Paper bag improved structure capable of seeing contents

This creation is about an improved structure of a paper bag that can see through the contents, especially if the bag system is made of a single piece of paper. The bag has a transparent window, which is free from windowing, plastic pollution, and promotes food hygiene. Beautified packaging, and has a high-perspective packaging paper bag like transparent plastic.

According to recent years, "SARS", "gut virus", "bird flu" and other viruses have caused public health crisis. Therefore, the food industry pays more attention to "sanitary isolation of food", minimizing the sale of food, reducing the mouth and hand contact of consumers, and promoting the urgent need to improve packaging.

Since the invention of plastics, humans have begun to use plastic bags in large quantities, especially the traditional pastry, bread, meals... more widely used packaging plastic bags made of OPP, PE, PP... However, the disadvantage of plastic bags is that they cause air, food, river and environmental pollution when manufactured and discarded. Plastic bags usually have low heat melting points. For example, PE bags are about 150 ° C, and OPP is about 200 ° C. The temperature of the hot bread that has just been baked is usually as high as 200~300 °C, so it can't be packaged immediately. Therefore, in the busy time of going to and from work, the freshly baked hot bread is packed in plastic bags, and it has been confirmed that plasticizer and chlorine will escape. , doubts about the carcinogenic toxins produced by the human body.

To this end, the current domestic and foreign Chinese and Western snacks, bread and other related food packaging, Most of them have changed to kraft paper bags, white kraft paper bags, oil-proof paper bags, etc. In addition, such opaque paper bags are also commonly used to package medicines, but because general kraft paper and white kraft paper are opaque and occlusive, consumers cannot directly What kind of food or medicine is contained in the outer view bag is its main drawback. Therefore, in order to be both environmentally friendly and maintain the dual effect of see-through, the paper is made of a partially transparent plastic paper bag (commonly known as a window bag) to create a reserved window. However, it still exists in manufacturing. There are a number of missing, because the custom window bag is mainly composed of kraft paper and OPP plastic sheet. The whole bag has about 1/2~1/4 area and needs transparent plastic material, which will cause window sticking. It is not easy to be processed in the industry because it is difficult to process, has a large loss, and has a high cost of sticking a window bag. In addition, the custom-made window bag itself contains two different materials, paper and plastic, which will also cause difficulties in recycling classification. When the paper mill regenerates pulp, it is easy to be rejected due to the mixture of plastic impurities and increased cost.

Based on the shortcomings of the above-mentioned conventional packaging paper bags, the present inventors have designed an improved paper bag structure for seeing the contents in order to improve the disadvantages, mainly including: a bag body, which is made of a single material piece of paper, partially transparent and then The bag body has opposite front and back sides, and the upper end of the bag body has an opening, and the two sides and the bottom side are closed to form an accommodating space, and the bag of the same material is on the bag body. The area is divided to form a shielding portion that cannot package the contents from the outer inner view, and at least one transparent window that can be packaged in the outer inner viewing bag to form a non-toxic paper bag, and has a completely free window in manufacturing and use. It has the advantages of no plastic pollution, promoting food hygiene, and beautifying the sales value of packaging, etc. It provides excellent visual and aesthetic effects, and has a high-perspective packaging paper bag like transparent plastic.
