The vest-type garbage bag is named after its appearance resembles a vest. Those two "shoulder straps" are portable and easy to carry. Due to regional differences, vest-type garbage bags also have different names, some are called vest-type garbage bags, some are called portable garbage bags, and some will become garbage bags with ears.
In the production process, all the steps of vest garbage bag are the same as those of flat garbage bag. The vest-type garbage bag is one step more than the flat garbage bag, that is, cutting "ears" directly on the flat garbage bag. So in fact, the production cost of vest garbage bag is higher than that of flat garbage bag.
There is no obvious difference between vest-type garbage bags and other garbage bags except for appearance in production and use. With the improvement of production equipment, vest-type garbage bag products have been upgraded many times, and many styles and different packaging have appeared, but the shape has not changed. For example, there are broken vest-type garbage bags, unbroken vest-type garbage bags, detachable vest-type garbage bags and so on.

Harm of garbage bag
Most of the plastic bags people use for daily shopping are made of petroleum. Because of the huge usage, the waste of resources and environmental pollution are amazing. It takes about 200 years for plastic bags to rot when buried underground, and it seriously pollutes the soil; If incineration is used, it will produce harmful smoke and toxic gas, which will pollute the environment for a long time.
In China, 654.38 billion plastic bags are used to buy food every day, and the consumption of other plastic bags exceeds 2 billion every day. Every year, 2.3 billion plastic bags are discarded in Beijing, resulting in 65.438+0.4 million tons of waste plastic packaging waste, accounting for 3% of the whole domestic waste. Shanghai produces 6.5438+0.9 million tons of waste plastic packaging waste every year, accounting for 7% of the total domestic waste. Tianjin's annual waste plastic packaging waste also exceeds 6,543,800 tons. The plastic bags presented by shopping malls are mainly non-degradable, which will seriously harm the environment if used as garbage bags.
Selection criteria of garbage bags
First of all, according to the design concept of environmental protection, choose garbage bags:
The first thing to buy is "can hold", because ordinary garbage bags can only hold 2/3 of the capacity. Reloading cannot be closed, which is not conducive to garbage cleaning. Choosing "automatically close garbage bags" can make full use of the capacity space of garbage bags and can hold more garbage, thus using less plastic bags.
Secondly, garbage bags have 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 at several points.
The third label is made of high-strength PE pure new material, which is more elastic, flexible and durable than the bag with only secondary recycled materials. Matters needing attention
Fourth, choose garbage bags that are easy to seal, which is beneficial to garbage disposal. If the garbage bag is easy to leak and not easy to close, environmental protection workers will scatter all over the floor when dealing with garbage, which is not conducive to environmental protection.
How to use vest garbage bag
There is little difference between the use of vest garbage bag and flat garbage bag, and the steps are basically the same.
After getting the new vest garbage bag, twist the opening with your fingers and hold it in one hand. At that time, shake it up and down two or three times to let the air in, and the vest garbage bag will open itself.
Then, put it into the trash can, and pay attention to the plane contact between the bottom of the vest-type garbage bag and the bottom of the trash can. The excess part at the upper end of the garbage bag is turned over along the mouth of the trash can.
If you are worried that the vest-type garbage bag will "slide down" in the process of "loading garbage", you can tighten it and tie a knot at the flip end (note that the knot should be a slipknot).
When the garbage is full, the vest garbage bag is more convenient and sanitary than the flat garbage bag. Vest-type garbage bags can be removed by "pulling and lifting", while flat-mouth garbage bags need to be "closed", clenched (some people will tie a knot) and then twisted open.
