven bags for cement (OPC and white cement), dry plaster, gypsum, and powdered chemicals on rotary or inline filling machines.
What is the GSM of PP woven bags — which GSM should I choose?
PP woven bags are manufactured from 50 GSM to 140 GSM. As a guide: 50–60 GSM for retail and shopping bags (up to 10 kg); 60–75 GSM for PP woven bags for rice packing and light food grains (10–20 kg); 75–90 GSM for PP woven fertiliser bags and cement bags (20–35 kg); 90–110 GSM for 50 kg PP woven cement bags and chemical packing; 110–120 GSM for 50–75 kg industrial bags; 120–140 GSM for heavy-duty bulk sacks up to 100 kg. Aeroflex Neu Limited can produce any GSM in this range with full customisation.
What is the price of PP woven bags per kg or per piece in India?
PP woven bags price per kg and price per piece in India varies depending on fabric GSM, bag dimensions, lamination (laminated PP woven bags cost more than unlaminated), number of print colours (printed PP woven bags), and order quantity. Wholesale PP woven bags in large volumes attract lower per-unit pricing. PP resin market price also affects final bag price.

Are PP woven bags recyclable and eco-friendly?
Yes. PP woven bags — whether laminated or unlaminated — are made from 100% polypropylene, classified as recyclable plastic resin code #5. Used polypropylene woven bags and sacks can be shredded and reprocessed into PP granules for reuse in manufacturing. Unlike multi-layer composite packaging, PP woven bags (especially unlaminated variants) are easy to recycle in standard plastic recycling streams. Aeroflex Neu Limited also operates a minimal-wastage manufacturing process, reducing the environmental footprint of every batch of custom PP woven bags produced.
What is the difference between PP woven bags and non-woven bags?
PP woven bags (polypropylene woven sacks) are made by weaving flat PP tapes in a warp-and-weft pattern on circular looms — producing a high-strength fabric capable of carrying 5–100 kg. Non-woven bags are made by thermally or chemically bonding PP fibres without weaving — producing a lighter, softer material typically used for retail shopping bags under 20 kg. PP woven bags have significantly higher tensile strength, load capacity, and durability compared to non-woven bags, making them the choice for industrial bulk packaging.
Where is Aeroflex Neu Limited's PP woven bags manufacturing plant located?
