Water-absorbing degradable plastic bag

Abstract

The invention provides a water-absorbing degradable plastic bag. The bottom of the plastic bag comprises a surface wrapping layer, a water-absorbing core layer and a plastic bag body from inside to outside, wherein four edges of the surface wrapping layer are bonded with the plastic bag body by means of heating. As a highly water-absorbing resin layer is added to the bottom of an existing plastic bag and fixed to the bottom of the plastic bag through the surface wrapping layer, waste water in plastic flows down along the wall of the bag under the action of gravity, and is accumulated at the bottom of the bag and absorbed by the water-absorbing core layer, so that the whole plastic bag is kept dry, and food waste contained in the plastic bag is not easy to deteriorate and stink. Besides, by the aid of the added water-absorbing core layer and the surface wrapping layer, the bottom of the plastic bag, mainly used for bearing, is firmer and not easy to be damaged. The plastic bag body made of polyethylene modified materials can be naturally degraded, so that white pollution is reduced.

Description

technical field [0001] The invention relates to a plastic bag for daily use. Background technique [0002] At present, the garbage plastic bags used by many households to pack food waste often leak, especially liquid food waste. It is often some unpleasant soup dripping on the floor of the elevator room and corridor, which affects the cleanliness and beauty of the environment. [0003] Many consumers are currently using inexpensive single-use plastic trash bags that often simply hold liquid waste, are often designed not to hold liquids, lack adequate closure and airtight construction, and are very thin due to cost considerations , It is easy to break during use, causing liquid waste to leak more easily and destroying the living environment. And most plastic bags are not biodegradable, causing serious white pollution. [0004] In addition, the plastic bags used for packing boxes in the hotel are not tightly sealed, and the vegetable soup in the lunch box is easy to leak, a...

It is often some unpleasant soup dripping on the floor of the elevator room and corridor, which affects the cleanliness and beauty of the environment

[0003] Many consumers are currently using inexpensive single-use plastic trash bags that often simply hold liquid waste, are often designed not to hold liquids, lack adequate closure and airtight construction, and are very thin due to cost considerations , easy to break during use, causing liquid waste to leak more easily and destroying the living environment

And most plastic bags are not biodegradable, causing serious white pollution

[0004] In addition, the plastic bag used for packing boxes in the hotel is not tightly sealed, and the vegetable soup in the lunch box is easy to leak, and it is easy to cause secondary pollution when it is taken out for use.
