Insulated Shipping Kits with Ice Packs for Temperature-Sensitive Products
Shipping temperature-sensitive products through standard carrier networks without cold chain protection is a liability. Heat exposure during summer ground transit can compromise wine quality, damage food products, and result in returns that cost more than the original shipment.
Gorilla Shipper’s insulated shipping kit addresses this as a system. The Hexabox outer carton provides structural protection, and prevents bottle movement.The Coldliner Insulated Insert seals the interiors because of which there is a thermal barrier between the product and heat out there. The No-Sweat Cold Pack maintains refrigerated temperature throughout the transit window without condensation or label damage. All three components are tested together to the ISTA-7D 48-hour summer heat profile, which simulates peak summer ground shipping conditions across US carrier networks. The kit is FedEx and UPS approved and built entirely from sustainable materials.
Coldliner Insulated Insert: Foam-Free Protection for Glass Bottles
The Coldliner Insulated Insert (HS401) is Gorilla Shipper’s sustainable alternative to foam insulation for glass bottle shipping. Made from 100% recyclable LDPE, it fits inside both Short and Standard Hexabox Shippers and is designed for 750ml bottle formats.
Where standard foam shippers rely on bulky polystyrene that’s difficult to dispose of and restricted from disposal in several US states, the Coldliner uses a lightweight insulated liner that protects against both summer heat and winter freezing year-round. It stores flat, assembles fast, and eliminates the end-of-life disposal problem that foam creates for customers. Sold in units of 100 with volume pricing starting from $1.23 per unit across Bronze, Silver, and Gold tiers.
No-Sweat Ice Packs for Shipping in Summer Heat
Standard gel packs sweat. The condensation soaks into corrugated walls, weakens the box structure, and damages labels before the package reaches the customer. Gorilla Shipper’s No-Sweat Cold Pack (IP08) eliminates that problem entirely.
The outer film is engineered to contain moisture rather than release it, so the corrugated carton stays dry, labels stay intact, and the product arrives in the condition it left. The No-Sweat Cold Pack pairs directly with the Coldliner Insert and Hexabox Shipper to form a complete heat-protection system for glass bottle shipping during warm months. It’s reusable, sweat-proof, and designed specifically for temperature-sensitive shipments through standard FedEx and UPS networks. Sold in units of 66 with volume pricing from $0.60 per unit.
Gel Packs for Shipping vs Dry Ice: Choosing the Right Cold Source
Gel packs and dry ice serve different temperature ranges and come with very different carrier requirements.
Gel packs for shipping maintain refrigerated temperatures, starting from 32°F to 60°F. They are non-hazardous, require no special labeling, and ship via any FedEx, UPS, or USPS service without carrier restrictions. For wine, food, and beverage brands shipping products that need to stay cool rather than frozen, gel packs are the practical and operationally simpler choice.
Dry ice maintains sub-zero temperatures and is the right option for fully frozen goods. But it is classified as a hazmat material under DOT 49 CFR 173.217, requires UN1845 labeling on two exterior sides of the package, and carries carrier-specific restrictions on volume per shipment for air services. For most wine and beverage brands, the compliance burden of dry ice is unnecessary. The product doesn’t need to stay frozen. It needs to stay below 60°F. That’s exactly what ice gel packs shipping with the Coldliner system delivers, without the hazmat paperwork.
Cold Chain Shippers for Wine & Beverage Brands
Wineries and DTC beverage brands have a specific cold chain requirement. Wine needs to stay below 60°F during summer ground transit to avoid heat damage. Standard corrugated boxes with no insulation can’t achieve that. Standard foam shippers can, but they create disposal problems for customers and perform inconsistently once the foam compresses under carrier handling.
Gorilla Shipper’s Hexabox plus Coldliner Insert plus No-Sweat Cold Pack system
was independently tested to the ISTA-7D 48-hour summer heat profile by Insulated Products Corporation. The results: the Coldliner system maintained safe wine temperature for 7 hours 55 minutes before reaching the 60°F threshold. Standard ULINE foam reached the same threshold at 6 hours 35 minutes. That’s an 80-minute performance advantage under identical summer heat conditions, without using foam. For kombucha producers, non-alcoholic beverage brands, and specialty food brands shipping olive oil or prepared foods that degrade in heat, the same system applies. A complete cold chain shipper that performs better than foam, ships cleaner, and disposes of cleanly on the other end.
Who Uses Gorilla Shipper’s Coldliner Inserts & Ice Packs
Gorilla Shipper‘s insulated shipping kits are used across a range of temperature-sensitive product categories.
Wineries and DTC wine retailers use the full kit for summer ground shipments where maintaining wine below 60°F is the primary requirement. Craft distilleries shipping spirits that require temperature stability during transit use the same system.
