We can produce both reinforced or unreinforced circular fabrics with a weight range of 50-240 gr/m2 and width range of 30-225 cm
Fabric weight depends mostly on the SWL and SF of the big bag.
Usually the customer does not have to decide which fabric strength the FIBC must have as this is decided by ATEA sales agents according to the SWL and SF and the respective certificates.
However, a customer can always order an upgrade on fabric weight to get a stronger big bag.
Higher fabric weight (gsm) will lead to less bulging of the full big bag and make it more resistant against physical damages. Standard cloth weights are 165, 180 and 200g/m2.
There are four approved options in the measurement of fabric mass per unit area:
Option A, Option B, Option C, and Option D. Option A may be used for acceptance testing of commercial shipments since it has been used extensively in the trade. The second option is Option B which is applicable to a full-width sample cut from a full piece, roll, bolt, or cut. Unless otherwise specified, these results will include selvages and will be on the basis of conditioned fabric. Option C on the other hand is applicable when a small swatch of fabric is sent to the laboratory to be used as the test specimen. The results are considered to be applicable to the sample only and not necessarily to the lot from which the sample was taken.
Measurements by this method do not include selvages and should be reported as such, unless a selvage allowance is specified. The last option is Option D which is intended for use with narrow fabrics as so designated by the trade. This abstract is a brief summary of the referenced ASTM standard. It is informational only and not an official part of the standard.
These test methods cover the measurement of fabric mass per unit area (weight) and is applicable to most fabrics.
There are four approved options:
1.Option A—Full Piece, Roll, Bolt or Cut
2. Option B—Full Width Sample
3. Option C—Small Swatch of Fabric
4. Option D—Narrow Fabrics
