1,500 kg Dual-Spout FIBCs for Calcium Carbonate
For a 1,500 kg calcium carbonate fill, a dual-spout bag is worth quoting when your outlet and hopper can both accept it. Measure outlet diameter, clamp reach and clearance from lift point to hopper. Use the catalog’s 1,000–1,500 kg listing as a starting candidate and confirm the exact 1,500 kg configuration before a trial.
Before requesting a sample
- The starting specificationThe catalog range gives a starting point for selecting a dual-spout model. Confirm what applies to the 1,500 kg quoted build, including fabric, attachments, bottom closure and accompanying records.
- Inputs for your first reviewKeep the relevant drawing and the exact rating evidence together before scheduling a trial.
Dual-spout constructions in the shortlist
Qingdao Novapack Packaging Co., Ltd. manufactures woven polypropylene FIBCs in Qingdao, China. Tell us how you will fill and handle this bag so we can review the drawing, components and the checks you need on the selected build.
An industrial U-panel or tubular dual-spout bag gives us a construction to review. Add your powder density and target fill mass so we can distinguish interface fit from a verified load specification.
Confirm what applies to the 1,500 kg quoted build, including fabric, attachments, bottom closure and accompanying records.
Use the result to rule out unmatched models before requesting a production quote.
For a 1,500 kg target, send measured bulk density, height from lifting point to hopper rim and the length needed below the bag for the receiving connection.
Compare catalog candidates
| Catalog candidate | What the description shows | What to confirm for your order |
|---|---|---|
| Custom-Printed PP FIBC with Dual Spouts for Mineral and Plastic Pellet Shipments | Mineral and pellet listing with top and bottom spouts; a 1,000–1,500 kg range is shown | Confirm the 1,500 kg revision, top and bottom spout sizes, and filled bag height |
| Tubular PP FIBC Jumbo Bag with Dual Spouts for Powder and Granules | Tubular dual-spout entry lists 90 × 90 × 110 cm as a reference and 1,000 kg | Use as a geometry comparison. Request a different approved build for a higher fill mass |
| Custom-Size Virgin PP U-Panel Jumbo Bag with Top and Bottom Spouts | U-panel with upper and lower spouts | Put flange diameter, clamp reach and discharge sleeve space on the interface sketch |

Upper and Lower Spout Assembly
The two sleeves are cut to separate dimensions and sewn to the top and base at their approved positions. A liner, when specified, also needs its own neck alignment and closure detail. Agree how the upper sleeve lands on the outlet and how far the lower sleeve needs to reach, then verify those interfaces on the sample.
Technical background PP tape for woven packaging and FIBC fabric
Compare seam, coating and liner choices
Fitted PE and Aluminum-Film Liners for Existing FIBCsCutting and sewing establishes each sleeve's center, length and reach at the clamp. If the liner continues through either sleeve, its neck and closure need separate dimensions.
Approve two marked interface drawings showing sleeve diameter and usable length above and below the bag.
Discharge space above the hopper
Measure the space from the approved lifting point to the hopper opening. Allow for the loaded bag and the handling space your equipment needs around the bottom connection.
- Account for lift-to-hopper clearanceThe frame has to accommodate the loaded body, available sleeve reach and access to the lower closure. Check the working envelope with your site team using its approved procedure.
- Acceptance recordProvide the station sketch and include the lowest fixed obstruction and operator access needs.
Filled bag height at the target load
A flat drawing gives you the nominal bag size. Use an approved fill trial to determine the height at your target mass and compare it with the measured equipment space.
| Technical check | Use the actual calcium carbonate grade and bulk density in its filling condition. A different degree of aeration or settling can change operating height for the same net mass. |
|---|---|
| For approval | Record target weight and measured filled height for at least the applicable trial condition. |
A dust-control option matched to the powder
Keep a note of where fine powder travels during filling and emptying. Request the fitting or seam construction that addresses that location and record what you see in the trial.
The top sleeve connection, seam line and discharge mouth can release powder at different stages. Compare seam treatment and fitted liner choices against where the escaping powder is found.
Record observations by filling, interim transfer and discharge on the same sample sheet.
Bottom sleeve and closure review
Agree how the receiving point will engage with the bottom sleeve. Keep the agreed sleeve dimensions and closure detail on the bag specification used for the sample.
- Review access to the lower closureCompare the reachable closure position on the sample with the hopper sketch. Outlet length alone omits the space the assembled sleeve and its tie occupy.
- Acceptance recordRecord which station condition and opening method the buyer's process team approves.
A trial at both interfaces
Have your team record coupling fit, approach clearance, dust observations and powder left in the bag after the trial. Keep the same material and settings when you compare bag versions.
| Technical check | Check empty fit at each station. Then under the agreed trial plan compare discharge behavior and residue by candidate at the same net fill. |
|---|---|
| For approval | Keep the sample ID, powder grade, photographs and any follow-up change appointment together. |
Calcium carbonate details for the quotation
Share the grade and bulk density along with the target 1,500 kg fill, lift point and both outlet dimensions. A simple photo of the workspace can clarify which space is usable.
- What the South Korean calcium carbonate enquiry specifiedA 1,500 kg request called for a woven PP body, filling and discharge spouts, and forklift handling. The buyer also asked about reuse. That moved the brief beyond sleeve fit and into a separate review of the exact bag build, reuse conditions and supporting evidence.
- Acceptance recordFor a comparable order, send your powder data and sleeve interfaces. Record any repeat-use request in its own approval item.
A dual-spout sample brief
Include the filling sketch, discharge sketch and sign-off conditions in one enquiry. We can review which catalog construction is closest and which dimensions require a sample.
List spout measurements and net load, plus the quantity, destination and requirement for lot identification or test records. Mark which dimensions can change.
Ask for a rated configuration and sleeve drawing to review before ordering the sample.
Contact and Quote Details
Send your specification or a reference sample and include the order quantity and destination. Use the inquiry form to start your request. Send drawings or sample photos by email.
- Contact the Qingdao teamTell us what you pack or protect, and identify the operating condition that makes or breaks your purchase. Put the reference sample or drawing number in the message subject so it stays with the order.
- What the factory can reviewAttach the necessary evidence and ask for a sample, drawing review or quotation as the first deliverable.
