G T Pack Industries manufactures poly coated paper to specification — PE coated kraft, LDPE coated white paper, single and double-side stock, cupstock board, FBB, freezer paper, medical grade, and release liner. The right base paper and the right coat decide whether your product reaches the shelf in saleable condition.
Poly coated paper is base paper or paperboard laminated on one or both sides with a thin layer of polyethylene — PE or LDPE — bonded directly to the paper through extrusion coating.
The polymer is melted, extruded as a thin film through a flat die, and pressed onto the moving paper web in a single pass, forming a continuous pinhole-free barrier layer. The result is a hybrid substrate that keeps the printability, stiffness, and recyclability profile of paper while gaining the moisture resistance, grease resistance, and heat-sealability of polyethylene.
For B2B packaging buyers, this matters in three places — moisture and grease control, heat-sealability on form-fill-seal lines, and the print-and-pack flexibility that comes with a paper-based substrate.
Uncoated kraft fails the moment cooking oil, frozen condensation, or steam from a hot pie touches it. A 12–18 micron PE coat changes the substrate's behaviour entirely — at a small fraction of the cost of a foil laminate.
Coated paper can be sealed without adhesives or hot-melts, which means it can be converted into cups, cones, sachets, and pouches on standard form-fill-seal lines.
Because the base is still paper, you can run rotogravure, flexo, or offset printing on it the same week you decide to launch — no plate retooling for a new substrate.
Choosing poly coated paper sounds like a substrate decision. It is actually a financial decision. These four mistakes account for most second-order rejections in the Indian FMCG supply chain.
A 60 GSM kraft will fail tensile strength on a high-speed wrapping line that needs 80 GSM. Reels snap, machines stop, downtime stacks up.
8 GSM PE on the inside of a cupstock board looks like it saved cost — until the third sip of hot coffee leaks through pinholes and your QC team is fielding warranty calls.
Single-side coated paper used where double-side was specified means the outer print starts feathering the moment the package hits a humid warehouse.
PE coated kraft is a moisture and grease barrier. It is not an oxygen barrier. Pack masala or roasted nuts in it without an aluminium foil interlayer and the aroma is gone in three weeks.
The fix: specify the right structure — base GSM, coat type, coat weight, coat side, and barrier expectations — before the paper is bought, not after.
Our extrusion coating capability spans the full commercial spread of base substrates and coating configurations. Each grade below is engineered for a defined application family.
The workhorse grade. Base paper (kraft, maplitho, or bleached) with a PE coat of 10–25 GSM on one or both sides. Heat-sealable, moisture-resistant, grease-resistant.
Low-density polyethylene coating gives a softer, more flexible film. Lower melt temperature makes it easier to heat-seal on older lines.
Paper coated with PE on only one face. The coated side faces the product; the uncoated side stays receptive to glue, ink, and grip.
PE coating on both faces. Both sides become moisture-resistant and heat-sealable — used where pack is sealed against itself or both faces face moisture.
Natural kraft base (50–120 GSM) with PE coat. Kraft strength carries heavy or sharp products; PE coat keeps moisture, oil, and grease out.
Bleached kraft pulp base for a clean white surface that prints sharply. PE coat does the same job as on natural kraft; the white substrate lets brand colour land cleanly.
Wood-free uncoated paper base with PE coating. Smoother surface than kraft, better print fidelity — used where the package needs a retail-grade look.
Folding Box Board with PE coating, 200–350 GSM. Combines carton rigidity with PE moisture barrier. Microwave-safe configurations available.
Specialty board for hot & cold beverage cups. Base 170–300 GSM, PE coating typically inside — single-side for hot, double-side for cold to handle condensation.
General-purpose coated board for clamshells, trays, food boats, and takeaway containers. Heat resistance to typical foodservice temperatures.
Single-side PE coated paper with the coated side facing product. Coat blocks moisture migration; uncoated outer accepts butcher pen marking.
Medical-grade paper with controlled PE coating for sterile barrier packaging. ISO 11607-aligned structures supplied on specification.
Paper substrate with silicone-over-PE release layer, giving a clean controlled peel. Carrier web for converters who laminate adhesive products on top.
Poly coated paper has earned a place in almost every industry that ships, serves, or sells a product where moisture, oil, or grease would otherwise destroy the pack. The grade and structure change with the application — the principle stays the same: the right coat on the right base.
Largest application by volume. Poly coated kraft for grease-heavy wraps (samosa, kachori, fried snacks), PE coated white kraft for premium retail snacks, FBB coated board for frozen food cartons. The challenge is matching coat weight to oil and grease exposure: 12 GSM PE handles light grease; 18–22 GSM is the safer spec for deep-fried products.
Burger wraps, French fry packets, sandwich liners, food boats, and paper bags with PE liners. The coat faces the food. The uncoated outer face takes the QSR brand print and the customer's grip.
