Study on the practicability of non-woven bag instead of plastic bag

 

 

Abstract: so in recent years, there is a new kind of environmental protection material on the market - non-woven cloth to replace plastic bags. Non-woven fabric is a new type of green and environment-friendly material which is easy to operate and carry. It can effectively reduce the environmental pollution caused by the frequent use of plastic bags. In view of the above reasons, our group decided to take non-woven cloth instead of plastic bags as the research direction for in-depth understanding.

 

 

 

 

1. Hazards of plastic bags

For a long time, people everywhere in life, relying on plastic bags, plastic bags also bring great convenience, but we have to face the following problems, plastic product takes hundreds of years to be part of biodegradable plastic garbage in the country that are all over the world, and piled up, the final cause of Marine pollution, killing creatures, finally caused irreparable damage to the environment. According to our investigation, plastic shopping is the main source of white pollution at present.

At this stage mainly through "landfill and incineration" two ways to deal with the difficult to degradation of plastic products, but through the landfill treatment of plastic bags will lead to the destruction of the soil structure, soil losing effectiveness, no use value, become nothing grows, by burning process of plastic will produce many harmful gases, the air pollution. Plastic hazards can be divided into the following categories:

(1) visual pollution: plastic bags are everywhere in life, giving people a messy visual effect and damaging the visual beauty of the environment.

(2) potential harm exists in many aspects: 1) plastic bags containing overheated food will secrete a harmful compound, which will cause adverse effects on our health. 2) damage the soil environment, affecting crop growth and yield. 3) in cities, landfill disposal is a major method of garbage disposal in China. Because plastic products can quickly fill the landfill site, and the ground after the landfill treatment is soft, plastic waste in the presence of many bacteria and viruses and other substances, they are easily infiltrated into the ground, again polluting the groundwater resources, endangering the environment. 4) if the plastic waste is treated by incineration, it will produce many harmful gases and cause secondary pollution to the air.

2 non-woven bags instead of plastic bags

2.1 introduction to non-woven bags

Non-woven bag (non-woven bag) is a new type of green environmental protection products, this kind of bag shape is simple and beautiful, good toughness, strong durability, good air permeability, can be recycled and reused. It can be used for print advertising, washing, and all companies and supermarkets as advertising materials. Consumers can get both shopping and a non-woven bag, and businesses can also achieve publicity through non-woven bags, the best of both sides, so in the market non-woven bags can be more and more popular with the public. Non-woven bag products with non-woven fabric as raw materials, it can be used to replace plastic environmental protection materials, its characteristics are: breathable, moisture-proof, lightweight, flexible, non-flammable, easy to decompose, non-toxic, non-irritating, recyclable. This material is the most suitable material that we choose to replace plastic and does not pollute the environment. It can be decomposed naturally after being placed outdoors for 90 days. When burning, it is non-toxic, odorless and free of any residual substances.

2.2 advantages of non-woven fabrics

(1) air permeability: the polypropylene slice is not soaked, and the moisture content is zero. The 100% fiber has the characteristics of high porosity, good air permeability, easy to keep the fabric dry and easy to clean.

(2) light material: polypropylene resin is the main raw material of production, the proportion is only low, only 60% of cotton, fluffy, feel good.

(3) softness: it is formed by the hot melt bonding of fine fiber and light spot. The finished product is soft and comfortable.

(4) antibacterial and chemical agent: polypropylene is a chemical blunt substances, insect resistance, can be separated in liquid bacteria and insects; Antibacterial, alkali - resistant and finished products will not affect their strength due to corrosion.

(5) antibacterial: this product has the ability to absorb water, not moldy, and can separate bacteria and insect liquid erosion, rather than mold moth.

(6) excellent material performance. The product is made of polypropylene by direct spinning. The strength of the product is better than that of ordinary staple fiber.

