🔍 At-a-Glance
The Chronovex Polar Grade PVC Roll is a cold-storage-grade transparent PVC strip roll engineered to stay flexible down to −25 °C without cracking, hazing or losing transparency. Standard PVC turns brittle below 0 °C — our polar formulation uses a cold-resistant plasticiser blend that keeps the strip soft, optically clear and food-safe across the full −25 °C to +60 °C range. Each 50 m roll is supplied with FDA-grade compliance certificate, IS 14625 test report and GST invoice.

✨ Key Features
- True polar flexibility: Stays soft and supple at −25 °C — strips swing open and self-close even in blast-freezer environments where ordinary PVC cracks within weeks.
- Crystal-clear transparency: >88% light transmittance lets forklift drivers and workers see through the curtain — reduces accidents and improves cycle time.
- Food-grade compliant: FDA 21 CFR 177.1950 + IS 14625 certified — safe for direct contact with raw and processed food in dairy, meat, seafood and frozen-veg plants.
- UV-stabilised: No yellowing under fluorescent or LED cold-storage lighting — maintains optical clarity for 3+ years.
- Self-extinguishing: Meets fire-retardant class B1 (DIN 4102) — will not propagate flame after ignition source is removed.
- Energy savings: Properly installed polar curtains cut cold-room energy loss by 30-45% versus open doors and 12-18% versus standard PVC at sub-zero temperatures.

🔧 Installation Guide
- Measure door width and height. Add 50 mm clearance on top and 25 mm at each side.
- Calculate strips using 2/3 overlap rule — e.g. 300 mm wide strip needs 200 mm centre-to-centre spacing. For freezer doors use full 100% overlap.
- Cut roll to door-height + 50 mm using a sharp knife or hot wire. Round the bottom corners with scissors to prevent snagging.
- Punch holes at 100 mm pitch along the top edge using brass eyelets (φ8 mm).
- Mount header rail (galvanised steel or stainless) above the door using M8 anchor bolts at 300 mm pitch.
- Hang strips from header rail hooks. Maintain consistent overlap. Allow 24-hour relaxation before final adjustment.
Typical install time: 60-90 minutes per door by a 2-person team.
❓ Top Questions
Down to what temperature does this PVC stay flexible?
Continuous duty −25 °C; intermittent exposure (door cycles) tolerated to −30 °C. Below −25 °C continuous, request our Super Polar (−40 °C) variant.
Is this food-grade safe?
Yes — our polar PVC is FDA 21 CFR 177.1950 compliant and IS 14625 certified for direct food contact. Every roll ships with food-safety certificate.
How long does the roll last in cold storage?
Typical service life is 3-5 years in 0 °C to +5 °C cold rooms and 2-3 years at −25 °C blast-freezer duty, with daily traffic of 50-200 cycles.
Difference between Normal, Polar and Super Polar?
Normal: 0 °C to +60 °C. Polar (this product): −25 °C to +60 °C. Super Polar: −40 °C to +60 °C. Standard PVC turns brittle below 0 °C — always specify polar grade for cold-chain applications.
⚖️ Polar vs Normal Grade PVC
| Aspect | Polar Grade (this roll) | Normal Grade |
|---|---|---|
| Lowest temperature | −25 °C continuous | 0 °C minimum |
| Cracking risk | None down to −25 °C | High below 0 °C |
| Best use | Cold storage, freezers, dairy | Workshops, warehouses, factories |
| Cost premium | ~25-35% over normal | Baseline |

