Popular Perishables You Can Ship by Mail — And How to Ensure They Arrive Safely

Shipping perishable items through the mail doesn’t have to be risky — if you use the right packing materials and proven methods. At LoBoy Coolers, we help businesses and individuals ship perishables safely across the country using high-performance styrofoam shipping coolers and cold packs engineered for long-lasting thermal protection.

Why Use Styrofoam Coolers for Shipping Perishables?

• Thermal Insulation: Expanded Polystyrene (EPS) maintains internal temperatures for extended periods.
• Durability: LoBoy coolers are designed to resist crushing, cracking, and moisture damage in transit.
• Carrier Approved: Major carriers like USPS, UPS, and FedEx recommend styrofoam shipping coolers inside corrugated boxes.

With the right setup, your perishables can arrive fresh, intact, and on time — even in the middle of summer.

What Perishables Can You Ship?

Some of the most common perishables shipped in LoBoy coolers include:

• Fresh & Frozen Seafood
• Steaks, Poultry, and Specialty Meats
• Cheeses and Dairy Products
• Prepared Meal Kits and Subscription Boxes
• Live Plants and Flowers
• Pharmaceuticals and Temperature-Sensitive Medications
• Specialty Beverages (like wine, cold brew, or kombucha)

The 6 Essential Components of a Safe Perishable Shipment

1. LoBoy Styrofoam Cooler: Choose the right size and wall thickness based on your temperature and transit time needs.
2. Coolant: Use gel packs for chilled items or dry ice for frozen goods. Always follow shipping regulations for dry ice.
3. Leak Protection: Use waterproof bags, liners, and absorbent materials to prevent any moisture from leaking.
4. Corrugated Outer Box: Place the foam cooler inside a strong, properly sized outer shipping box and seal using the “H-tape” method.
5. Stabilizing Dunnage: Use crumpled paper or foam peanuts around the cooler to prevent shifting and add insulation.
6. Proper Labeling: Clearly mark your box with “PERISHABLE,” and include handling instructions. If using dry ice, label with “UN1845” and net weight.

Should You Use Gel Packs or Dry Ice?

Use Gel Packs When Shipping Chilled Goods:

• Maintain a range of 34–50°F
• Non-toxic and reusable
• Safer and easier to handle than dry ice

Use Dry Ice When Shipping Frozen Goods:

• Maintain temperatures below 0°F
• Required for products like frozen meats, ice cream, or vaccines
• Requires proper ventilation and hazmat labeling
