With the requirements of the current global ban plastic limit plastic, plastic or biodegradable become the inevitable trend in the future, common plastic processing methods is still burning cremation, caused a large number of greenhouse gases into the air, and disposable degradable lunch box is buried in the soil degradation, the carbon dioxide directly into the soil organic matter or is absorbed by plants, not into the air,No greenhouse effect.

Today, let's take a look at the disposable biodegradable meal boxes on the market.

1. Pulp molded meal box (plant fiber molded tableware)

Paper pulp molding tableware products in the plastic on the road to have certain advantages, first in terms of raw materials, paper pulp molding disposable lunch box plants such as wheat straw, bagasse fiber as raw material, don't add any PP material, through molded pulp wet compression molding process, waterproof and oil food grade additives is added in the pulp, achieve the effect of hot and cold food.

Plant fiber degradable meal box is the most active type of meal box on the market at present. Take Hainan Province, which took the lead in banning plastic, for example, Hainan Province has completely banned the use, circulation, sales and storage of plastic tableware. Pulp molded tableware is an ideal alternative to plastic.

Sugarcane pulp disposable meal box belongs to total degradation type of meal box, which can be completely degraded into organic matter in 90 days under the condition of industrial composting or home composting, and return to nature.

2. Cornstarch based meal box

Corn starch degradable meal box is made of natural corn starch and plant fiber as the base material, supplemented by biological polyester, polyol and other substances processed.

Corn starch meal box can degrade naturally in soil and natural environment, and the degradation rate can reach 60%-80% according to the composition of the meal box. To a certain extent, it can replace plastic products and reduce white pollution to the environment. It is an ideal alternative to the widely used but controversial "sterilized tableware" in the catering market.

3. PLA biodegradable tableware

PLA degradable meal box usually refers to the product of the combination of PLA composite film and pulp molding products in the pulp molding process, that is, PLA coated products.

PLA composite film is a completely degradable film which is produced and processed by poly (lactic acid) as raw material and can be compounded on paper pulp molding and paper products by heating.

Polylactic acid (PLA) is a new type of biodegradable material, made from renewable plant resources (such as corn) proposed starch raw materials. Starch raw materials by saccharification to get glucose, and then from glucose and a certain strain fermentation to make high purity lactic acid, and then through chemical synthesis method to synthesize poly (lactic acid) with a certain molecular weight.It has good biodegradability. After use, it can be completely degraded by the microorganisms in nature, and eventually produce carbon dioxide and water. It does not pollute the environment, which is very beneficial to the protection of the environment, and is recognized as environmentally friendly material.

In view of the advantages of PLA, by combining the film coating process with the pulp molded products, not only can the use of waterproof and oil-proof agent be saved, but also can better play the role of sealing the pores of the pulp molded products, so that the original cannot prevent alcohol products can prevent alcohol leakage. At the same time, after the air hole is closed, the tableware in the actual use process reduces the permeability of the product, higher insulation performance, insulation time is longer.
