The temperature threats that cargo faces during ocean shipping are far more severe than most people imagine. During the day, the sun continuously heats the metal container, and internal temperatures can reach as high as 55-70°C. At night, temperatures drop sharply; the hot, humid air inside condenses into water droplets that fall from the ceiling , thus "container rain," a headache for countless cargo owners.
Severe day-night temperature differences repeatedly cause a destructive cycle of expansion, contraction, and moisture condensation inside the container.
Many cargo owners often underestimate temperature risks during transit, only regretting it when they receive buyer claims.
Temperature damage brings not only the loss of the cargo itself but also: logistics costs for re-shipment, buyer claims and customer loss, compliance audits, and brand image damage.
Overheating and spoilage of container cargo can cause losses of hundreds of thousands of yuan. A batch of electronic components failing due to thermal expansion and contraction can result in return and claim costs that are even more difficult to estimate.
Food softening, chocolate melting and clumping, coffee beans becoming damp and losing flavor, medicines failing, electronic devices being damaged, cosmetics separating and degrading, etc. The resulting cargo damage amounts to hundreds of millions of dollars every year.
Temperature protection is not optional , it is essential.
HeatGUARD is a professional brand under T&S Group focusing on container thermal insulation, offering a systematic solution developed specifically for container insulation scenarios.
Defend Against All Three Types of Heat Transfer
Radiant heat, conductive heat, and convectional heat are the three primary causes of container temperature rise. HeatGUARD's aluminum foil composite material reflects 95% of radiant heat. The unique installation method creates an insulating air layer between the container wall and the cargo to block conductive heat. The sealed liner environment effectively suppresses airflow to block convective heat. This three-pronged approach is industry-leading.
Significant Temperature Control Results
Test data shows: When the summer outdoor temperature is 36°C, a standard container can reach 55-60°C internally. With HeatGUARD, the internal temperature can be controlled to 40-45°C , a reduction of 10-15°C. Using the liner bag together with the pallet cover further doubles the effect.
Thin, Lightweight, and Easy to Install
The 7 layer aluminum foil composite material is thinner, lighter, and stronger than traditional bubble film and EPE materials. It is easy to install, recyclable after use, and environmentally friendly.
Full-Scenario Compatibility
Widely used in ocean shipping scenarios for temperature-sensitive cargo such as food, beverages, chocolate, coffee, pharmaceuticals, chemicals, cosmetics, electronics, and aerospace. Compatible with 20GP, 40GP, 40HQ standard containers, and various pallet sizes.

View MoreHeat invades the container in three ways: radiation (direct sunlight), conduction (heat transferring through the metal container walls), and convection (hot air circulating inside the container).
The highly reflective aluminum foil surface of the HeatGUARD liner reflects 95% of radiant heat back to the container. During installation, an air layer is retained between the liner and the container wall, creating an insulating buffer zone that blocks conductive heat transfer. Once the liner is sealed, air cannot flow freely, completely cutting off convective heat.
All three mechanisms work simultaneously, keeping the internal temperature within a controllable range and ensuring cargo quality throughout the entire journey.
What types of cargo is HeatGUARD suitable for?
It is widely suitable for cargo that requires temperature protection, including temperature-sensitive categories such as food, beverages, chocolate, coffee, tea, pharmaceutical products, cosmetics, chemical materials, and electronic products.
How many liner sets are needed per container?
Typically, one liner set of the corresponding specification is sufficient for complete protection in a 20GP or 40GP container. For a higher level of protection, it can be used together with the HeatGUARD pallet cover.
Can the liner be reused?
Yes. The HeatGUARD material has high strength and is not easily damaged during normal use, installation, or removal. It can be reused multiple times, reducing the cost per use.
Are professional tools required to install the HeatGUARD liner?
No. The liner is designed for simplicity and can be installed by one person without any professional tools. Just follow the installation instructions for quick setup.
Can using only desiccants solve temperature problems?
Desiccants primarily solve moisture problems and cannot effectively block temperature rise. HeatGUARD is specifically designed for temperature control. Using both together addresses the dual risks of temperature and humidity, providing the most comprehensive protection for your cargo.
