【 Abstract 】 :
With the approach of the new "plastic limit order" to prohibit the use of plastic products, a variety of degradable plastic bags known as "no special treatment can automatically disappear" have brought severe shocks to the capital market, won the market's attention and continue to heat up, becoming the industry's "new favorite." Degradable disposable tableware, garbage bags, degradable plastic bags and other products are rapidly becoming popular, many products hit the "environmental protection", "degradable" flag, appearance level is also in line with the public aesthetic, although the price is slightly higher than non-degradable disposable products, but still by a lot of attention to environmental protection consumers. So what is the production principle of unbreakable plastic bags? Today, Goolien Packaging, a professional flexible packaging manufacturer, will give you a popular science.
Degradable plastic bags, the implication is that they can be degraded, but the degradable packaging bags are divided into "degradable" and "fully degraded" two kinds. Degradable plastic bags refer to plastic bags that add a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizers, biological degraders, etc.) in the production process to reduce its stability, and then are more easily degraded in the natural environment. Completely reduced plastic bag means that the plastic bag is completely degraded into water and carbon dioxide. The main source of this fully degradable material is processed from corn, cassava, etc. into lactic acid, that is PLA.
Polylactic acid (PLA) is a new biosubstrate and renewable biodegradable material, starch raw material through saccharification to obtain glucose, and then from the glucose and a certain strain of fermentation to produce high purity lactic acid, and then through chemical synthesis of a certain molecular weight of polylactic acid. It has good biodegradability, after use, it can be completely degraded by microorganisms in nature under specific conditions, and eventually generate carbon dioxide and water, which does not pollute the environment, which is very beneficial to the protection of the environment, and is an environmentally friendly material for workers.
So how to identify biodegradable plastic bags? The method of "1 look, 2 touch and 3 smell" can be used as the primary basis for identification.
1. At first , it refers to the QS logo on degradable plastic bags; The second is to see whether the surface of the product is smooth and whether there are black spot impurities.
2. Touch, refers to the strength of a degradable plastic bag, the use of recycled waste or industrial grade products, the strength is generally very poor, gently tear will split, on the contrary, the use of regular degradable materials strength is larger, not easy to tear.
3. Smell, refers to the smell of degradable plastic bags have odor, after qualified inspection of degradable products are odor free.
