Description

Improved structure of paper bag with see-through contents

technical field

The utility model relates to an improved structure of a paper bag whose contents can be seen through, in particular, the bag body is made of a single material of paper, and the bag body has a transparent window, which avoids pasting the window during manufacture, has no plastic pollution, and can promote food consumption. Hygienic and beautifying packaging, but also has a packaging paper bag with high perspective function like transparent plastic.

Background technique

By the way, due to the spread of viruses such as "SARS", "enterovirus", and "bird flu" in recent years, the crisis of public health has been caused. Therefore, the food industry pays more attention to "hygienic isolation food" and minimizes naked food sales to reduce consumers' mouth foam and hand contact, and promotes the urgent need for improved packaging.

Since the invention of plastic, humans have started to use plastic bags in large quantities, especially for traditional pastry, bread, and meals... more packaging plastic bags made of OPP, PE, PP and other materials are used as packaging. However, the disadvantage of plastic bags is that when they are manufactured, used and discarded, they will cause air, food, river and environmental pollution, and plastic bags usually have a low thermal melting point, for example, PE bags are about 150 degrees Celsius, OPP bags are about 200 degrees Celsius, and The temperature of freshly baked hot bread is usually as high as 200-300°C and cannot be packaged immediately. Therefore, it has been confirmed that plasticizers and chlorine gas will escape when packaging freshly baked hot bread in plastic bags during the busy hours of commuting and work. Concerns about the production of carcinogenic toxins in the human body.

For this reason, most of the packaging of domestic and foreign Chinese and Western snacks, bread and other related foods have been replaced by kraft paper bags, white kraft paper bags, oil-proof paper bags, etc. 1. The white kraft paper is opaque and has blocking properties. Consumers cannot directly see what kind of food or medicine is contained in the bag from the outside and inside, which is its main shortcoming. Therefore, more advanced designs use paper bags partially pasted with transparent plastic (commonly known as window bags) to produce the function of reserving see-through windows in order to be environmentally friendly and at the same time maintain the double effect of seeing through. There are a number of missing items, because the traditional window sticker bag is mainly made of two different materials, kraft paper and OPP plastic sheet. About 1/2 to 1/4 of the area of the whole bag needs to be made of transparent plastic material, which will cause window stickers. The three shortcomings of difficult processing, high loss, and high cost of window bags have not yet been popularized in the industry. In addition, the traditional window bag itself consists of two different materials, paper and plastic, which will also cause difficulties in recycling and sorting. Paper mills tend to be rejected due to the mixing of plastic impurities and higher costs when recycling pulp.
