An environment-friendly degradable plastic food packaging bag

Abstract

The invention belongs to the technical field of food packaging, and specifically relates to an environment-friendly degradable plastic food packaging bag, which includes a bag body made of degradable plastic, with an opening on the upper end of the bag body; Two strips are respectively symmetrically bonded on the front and rear sides of the body; the thickness of the strips is greater than the wall thickness of the bag body, the upper end surface of the strips is flush with the upper end surface of the bag body, and the height of the strips is It is two-thirds of the height of the bag, and there are two pre-folds equidistant from top to bottom on the strip near the front side of the bag; the present invention bends the strips on both sides along the pre-folds , so as to effectively realize the sealing of the tea bag body, reduce the chance of tea leaves being yellowed and dampened in contact with moisture in the air and affect the taste, and the height of the strip is two-thirds of the height of the bag body, and the remaining The tea leaves are located under the pre-creases of the strips, and the strips will not squeeze the tea leaves and cause the tea leaves to break, ensuring the quality of the tea leaves.

Problems solved by technology

[0003] The tea culture in China is extensive and profound. Drinking tea has been a hobby of many Chinese people since ancient times. There are various tea packaging styles. One of the tea packaging is to put multiple sealed small bags of the same specification into a metal box for packaging.
