Overview

The Open Top Discharge Spout Bag is an FIBC with a fully open, unskirted top and a fabric discharge spout sewn into the base panel. Also sold as an open fill spout discharge bag or open top spout bottom FIBC, the design is widely used across mining, quarrying, agriculture, cement, and building-materials supply chains. Buyers sourcing free-flowing granular solids — aggregate, grain, fertiliser, mineral powder — choose this configuration specifically because the open top imposes no restriction on filling rate, while the base spout gives the unloading side directional control: the spout can be tied off during storage and untied to feed a hopper, silo inlet, or conveyor at the destination.

Procurement managers evaluating this bag typically focus on two specification points that are easy to get wrong. First, spout length and diameter: a spout that is too short or too narrow for the destination equipment creates a bottleneck that defeats the purpose of the design, so specifying receiver dimensions before ordering is not optional. Second, fabric weight and loop count: a four-loop configuration distributes load evenly across a wider base spread than two-loop, which matters at high SWL on granular, high-bulk-density material. The absence of a top closure also means this bag should not be used for dusting or fine-powder materials where dust at the filling point is regulated — for those applications the Skirt Top or Spout Top variants are the correct choice.

India has been the dominant global source of woven-polypropylene FIBC for more than two decades. India Pack acts as a buyer's level-one procurement office in India: it sources from 10+ audited FIBC manufacturers, runs specification verification against the buyer's brief, provides production oversight, and handles export documentation. Over ten years and 25M+ bags supplied, the process is structured specifically to close the gap between a buyer's spec sheet and what arrives in container. India Pack does not manufacture bags; its margin is inside an all-inclusive, benchmarkable price, with no separate procurement fee to the buyer.

Which FIBC Type Do You Need?

Discharge spout FIBCs differ primarily at the top — whether filling is open, skirted, or through a spout. The table below maps common requirements to the right variant.

Your requirement Recommended
Maximum filling speed; dust at filling point not regulated Open Top Discharge Spout Bag (this page)
Dust control at filling required; open-top-style throughput still needed Skirt Top Discharge Spout Bag
Full dust seal at both fill and discharge; spout fill preferred Spout Top Discharge Spout Bag
Standard FIBC, no base discharge spout required Builders Bag
UN-certified hazardous goods in spout-discharge format UN Bag with Spout
Electrostatic dissipation required (Type C) Type C Bag with Label

Standard Variants

Standard circular woven body with four lift loops at the top and base discharge spout. Even load distribution across four attachment points.

Best for: Dense free-flowing granular solids (aggregate, mineral powder, cement) where balanced lifting is required.

Key spec: SWL [FILL]; body fabric GSM [FILL]

Two-Loop, Circular Body

Circular body with two lift loops. Suited to lighter-density materials or operations where a two-point lift is standard.

Best for: Agricultural grain, lighter fertiliser grades, operations with two-point forklift or hook handling.

Key spec: SWL [FILL]; body fabric GSM [FILL]

Four-Loop with Baffle

Internal cross-shaped baffle panels maintain a square footprint under load. Four lift loops. Base discharge spout.

Best for: Space-efficient palletising, racking, or container loading where bag bulge must be controlled.

Key spec: SWL [FILL]; baffle panel GSM matched to body fabric

Four-Loop with Liner

PE film liner inserted inside the woven body before filling. Liner prevents moisture ingress and product contact with the PP weave. Base discharge spout.

Best for: Hygroscopic materials (fertiliser, certain mineral powders) or any product requiring moisture barrier.

Industries and Applications

Mining and Quarrying

What's packed: Crushed aggregate, sand, gravel, mineral ore, quarry dust.

Why this bag: High-bulk-density material benefits from unrestricted filling; the discharge spout directs product onto conveyor belts or into hoppers without hand-cutting the bag. Four-loop construction is standard for heavy-aggregate SWL. Dust at the filling point is typically managed by the filling station itself, not the bag design.

Agriculture

What's packed: Grain (wheat, rice, maize), seeds, fertiliser granules.

Why this bag: Conveyor-fed grain elevators fill open-top FIBCs at speed without flow-rate penalties. The base spout enables discharge into grain storage bins or processing hoppers. Liner option protects hygroscopic materials. Suppliers with ISO 22000 certification are available [VERIFY per factory].

Chemicals

What's packed: Non-hazardous chemical granules, mineral powders, inorganic compounds.

Why this bag: Controlled discharge through the base spout reduces spillage and measures product input into processing equipment. For hazardous substances requiring static dissipation, the Type C variant should be evaluated instead — see Type C Bag with Label.

Cement and Building Materials

What's packed: Cement, dry mortar mix, sand, plaster.

Why this bag: Bulk cement logistics frequently use open-top fill at batching plants. The discharge spout delivers product directly into mixer inlets. Coated fabric is available for moisture-sensitive cement grades [VERIFY per factory].

Why source through India Pack

Full transparency — you always know your manufacturer

Once commercials are finalised, we disclose the details of the manufacturing facility producing your order. If you prefer a multi-facility portfolio strategy, we share the details of each qualified facility we've matched to your specifications.

