A focused guide to black LDPE sheet — why it's specified over natural sheet, the full 60-500 micron range, and what actually drives pricing.

Why Buyers Specifically Ask for Black LDPE Sheet
A large share of LDPE sheet enquiries in Bangalore ask for black specifically rather than any colour — and it's a deliberate choice, not a default. Black LDPE sheet blocks light transmission, which matters for outdoor construction covering, weed suppression under covered ground, and curing applications where consistent shading helps avoid uneven concrete drying. It also tends to handle prolonged sun exposure better than natural sheet over a multi-week site duration.
The Full Micron Range Explained: 60, 100, 150, 200, 250, 500
Micron thickness measures the sheet's gauge — the higher the number, the thicker and more durable the sheet, and generally the higher the material cost per roll. 60 and 100 micron are the lightest options in our range, suited to short-duration covering and packaging where the sheet won't face rough handling. 150 micron is a practical middle ground for general site use.
200 and 250 micron step up into more demanding applications — curing, damp-proofing, and covering that needs to withstand wind, foot traffic or extended exposure. 500 micron is the heaviest-duty option we stock, used where the sheet is under continuous ground contact, heavy material load, or needs maximum puncture resistance.
What Actually Affects LDPE Sheet Pricing
Three factors drive LDPE sheet pricing more than anything else: micron thickness (thicker sheet uses more raw material per roll), order quantity (bulk roll orders typically unlock better per-kg or per-roll rates), and roll size (custom widths and lengths can affect cost versus standard stock sizes). Because raw material costs for polyethylene fluctuate, we recommend confirming current pricing at the time of order rather than relying on a static published rate.
Roll Sizes and Custom Requirements
Standard roll sizes cover most construction and industrial covering needs, but for larger sites or specific applications, custom roll width and length can be arranged on bulk orders. If your project has an unusual coverage area — an irregular excavation shape, for instance — it's worth sharing the dimensions upfront so we can advise on the most efficient roll size rather than over-ordering standard rolls.
How to Place an Accurate Order the First Time
The fastest way to get an accurate LDPE sheet quote is to share four details in one message: the micron thickness (or the application, if you're not sure of the micron), colour (black or natural), total quantity or coverage area, and delivery location. This avoids the back-and-forth that slows down site-critical orders.
Quick Comparison
| Micron | Relative Cost | Best Suited For |
|---|---|---|
| 60 Micron | Lowest | Light packaging, short-term covering |
| 100 Micron | Low | General dust/light protection |
| 150 Micron | Medium | General construction site use |
| 200 Micron | Medium-High | Curing, medium-duty covering |
| 250 Micron | High | Heavy curing, lining |
| 500 Micron | Highest | Maximum durability, ground contact |
