The BPI Integrated Liner is a prefabricated passive thermal insulation liner for standard dry freight containers. It is supplied internationally for installation by shippers or local installation partners where available. Installation typically takes 7 to 20 minutes depending on container size. The liner helps reduce heat transfer and moderate temperature fluctuations but does not actively heat, cool or maintain a fixed cargo temperature.
Key Takeaways
- Prefabricated liner for 20ft, 40ft, 40ft HC and 45ft containers.
- Five-layer laminate of metallised polyester film and high-density polyethylene woven fabric, as specified for the 40ft HC with-floor liner.
- Installation typically takes 7–20 minutes, depending on container size.
- Suitability depends on the cargo's documented temperature requirements, loading conditions, route, season and transit duration.
What Is the BPI Integrated Liner?
The BPI Integrated Liner is a prefabricated thermal container liner designed for exporters, manufacturers, freight forwarders and logistics providers shipping in standard dry freight containers. It is manufactured to suit the selected container size rather than being assembled on site from individual insulation panels, framing or separate vapour barriers.
It is distinct from BubblePack's Roll Liner, which is primarily supplied and professionally installed by BubblePack's own technicians in Ireland.
How Does Passive Thermal Insulation Work?
Passive insulation helps reduce heat transfer between the container shell and the cargo space. The 40ft HC with-floor Integrated Liner specification lists radiant heat reflectivity of 95–97% for its metallised material surfaces. This material property is not a percentage reduction in cargo temperature.
The liner does not heat or cool cargo or maintain a fixed setpoint. Insulation may help reduce conditions contributing to condensation, but it cannot guarantee condensation prevention or a particular temperature outcome.
Integrated Liner Features and Container Coverage
The Integrated Liner is supplied in prefabricated configurations for common dry freight container sizes. Coverage depends on the selected liner configuration, including whether floor protection is included.

BubblePack has used temperature loggers on live commercial shipments to examine conditions on particular routes. Such records are shipment-specific and do not guarantee the outcome of another shipment. See the BPI Integrated Liner product page for further information.
Installation and Supply Options
The Integrated Liner can be supplied internationally for installation by the shipper or through local installation partners where available. Availability, site access and fitting arrangements should be confirmed for each location and booking.
- Confirm the container size and liner configuration before ordering.
- Arrange delivery to the agreed warehouse, depot or loading location.
- Fit the prefabricated liner in accordance with the supplied installation guidance.
- Allow typically 7–20 minutes for fitting, depending on container size, and coordinate the work before loading.
Which Cargo Types May Benefit?
Potential applications include temperature-sensitive cargo in the sectors BubblePack serves. Suitability is not automatic and should be assessed for each shipment.
Dairy and milk powder
Products where heat and moisture exposure may affect cargo or packaging quality.
Food ingredients
Ingredients with documented temperature or moisture sensitivity.
Wine, spirits and beverages
Shipments where heat or freezing exposure could affect product quality.
Pharmaceuticals and life sciences
Pharmaceutical shipments require documented temperature requirements and appropriate shipper qualification. Passive insulation is not a substitute for required active temperature control.
Chemical and industrial ingredients
Suitable products requiring assessment of temperature and moisture exposure during transit.
Consider the cargo's temperature limits, loading conditions, route, season and transit duration before choosing a liner.
Integrated Liner vs Refrigerated Containers
Refrigerated containers provide active temperature control when suitably powered, including through generator sets. The Integrated Liner provides passive insulation only. On suitable routes, thermal liners can offer 40–60% lower shipping costs than refrigerated containers, depending on cargo and transport requirements. This is not a guarantee of equivalent temperature control.
Where a product requires a controlled temperature setpoint, suitably qualified refrigerated equipment remains the appropriate option.
What Information Is Needed for a Quotation?
- Container size: 20ft, 40ft, 40ft HC or 45ft.
- Cargo type and documented temperature requirements.
- Origin, destination, route, season and expected transit duration.
- Delivery or installation location and required date.
- Quantity and expected ongoing volume, where relevant.

Frequently Asked Questions
What is an Integrated Liner?
A prefabricated thermal container liner designed to provide passive insulation inside a dry freight shipping container.
How long does installation take?
Typically 7–20 minutes, depending on container size.
Can it be installed without BubblePack's team on site?
Yes. Shippers can fit the prefabricated liner using the installation guidance, or fitting can be discussed through local partners where available.
Which container sizes does it suit?
20ft, 40ft, 40ft HC and 45ft. Coverage depends on the configuration selected.
Does the liner heat or cool cargo?
No. It is passive insulation and does not actively heat, cool or hold a fixed temperature.
Does it prevent condensation?
It may help reduce conditions contributing to condensation but cannot guarantee prevention.
How does it differ from the Roll Liner?
The Integrated Liner is prefabricated for international supply. The Roll Liner is a separate system primarily supplied and professionally installed by BubblePack in Ireland.
