PP spunbond non-woven rolls are the raw material for medical, packaging, agriculture, geotextile and many other industries. Market prices range widely, and the gap usually reflects quality differences. Understanding GSM, uniformity and tensile strength is the prerequisite for every successful purchase.
GSM: Application Determines Weight
GSM is the most fundamental specification. 15-30gsm suits disposable bedding and underpads; 40-80gsm suits eco-bags, bag lining and medical drapes; 100gsm+ is for geotextiles and heavy industrial protection. Huayue supports the full 15-200gsm range with widths up to 3.2m.
Uniformity & Tensile Strength: The Invisible Quality Divide
Uniformity affects dyeing consistency and print quality — rolls with large cross-direction GSM deviation produce visibly uneven bags. Tensile strength (N/5cm) determines durability in processing and use. Huayue's 11 automated lines feature online GSM monitoring, and every batch is lab-sampled, keeping the pass rate above 99.8%.
Width, Color & Customization
Whether the width fits your cutting plan directly affects material waste. Huayue offers 1.6m / 2.2m / 2.4m / 2.6m / 2.8m / 3.2m widths, custom colors by Pantone card, and sample development — confirm quality first, then scale production, minimizing purchase risk.
Eco Certification: A Plus for Global Markets
If your products target European and American markets, consider GRS-certified recycled non-woven (RPP/RPET). Huayue offers 30%-100% recycled content options with full GRS and TC certificates to help you clear customs smoothly.
Q1: How do I choose the right GSM?
Match GSM to the application: 15-30gsm for disposable bedding and underpads; 40-80gsm for eco-bags, bag lining and medical drapes; 100gsm and above for geotextiles and heavy industrial protection. If unsure, tell the factory the end use and confirm on a physical sample.
Q2: How can I judge roll quality?
Check three metrics: uniformity (cross-direction GSM deviation, which affects printing and evenness), tensile strength (N/5cm, which drives durability) and GSM tolerance (±3g or better is good). Ask suppliers for per-batch lab test reports — far more reliable than comparing price alone.
Q3: Which widths are available? Can they be customized?
Standard widths are 1.6m / 2.2m / 2.4m / 2.6m / 2.8m / 3.2m, and rolls can be slit narrower to match your cutting plan and reduce waste. Give us your machine in-feed width and slit count, and roll diameter and length can be customized.
Q4: What certifications are needed for EU/US export?
EU and US brands commonly require proof of recycled content, so choose GRS-certified RPP/RPET nonwoven. We offer 30%-100% recycled options with full GRS certificates and TC transaction certificates to clear compliance reviews smoothly.
PP or PET: Settle the Polymer Before You Compare Prices
Most price comparisons go wrong before they start, because PP and PET rolls are not substitutes. PP spunbond is lighter, with a density of 0.91 g/cm3 so the same grammage and width yields more area per ton, softer in the hand and cheaper per kilogram; it melts at about 160 C, which suits ultrasonic welding and heat sealing but rules out high-temperature use. PET spunbond costs more, carries higher tensile strength, holds its shape closer to 230 C and is naturally more UV-stable, while PP needs a UV stabiliser package for long outdoor exposure. Comparing only the price per ton is how buyers end up with a roll that fails on the conversion line. If you are still weighing the two, the PP versus PET comparison sets the decision out by application.
What Actually Moves the Price Per Ton
Spunbond is quoted per ton rather than per roll, because what you buy is polymer weight. Four variables decide the figure: grammage and width, since heavier and wider runs consume more polymer per metre and slow the line; colour route, since stock shades cost less than dope-dyed Pantone work that needs a colour change and a 1-ton minimum; virgin versus recycled, since GRS-certified rPP and rPET carry a premium that partly covers the per-shipment transaction certificate; and order size. Two enquiries with the same GSM can come back 20 percent apart purely on colour route and quantity.
Width and waste
A mother roll of up to 3.2 m slit to your finished width removes the off-cut you would otherwise pay for and then scrap. Give the feeding width and the number of strips, not only the finished bag size.
Consistency and downtime
Online GSM monitoring holds grammage inside tolerance along the roll. Wide swings show up as print misregistration and stoppages, which cost far more than the saving on a cheaper roll.
Tensile and claims
Tensile is measured in N/5 cm. A roll that meets GSM but misses tensile fails first at the handle or the seam, and the cost lands on you as returns rather than on the mill as a discount.
What to Check on the Test Report
Ask for the batch test report rather than a marketing sheet. Three lines matter: average GSM and its coefficient of variation, where a CV above roughly 5 percent shows up on the print line; tensile in both machine and cross direction, which are never equal and where the cross-direction figure fails first; and elongation. Thickness and hand feel you can judge from a free A4 swatch before committing, since hand feel is the one specification no number captures.
Six Things to Send With an Enquiry
Quotes come back faster and are easier to compare when the first email carries: GSM and tolerance, finished width plus the number of strips, colour as a Pantone code or natural and white, end use because it drives tensile and finishes such as hydrophilic or UV-stabilised treatment, quantity and the required delivery window, and destination plus any certificate the buyer will demand. Leaving out the end use is the most common reason a roll arrives technically on spec and practically wrong. Standard stock shades in standard specifications ship 7 to 10 days after deposit; custom Pantone or GRS material runs 10 to 15 days.