(7) in terms of environmental protection, the vast majority of non-woven materials used are polypropylene, while the original material of plastic bags is polyethylene. Although the names of these two substances are similar, their chemical properties are quite different. Polyethylene is extremely stable in molecular structure, so it is difficult to be biodegradable, so plastic bags cannot be decomposed for hundreds of years. However, with polypropylene, the molecular structure is not very strong, it is easy to break, so it can be easily biodegradable. And polypropylene material is avirulent, although be decomposed, its decompose product still avirulent.

2.3 four advantages of non-woven bags

2.3.1 non-woven bag has higher economy

Since the implementation of the plastic limit, plastic bags will gradually withdraw from the market stage and walk towards the road of history. Non-woven bags will replace the core position of plastic bags in the market in the near future. Compared with plastic bags, non-woven bags can be more easily printed on a variety of vivid color patterns. In addition, non-woven bags can be recycled and its consumption rate is far lower than that of plastic bags. Exquisite patterns and advertisements printed on non-woven fabrics will not become expensive because they are only used once, and the cost of non-woven shopping bags will also be reduced.

2.3.2 non-woven bags have better fastness

If traditional plastic bags are used to shopping, in order to save production costs, the material of plastic bags should be as thin as possible and easy to be damaged. A stronger plastic bag would cost more to produce. Due to the appearance of non-woven bags, this kind of problem is solved with the non-woven bags, the toughness is strong, and not easy to wear. Some of them in addition to having a strong nature, but also waterproof coated non-woven bag, its feel is very good, and its beautiful appearance. Although the cost of single non-woven bags is lower than that of plastic bags, the service life of non-woven bags can be equivalent to the service life of hundreds of plastic bags, or even thousands of plastic bags.

2.3.3 non-woven bags have higher advertising effect

A non-woven bag can not only be regarded as a commodity packaging bag, its higher value also lies in other aspects. For example, if the packaging bag has a beautiful shape, which can make consumers love it, it can also be a fashion product, a simple single-shoulder backpack, become a part of the street fashion industry. Considering its firm, waterproof, non-stick nature, consumers will be more willing to choose it. If a company chooses to print a company logo or advertisement on non-woven bags, then it can bring excellent advertising effect.

2.3.4 non-woven bags have higher environmental protection public welfare value

The state has issued restrictions on plastic bags in order to raise citizens' awareness of environmental protection and solve the problem of pollution caused by plastic bags. Non-woven bag recycling, can greatly reduce the use of plastic bags, thus reducing the production of plastic waste. In addition to the increasing awareness of the national environmental protection, more can show the environmental protection image of enterprises, more close to the people.

Non-woven bag implementation plan

3.1 promotion of Shared non-woven sites

The frequent use of plastic bags cannot be separated from shopping in life. Therefore, for shopping people, non-woven bag sharing points should be set around places where non-woven cloth is needed, such as supermarkets, convenience stores and vegetable markets. If personal information is uploaded to the database, it can be used for a certain period of time. A good return record and frequent use can increase users' credit, so as to achieve the effect and expected goal of promoting the nationwide use of non-woven cloth instead of plastic bags, and finally achieve the goal of the nationwide use of non-woven cloth and green.

3.2 solutions for express packaging

Investigation shows that the majority of express packaging for paper or plastic paper system, for this phenomenon we put forward the following solutions: (1) use non-woven bags instead of express paper or plastic packaging, that can reduce the express packaging costs and environmental protection; (2) can be removed on arrival non-woven packaging bags directly recycled; (3) each express company can set up a regional non-woven recycling station, regular recycling cleaning for secondary use.

3.3 solutions for supermarkets

According to our investigation, each supermarket chain will use shopping bags, which are priced from 0.1 to 1.1 yuan. In view of this phenomenon, we have the following solutions: 1. (2) non-woven bags after most of the idle at home, considering this factor, we decided to in the supermarket textile non-woven bag recycling replacement point, non-woven bag recycling replacement coupons; (3) the supermarket often holds some promotional activities, such as yuan for purchase, for this activity we have some improvements, such as one yuan into non-woven bags or coupons; (4) in addition to the coupon can be used in promotional activities, but also can be used in goods shopping checkout above.