The purchase order is raised directly in the name of the manufacturing facility — not India Pack — so there's no ambiguity about who is producing your goods. On request, we'll also arrange a direct introduction with a key contact at the facility.

We don't hide the factory behind us. You see exactly who you're buying from, and we earn our place by managing the relationship, the quality, and the documentation around it — not by controlling access to it.

Scale that works in your favour

We don't represent one buyer to one factory. India Pack brings a portfolio of buyers to a network of manufacturing facilities, and sitting in that position is what gives every buyer we work with an advantage they couldn't get alone.

It shows up first in capacity. At select facilities we hold dedicated production lines; across the rest of the network, the volume we place earns us priority. For you, that means your order isn't queued behind a factory's larger customers, and a busy season doesn't push your delivery date out.

It shows up in price. The combined volume we place gives us negotiating weight that most individual buyers can't match, so the quote you receive is competitive on a like-for-like specification — one you can hold directly against your existing suppliers and judge on the same terms.

It shows up most when something goes wrong. A factory settling a claim isn't weighing one order against the cost of fixing it; it's weighing the relationship with everything we bring them. That's the difference between a claim that drags and a claim that gets settled.

And because we're in these facilities every day, we know first-hand which one excels at a given specification, which to avoid for a particular material, and where quality actually holds. It's why we can match your bag to the right factory the first time.

The right bag, at the right weight — and the right price, every time you reorder

A bulk bag's cost is driven largely by how much fabric goes into it. Over-specify the weight and you pay for material you don't need; under-specify it and the bag fails in handling. We engineer each bag to the optimum fabric weight for your actual load and handling conditions — strong enough to perform reliably, without the cost of over-built material you'll never use.

We benchmark that specification across our facility network so your first quote is competitive — sharp because the bag is specified correctly, not because it's cut short. And we keep benchmarking on every reorder. Raw material prices move, and so should your price — down as well as up. You won't find a low opening quote that quietly drifts upward once the relationship is established. The price stays honest because we keep checking it against the market, order after order.

Transparent pricing, no separate fees

You don't pay India Pack a separate service fee or commission. We act as your level-one procurement office in India, and our pricing is all-inclusive — so you can compare our quote directly against your existing suppliers, like for like. What you save is in the price, not in a separate line item.

Order flexibility — build a container on your terms

You don't have to place a full-container order all at once, or commit to a single bag specification. Within an order you can mix specifications, and we select facilities capable of producing the range you need — so a single container can carry the mix your operation actually requires.

You can also build a container over time. Place orders as your requirement firms up, and we'll keep the container open — with the price of each order locked at the point you place it — until the load is complete. You're not forced to forecast a full container in one go or accept a price that moves while you wait.

Two practical limits keep this clean: we hold a container open for up to 20-25 days from your first order, and dispatch lead times begin once the container composition is final and the load is full. For procurement teams used to committing to full single-spec containers upfront, that flexibility removes both the forecasting pressure and the risk of over-ordering.

Factory access without factory risk

India Pack maintains active sourcing relationships with 10+ FIBC manufacturers across India. When a factory hits a capacity constraint or a quality issue, we give you the option to switch production without interrupting your supply. You don't restart vendor qualification from scratch — we carry that burden for you.

Documentation managed end to end

We manage the complete export documentation set — commercial invoice, packing list, certificate of analysis, SWL test certificates, packing inspection report, and any third-party inspection reports — so your import clearance proceeds without delays or amendment requests. We have supported buyers in Europe, USA, Canada, Middle East, Australia, and New Zealand across food processing, chemicals, construction and mineral trading.

Send us your specs and we'll come back with supplier options and a quote. Don't have them finalised? Tell us what you're packing and where it's going — we'll help you build the right specification. Distributors or end-users, you bring the requirement and we handle the supply.

Frequently Asked Questions

We are a sourcing partner, not a factory. We connect you to a network of audited Indian manufacturers, match each order to the right plant, and manage specification, quality, and shipment on the ground.

Yes. For custom branding, we review your artwork files for resolution, print alignment, and fit to the bag geometry. If you don't have technical drawings or layouts ready, our team drafts the bag specification sheets and print-ready layouts for your approval.

We treat your designs, artwork, and intellectual property as confidential. Confidentiality terms are enforced down the supply chain with our manufacturing partners in India.

We provide free prototype samples of standard or readily available fabric specifications for your evaluation and physical testing, shipped through international couriers such as DHL, FedEx, UPS, DPD, or Interparcel.

We provide up to 2 samples completely free of cost, with courier included. Beyond that, additional samples remain free of charge and you cover only the courier.

Standard manufacturing lead time for an initial order is 5–8 weeks from final artwork and specification sign-off, with advance payment or LC opening. Repeat orders with identical specifications often run faster, as plants pre-schedule production blocks and keep printing plates ready for mounting.

