Converters across India source their laminated nonwoven from GT Pack. Extrusion-coated, solvent-free, built for B2B converting lines.
Laminated nonwoven fabric is a B2B substrate — sold by the roll to converters, brand packagers, and finished-product manufacturers who turn it into the end product their customers use. GT Pack manufactures seven laminate structures across PET, BOPP, paper, kraft, and LDPE — all produced through extrusion coating with LDPE as the tie layer. No solvent adhesives. No curing chambers. Spunbond PP and SMS nonwoven bases, 25 to 200 GSM range. This page walks through the structures, the process, and the applications we know our substrate ends up in.
What happens when the laminate doesn't match the converter's process
B2B substrate buying is unforgiving. A converter who receives the wrong GSM, an inconsistent bond, or a delamination-prone roll loses production hours, scraps finished goods, and risks the relationship with their own customer. Three problems repeat across every category — and all three trace back to specification and process control at the manufacturer.
Delamination on the Converting Line
A weak bond between substrate and nonwoven shows up the moment the laminate is fed into a converting machine — peeling, edge separation, or full delamination at the seal. The roll is scrap. Production stops. The converter's customer waits.
GSM & Tie-Layer Inconsistency
Basis-weight variations or uneven LDPE coating thickness across the roll cause feed problems on high-speed converting lines and produce finished goods out of tolerance. Light spots tear; heavy spots jam. Both fail QC at the end-customer.
Solvent Residue in Adhesive Lamination
Adhesive-laminated substrates can carry solvent residue that compromises food-contact safety, contaminates fragrance products, and creates regulatory issues for medical and hygiene applications. Extrusion coating sidesteps the problem entirely — no solvent, no residue.
What is laminated nonwoven fabric, and how does extrusion coating bond the layers?
Laminated nonwoven fabric is a three-layer composite — an upper substrate bonded to a nonwoven base through a tie layer of polymer. The nonwoven base is typically spunbond polypropylene (PP fibres extruded and bonded into a continuous web) or SMS multi-layer nonwoven (Spunbond / Meltblown / Spunbond — a sandwich structure with finer filtration in the middle layer).
At GT Pack, the bonding is done through extrusion coating: molten LDPE is extruded from a slot die directly between the upper substrate (PET, BOPP, paper, or kraft) and the nonwoven base. The LDPE simultaneously bonds the two layers and becomes part of the finished structure — it is not just an adhesive that disappears after curing.
This is a different process from solvent-based dry lamination. Extrusion coating is solvent-free (no VOC residue), single-step (no 48–72 hour curing chamber), and faster on the production line. For substrates destined for food-contact, fragrance, or medical applications, the absence of solvent residue is a real advantage — not just a marketing claim.
Three-layer composite. The LDPE tie layer is extruded molten between the upper substrate and the nonwoven base, bonding them in a single solvent-free pass. LDPE thickness is calibrated to the customer specification.
The complete range of laminated nonwoven fabric GT Pack manufactures
Each structure pairs a different upper substrate with the spunbond or SMS nonwoven base, bonded through an LDPE tie layer. LDPE thickness is calibrated separately to each structure and customer specification — typically 10 to 35 microns, with thicker tie layers used where higher bond strength or moisture barrier matters.
PET Laminated Nonwoven
PET film extrusion-bonded to spunbond nonwoven via LDPE tie layer. PET adds dimensional stability, heat resistance, and a smooth printable surface. Known applications include insulation tapes, insulation backing, and industrial substrates that must hold shape under stress.
Double Side PET Laminated Nonwoven
PET film extrusion-bonded to both faces of the nonwoven, with LDPE tie layers on each side. Used where barrier and stability are required on both faces — for example in thermal insulation backing where both faces must resist moisture and hold dimensional shape. The symmetric structure prevents curl under temperature variation.
BOPP Laminated Nonwoven
BOPP film extrusion-bonded to nonwoven via LDPE tie layer. BOPP delivers excellent print clarity, gloss or matte finish, and a softer hand feel than PET. Preferred for premium retail packaging substrates, shopping bag faces, and applications where the finished product needs visual appeal.
Printed PET / BOPP Laminated Nonwoven
PET or BOPP film rotogravure-printed in reverse before extrusion lamination, then bonded to the nonwoven through the LDPE tie layer. The print sits protected between the film and the LDPE — never exposed to abrasion or wear. Up to 8 colours, photo-grade graphics, ideal for branded B2B substrate where the converter uses the printed face as the finished surface.
