- The present invention relates to a material for packaging applications, more particularly, to an insulating and light reflective material that can be used to manufacture insulating containers.
- 2) Description of the Prior Art
- Since an important proportion of edible perishables are transported from their production site to a consummation site, containers have been developed with insulating properties. It is highly desirable to use a lightweight container material to reduce the transportation costs. The container material must also be strong enough to safely carry the perishable goods, inexpensive, and, preferably, fully recyclable for environmental concerns.
- Honeycomb materials, consisting of a honeycomb core laminated between to linerboards as face members, are well-known for their heat insulating properties due to their numerous individual dead air space cells. They are also lightweight materials since, as mentioned above, they contain mainly air space cells. Moreover, their mechanical properties are often superior to the mechanical properties of other lightweight materials. Honeycomb materials probably offer the best strength to weight ratio of any material available. Honeycomb materials offers an eco-friendly alternative to traditional packaging materials.
- Honeycomb materials for shipping containers are usually made of kraft paper which is usually characterized by a brownish color. The brown color is not however light reflective and an important proportion of the light that reaches the honeycomb container is absorbed by the latter. Consequently, the temperature of the container and its content slowly increases. The increasing temperature may permanently damage the perishable goods.
- Panels covered with an highly reflective grade aluminum foil on their outer surface were disposed on the honeycomb material to reflect light. These panels were usually made of Kraft paper and helped to bond the aluminum foil to the outer surfaces of the face members perpendicular to the honeycomb core (See for instance U.S. Pat. Nos. 5,000,372, 5,429,264, and 5,492,267).
- With the growing environmental concerns, it is highly desirable to provide containers that are fully and easily recyclable. This is not the case with the honeycomb material covered with aluminum foil since the foil must be removed before recycling the honeycomb material. Moreover, for environmental and economic concerns, it is highly desirable to minimize the quantity of material used to manufacture containers for packaging perishable goods. In the above mentioned patents, the aluminum foil is laminated on an additional Kraft paper bonded perpendicular to the honeycomb material.