Bags are hydraulically compressed, wrapped in moisture-resistant, UV-stabilised PP sheets, and bound with high-tensile bands for long transit. Each bale carries multi-sided, waterproof labels showing your PO number, bag specifications, quantities, and weights.

Average full-container transit times are 35–45 days to Europe (via the Cape), 30–40 days to the US East Coast, 35– 45 days to the US West Coast and New Zealand, and 45–55 days to Latin America. Actual schedules vary with seasonal carrier routing and whether the load is FCL or LCL. We keep you posted about the status of the shipment

Air blowing and suction remove loose PP fragments and dust using filtered, oil-free compressed air and vacuum extraction. Light-table inspection checks every seam against backlighting to catch dropped stitches, pinholes, or weave defects. if specified we run Bags though Metal detection to confirm no embedded needle fragments or metallic tools remain.

In case of a claim we are your representative to the company, We review production records alongside your photos or videos to identify the root cause. If a manufacturing defect is verified, we issue a credit or replacement and update factory protocols to prevent recurrence.

Our facilities run in-house load tests on every production run. Certified test reports and label proofs are sent to you for verification and approval before dispatch. We share pre production bag photos to confirm that bags are being mass produced as per your specification. This would include Safety Label, Print artwork, Pre production Print Panel, Printing, Bag dimensions, accesories

We provide high-strength overlock and safety stitching, along with double-needle stitching options based on your application and handling needs. Because stitching directly dictates the bag's Safe Working Load (SWL), every seam meets industrial safety standards.

Yes, we supply both J-fold and Butterfly-fold edge construction depending on your facility's filling infrastructure.

We offer single, double, and triple sift-proofing, using high-density filler cords and non-woven felt layers sewn directly into the seams to plug needle holes. For ultra-fine or hygroscopic materials, we can integrate heavy-duty polyethylene (PE) internal liners for dust-proof and moisture-proof security.

Yes, we source food-grade and pharmaceutical-grade big bags produced in BRCGS-certified cleanroom facilities that meet US FDA and European standards. These bags undergo pest control, metal detection, and hygiene audits to support contamination control for sensitive ingredients.

Type A bags provide no static protection and suit non-flammable materials. Type B bags prevent propagating brush discharges but are not rated for flammable solvent or gas atmospheres. Type C (conductive) bags use interconnected conductive threads and must be grounded during filling and discharge. Type D (dissipative) bags safely release charge into the air without a ground connection.

Yes, we offer full design flexibility including duffel tops for easy manual filling, open tops, and conical discharge spouts for sticky or sluggish materials. Our technical team matches the bag's openings to your filling and discharging equipment.

Our standard loop colours are white, blue, and black. We can provide other colours free of charge if currently in stock. For custom, Pantone-specific colours, a minimum order quantity (MOQ) of 2 MT applies.

A B-Lock (or cord lock) is a heavy-duty plastic or metal locking device attached to the tie-strings of a bag's spout, usually the discharge spout. It lets operators lock the spout closed and adjust or release it during emptying without untying tight knots.

A Hose Slider is a closure mechanism that regulates or completely stops material flow through the discharge spout. It works by sliding a rigid bar or collar over the spout to pinch it shut, giving operators precise control when partially emptying a bag.

We supply to your required safety factor. Industry standard is 5:1 for single-trip bags and 6:1 for multi-trip bags, with UN-certified bags for dangerous goods built to a 6:1 minimum.

Single-trip bags are designed for one filling and discharge cycle and are the most cost-efficient choice for one-way shipments. Multi-trip bags use heavier GSM fabric and a higher safety factor for repeated reuse. We match the construction to how the bag will be used.

Yes. We add UV stabilisers to the fabric for bags stored or handled outdoors, rated to 200 KLY to 350 KLY.

Baffle bags have internal fabric panels at the corners that hold the bag's square shape when filled, so it doesn't bulge. That lets you load more product per pallet and stack more stably in containers and warehouses. See our Baffle FIBC page for full specifications.

Coated (laminated) fabric adds a moisture and sift barrier and suits fine or hygroscopic powders. Uncoated fabric allows the bag to breathe, which suits products that need ventilation such as some agricultural goods. We recommend based on your product.

We offer loose, form-fit, and tubular polyethylene liners, EVOH liners, plus aluminium-foil liners for moisture- or oxygen-sensitive products. The liner type depends on your product's barrier needs.

The most common sizes are A4 (full-page documents and manifests) and A5 (smaller labels and barcodes). Custom sizes can also be made. Two closure options are available:
  • Standard Flap: a top or side opening with an overlapping flap to keep out dust.
  • Ziplock (resealable): maximum protection against rain, moisture, and grime.

The minimum order quantity for coloured fabric is 3 MT. A specific Pantone colour number is always required for production.

We produce woven PP fabric across a range of weights to match your strength and cost needs, from 55 GSM to 240 GSM additional coating 30 gsm

Yes. We source BOPP-laminated woven bags with high-definition print for consumer-facing and retail-grade packaging, giving sharp graphics and a moisture barrier in one structure. MOQ's apply