Paper Laminated Nonwoven
Poster paper or coated paper extrusion-bonded to spunbond nonwoven through an LDPE tie layer. Combines paper's natural finish and print receptivity with nonwoven's tear resistance. Known application: fragrance product packaging where paper's premium feel is required, but a tear-resistant backing is needed.
Kraft Paper Laminated Nonwoven
Heavier kraft paper extrusion-bonded to lighter nonwoven backing via LDPE tie layer. Standard application: clothing tags and hang tags — typically 100 GSM kraft on 32 GSM spunbond. Kraft delivers the natural, premium tag aesthetic; nonwoven backing prevents tearing under string or punch-hole stress.
LDPE Coated Nonwoven
LDPE extrusion-coated directly onto the nonwoven surface — no upper substrate, just LDPE forming a heat-sealable coated face on one side. The most cost-efficient structure for converters who need basic moisture barrier, heat-seal compatibility, and a smooth working surface without the cost of an additional PET, BOPP, or paper laminate.
We supply the substrate. You build the finished product.
Laminated nonwoven is a B2B substrate, not an end-use consumer product. GT Pack manufactures the laminated roll to your specification — upper substrate, GSM, LDPE tie layer thickness, base nonwoven, print, width — and ships it to your factory. What you turn it into is your business; we focus on delivering substrate that runs cleanly on your converting line.
This means we don't oversell end-use expertise we don't have. If you know exactly what specification you need, send us the spec sheet and we'll produce it. If you're a converter exploring options, tell us your end application and converting process, and we'll recommend the laminate, GSM, and base fabric that fits. Either way, the conversation stays grounded in what GT Pack can actually deliver — solvent-free, extrusion-coated substrate, on time, to spec, batch after batch.
The five steps of extrusion-coated nonwoven lamination
GT Pack uses extrusion coating with LDPE as the sole lamination method on this product line. The process is solvent-free, single-step, and runs faster than adhesive dry lamination because there's no 24–72 hour curing chamber to wait through. Here's what happens between raw materials and a finished roll on your shipping bay.
Base Preparation
The nonwoven base — spunbond PP or SMS — is unwound onto the lamination line. The surface is corona-treated to increase surface energy and create the micro-roughness LDPE needs to bond reliably.
Upper Substrate Feed
The upper substrate — PET film, BOPP film, paper, or kraft — is unwound on a parallel line. If the substrate is pre-printed (PET or BOPP), the print has been rotogravure-applied in reverse before this stage so it sits protected after lamination.
LDPE Extrusion
Molten LDPE is extruded from a slot die directly into the gap between the upper substrate and the nonwoven base. Coating thickness is set by die gap, line speed, and resin temperature — calibrated to the customer specification, typically 10 to 35 microns.
Nip & Bond
The three layers — upper substrate, molten LDPE, nonwoven — are pressed together at the nip between a chill roll and a pressure roll. The LDPE solidifies instantly as it contacts the chilled surface, bonding the structure in a single pass. No curing chamber needed.
Slitting & QC
The finished laminate is wound onto cores, then slit to the customer's specified width. Every roll passes basis-weight verification (GSM), bond-strength sampling, surface uniformity inspection, and visual QC for delamination or print defects. Passed rolls are packed with batch traceability and dispatched.

The questions B2B buyers actually search for on laminated nonwoven fabric
These are real questions converters and substrate buyers ask Google when sourcing laminated nonwoven — sourced from Google's "People Also Ask" panel, autocomplete suggestions, and IndiaMART buyer inquiry patterns.
What is laminated nonwoven fabric?
Laminated nonwoven fabric is a composite material made by bonding a film, paper, or coating onto a nonwoven base — typically spunbond polypropylene or SMS multi-layer nonwoven. At GT Pack, the bonding is done through extrusion coating, where molten LDPE is extruded between the upper substrate (PET, BOPP, paper, or kraft) and the nonwoven base.
The LDPE serves as the tie layer that bonds the two surfaces and also becomes part of the finished structure. The nonwoven provides softness, breathability, and tensile strength; the upper substrate adds barrier, print, or aesthetic; the LDPE layer creates the bond.
How is laminated nonwoven fabric manufactured at GT Pack?
GT Pack manufactures laminated nonwoven fabric through a five-step extrusion coating process:
(1) Base preparation — the nonwoven (spunbond PP or SMS) is unwound and corona-treated for adhesion.
(2) Upper substrate feed — PET, BOPP, paper, or kraft is unwound on a parallel line, pre-printed if required.
