Polystyrene boxes

Polystyrene boxes are used for transporting temperature sensitive goods that need protection and insulation during shipping. Made from expanded polystyrene, these containers provide excellent insulation while remaining lightweight and cost effective for regular delivery.

At Kite Packaging, our range of EPS boxes includes standard and premium options designed for temperature controlled packaging. Sizes, litre capacities and dimensions in mm are listed in the product tables above, helping you choose the right boxes for your products before you order.

Polystyrene Boxes for Temperature Sensitive Goods

Polystyrene boxes are widely used to transport temperature sensitive products across industries such as food distribution and pharmaceutical delivery. Their insulation helps maintain stable conditions during shipping and transit, particularly when used with ice packs.

These EPS boxes are ideal for sending:

• Fresh food such as seafood, meat and dairy
• Chilled food deliveries
• Pharmaceutical products
• Medical samples
• Other temperature sensitive goods

The insulating properties of expanded polystyrene help protect contents from temperature changes during delivery. This makes EPS boxes a reliable option for temperature controlled packaging within the cold chain.

Expanded Polystyrene Boxes and Insulation Properties

Expanded polystyrene is created through a process where polystyrene beads expand using heat. The result is a lightweight foam structure made mostly of air, which gives EPS its great insulating properties.

Because of this structure, polystyrene boxes provide:

• Excellent insulation for temperature sensitive products
• Shock absorption to protect goods during transit
• Lightweight packaging that helps keep shipping efficient
• Moisture resistance that helps prevent humidity damage

These insulation properties make expanded polystyrene boxes suitable for transporting food, pharmaceuticals and other temperature sensitive products that require temperature controlled shipping.

Standard and Premium EPS Boxes for Temperature Controlled Packaging

Our range of polystyrene boxes includes both standard and premium EPS boxes, allowing you to choose the right level of insulation for your products.

• Standard boxes have a 20mm wall thickness and are suitable for many temperature sensitive goods.
• Premium boxes have a 60mm wall thickness for increased insulation during longer delivery times.

When used with ice packs or gel packs, these boxes can help maintain temperature controlled conditions for chilled products during shipping and transit.

Sizes, Litre Capacities and Dimensions

The product tables above list the full range of expanded polystyrene boxes available, including their litre capacity and dimensions in mm. This information helps you choose the correct box size before shipping your products.

Within the tables you can view:

• Internal and external dimensions in mm
• Litre capacity of each box
• Polystyrene wall thickness
• Units per pallet and price breaks

Clear dimensions allow you to compare sizes and select polystyrene boxes that suit your products and packaging requirements.

EPS Box Sets with Cardboard Outer Shipping Boxes

Some expanded polystyrene boxes in this range are supplied as box sets that include a cardboard outer. The EPS box sits inside the outer carton, providing extra protection during shipping and delivery.

These sets are useful for temperature controlled packaging where additional protection during transit is required.

They provide:

• Insulated EPS boxes for temperature sensitive products
• A cardboard outer for easier shipping and handling
• Added protection for goods during delivery
• A practical option for cold chain shipments

Recycling and Sustainability of Polystyrene Packaging

Expanded polystyrene is 100 recyclable and CFC free. The material can be recycled through specialist EPS recycling facilities in the UK.

Most local councils do not currently accept polystyrene in household recycling bins, as it can be difficult to sort and process. Businesses and end users should check local guidance to confirm available recycling options.

EPS packaging remains widely used because it combines insulation, lightweight structure and cost effective temperature controlled packaging.

Frequently Asked Questions

Below are answers to common questions about our polystyrene boxes, including insulation, recycling and how they are used for temperature controlled packaging.

What are polystyrene boxes used for?

Polystyrene boxes are used to transport temperature sensitive goods that require insulation during shipping and delivery. Expanded polystyrene boxes are commonly used for food, pharmaceuticals and other temperature sensitive products where stable conditions are needed during transit.

What is expanded polystyrene?

Expanded polystyrene, often called EPS, is a lightweight foam material made by expanding polystyrene beads using heat. The process creates a structure made mostly of air, which gives EPS boxes their great insulating properties and excellent insulation for temperature controlled packaging.

Do polystyrene boxes keep products cold?

Yes. Polystyrene boxes help insulate temperature sensitive products during shipping. When used with ice packs or coolants, EPS boxes can maintain temperature controlled conditions for chilled goods and other temperature sensitive products.

Can polystyrene boxes be recycled?

Yes. Expanded polystyrene is 100 recyclable and can be processed through specialist recycling facilities in the UK. However, most local councils do not accept polystyrene in standard household recycling, so users should check local guidance.

What is the difference between standard and premium EPS boxes?

Standard EPS boxes have a 20mm wall thickness, while premium boxes use 60mm thick expanded polystyrene. The thicker walls provide increased insulation, making premium polystyrene boxes suitable for longer delivery times or highly temperature sensitive goods.

Do EPS boxes come with a cardboard outer box?

Some products in the range are supplied as EPS box sets that include a cardboard outer. The outer carton helps protect the insulated box during shipping and delivery while supporting temperature controlled packaging requirements.