Freezer paper for raw meat and fish portions; double-side PE coated paper for ice cream sticks and inner wraps; PE coated FBB for frozen ready-meal cartons. Condensation in the freezer attacks the package from both sides, which is why double-side coating is often non-negotiable here.
Cupstock board for paper cups (hot and cold), PE coated FBB for paper bowls and microwaveable containers. Single-side PE on the inside for hot cups; double-side PE for cold cups. Heat-seal integrity at the cup bottom is the failure point most cup buyers miss in their first spec.
Poly coated maplitho or bleached paper for tea bag tag papers; poly coated paper as the outer ply in 3-layer paper-aluminium-PE structures for premium loose-leaf tea, ground coffee, and whole-bean coffee. The paper carries the brand print; the aluminium ply carries the aroma barrier.
PE coated paper as the outer face of paper-aluminium-PE laminates for primary pharma packaging of powders, granules, and ORS sachets. The paper face takes batch number and expiry overprinting cleanly; the aluminium ply gives the barrier; the inner PE seals on form-fill-seal lines.
Medical grade poly coated paper for sterilisation pouches. Pre-sterilised device on the inside, peel-open paper face for clinician access without contamination. ISO 11607-aligned structures supplied on specification.
Poly coated paper for soap wraps, detergent sachet outers, and wet wipe overwrap. Resists moisture from the product side while staying printable on the outside for retail branding.
Moisture-resistant poly coated kraft for seed pouches, agro-input sachets, and fertiliser inner liners. The PE coat protects against humidity during long-haul transport and warehouse storage.
Poly coated kraft 80–120 GSM for moisture-resistant inner liners in cement bags, fertiliser bags, chemical drums, and engineering component packaging. The kraft strength carries the load; the PE coat blocks ambient moisture during ocean freight and humid warehousing.
Anti-moisture poly coated paper for primary packaging of capacitors, transformer windings, and sensitive electrical components where humidity exposure causes oxidation or insulation breakdown.
PE coated bleached board for premium retail cartons, gift packaging, and consumer pack outer cartons that must survive humid ocean freight. Often combined with offset or rotogravure printing for high-resolution brand graphics.
Barrier performance decides whether a packed product holds its shelf life. The table below compares two common laminate structures involving poly coated paper. Values shown are typical industry ranges; specific structures can be tested in our QC lab to validate performance for your product.
| Structure | WVTR (g/m²/24hr) | OTR (cc/m²/24hr) | Grease | Typical Application |
|---|---|---|---|---|
| Kraft 70 GSM / PE 18 µ Single-side coating |
12 – 18 | Not a barrier | Excellent | Burger wraps, oily snack wraps, fast food wraps |
| Paper 60 GSM / PE 15 µ / Alu 9 µ / PE 30 µ Paper-foil-PE laminate |
0.5 – 1.0 | 1 – 3 | Excellent | Pharma sachets, dehydrated food, premium tea & coffee |
PE coated paper alone is not an oxygen barrier. Products that need aroma retention or oxidation control require an aluminium or metallised interlayer.
The WVTR difference between plain PE-coated paper and a paper-aluminium-PE laminate is roughly 15× — which directly determines shelf life in months for moisture-sensitive products.
Poly coated paper enters the pouch world in two ways: as the entire substrate for light-duty single-use sachets, or as one ply in a paper-aluminium-PE laminate for retail and pharma pouches. The format you choose depends on product weight, shelf life, fill machine, and brand look.

Sourcing poly coated paper from a converter that only coats — and outsources printing, lamination, and pouch conversion — adds three handover risks: substrate mismatch, registration drift, and split QC responsibility. G T Pack runs the full process under one roof at our Greater Noida facility.
PE and LDPE coating of paper webs from 40 GSM to 350 GSM base; single and double-side coating; coat weight controlled batch-by-batch.
Up to 8-colour printing on coated paper and laminate webs; food-grade and pharma-compliant ink systems; cylinder-based print for consistent registration.
Dry, wet, and extrusion lamination for paper-aluminium-PE, paper-PET, and paper-metallised structures.
Precision slitters with automated web inspection for pinhole detection, edge alignment, and reel-to-reel consistency.
In-house pouch conversion to all eight formats covered above; sample pouches available for line trials before bulk commitment.
GSM testing, COBB water absorption, seal strength, peel strength, dimensional verification, batch-level traceability per ISO 9001 and ISO 22000.
When the paper, the coating, the print, the laminate, and the pouch all run through the same QC system, you eliminate the finger-pointing that delays FMCG launches. That single-supplier accountability is the operational reason most of our repeat buyers stay.
Whether you're sourcing burger wraps for a QSR chain, cupstock for a beverage launch, freezer paper for a meat processor, or paper-laminate pouch material for a retail brand — get the structure right at the spec stage, not after the first reject batch.
