Thermocol Box Sizes for Every Business: Food, Fish, Pharma & Dairy

"What size thermocol box do I need?" doesn't have a single answer, it depends entirely on what you're shipping, how far, and how sensitive it is to temperature. Here's a practical breakdown by industry, based on what Pakistani businesses in each category actually order.

Full pricing across all sizes: see our EPS Boxes guide.

Food Delivery & Catering

Typical size range: Small to medium (2-15L capacity)

Food delivery businesses generally need boxes sized for single-order or small-batch delivery, large enough to keep a meal at safe temperature during transit, small enough to be practical for a delivery rider to carry on a motorbike. Catering businesses handling larger event orders scale up to the medium-to-bulk range, particularly for maintaining food temperature across multi-hour events.

Practical consideration: disposable, single-use grade boxes are standard here, since food delivery packaging typically isn't returned or reused, cost-efficiency at this volume matters more than the reusability that matters for other industries below.

Seafood Industry (Karachi-Concentrated)

Typical size range: Medium to bulk/commercial (15-100L+)

Karachi's active seafood supply chain moves substantial volume daily from harbor to market, and fish boxes here need reinforced construction specifically, wet, cold, ice-packed conditions are harder on a box than dry food transport, and reinforced fish-specific boxes handle this better than standard general-purpose thermocol boxes.

Practical consideration: bulk/wholesale seafood operations often benefit from Hi-D (high-density) reusable grade boxes rather than disposable, given the frequency and volume of repeated shipments, the higher upfront cost pays back quickly at commercial shipping volume.

Pharmaceutical & Medical

Typical size range: Small to medium, precision-matched to shipment

Pharmaceutical shipping, vaccines, insulin, general medicine, blood samples, has the tightest requirements of any category covered here, since temperature stability during transit is a genuine patient-safety issue, not just a product-quality concern. Box sizing here should be matched precisely to the actual shipment volume rather than oversized, since excess air space inside a box can actually reduce cold-retention efficiency compared to a properly sized box with adequate ice packs or gel packs.

Practical consideration: this category most benefits from consistent, quality-controlled box sourcing, the cost difference between a reliable supplier and an unreliable one matters more here than in lower-stakes categories, given what's at risk if temperature control fails during transit.

Dairy Products

Typical size range: Medium (5-30L)

Milk, butter, cheese, and yogurt transport particularly benefits from insulated thermocol packaging during Pakistan's hot summer months, when the gap between "safely chilled" and "spoiled" narrows considerably during transit time. Dairy distributors typically need a size range that scales with delivery route volume, smaller boxes for direct-to-consumer delivery, larger for retail/wholesale distribution runs.

Practical consideration: dairy transport often benefits from boxes specifically designed to work well with ice packs or dry ice depending on the product and required temperature range, confirm with your supplier which grade suits your specific dairy product line.

Ice Cream & Frozen Goods

Typical size range: Medium to bulk, paired with dry ice

Frozen product transport, particularly ice cream, requires sub-zero temperature maintenance that standard ice-pack cooling can't achieve, meaning these boxes are typically used in combination with dry ice for genuinely effective sub-zero performance during extended transit times.