📖 Glossary
- Polar grade: PVC formulated with cold-resistant plasticiser to stay flexible below 0 °C.
- Plasticiser: Additive that gives PVC its flexibility — polar grades use DOA or DEHA esters with low cold-flex points.
- FDA 21 CFR 177.1950: US food-contact safety regulation for flexible PVC films.
- IS 14625: Indian standard for PVC sheets used in cold storage and food contact.
- HSN 3920 49 00: Indian tariff classification for non-cellular PVC sheets (18% GST).
📚 Detailed FAQs
How is polar grade different from normal PVC chemically?
Polar grade uses cold-flexible plasticisers (typically DOA, DEHA or DINP blends) and a tighter resin K-value spec (K65-K70). Normal grade typically uses DOP/DEHP which crystallise and stiffen below 0 °C, causing brittle failure within weeks.
Will it yellow over time under LED freezer lights?
No — we use a UV-stabiliser package (HALS + benzotriazole) that maintains optical clarity for 3+ years under typical 4000-6500 K LED freezer lighting. Yellowing is a known failure mode of unstabilised PVC; ours doesn’t.
Can I print our company logo on the strips?
Yes — we offer pad-printing or hot-stamping in 1-2 colours for orders of 25+ rolls. Logo files (vector preferred) need to be supplied 3 weeks before dispatch.

📖 Product Overview & Buyer Guide
Everything an Indian cold-chain buyer needs to know about Polar Grade PVC strip rolls — in one place.
Polar Grade PVC Roll (Cold Storage PVC Strip Roll) by Chronovex Industries is a transparent, flexible PVC strip roll engineered specifically for cold storage, blast freezers and food-processing cold rooms. The polar plasticiser formulation keeps the strip soft and crystal-clear down to −25 °C — well below the brittleness point of standard PVC — while remaining FDA 21 CFR 177.1950 and IS 14625 compliant for direct food contact. Manufactured at our Noida plant and dispatched pan-India with GST invoice (HSN 3920 49 00).
🤔 Why polar grade and not normal PVC?
Below 0 °C standard flexible PVC begins to crystallise — the strip becomes stiff, loses its ability to swing closed, develops surface haze and eventually cracks under repeated door cycles. In a −20 °C cold room, a normal-grade curtain typically fails within 2-6 months and starts leaking cold air at every door opening. Polar grade uses cold-resistant plasticisers (DOA / DEHA blends) and a tighter K-value resin spec that keep the strip flexible right down to −25 °C continuously. The result: 3-5 year service life in cold rooms, 2-3 years even at blast-freezer temperatures, no cracking, no clouding, no productivity loss from a failed curtain. Cold-chain buyers who switched from normal to polar typically report 30-45% lower cold-room energy bills and zero unplanned curtain replacements.

❓ Frequently Asked Questions
🧊Down to what temperature does this PVC stay flexible?
Continuous duty down to −25 °C; intermittent (short freezer-door cycles) tolerated to −30 °C. For sustained operation below −25 °C ask for our Super Polar (−40 °C) variant. Standard normal-grade PVC turns brittle below 0 °C — never use it in cold-chain.
🍽️Is it really food-grade safe?
Yes. Every batch is tested against FDA 21 CFR 177.1950 (US food-contact regulation) and IS 14625 (Indian BIS standard for cold-storage PVC). Each roll ships with a per-batch certificate — acceptable for FSSAI, BIS and major QSR procurement audits.
⏱️How long does a polar roll last in cold storage?
Typical service life: 3-5 years in 0 °C to +5 °C dairy / pharma cold rooms, and 2-3 years at −25 °C blast-freezer duty with 50-200 door cycles per day. Plan a precautionary replacement before signs of cloudiness or stiffness appear.
⚡How much energy do polar curtains actually save?
Properly sized and installed polar PVC curtains cut cold-room energy loss by 30-45% versus uncovered doorways and 12-18% versus normal-grade PVC at sub-zero temperatures (because normal-grade stiffens and fails to seal properly). For a typical 100 m² cold room operating at −20 °C, that’s often ₹4-7 lakh saved per year.
📜HSN code, GST and invoicing for cold-chain projects?
Polar PVC rolls ship under HSN 3920 49 00 (non-cellular PVC sheets) at 18% GST. We provide GST-compliant tax invoices with HSN, batch number and FDA / IS certificate references — directly importable into SAP, Tally and Oracle ERP for cold-chain project accounting.
🛠️Do you do custom width, embossing or branding?
Yes. Custom thickness (1.5-4 mm), custom width (up to 600 mm) and printed company branding (1-2 colour pad-printing or hot-stamping) available for orders of 25+ rolls with 5-7 day lead time. For very large projects (100+ rolls) we also do embossed ribbed surface for additional grip and impact resistance.
