Overview

The U Panel Bag with Liner is an FIBC sewn from two U-shaped fabric panels — body and base formed as a single piece on each panel — with an internal liner fitted inside the outer woven shell before filling. Also specified as a U-panel FIBC with liner or two-panel bag with liner, the design is used across food ingredients, agriculture, bulk chemicals, and pharmaceutical raw materials. The reduced side-seam count of U-panel construction matters where seam integrity under sustained dynamic load is a procurement specification — fewer seam lines means fewer potential failure points compared to a standard four-panel bag at the same SWL. The liner provides a second, independent barrier: it physically separates the contents from the PP weave and from ambient moisture, without relying on coating of the outer fabric.

Procurement managers evaluating this bag typically audit two specification areas where errors are costly. First, liner compatibility: the liner material — PE film, food-grade PE, woven PP inner liner, or a specialist moisture-barrier film — must be chemically compatible with the specific fill material. Incompatible liner material can contaminate the product or degrade under contact; this is confirmed between buyer, India Pack, and the supplying factory before production, not assumed. Second, liner integration at discharge: a loose-insert liner tied at the top behaves differently at unloading than a form-fit liner with a discharge pass-through — specifying the unloading process determines which arrangement is correct. Buyers sourcing food ingredients additionally need to confirm whether the supplying factory holds ISO 22000 or equivalent, since the food-grade liner claim attaches to the factory's certification, not to the liner specification alone.

India Pack acts as a buyer's level-one procurement office in India, sourcing from 10+ audited FIBC manufacturers, running specification verification against the buyer's brief, and handling export documentation. Over ten years and 25M+ bags supplied, the process is structured to close the gap between a buyer's spec sheet and what arrives in container. India Pack sources; it does not manufacture. Its margin is inside an all-inclusive, benchmarkable price, with no separate procurement fee to the buyer.

Standard Variants

PE Film Liner — Open Top

U-panel body with a PE film loose-insert or form-fit liner, open top closure. Liner is tied at the neck after filling; outer top closed by tie cord or drawstring.

Best for: Hygroscopic powders, fertiliser grades, mineral compounds requiring moisture exclusion but not direct food-grade contact certification.

Key spec: SWL [FILL]; liner film micron [FILL]; body fabric GSM [FILL]

Food-Grade PE Liner — Spout Top / Spout Discharge

U-panel body with a food-grade PE liner, spout top fill, and spout discharge bottom. Liner sealed to both spouts for full product isolation.

Best for: Food ingredients, starch, sugar, grain, seed — applications where both the liner material and the supplying factory's food certification are specified. [VERIFY per factory]

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

Woven PP Inner Liner

Secondary woven polypropylene liner sewn inside the outer U-panel body. Provides a fabric-on-fabric barrier that can carry its own print or labelling; lighter moisture protection than PE film but superior abrasion resistance at the liner surface.

Best for: Agricultural seeds and granular chemicals where product contact with the primary weave must be prevented but PE film barrier is not required.

Key spec: SWL [FILL]; inner liner GSM [FILL]; outer body GSM [FILL]

Moisture-Barrier Liner — Skirt Top

U-panel body with a specialist moisture-barrier film liner (typically laminated or multi-layer PE) and a skirt top for dust containment at fill. For contents where standard PE film micron is insufficient for the filling-environment humidity or the product's hygroscopic sensitivity.

Best for: High-hygroscopic-sensitivity chemicals, pharmaceutical excipients, fine powders filled in high-humidity environments. [VERIFY per factory]

Key spec: SWL [FILL]; liner specification [FILL — confirm film grade with factory]; body GSM [FILL]

Industries and Applications

Food and Food Ingredients

What's packed: Starch, sugar, flour, dried food powders, grain, seed.

Why this bag: Food-grade PE liner prevents the product from contacting the PP weave and provides a sealed hygiene barrier. U-panel construction avoids the additional seam lines of a four-panel body — a factor some food auditors note in production-hygiene assessments. Suppliers with ISO 22000 or equivalent food certification are available in the India Pack network [VERIFY per factory].

Agriculture

What's packed: Seeds, grain, agricultural powders, plant-nutrition granules.

Why this bag: Seed lots and grain destined for controlled-atmosphere storage need moisture exclusion from the moment the bag is sealed. A U-panel body with a tied PE liner provides this from fill through to delivery. Woven inner liner is specified where seed lot separation from the outer weave matters for traceability or contamination-prevention protocols.

Bulk Chemicals

What's packed: Hygroscopic inorganic compounds, polymer powder, chemical granules.

Why this bag: Many industrial chemicals absorb moisture and clump or degrade in transit. A PE or moisture-barrier liner arrests this without requiring coated outer fabric. Liner chemical compatibility with the specific compound is the critical pre-order check — confirmed between the buyer, India Pack, and the factory before production begins. For electrostatic-dissipative requirements, the Type C configuration should be evaluated separately: see Type C Bag with Label.

Pharmaceuticals and Excipients

What's packed: Pharmaceutical excipients, active ingredient intermediates, fine chemical powders.

Why this bag: Pharmaceutical supply chains often specify both a moisture-barrier liner and a cleanroom-compatible filling environment. The U-panel body provides a structurally cleaner internal seam profile. Factories with the relevant pharmaceutical-grade or GMP-equivalent certification should be confirmed before ordering [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
