Wheat starch and its straw fiber will become new materials for fast food packaging

Over the years, fast food has used a variety of different materials for packaging, and for one reason or another, each material has proven problematic. However, according to a recent study submitted at the American Chemical Society Conference, researchers finally discovered a better, cheaper, more environmentally friendly snack packaging method.
According to foreign reports, most snacks were initially packaged in polystyrene clam shells. This material is lightweight, easy to make and maintains the temperature of the food. Unfortunately, polystyrene cannot be degraded. It also contains ozone-depleting chlorofluorocarbons. Taking into account the fact that these materials have caused environmental pollution, the fast food industry has switched to paperboard, but cardboard also has drawbacks. The United States Department of Agriculture’s Jeffrey Nobles said: “Boards are more expensive, heavier, and the production is more complicated. It does not keep warm.”
Therefore, Nobbesse and his colleagues in the Ministry of Agriculture began to search for a better material. They concluded that packaging with wheat—that is, fiber using wheat straw and starch in wheat grains—has good prospects. The wheat box can be completely degraded. Nobels emphasized: "If people have a heap of fertilizer in the backyard, they can throw these boxes in the fertilizer heap."
In the past, people used potato starch to make starch-based packaging, but wheat starch is much cheaper than potato starch. In addition, the packaging box made of wheat starch is longer than the commonly used cardboard box or the box made of potato starch. (China Packaging News)

Interlocking Decking

GD Decking is an innovative patent-pending design with clipping style for cover and base, which ensures that they can be installed quickly and easily without cutting. There's eye-catching lines on the deck board, making the decking surface slip resistant and improving overall safety. Besides, the concept for movable deck board cover provides the customers with more options for the decking appearance. The grooves of inbuild deck board base can be also used as drainage channels that makes the decking perform better in drainage.
