What does plastic garbage bag mean by 2 silk and 3 silk

2 or 3 wires represent that the thickness of plastic film of garbage bag is 0.02 mm or 0.03 mm

1 mm is divided into 100 parts, one of which is commonly known as 1 wire, that is, 0.01 mm. Because the general plastic film is too thin, its thickness is expressed by wire. The greater the wire value, the thicker the film, and the better the strength

extended data:

first, according to the design concept of environmental protection, choose garbage bags:

first, buy “can hold”, because the general garbage bags can only hold 2 /3 of the capacity. You can’t close the mouth again, which is not conducive to garbage cleaning, Choose “The automatic closing garbage bag can make full use of the capacity space of the garbage bag, and can contain more garbage, so as to use less plastic bags.

Second, the garbage bag can be divided into two designs, one is flat bottom and the other is octagonal bottom. The garbage bag with flat bottom design has large capacity. The octagonal bottom bears more force and stronger gravity.

the third mark uses high-strength PE pure new material, which is better than using only secondary recycling The receiving bag body is more extensible, more flexible and durable, and is not easy to puncture. Precautions

Fourth, choose a garbage bag that is convenient for closing, which is conducive to the disposal of garbage. If the garbage bag is easy to break and leak, it is not easy to close, and the environmental protection workers scatter all over the ground when dealing with the garbage, which is not conducive to environmental protection

2 or 3 wires represent that the thickness of the plastic film of the garbage bag is 0.02 mm or 0.03 mm

1 silk = 10 microns = 0.01mm

the unit for measuring the thickness of plastic bags is generally expressed in silk and microns. The formula conversion is: 1mm (mm) = 10 silk meters (DMM) = 100 hum (CMM, also known as silk) = 1000 microns (umm). The state stipulates that the thickness of plastic bags in supermarkets shall not be less than 0.025 mm, that is, 0.25 silk meters and 2.5 silk meters (also known as 2.5 silk). Silk’s English word is silk

like a transparent vest bag, the thickness of one side of the shopping bag is generally 2 silk, 3 silk, or even less. Clothing bags are generally as thin as 5 silk and as thick as 12 silk. The thickest one is hard to say. At present, it has 16 wires. In short, the larger the bag, the more things to pack, and the heavier it is, the thicker it needs to be. Small food packaging bags are generally 8 wires or more, and the materials used are mostly made of polyethylene film. The film is non-toxic, so it can contain food

extended data

there is a film made of polyvinyl chloride. Polyvinyl chloride itself is not toxic. The additives added according to its purpose have certain toxicity and cannot contain food. How to distinguish between polyethylene and polyvinyl chloride

polyethylene film (non-toxic):

the film is milky white and translucent. It feels smooth. It seems to be coated with wax layer. It shakes hard and has a crisp sound. It is flammable in case of fire. The flame is yellow. There is mucus dripping during combustion and the smell of candle combustion

PVC film (generally toxic):

if no pigment is added, it is transparent. It feels sticky on the surface, shakes with force, and has a low voice. It is not easy to burn in case of fire. It extinguishes when it is away from the flame, and the flame is green

knowing these is easy to distinguish in life and avoid endangering health

Plastic packaging bags can be divided into OPP, PP, CPP, PE, PVA, EVA, composite bags, coextrusion bags, etc

OPP plastic bag:

good transparency and strong hardness, but the edge seal is easy to tear

phthalates may harm the reproductive organs of male infants, affect the development of children’s sexual characteristics, and even cause cancer of the reproductive system

phenol methane is also a chemical commonly used in plastic products, which may lead to breast cancer in women. p>

substances such as phthalic acid and phenol methane are collectively referred to as environmental endocrine disruptors, which play a hormone like role and affect the human endocrine system

what is the thickness of the garbage bag?
