Insulated Box Manufacturer & Supplier in India
Insulated boxes that hold 2–8 °C for up to 120 hours without a compressor, generator or reefer. Wedge Industries Limited supplies the complete thermal packaging range — WedgeVac vacuum insulated (VIP) cold boxes, rotomoulded ice boxes and fish boxes, EPP cold-chain boxes, aerogel-lined shippers, PCM coolants and XPS cold-store board. We make the VIP, aerogel, XPS and PCM that go inside the box, so the thermal design is done in-house.
Why a vacuum insulated box beats a PU box
An insulated box keeps a payload at a set temperature for a set time by slowing heat flow through its walls; the lower the wall’s thermal conductivity, the longer the hold and the less coolant it needs. Same 50 mm wall, same −10 °C payload, same 40 °C ambient, steady-state heat transfer calculated to ASTM C680:
| 50 mm wall build-up | Thermal conductivity | Heat gain into the box |
|---|---|---|
| Conventional PU / PUR foam | 0.023 W/m·K | 21.7 W/m² |
| Wedge HVI-PSV vacuum insulation panel | 0.0042 W/m·K | 4.15 W/m² |
Roughly 5× less heat gain through the same wall thickness. That is why a WedgeVac insulated box holds 2–8 °C for 70–120 hours on a fraction of the gel-pack payload a PU box needs — more paid payload per box, lower dry weight and lower freight cost per consignment. See the vacuum insulated panel range.

VIP cold boxes for medicine, vaccine and frozen food transport
These are Wedge builds, not renders. The vacuum insulation panels are fitted as a six-sided liner inside one of three outer shells. Choose the shell by how the box is handled: PP hollow board for courier and single-trip pharma lanes, EPP for reusable loops and frozen food, and a fibreglass-faced panel box for the longest 2–8 °C hold time.
Rotomoulded ice boxes and fish boxes
Rotomoulded HDPE insulated ice box
PU-filled rotomoulded HDPE coolers in 25, 50, 100, 200 and 500 litre sizes for marine, defence, field and outdoor use.
Insulated fish & seafood box
Rotomoulded HDPE, PU-filled fish boxes from 60 L, 100 L, 200 L, 300 L and 500 L to 660 L for landing centres, processing plants and fish, meat and poultry transport.

How to specify the right insulated box
Four inputs decide the box. Send us these and we will size the insulation and the coolant for you.
- Payload temperature: −70 °C (dry ice) · −21 °C (frozen) · 2–8 °C (chilled / pharma) · 15–25 °C (controlled room temperature) · hot holding.
- Duration: door-to-door hours including transit, handling and buffer. A 48-hour lane and a 120-hour lane are different boxes.
- Ambient profile: an Indian summer lane peaking above 40 °C is a far harder duty than a monsoon or winter lane — the input most buyers get wrong.
- Payload volume and reuse: single-trip EPS, or a reusable EPP / VIP box on a return loop — the reuse count usually decides the economics.
Insulated box applications
- Pharmaceutical & biotech: vaccine distribution, biologics, clinical trial supply, insulin and cold-chain APIs — aligned to WHO cold-chain practice.
- Seafood & marine: landing centres, processing plants, domestic fish and meat movement.
- Quick-commerce & food delivery: dark-store dispatch, rider backpacks, meal kits.
- Dairy & ice cream: chilling centres, distribution vans, frozen dessert retail.
- Diagnostics: specimen and blood transport under UN3373.
- EV & energy storage: thermally controlled Li-ion cell and pack movement — see EV battery insulation.
- Cold storage construction: XPS board and panels for cold rooms — see prefab cold storage and the mini cold storage price guide.
Why buy an insulated box from Wedge Industries Limited
- Insulation maker, not a box reseller: VIP, aerogel, XPS and PCM are our core products, so each insulated box is thermally designed in-house.

Insulated box FAQs
How long can an insulated box hold 2–8 °C?
The WedgeVac vacuum insulated box holds 2–8 °C for 70–90 hours in the standard VIP + PU build and 90–120 hours in the VIP + PET + EPP build, with the correct PCM coolant payload. An EPS or thermocol box of the same size holds a fraction of that; the exact figure depends on your ambient profile.
What is the difference between a VIP box and an EPS or thermocol box?
A vacuum insulation panel has a thermal conductivity below 0.004 W/m·K, conventional PU foam about 0.023 W/m·K and EPS higher still. Through the same 50 mm wall a VIP admits roughly five times less heat than PU — a thinner wall, more payload volume and far less gel pack or dry ice.
Which PCM temperature should I use?
Wedge supplies phase-change coolants at −21 °C, 0 °C, +5 °C and +22 °C. Frozen payloads use −21 °C; 2–8 °C pharma lanes typically use 0 °C or +5 °C; controlled-room-temperature (15–25 °C) lanes use +22 °C. Conditioning and packout instructions come with every system.
Can you supply a dry-ice shipper for −70 °C?
Yes. The WedgeVac VIP core is rated for −90 °C to +80 °C, so it suits dry-ice and deep-frozen shipping. Dry-ice shippers need venting and dangerous-goods documentation; we supply the box and the packing configuration.
Do you supply EPS-free, recyclable insulated packaging?
Yes. The paper and corrugated insulated liner range is EPS-free and curbside recyclable for D2C food, meal kits and brands under Extended Producer Responsibility. Reusable EPP and VIP boxes are the other route.
What is the price of a VIP insulated box?
Wedge VIP cold boxes start at ₹9,203 for the 13.8 L WedgeVCB-V13 (70–90 hours at 2–8 °C) and ₹9,358 for the 14 L V13E (90–120 hours), for orders of 10–99 boxes. The 140 L V140 is ₹27,790. Orders of 100+ boxes are about 20% lower and 1–9 boxes about 60% higher. Prices are ex-works, excluding GST and freight; PCM coolant sets are extra.
What are the minimum order quantities and lead times?
MOQ and lead time vary by product line, size and whether the insulated box is a standard model or a custom tool. Send your payload, duration and annual volume and we confirm both with the quotation.
Shipping temperature-sensitive goods?
Payload temperature, door-to-door hours and annual volume — that is all we need to size your insulated box and coolant.
