As we all know,the state's opinions on the development of degradable plastic bags are very clear.On July 10 last year,the nine departments jointly issued the notice on Solidly Promoting the treatment of plastic pollution,proposing a series of measures such as strengthening the suoervision and management of commodity retail places,take out services,various exhibition activites,etc.,and stopping the use of non degradable plastic bags to promote the treatment of plastic pollution.
Many people have also found that when they go to the supermarket for shopping,the price of plastic bags has doubled.Plastic bags that originally cost 0.3 yuan may now need 0.6 yuan to set a higher price.Therefore,many users ask whether the development of degradable plastic bags with such high prices will encounter resistance,whether it is necessary to buy the corresponding degradable film blowing machines and bag making machines,and whether it is the same to choose ordinary film blowing machines and bag making machines?Not only that,some people even questioned the so-called degradability.
Judging from a series of national measures,it is certain that degradability is definitely needed!At present,the relatively high cost of degradable raw materials also objectively exists,because everyone knows that what needs to be paid first is because in the past,people didn't care,force and demand,which led to the current plastic pollution.If we want to correct this problem,we must pay more.
From the perspective of the industry,take the most common biodegradable PLA as an example,the unit price of raw materials is 25000-30000 yuan/ton,while the price of raw materials for one ton of polyethylene is generally below 10000 yuan. Correspondingly,in the process of film blowing abd bag making,due to different raw materials,manufacturers pay more attention to the characteristics of degradable raw materials and design more accurate process data.It is worth mentioning that many people boast that one equipment can complete blowing of multiple or various raw materials,which is unscientific and lax.As simple as die head,tension,mesh size and so on,it needs to be tailored to achieve the best effect with more accurate and suitable data.
At present,the cost of raw materials is the primary factory for the high cost of degradable plastic bags.With the development of science and technology and the continuous efforts of scientific and technological personnel,all of these will inevitably be the same as other indudtries,and new technologies and materials will continue to emerge.At present,we should conform to social development and respond to the call of green environmental protection.If everyone moves in the same direction,the cost factor will no longer exist!
On the other hand,whether it is degraded or not,recycling is a better solution.
