You've seen it on construction sites, greenhouses, factory floors, and warehouse shelves. A wide flat roll of plastic sheeting — protecting, covering, sealing, and lining everything it touches. That is a polythene sheet roll: one of the most useful, adaptable, and widely used plastic products in Indian industry today. Made from LDPE (Low Density Polyethylene), it bends without cracking, seals against moisture, and costs far less than rigid alternatives. At Bharat Plastic Manufacturing Co. in Pimpri MIDC, Pune, we've manufactured LDPE polythene sheet rolls since 1970 — this guide tells you everything you need to know before you buy.
What Is a Polythene Sheet Roll?
A polythene sheet roll — also called a plastic sheet roll, polythene covering sheet, or simply a roll of plastic — is a wide, flat film of low density polyethylene wound tightly around a core. Unlike polythene tubing (which forms a tube), a sheet roll is a true flat film: open on both edges, ready to unroll and lay flat across any surface. It is supplied in rolls of varying width, length, and thickness and can be cut to any size on site.
The word polythene is the common name for polyethylene in India and the UK. Specifically, LDPE (Low Density Polyethylene) is the grade used for most flexible sheet rolls — valued for its softness, clarity, high elongation before tearing, and outstanding moisture barrier properties.

Why LDPE? The Material Behind the Roll
Low Density Polyethylene (LDPE) — also written as polyethylene polythene in common industrial use — is a thermoplastic polymer produced by radical polymerisation of ethylene gas. Its branched molecular structure gives it a lower crystallinity than HDPE, which translates directly into the properties that make it ideal for sheet rolls: exceptional softness, high elongation (it stretches before it tears), and the ability to be sealed with heat.
Crucially, LDPE plastic is transparent to milky-clear, making it easy to see what is underneath it. It does not absorb moisture and provides an excellent barrier against water vapour — exactly what you need for damp-proofing, concrete curing, or protecting goods from humidity.

Where Is a Polythene Sheet Roll Used?
The polythene sheet roll has a staggering range of applications — from protecting freshly poured concrete on a construction site to covering a machine in a factory floor. Below are the most common industrial and commercial uses across India.
Construction — Floor & Surface Protection
Laid under concrete during curing to retain moisture, used as plastic sheet for floor protection during building work, and as a dust/debris barrier between work zones. 150–250 µm recommended for site use.
Damp-Proof Membranes (DPM)
Placed under floor screeds and concrete slabs to prevent rising damp. A key application of construction plastic sheeting in civil and residential projects. Typically 250–300 µm heavy gauge.
Agriculture — Mulch & Greenhouse Cover
Black polythene sheet is used for mulching to suppress weeds, retain soil moisture, and warm the root zone. Clear sheets are used as greenhouse roof films and crop protection covers.
Industrial — Machine & Equipment Covers
Rolls of plastic covering sheet are used to drape over machinery, pallets, and equipment during storage, transport, or maintenance — protecting against dust, humidity, and contamination.
Packaging Liners & Pallet Covers
Wide polythene roll film lines shipping containers, pallet bases, and packaging boxes to provide a moisture barrier. Widely used in FMCG, pharma, and export packaging operations.
Painters & Decorators — Masking
A key use of plastic on roll in finishing trades: masking floors, furniture, fixtures, and surfaces before painting or polishing. Lightweight, cuts easily with a knife, does not leave residue.
Cold Storage & Refrigeration Lining
LDPE remains flexible at low temperatures (unlike many other plastics), making polythene sheet rolls ideal as vapour barriers and liners in cold rooms, freezer units, and chilled warehouses.
Pond & Canal Lining
Heavy-gauge polythene sheets (200–300 µm) are used to line small ponds, water reservoirs, and irrigation canals — providing a cost-effective, flexible waterproof lining that conforms to irregular ground.
Section 04
Thickness Guide — Which Micron Should You Choose?
Thickness is the single most important specification when buying a polythene sheet roll. In India, thickness is measured in microns (µm), where 1 micron = 0.001 mm. The minimum legal thickness for plastic sheeting in Maharashtra is 50 microns under the Plastic Waste Management Rules — thinner products are non-compliant.
Here is a practical guide to polythene sheet thickness selection for common applications:
| Thickness | Best For | Typical Industries |
|---|---|---|
| 50 µm | Short-term indoor coverage, light wrapping | Painters Retail Packaging |
| 75 µm | General-purpose packaging liner, machinery wrapping | Warehousing Logistics |
| 100–125 µm | Standard floor protection, greenhouse cover | Construction Agriculture |
| 150 µm | Heavy floor use, outdoor machine covers | Manufacturing Construction |
| 200 µm | Damp-proof membrane, pond lining, cold room | Civil works Agriculture |
| 250–300 µm | Heavy-duty DPM, long-duration outdoor cover, water features | Civil engineering Industrial |

How Is Polythene Sheet Roll Manufactured?
Bharat Plastic manufactures LDPE polythene sheet rolls using the blown film extrusion process — the industry standard method for producing high-quality, consistent plastic film. Understanding the process helps you understand why factory-direct quality matters.
The key advantage of the blown film method is that it produces film with balanced molecular orientation — meaning the sheet is equally strong in all directions. This is why blown film polythene sheet rolls are tougher and puncture-resistant compared to cast film alternatives. Bharat Plastic's Pimpri MIDC facility runs multiple blown film extrusion lines, allowing custom widths, thicknesses, and colour variants to be produced to order.
"At Bharat Plastic, we control every stage of manufacturing in-house — from raw LDPE plastic compounding to the final wound roll. That's why our polythene sheet rolls deliver consistent gauge, clarity, and mechanical strength batch after batch."

How to Choose & Buy — Practical Buyer's Checklist
Buying the right polythene sheet roll means specifying five things correctly. Get these right and you'll receive a product that works the first time — without wastage or re-ordering.
Sheet Roll vs. Polythene Tubing — Which Do You Need?
Buyers often confuse polythene sheet rolls with polythene tubing rolls. The difference is simple:
A polythene sheet roll is flat film, open on both sides — best for laying flat as a covering sheet, floor protection, or lining. A polythene tubing roll is a continuous tube (seamless, no side seams) that you cut and heat-seal to make custom-length bags. If you're covering a floor, a machine, or using it as a damp-proof membrane — choose the sheet roll. If you're making bags for components or storage — choose the tubing roll.
