Proper, high-quality liners are integral for high R value insulated packaging. A high R-value is used to describe the performance of these products and their insulating capabilities. A high R score means a material demonstrates superior thermal resistance. This property is described precisely with the measurement (m²·K)/W or squared meters-Kelvin per Watt. As the thickness of a material increases, so does the R-value.
Conversely, as a material increases in thermal conductivity, the R-value decreases. Therefore, shipping products intended to protect perishable goods should have a high R-value. In other words, the material needs to efficiently prevent the transfer of external heat energy to the inside contents of a transported container.
Insu R-Liner is a multi-layered, laminated poly bubble material filled with insulating gas, a metallic reflective outer layer which provides very high thermal resistance (R value).
Heat-resistant packaging requires dependable, insulated lining. Heat is the number one environmental risk factor for transporting sensitive goods. As such, insulating materials and shipping methods are needed to prevent any damage from happening, even from a couple of hours of heat exposure. If shipping products equipped with high R-value liners are not correctly used, medical supplies like vaccines, for instance, can be rendered ineffective because of temperature changes. Similarly, biological materials transported for medical establishments, like blood samples and donated blood, must be handled with much care regarding maintaining correct temperature levels. Otherwise, these sensitive materials can be rendered unusable or even toxic for human use. Perishable food products, like poultry, vegetables, and dairy products, must all be kept cold to avoid ripening and bacterial contamination. Even cut flowers must be kept cool properly using insulated packaging and liners to maintain their appearance and prevent wilting. It is important to note, though, that the optimal temperatures for all of these materials vary and must be transported strategically and separately if need be. Some tropical fruits, for instance, are susceptible to freezer burn at a temperature that would not be cold enough for other foods.
High R-value products can be made into more sustainable packaging solutions for companies in Southwestern Ontario and the GTA. This is made possible through the usage of materials from sustainable sources, designing packaging to optimize and avoid excess material, and by enabling post-consumer recycling and composting, depending on the material. There are plastic liners and packing foams on the market, for example, made from biodegradable substances like starch-based polylactic acid. Another clever lining insulation alternative is natural sheep’s wool, which is fantastic at absorbing excess air moisture. Along this vein, TempGuard liners, which are made entirely of both heavy-duty papers and paper fibres, are completely recyclable and biodegradable.
By following the illustration, you can easily assemble the insulated box liners in Canada. Fold Panel A along the backside and bottom of the box. Then, fold Panel B along the front and sides of your box. The edge will be on the top of Panel A on the bottom.
Make sure the panels press securely along the edges of the box and that there are no gaps. Now, place the items inside the box. Finally, fold Panel A’s top over the box
Our AB box liner doesn’t take up much space in your warehouse and comes as two custom die-cut pieces to transform the ordinary boxes into an shipping insulated boxes for frozen food. The FDA has approved the gusseted liner for accidental contact of food, and it resists leaks well.