(3) LDPE extrusion — molten LDPE is extruded from a slot die directly between the substrate and the nonwoven, with thickness calibrated to the customer specification.
(4) Nip & bond — the three layers are pressed together at a chilled nip; LDPE solidifies instantly, bonding the structure in a single pass.
(5) Slitting & QC — the master roll is slit to specified width and quality-checked for GSM, bond strength, and uniformity.
The process is solvent-free — no adhesive, no curing chamber, no VOC residue.
What is the difference between extrusion coating and dry lamination?
Extrusion coating uses molten LDPE polymer extruded directly between two layers as the bonding agent. The LDPE solidifies as it cools, creating an instant bond and becoming part of the laminate structure. Solvent-free, single-step, no curing required.
Dry lamination uses solvent or solventless adhesive applied to one surface, then nipped to the second layer, then cured for 24 to 72 hours in temperature-controlled chambers. Allows more complex multi-layer structures but requires solvent recovery and curing infrastructure.
For substrates destined for food-contact, fragrance, or medical applications, extrusion coating is preferred because there is no solvent residue. GT Pack uses extrusion coating with LDPE exclusively for its laminated nonwoven product line — by design.
What is PET laminated nonwoven fabric used for?
PET laminated nonwoven fabric is used as a B2B substrate where the converter needs dimensional stability, heat resistance, and a smooth printable surface. Known applications include insulation tapes and insulation backing, premium packaging substrates, and industrial substrates that must hold shape under stress.
At GT Pack, PET is bonded to the nonwoven through an LDPE tie layer in a single extrusion-coating pass. Double-side PET laminated nonwoven places PET on both faces with LDPE tie layers on each side — used where barrier and stability are required on both sides, and the symmetric structure prevents curl.
What is kraft paper laminated nonwoven fabric used for?
Kraft paper laminated nonwoven fabric combines the natural finish and strength of kraft paper with the tear resistance of nonwoven. A common application is in clothing tags and hang tags — typically 100 GSM kraft / LDPE 25µ / 32 GSM spunbond, giving a durable, premium-feeling tag that resists tearing at the punch hole or string mount.
Other applications include eco-positioned packaging substrates, retail bag liners, and protective interleaves where a natural kraft aesthetic matters more than a printed film surface.
What is the GSM range for laminated nonwoven fabric?
GT Pack manufactures laminated nonwoven fabric across the 25 GSM to 200 GSM range (referring to the base nonwoven). LDPE tie layer thickness is calibrated separately — typically 10 to 35 microns — based on bond strength requirement and customer specification.
Light grades (25–50 GSM) — hygiene, fragrance packaging, lightweight protective covers, fine surface substrates.
Medium grades (50–100 GSM) — the majority of B2B packaging substrate applications, retail bag substrates, insulation tapes.
Heavy grades (100–200 GSM) — clothing tags, structural backing, premium shopping bag faces, industrial substrates.
Can laminated nonwoven fabric be printed?
Yes. Printing can be applied at multiple stages:
PET and BOPP laminates — the film is rotogravure-printed in reverse before extrusion lamination, so the print sits protected between the film and the LDPE tie layer. Up to 8 colours, photo-grade quality.
Paper and kraft laminates — the paper can be pre-printed using offset or flexo before lamination.
LDPE coated nonwoven — flexo printing is applied to the LDPE surface after coating.
Is extrusion coated nonwoven fabric food safe?
Extrusion coated nonwoven fabric produced with food-grade LDPE and food-grade upper substrates is suitable for indirect food contact applications. The extrusion coating process is solvent-free, which eliminates solvent residue concerns associated with adhesive-based lamination.
GT Pack holds ISO 22000 food safety certification and uses food-grade LDPE pellets and substrates when the end application requires it. Buyers should always specify the food-contact requirement upfront so the correct material grade is sourced for production.
What is the difference between spunbond and SMS nonwoven base fabric?
Spunbond PP is a single-layer nonwoven made by extruding continuous polypropylene filaments and bonding them into a web. Cost-efficient, breathable, durable — used as the base for most B2B laminated nonwoven applications including tags, packaging substrates, and basic insulation backing.
SMS (Spunbond / Meltblown / Spunbond) is a three-layer composite — outer spunbond layers for strength sandwiching an inner meltblown layer for filtration and barrier. Used where the substrate needs finer filtration properties, fluid resistance, or specific performance requirements. SMS is the base of choice for medical-grade applications.
GT Pack offers both as base fabric options across all laminate structures.
