Nonwoven Fabric Width and Roll Length Guide: What Buyers Get Wrong
Width is a specification buyers get wrong constantly. No page addresses it clearly with correct figures. Olefins Pakistan explains nonwoven fabric width and roll length guide with mother roll width, slit width, roll length, diameter and weight — see glossary of nonwoven terms for nonwoven fabric meaning — Karachi factory standard options as per TDS library.
Width & Roll Length Specs — What Olefins Offers — Ex-Stock Karachi
| Parameter | Standard / Range (as per TDS) | Common Buyer Mistake | Correct Way — Olefins Recommendation |
|---|---|---|---|
| Full Width | 60cm, 80cm, 100cm, 160cm, 210cm | Asks 150cm width — non-standard, waste high | Choose 160cm or 210cm mother roll — best yield, slit available as per TDS |
| Slit Width | 10cm to 105cm — any slit | Forgets tolerance ±0.5cm and edge quality | Mention slit + tolerance — e.g., 50cm slit ±0.5cm — precision slitting, clean edge |
| Roll Length | 200m to 2500m per roll — GSM dependent | Orders by kg only — length miscalculation | Order by meters: 15 GSM ~2000m/roll, 20 GSM ~1500-2000m/roll (50kg, 160cm), 40 GSM ~800m/roll — see GSM guide |
| Roll Diameter | 40cm to 90cm — machine dependent | Ignores dia for forklift / storage | Check 70cm dia fits your unwind — confirm before dispatch |
| Roll Weight | 25kg to 120kg | Overweight for manual handling | Request 25-50kg if manual, 80-120kg if forklift — as per TDS |
| GSM Range | 10 GSM to 150 GSM as per application — see TDS | Assumes same length for all GSM | Higher GSM = shorter length — check TDS for roll length per GSM |
Formula: Roll Length (m) = Roll Weight (kg) × 1000 / (Width (m) × GSM) — Olefins reports as per TDS with method and tolerance as per lab report. For ex-stock, contact Olefins team.
Buyer Mistake #1 — Width Confusion — How to Avoid
Buyers write "width 1m" — but 160cm machine se 100cm slit + 60cm waste hota hai. Correct: order full width 160cm or 210cm if you can use for big bags, or 50cm x 2 up — same mother roll se 2 slits — no waste. See our nonwoven for shopping bags and glossary for slitting plan for maximum yield.
Buyer Mistake #2 — Roll Length Confusion — GSM Relation
Roll length is not fixed. It changes with GSM option, width and roll diameter. Many buyers order by kg only and miscalculate meters. For example 15 GSM gives around 2000m per roll for 50kg and 160cm width, while 40 GSM gives around 800m for same weight. That is why Olefins quotes by meters as per TDS, with GSM option, width and roll weight mentioned, and provides COA per lot. For exact, check product portfolio and TDS library.
Buyer Mistake #3 — Slit Tolerance, Edge and Diameter
Slit tolerance ±0.5cm and edge quality affect bag making and hygiene line. Wavy edge causes machine stop. Roll diameter 40cm to 90cm affects unwind stand. Olefins uses precision slitting with clean edge, reports tolerance as per TDS, and offers multiple diameter options. For hygiene, see nonwoven for hygiene and spunbond fabric grades. Ask for edge sample before order.
How to Select Width for Your Application — Olefins Guide
Shopping Bags, D-Cut and W-Cut Bags
Select slit width as per bag size plus seal area. Olefins offers 10cm to 105cm any slit as per TDS for bag converters, with full width 160cm and 210cm mother roll for maximum yield. Refer shopping bags guide for calculation and slitting plan for zero waste.
Hygiene — Diaper Topsheet, Backsheet, Sanitary Napkin
Hygiene machines need exact width — topsheet and backsheet widths differ. Topsheet is hydrophilic treated for fast strike-through, backsheet is hydrophobic for barrier. Olefins offers hygiene grade with treatment as per TDS, available in multiple width options. See GSM guide and hygiene application page.
Medical Gowns, Drapes, SMS and SMMS
Select width as per gown pattern cutting to minimize waste. SMS is S+M+S, SMMS is S+M+M+S for higher barrier. Olefins offers SMS and SMMS in multiple width options as per TDS, with BFE and hydrostatic head as per international standard.
