Short Description

BULK-FLOW’s thermal container liners protect heat-sensitive cargo from extreme heat or extreme cold temperatures.

BULK-FLOW’s thermal container liners offer two degrees of protection through its product range of radiant barrier liners and reflective insulation liners.

BULK-FLOW’s thermal radiant barrier liners provide protection from an extreme heat average of – 10° C (-18°F) or from an extreme cold average of +8°C (+14°F)

BULK-FLOW’s thermal reflective insulation liners provide protection from an extreme heat average of – 24.5° C (-44°F) or from an extreme cold average of +20°C (+36°F)

Features

MULTI-LAYER COMPOSITE CONSTRUCTION – Our thermal container liners are made from a multi-layer composite material that may include aluminum foil, HDPE film, PET, bubble wrap, and/or other materials.

PROTECTION FROM HEAT – High temperatures within a container can trigger the self-heating or spontaneous combustion of certain temperature-sensitive commodities. Likewise, when temperatures reach a certain level, commodities may over-ferment and release corrosive gases. Our thermal container liner prevent this crisis by shielding cargo from radiant heat and UV light.

FIRE RETARDANT – BULK-FLOW’s thermal container liners are made from flame-retardant material to reduce flammability and prevent damage to cargo.

PROTECTION FROM MOISTURE – Temperature-sensitive commodities may sustain moisture and/or mold damage when temperature changes cause condensation to form inside of the container. Our thermal liners help prevent significant changes in the internal temperature of the container, to reduce the risk of damage. For maximum effectiveness, BULK-FLOW thermal container liner can be used in conjunction with desiccant bags, which absorb internal humidity and further reduce the chances of molding.

Detailed Description

There are three modes of heat transfer: CONDUCTION, CONVECTION, and RADIATION (INFRARED). Of the three, radiation is the primary mode; conduction and convection are secondary and come into play only as matter interrupts or interferes with radiant heat transfer.

All substances, including air spaces transfer heat. Only the heat transfer rate changes depending on the differences in density, weight, shape, permeability and molecular structure.

Heat is radiated and conducted in all directions by all objects, but convected primarily upward. The infrared rays travel at the speed of light as energy and have no temperature. Only when these rays strike the surface of an object or matter, the rays are absorbed and only then the heat is produced in the object. The heated object then transmits infrared rays from exposed surfaces by radiation if these surfaces are exposed directly to an air space.

The amount of radiation emitted is a function of the EMISSIVITY factor of the source´s surface. EMISSIVITY is the rate at which radiation is given off.

Most materials used in construction have absorption and emissivity rates from 80% to 93%.

Conversely the surface of ALUMINIUM has the ability NOT TO ABSORB, but TO REFLECT 95% of the infrared rays which strike it.

Additionally, since aluminum foil has such a low mass to air ratio, very little CONDUCTION can take place, particularly when only 5% of the rays are absorbed.

1. BULK-FLOW’s Thermal Radiant Barrier Liners

It provides protection from an extreme heat average of – 10° C (-18°F) or from an extreme cold average of +8°C (+14°F).

It is composed of an aluminum double-sided foil and an internal sandwiched woven layer for strength.

It hangs in marine shipping containers and allows forklift traffic. Once loaded, it is sealed off on the door side to protect the cargo from extreme temperatures, humidity and fire.

Cargo inside of a container penetrates through the container wall from outside via infrared radiation. The heat from the walls is transferred into the circulating air inside of the container by convection.

The aluminum foil reflects 97% of the radiant heat, and the fully enclosed liner prevents the air from spreading the heat by convection.


2. BULK-FLOW’s Thermal Reflective Insulation Liners

It provides protection from an extreme heat average of – 24.5° C (-44°F) or from an extreme cold average of +20°C (+36°F)

It is composed of an aluminum double-sided foil and an internal layer of air bubbles. In addition to the benefits of the radiant barrier liners, the air bubbles reduce the heat transfer in a number of ways: Radiation is the primary mode; conduction and convection are secondary and come into play only as matter interrupts or interferes with radiant heat transfer.

As matter absorbs radiant energy, it is heated and a gradient temperature develops, which results in molecular motion

  • The bubbles of trapped air between the 2 foils help reduce heat distribution through convection.
  • The bubbles minimize heat transmission through conduction between the 2 layers of foil

It hangs in marine shipping containers and allows forklift traffic. Once loaded, it is sealed off on the door side to protect the cargo from extreme temperatures, humidity and fire.
