THERMAL LINER FOR TRANSPORTING GOODS

Abstract

A thermal liner relates to the field of thermal insulation in the transportation of freight, and comprises a heat-insulating material, in which the components are hermetically connected to each other, wherein the liner matches the inner shape of a container, has a front wall that opens, and has fastening elements along an upper perimeter, which are designed to allow the insert to be fastened in a container using a cord and inner eyes of the metal container, wherein the thermal liner is made of a combination of materials, and the heat-insulating material used is metallized, laminated, expanded polyethylene and black polyethylene film which provides the required temperature difference between the outside temperature and the inside temperature, and helps lower the thermal conductivity

BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The invention is illustrated by drawings as follows:

DETAILED DESCRIPTION OF THE INVENTION

[0026] The liner 1 repeats the inner shapes of the container 2; it has a front wall that opens 3, and the eyelets 4 are made along the upper perimeter with the possibility of fixing the liner in the container using a mounting cord 5 and the inner lugs 6 of the metal container. At that, the thermal liner is made of a set of materials, and laminated metallized polyethylene foam (PE foam) 7 with light-reflecting and heat-shielding ability 8 as the thermal insulating material and a black polyethylene film 9 to ensure that the cargo in a metal container does not respond to ultraviolet radiation, sunlight, so that it is isolated from the penetration of cold or hot air, and does not subjected to sudden temperature changes that occur during container transportation across different continents, as well as temperature differences day/night, are used.

[0027] The thermal liner is used in this way. In order to install the liner, you must unfold the liner and fix the upper part of the side walls with angular cords (tapes, twine) at the lugs (loops) of the container. After that, it is necessary to fix the lower part of the side walls of the liner with the help of angular and longitudinal cords (tapes, twine) in the lugs (loops) of the container. After fixing the angular and longitudinal tapes, you must insert the mounting cords (tapes, twine) into the lugs (loops) of the container and the grommet of the liner and fix them on the last lug (loop) of the container.

[0028] Thermal insulation is achieved in this way. The metallized film with a reflective effect (deposition of a film with an aluminum or light-reflecting paint, or by using a thin layer of aluminum) is a light-reflecting layer.

[0029] Polyethylene foam serves as an air barrier with a heat-shielding function, slowing down the action of sudden heating or cooling the temperature inside the container.

[0030] The black plastic film serves as UV protection. One of its properties is also thermostability.

[0031] The outer layer of the liner is made of polyethylene foam, laminated on one side with a reflective PET film, and a black opaque film is used as the inner layer.

[0032] In order to prevent the penetration of air and the formation of condensate inside the liner during transportation, the thermal liner is produced by heat sealing of the tnaterial.

[0033] Thus, the invention provides the composition of the material for the thermal liner, which provides the desired temperature difference between the external and internal temperatures and reduces the thermal conductivity of the product
