Abstract

The invention discloses a disposable packaging bag facilitating material taking. The disposable packaging bag facilitating material taking comprises a plastic film and a plastic sheet which is connected with the plastic film. A sealed cavity for padding is formed between the plastic film and the plastic sheet. The plastic sheet is provided with a tearable line for the padding to be extruded out of the sealed cavity. According to the disposable packaging bag facilitating material taking, the plastic sheet is provided with the tearable line, during material taking, the padding is directly extruded out, the padding can be taken out after the tearable line is broken, the material taking speed is high, and it is not need to shear or tear the packaging bag open.

Description

technical field [0001] The invention relates to a packaging bag, in particular to a disposable packaging bag which is convenient for taking out materials. Background technique [0002] Plastic packaging bag is a kind of packaging bag that uses plastic as raw material to produce various supplies in daily life.
