FAQs for Insulated Shipping Containers

Are KoolTemp molded EPS containers recyclable?

Yes, KoolTemp molded EPS containers are recyclable. In the broadest sense, EPS is a 100% recyclable lightweight rigid cellular plastic that containers 98% air. It is completely inert. For a detail review of EPS and the environment, please visit our manufacturer partner’s website, Foam Fabricators, Inc. Click here for Foam Fabricator’s recycling brochure.EPS may be brought to designated drop-off locations, recycling centers that accept polystyrene (#6), or sent to mail-back locations.

Are KoolTemp PUR containers reusable?

Yes, assuming that the molded PUR insert has not been damaged during a previous shipment. The outer corrugate box must be replaced. To determine the number of times that a PUR container may be reused, an internal quality program should be implemented to monitor physical integrity.

Which KoolTemp™ containers are best suited to each of the following shipping situations?

  • Valuable payloads that require 2°C to 8°C protection during demanding shipping conditions - choose KoolTemp PUR Polyurethane Insulated Containers. These environmentally conscious (non ozone-depleting) containers feature modular design that allows for easy packout, replacement of corrugate for reuse, and recycling.
  • Temperature-sensitive applications - choose KoolTemp EPS Molded Insulated Containers, offered in a variety of thicknesses; or KoolTemp EPS Panel Sheet Insulated Containers: space-saving, durable and efficient thermal protection in a variety of styles lined with lightweight, precision-cut expanded polystyrene (EPS).
  • Pallet-sized loads - choose KoolTemp Insulated Pallet Containers, which provide excellent, uniform thermal protection with extruded polystyrene (XPS, also abbreviated as EXP) and sleeves of Koolit Refrigerant Bricks.
  • Small, temperature-sensitive products - choose KoolTemp Insulated Envelopes, lightweight, durable, thermal insulated envelopes designed with a spacious payload chamber for your temperature-sensitive articles, and our Koolit Gel Paks.
  • Pre-qualified shipping systems - choose from among Cold Chain's pre-qualified KoolTemp shipping solutions that provide many hours of thermal protection for temperature-sensitive products.

What factors should I consider when choosing insulation?

Many factors influence your choice of insulation, including:

  • acceptable temperature range and excursions;
  • external ambient temperatures during shipment;
  • shipping method, duration, and costs;
  • size, dimensional weight, and ergonomic requirements; and
  • budget.

Contact our experienced staff at Cold Chain for assistance in this decision making process.

What are the R-value and K-value, and how do they help me choose the best insulation for my packaging needs?

The R-value is a measure of thermal resistance, or a material's ability to prevent heat loss. A higher R-value correlates with a greater ability to prevent heat loss. The K-value is a measure of thermal conductivity that is calculated by dividing insulation thickness by its R-value. When the R-value is high, the corresponding K-value is low.

Since the cost of insulation increases with R-value, a cost-benefit analysis is always required to choose the best insulation for a specific application. Listed below is a summary of R-value by type of insulation. These values are general guidelines based on one-inch thick insulation.

What's the difference between Cold Chain's EPS and XPS (EXP) containers?

EPS (expanded) and XPS (extruded) are different types of manufactured polystyrene. The EPS is formed by molding tiny pellets of polystyrene. It's used in our molded and panel-sheet insulated containers, and provides lightweight, cost effective thermal protection (R-value = 4 per 1"), and enhanced drop cushioning properties. XPS (EXP) is formed by an extrusion process of polystyrene. It's used in our pallet containers, which offer excellent, uniform thermal protection (R-value = 5) for large payloads.

How do I choose the right thickness of insulation?

In addition to choosing the appropriate container size and type of insulation, wall thickness is also an important consideration. Generally, chilled products sent next day or overnight that need to stay cool will arrive satisfactorily using ½" to 1" thicknesses of insulation. Longer duration shipments (two days or more) and more exacting maintained temperatures will require a thicker wall of insulation (1-½" to 2").

Once I've chosen the type of my KoolTemp Container and Koolit Refrigerants, how do I determine the best fit for my product?

See Simple Packout Guidelines.

Do I need to fill in empty spaces in my packed container?

Yes, to minimize heat loss, fill voided space with dunnage (bubblewrap, newspaper, etc.). This reduces the chance of heat pockets forming in empty air channels surrounding a product. It also provides additional protection from movement within the shipping container during transit.

Are KoolTemp insulated shipping containers environmentally safe?

Yes, KoolTemp containers do not contain CFCs and HCFCs, which are known to reduce atmospheric ozone. EPS may be reclaimed for reuse according to local regulations. EPS may be safely combusted; it releases water vapor, carbon dioxide, and trace levels of ash.

What are MSDS sheets?

MSDS, or Material Safety Data Sheets, provide health, safety, spill, and response information to the Occupational Safety and Health Administration (OSHA) on identified harmful substances.

How should I label my container?

Label the top of the box to ensure that it is shipped upright.