Non-alcoholic beverage brands and kombucha producers shipping live cultures or carbonated products that degrade in heat need Coldliner and No-Sweat Cold Pack. The reason? To maintain product integrity. In fact specialty food and olive oil brands use it for premium perishable products. This actually helps them with the heat exposure that may deteriorate the product quality. Meal kit companies shipping prepared or semi-prepared food through standard carrier networks use the system as a cost-effective alternative to dedicated cold chain freight. Corporate gifting brands shipping temperature-sensitive products to business recipients use it to ensure the product arrives in presentable condition regardless of summer transit conditions.
Sustainable Alternative to Styrofoam Shipping Coolers
Styrofoam shipping coolers are the industry default for cold chain protection and the most problematic material to dispose of. EPS foam is banned from disposal in California, New York, and several other US states. It’s not curbside recyclable in most US markets. And it arrives at the customer’s door as a disposal problem they didn’t ask for.
Gorilla Shipper’s Coldliner Insert is made from 100% recyclable LDPE, printed with the #4 recycle symbols, and curbside recyclable in most areas. The Hexabox outer carton is made from 100% post-consumer waste corrugated. There is no polystyrene in the system at any point. The entire kit is recyclable end to end. And unlike styrofoam shipping coolers, it’s ISTA 6-FedEx-A certified and independently tested to outperform foam under the ISTA-7D summer heat profile. The sustainable option is also the better-performing one.
Frequently Asked Questions About Ice Packs & Insulated Shipping Kits
What are ice packs for shipping and how do they work?
They’re frozen gel packs that go inside a shipping box to keep products cold during transit. The gel absorbs ambient heat and stays cold long enough to protect the product through the shipping window.
What is the difference between the Coldliner Insert and the No-Sweat Cold Pack?
The Coldliner is the insulated LDPE liner that wraps around the bottle and creates the thermal barrier. The No-Sweat Cold Pack is the frozen gel pack that handles the active cooling, both work as a system.
What is the difference between gel packs and dry ice for shipping?
Gel packs maintain temperatures between 32°F and 60°F and ship through any carrier without special labeling. Dry ice goes sub-zero but needs DOT hazmat compliance and UN1845 labeling on air shipments.
How long do gel packs keep products cold during shipping?
In ISTA-7D testing, Gorilla Shipper’s kit kept wine below 60°F for 7 hours 55 minutes under 48-hour summer heat conditions. Actual performance depends on ambient temperature and transit duration.
How many ice packs do I need per shipment?
One No-Sweat Cold Pack per bottle is the standard with the Coldliner and Hexabox setup. Add another if you’re shipping in peak summer heat or across a longer transit window.
Can I ship gel packs via FedEx, UPS, or USPS without special labeling?
Yes, gel packs are non-hazardous and go through FedEx, UPS, and USPS with no special labeling or carrier restrictions.
Do dry ice packs for shipping require hazmat labeling?
Yes, dry ice is a Class 9 hazmat under DOT 49 CFR 173.217 and needs UN1845 labeling on two exterior sides of the package for air shipments.
What temperature range do Gorilla Shipper’s insulated kits maintain?
The Coldliner and No-Sweat Cold Pack system maintains between 32°F and 60°F, which covers the safe shipping range for wine, most beverages, and temperature-sensitive food products.
How does a styrofoam shipping cooler compare to the Coldliner insulated insert?
In ISTA-7D testing, the Coldliner held safe wine temperature for 7 hours 55 minutes versus 6 hours 35 minutes for standard ULINE foam. And unlike foam, the Coldliner is fully recyclable.
Are Gorilla Shipper’s Coldliner inserts and ice packs recyclable?
The Coldliner is 100% recyclable LDPE, curbside recyclable in most areas, and the Hexabox is made from 100% post-consumer waste corrugated. No foam anywhere in the system.
What is an ISTA-7D summer heat profile test?
It’s a standardized test that simulates summer ground shipping conditions over 48 hours with ambient temperatures cycling up to 95°F. It’s the benchmark for validating cold chain packaging under peak US summer transit conditions.
Can I use the No-Sweat Cold Pack for shipping wine in summer?
Yes, it’s built for exactly that. It pairs with the Coldliner and Hexabox to form a complete heat-protection system for wine and beverage shipments in warm months.
What bottle sizes does the Coldliner insulated insert fit?
The Coldliner (HS401) is sized for 750ml bottles and fits inside both Short and Standard Hexabox Shippers.
Do I need both the Coldliner insert and ice pack or can I use one alone?
You need both. The Coldliner handles insulation and the No-Sweat Cold Pack handles active cooling, using one without the other reduces the thermal performance of the system.
Are Gorilla Shipper’s insulated shipping kits FedEx and UPS carrier approved?
Yes, the full kit, Hexabox, Coldliner Insert, and No-Sweat Cold Pack, is FedEx and UPS approved and ISTA-certified for carrier network compliance.
