Degradable tableware and paper tableware are popular abroad
How to control and eliminate "white pollution" has become a hot research topic of global environmental protection. For this reason, many countries and regions have issued decrees and regulations several years ago, prohibiting the use of plastic products for packaging food, and began to study alternatives. Japan, the United States, Austria, Italy, as well as scientific and technical personnel of Taiwan Province has researched and developed some of the non-toxic, harmless new packaging materials, which can be completely degraded or can become the renewable resources, and produced the disposable lunch boxes known as the "green packaging" as well as edible-sexual tableware, plant material made tableware and biodegradable tableware with starch as the main ingredient. The alternate matter widely used abroad is paper tableware.
1. Tableware made of plant material
This fast food utensil made from starch and food casing as well as rice and wheat rod, corn stalk, bagasse and other plant material can be completely dissolved after being used, harmless and have non-toxic, non-carcinogenic substances. It can not only rot in the natural environment, and also be used as organic fertilizer and livestock feed consumption, which has no pollution to the environment. The study has not achieved large-scale production.
2. Biodegradable tableware using starch as the main ingredient can be divided into biodegradable cutlery and light bio-degradable tableware two kinds according to the type of degradation agent used.
The biodegradable tableware cooperates by additives in polyethylene and polystyrene material, and mixed with a certain amount of common starch. This tableware can realize three class degradation under natural conditions after being discarded: First, degraded and consumed by the microbes; Second, devoured by lower animals, insects; Third, breakage loss and fragmentation, pulverization, disappear by self-oxidant effect, the degradation process takes about 300 days.
Because the starch of the biodegradable tableware with the main component of starch and additives do not have chemically reaction change with poly hydrocarbons, and therefore the nature of the plastic does not change. The only difference is that with the foam fast food box is that it makes it a shred the starch. Therefore, the foreign countries just use this degradable plastic for packaging agricultural film, garbage and other non-food items. Furthermore, the appearance form of biodegradable tableware is the same with the existing foam lunch boxes, which is likely to mix the false with the genuine, so as to cause difficulties to the management and supervision.
3. Paper tableware
Paper tableware can be divided into paper pulp tableware and paperboard lamination tableware in accordance with different production methods. Molded pulp tableware is made of pure natural plant and pulp fiber as raw material. The appearance has strong plasticity, a wide source of raw materials (straw, wood pulp, bamboo, reed pulp, etc.), and low production costs, its biggest feature is that you can select the appropriate raw materials and processing technology according to the different levels of consumption: high-end tableware for export and luxury hotel can be produced by imported senior wood pulp, the mid-range tableware for general consumers can use ordinary wood pulp, and the extensively used ordinary fast tableware can use reed pulp, white edge paper.
