Biodegradable plastic shopping bags refer to bag products made of biodegradable resin as the main raw material, with a carrying structure, and are used to hold and carry goods in sales, service and other places. Biodegradable plastic shopping bags can be divided into biodegradable plastic shopping bags for direct food contact and biodegradable plastic shopping bags for non-food contact according to whether they are in contact with food.

At present, the common biodegradable plastics mainly include polylactic acid (PLA), polycaprolactone (PCL), butylene glycol dilate (PBS), polyhydroxybutyrate (PHB) and polycarbonate lactone (PPC). , polybutylene terephthalate-adipate (PBAT), etc.

Current status of degradable plastic shopping bags

The national plastic pollution control policy stipulates that non-degradable plastic shopping bags belong to the list of plastic products prohibited by the country, and degradable plastic shopping bags are one of its substitute products. However, through this sampling, it was found that the current status of the use of degradable plastic shopping bags is not optimistic. The basic status is as follows:

1. The price cost is high. The price of degradable plastic shopping bags is mostly 0.6-1.2 yuan per piece, which is double the price compared with ordinary plastic shopping bags. Mainly due to the high cost of degradable plastic raw materials, the current price of PLA raw materials is 15,000-30,000 yuan/ton, the price of PBAT raw materials is 14,000-25,000 yuan/ton, and the price of PE raw materials is only 0.8-10,000 yuan /Ton.

2. The performance of consumers is poor. The material of degradable plastic shopping bags is too soft, and there are problems such as easy breakage of the handle and poor performance of the bag body.

3. Most of the production enterprises are in the initial stage of transformation. Many plastic shopping bag manufacturers have transitioned to biodegradable plastic production. However, because the material is different from traditional plastics, the company needs to adjust the processing technology and production formula, not only to meet the degradable performance, but also to meet the performance requirements and hygiene requirements stipulated in product standards (plastic products for food contact). The new products developed do not meet the standard requirements.
