FIBC Bulk Bags (Ton Bags): Heavy-Duty Bulk Packaging for Global Industries

2026-11-03 10:35:00

When your product needs to move in bulk — powders, granules, pellets or aggregates — nothing beats the efficiency of FIBC bulk bags. At Zhejiang Saiqiang Plastic Co., Ltd., we manufacture FIBC bulk bags, jumbo bags and ton bags built for heavy-duty storage and transport, with capacities from 500 kg to 2,000 kg to match your filling and shipping requirements.

Engineered for Heavy Loads

As an FIBC bulk bag manufacturer, we produce both one-way FIBC and circular woven FIBC designs, using high-tenacity polypropylene fabric for maximum strength. Options include custom lifting loops, filling spouts, discharge spouts and duffle tops, so every bulk bag can be tailored to your handling equipment and product characteristics.

Protection for Your Product

For moisture-sensitive materials, we offer bulk bags with liner options and lamination to keep contents dry and contaminant-free. Anti-static and UV-stabilized configurations are available for demanding applications, making our jumbo bags suitable for chemicals, minerals, food ingredients and construction materials.

Specifications at a Glance

How to Specify an FIBC for Your Product

Start from bulk density, not from the capacity printed on the bag. A tonne of urea occupies roughly 1.3 cubic metres, while the same tonne of cement powder takes well under one. A 1000kg bulk bag sized for urea will sit half empty and top-heavy with cement; the reverse case overworks the fabric. Send us the density and the fill weight and the dimensions follow from those two numbers.

Then match the openings to the filling line. Gravity filling from a silo wants a wide, straight spout, while screw and pneumatic fillers run cleaner with a narrower spout and a vented top. Discharge decides the base: flat for tipping or slitting, cone or iris for controlled emptying into a hopper. State whether the bag is lifted once or goes back into a multi-trip loop, because a single-trip bag should not be reused indefinitely.

The costliest mistakes are simpler than buyers expect. Ordering by capacity alone produces a bag that no longer fits the pallet footprint. Leaving UV stabilisation off a bag that stands in the yard for months shortens its life. A liner also eats usable volume, so a bag that held a tonne unpacked may need one size up. And as a bulk bag for export, it must be specified against the container plan, not ordered afterwards.

Custom Printing for Easy Identification

Clear labeling is essential in bulk logistics. Our ton bags can be custom printed with your logo, product name, handling instructions and safety information, helping your team and your customers identify contents quickly and safely. Buyers who compare one jumbo bag supplier with another usually find the print quality tells them more about the factory than the price list does.

Global Bulk Packaging Partner

As an experienced FIBC bulk bag supplier, we support buyers worldwide with professional export documentation, strict quality control and on-time delivery. Every batch is checked for tensile strength and seam integrity and drop tested from 1.2 metres before it leaves the line.

Frequently asked questions

How much does an FIBC bulk bag cost?

There is no single FIBC bag price, because four things move it: working load, bag dimensions, whether a liner or coating is added, and print. A plain 1,000 kg bag sits at the low end; a coated bag with a PE liner and multi-colour print at the other. Send dimensions, fill weight and annual volume and we quote the exact construction.

Which bulk bag size do I need for 1,000 kg?

It depends on bulk density. Divide the fill weight by the density to get the volume the bag must hold, then check the filled height against your filler and your container. Dense powders need a smaller bag than fluffy granules at the same weight. Give us the density and we will confirm the size rather than guess.

Can bulk bags be stored outdoors?

Yes, when the fabric is UV stabilised, which we offer as a standard option on our ton bags. UV stabilisation slows the strength loss that sunlight causes, so a bag can stand in a yard through a season. For long storage of hygroscopic products, pair it with a PE liner so rain and humidity never reach the product.

What is the minimum order quantity?

Minimum order is 500 pieces per size, which keeps a first trial affordable before you commit to volume. Custom printing is available at the same minimum. To start, send bag dimensions, fill weight, product type and monthly volume, and we will confirm the construction and send a sample for filling trials.

Tell us the fill weight, the bulk density and how the bag will be lifted, and we will recommend the base, liner and fabric weight that fit. You can check the reinforced-base load ratings or send your bag dimensions for a quotation.
