Abstract
Description
Technical Field
[0001] This invention relates to the field of industrial design-related products, specifically a pollution-free self-standing paper food packaging bag. Background Technology
[0002] Food packaging bags are thin-film containers that come into direct contact with food and are used to hold and protect food. They are mainly used for food preservation and storage, and have good water resistance, moisture resistance and gas barrier properties. They also have good mechanical strength, stable chemical properties, are resistant to oils and greases, are easy to print on, and can be heat-sealed.
[0003] However, most existing industrially designed food packaging bags are made of plastic, which serve no purpose after being torn off, easily leading to a large waste of resources and garbage. They cannot ensure that the food inside remains clean during the removal process, and microplastic residues may remain on the food surface after contact with the food during storage, which can easily harm human health. Furthermore, food packaging bags are non-biodegradable after use, damaging the environment and thus having defects.
[0004] In summary, the problems with existing technologies are that plastic food packaging bags cannot guarantee food cleanliness, pose risks to human health, and are highly polluting and destructive to the environment. Therefore, it is essential to design a 100% biodegradable, pollution-free, and self-standing paper food packaging bag that can be torn off and used as a mittens for handling food. Summary of the Invention
[0005] The purpose of this invention is to address the defects and shortcomings of existing plastic food packaging bags by providing a 100% biodegradable, pollution-free, and self-standing paper food packaging bag that can be torn off as a glove for picking up food.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a pollution-free self-standing paper food packaging bag with industrial design, comprising a packaging bag, characterized in that an easy-tear dotted line is provided in the upper quarter area of the packaging bag, the easy-tear dotted line is connected by a horizontal dotted line to the left and a diagonal dotted line to the right, the ends of the two diagonal dotted lines each have a notch, and the coverage area of the two diagonal dotted lines is covered by a piece of paper.
[0007] Preferably, the pollution-free self-standing paper food packaging bag is made of kraft paper material, which makes it easier to reduce costs, protect the environment, and benefit human health.
[0008] Preferably, the upper part, left side and right side of the packaging bag are bonded together on both sides.
[0009] Preferably, the easy-tear label dashed line is an axisymmetric line, and the easy-tear label dashed line is connected at both ends of the horizontal dashed line in the center to the diagonal dashed line to the left and the diagonal dashed line to the right.
[0010] Preferably, the diagonal dotted lines of the easy-tear mark, both the left-facing and right-facing diagonal dotted lines, are higher towards the center and lower towards the edge.
[0011] Preferably, the notch is a right-angled triangle with the outermost side being the right-angled side, and the notch can help to tear off the area of the finger sleeve.
[0012] Preferably, the paper pieces are attached tightly to the packaging bag with their outer edges as the sides.
[0013] Preferably, the dotted part of the easy-tear label can be used as a finger sleeve after being torn off.
[0014] Preferably, the paper can be torn off so that the finger cot can directly contact the food inside.
[0015] The beneficial effects of this invention are as follows: the packaging bag can significantly reduce the risk of food being contaminated before and during use, and can be used as gloves after the packaging is torn open, which can make great use of waste and reduce a large amount of water used to wash food and hands. Moreover, the packaging bag is made of 100% biodegradable materials, which can effectively protect the environment and public health and safety. It has the advantages of simple structure, convenient and quick operation, and hygiene and environmental protection, and is worthy of widespread promotion.
