Poly Coated Glassine Paper

For greasy, fat-rich and aroma-sensitive products — sweets, bakery items, ghee-laden snacks, pharmaceutical wraps — ordinary paper is a liability. It soaks up oil within hours, leaves stains on the outer pack, and gives you no way to seal it. Even standard greaseproof stock stops at grease; it still lets moisture and water vapour through.

GT Pack's Poly Coated Glassine Paper is built for exactly this gap. It starts with a glassine base — a dense, supercalendered paper that is naturally grease-resistant and air-resistant, with a smooth, glossy, low-porosity surface — and adds a food-grade polyethylene (PE) coating that contributes the moisture barrier and heat-sealability glassine alone does not have. The result is a single substrate that is grease-proof, moisture-resistant, heat-sealable and an excellent print surface. Supplied in roll form, 80–120 GSM, widths up to 1500 mm, manufactured under four ISO-certified systems: ISO 9001, 22000, 14001 and 45001.

What Is Poly Coated Glassine Paper?

Poly coated glassine paper — also called PE coated glassine paper — is glassine paper that has been extrusion-coated with a thin film of polyethylene. Glassine itself is a smooth, glossy, semi-translucent paper produced by supercalendering: wood-pulp fibres are aligned and the sheet is pressed under high pressure until its pores close, creating a dense, low-porosity surface that resists grease and air without any coating. The PE layer then adds what glassine cannot do on its own — a barrier against moisture and water vapour, and a heat-sealable surface for converting into sachets and wraps.

At GT Pack, the structure is specified base-first — for example Glassine 70 GSM + PE 15 GSM coat — with PE coat weight tuned to the moisture barrier your product actually needs.

Why Glassine? The Natural Grease Barrier

Glassine's defining property is grease resistance — and it earns it mechanically, not chemically. Because supercalendering closes the gaps between the fibres, oil and fat travel through the sheet very slowly, keeping the outer surface clean. That makes glassine the preferred base for greasy and fat-rich products:

The surface is smooth and low-porosity — clean release, with no fibre shedding onto the product.

It is air-resistant, which helps protect aroma and freshness.

It is naturally pH-neutral — an advantage for sensitive food and pharmaceutical contact.

Its glossy, refined finish gives packs a premium look on the shelf.

What Does the PE Coating Add?

Uncoated glassine resists grease and light moisture, but it is not waterproof and cannot be heat-sealed. The polyethylene coating closes both gaps:

Moisture and water-vapour barrier — protects hygroscopic and moisture-sensitive contents.

Heat-sealability — the PE layer melts under heat to form a reliable seal, so the paper can be converted directly into sachets and pouches.

Added wet strength — the sheet holds up better in humid and oily conditions.

Together, glassine plus PE gives you grease resistance, a moisture barrier and a heat seal in a single material.

Where Is Poly Coated Glassine Paper Used?

Bakery & confectionery — wraps and liners for sweets, mithai, chocolates, cookies, pastries and donuts.

Fat-rich & fried foods — packaging for ghee-based snacks, namkeen and other oily products.

Pharmaceuticals — moisture-protective inner-wraps and printed sachets where a clean, low-porosity surface is required.

Food sachets — heat-sealed sachets for spices, premixes and single-serve products.

Interleaving — separating sticky or oily items so they do not fuse together.

Printing & converting — a premium print and pouching substrate; rotogravure (up to 8 colours) and flexo printable.

How Does Poly Coated Glassine Paper Compare to Other Poly Coated Papers?

Choose poly coated glassine when the surface quality and grease performance matter most — premium food, confectionery and pharma packs. Choose poly coated kraft when tear strength is the priority, such as industrial wrapping and heavier packs. Choose poly coated poster or chromo paper for economical printed wrappers. Glassine sits at the premium end of the range: the smoothest surface, the best natural grease resistance and the most refined finish.
