The thickness of a qualified biotech degradable plastic bag should not be less than0.025mm, The biodegradable plastic bags that cause a kind of white garbage flying in the sky are mainly aimed at these thin and thick0.025mmof thin biodegradable plastic bags. Interference regularity of water-repellent performance of biodegradable particulate matter, obtainedSPIThe modified processing technology standards for biodegradable materials are:SPIRatio of mass to volume of tetrahydrofuran1:3, and the use of orthogonal and compositional experimental designs improves theSPIStandard for Modification of Biodegradable Materials; Prepared under StandardSPIThe tensile strength of the biodegradable material is8.61MPa, the tensile strength is196.78%, the water absorption is31.6%Biodegradable plastic bags are easy to produce after non-biodegradable material waste”plastic trash”, the solution of this insoluble material has created great technological difficulties and also promoted the development trend of biodegradable materials. Biodegradable materials are accompanied by the improvement of people’s concept of protecting the ecological environment, the continuous reduction of coal resources, the replacement of traditional crude oil-based polymers by biodegradable polymers has already become a development trend in the future. The key to white garbage is the environmental pollution of visual information content caused by environmental elements and the potential risk of harming social development2Each level adversely affects utility. Scattered in domestic cities, the plastic waste thrown away by everyone has caused huge damage to the city appearance and the development trend of garden landscapes. Moreover, because the plastic waste enters the ecological environment in our country and cannot be dissolved, it is difficult to analyze the current situation.In order to better protect the ecological environment and save energy, biodegradable plastics should have a statement of the natural environment that has been used several times, as well as a statement of warning and safety, and should be kept away from babies to avoid breathing and other injuries. Direct contact with food should also be marked with the word food. In short, such warning signs and indicated standards cannot be ignored.The packaging bag needs to have the established name, standard number, specification model, load and other signs. The label should be applied in a striking shade, not fading or falling off, and can be printed or sprayed, but it must not compromise the performance of the biodegradable plastic bag. The labeling should be on the obvious part of the biodegradable plastic bag, and should be marked with the name of the manufacturer, the date of manufacture, inspection and quarantine certificate, and the storage period should not exceed one year.
