FIBC (Big bag) Glossary Terms:

Bag Size: The dimension of an FIBC measured from the seam to seam for Length, Width or Height.

Body Fabric: Main fabric used on bag body of a u-panel, four panels or circular bag. Coated/ laminated or uncoated/ non-laminated.

Bottom Fabric: The bottom material of a tubular or four panel bag.

Bottom Spout: Also named Discharge Spout, used as an outlet to empty the contents of the BIG BAG.

Breathable Fabric/ Bags: Fabric/ bags with uncoated or non-laminated.

Circular Big Bag: Also called a tubular big bag, it is made from fabric weaving out from a circular loom, which is then cut into a proper length for specified bag height, thereby eliminating the vertical seams on each of the bag’s sides.

Cone Top: A variation of an inlet, where the top is a pyramid-type to allow over filling of the bag. Also called a conical top.

Denier: The weight of yarn per 9,000 meters in gram.

Discharge Spout: Also called bottom spout, used as an outlet to empty the contents of the FIBC bag.

Fabric Weight: The measure of the fabric weight in ounces per square yard or grams per square meter. A typical standard weight is 6.5 oz./sq.yd or 180 g/㎡.

FIBC: Short name of Flexible Intermediate Bulk Container.

Fill Spout: Also called inlet spout or top spout, used as the inlet for filling an FIBC bag. It is designed to fit the customer’s filling chute during loading.

Form-Fitted Liner: Designed to form the exact shape of the FIBC outer bag. Form-Fit Liners will allow improved filling and complete discharging of product.

Lift Belt: Also called a lifting loop or lifting straps, supporting the bag’s Safe Working Load, (SWL), of a filled bag during handing & transport. It may be made of either a stiff strap or soft strap. It comes in various widths and strengths according to specified each bag specification. Typically lift loops have a tensile strength between 3000 and 5000 pounds.

Loop Height: The free loop height measured from top edge of bag body to the middle of the free end of the link belt.

Multi-Trip FIBC'S: Bags designed in accordance with British Standards requiring a 6:1 Safety or Service Factor (SF). Note: Most manufacturers do not offer any guarantee or recommendations for multiple uses of bags. Since the inspection of the used bags is beyond the control of the manufacturer, they have no way of knowing if a bag is damaged in its initial use. For additional information regarding multi-trip bags, reference ISO 21898.

Safe Working Load: SWL stands for the total amount of load, (in pounds or kilograms), which a bulk big bag is designed to lift. Note: Most of customers use the metric system that 1 ton equals to2205 pounds or 1000 kilograms.

Safety Factor: Also known as a Service Factor, it is an industrial standard requiring the FIBC big bag to stand five or six times its Safe Working Load (SWL), normally written as a ratio at “5:1 or 6:1 SF”.

Sift-Resistant Construction: A feature of an FIBC bulk bag that provides resistance from product sifting when the bag is filled with very fine materials. And it also referred as “Sift proof” construction.

This typically use coated (laminated) fabric and filler cord in the sewing lines.

Single Trip Big Bag: An FIBC designed on terms of British Standards or ISO 21898-2005 requiring only a 5:1 safety factor for single trip usage.

Soft Strap: A lifting belt produced by polyester or polypropylene multifilament yarns.

Stiff Strap: A type of lifting belt weaved using multifilament yarns as weft and polypropylene yarns as warp, allowing it to stand more upright after big bag filled with goods.

UV Stabilized: A feature of an FIBC (big bag) fabric that provides protection from prolonged exposure to the sun’s degrading UV rays. An additive is added to the resin prior to yarns extrusion providing this protection.

Warp: It refers to Yarn or tape in a fabric, oriented perpendicular to the Weft yarn during weaving. It should go from top to bottom in the body fabric. It’s also identified as the yarn in the “machine direction”.

Weft: It refers to Yarn or tape in a fabric, oriented perpendicular to the Warp yarn during weaving. It should go from left to right in the body fabric. It is also identified as the yarns placed by the bobbins of the looms.

Yarn/Tape: Extruded PP sheet slit and stretched in annealing ovens to form part of the woven fabric for the FIBC bulk bag.

Big bag 1000kgs (Jumbo bag1000kgs or bulk bag 1000kgs) can be widely used in different fields. Such as Chemicals, construction materials, plastic raw materials, Mineral products, Firewood,and other types of powder, granules, block goods packaging.

1. PP raw material: We use 100% virgin PP material for drawing and extruding polypropylene fiber.

2. Draw bench silk: To Draw and extrude the weft and warp fiber for weaving the fabric.

3. Fabric and straps weaving: Fabric weigh from 60gsm to 250gsm and Straps weight from 35g to 100g.

4. Fabric cutting and Printing:We have 6 fabric cutting machine and 2 sets 4-color available printing machine.

5. Big bag sewing:Standard sewing, Chain stitch and lock stitch available and monthly 200,000 bags capacity.

6. FIBC bag dust-proof treatment:To ensure there’s no dust nor small threads inside the bag.

7. QA & QC: There are totally 10 people for QA and QC inspection.

8. Packaging: Normally packed on bales and Pallet or according to client’s require.

Jumbo big bag also known as bulk big bag, normally produced from Polypropylene woven fabric with lifting loops that allow the bag to be filled from top and discharged from the bottom. It widely used in the fields of Industrial materials, Chemicals, Minerals, Agriculture products and so on. We have served more than 500 customers covering hundreds of different packaging solution.
