[Technical Field] Method: η ::: Quality container and how to make the wooden container: a kind of wood-binder blank material is converted into a higher precision to [Background of the invention] for use in food or Fresh Rong Baolong is the main product. Paper containers were originally water, and a layer of plastic PE was coated on the surface to completely lose the gas. Because it is mainly paper, plastic or has breathable properties, but usually to prevent film or chemical wax, the original production of transparent plastic j is expensive, and it is usually not suitable for low-cost fresh packaging. Since it is completely impermeable to air, it is easy to get stuffy when it leaves the freezer. However, in order to reduce the cost of packaging fresh meat, we must use a polystyrene container to hold it, and then add a layer of transparent film. The Lilong container is completely impermeable. Although it looks flammable, it feels hygienic, dry and stale inside. Whether it is plastic, it decomposes and disappears after being discarded. It is nine thousand tons in a landfill, even if it is decomposed. In this way, excessive dragon waste has become an environmental protection issue and application. At present, the fresh packaging method is clean, but it is actually very easy to make food glue or polystyrene containers.疋 It has been buried for decades and will not be used for self-consumption. Plastic or Poly are actively trying to solve or reduce the use of as much as possible.
