Description

Method of making zero or less waste from the bag

The invention relates to a method for manufacturing a bag, in particular to a method for manufacturing a bag with zero or less waste, which can be used in a flat bag with a receiving space after performing the first sealing and cutting operation. Forming a first bag and a second bag semi-finished product, the first bag and the second bag semi-finished product are completely complementary in configuration, and all of them have a handle, which fully meets the needs of the user, and the production process is completely non-produced. Waste, or only a small amount of waste, can completely or substantially eliminate the resources needed to recycle and reuse such waste, and thus achieve the goal of energy conservation and environmental protection from the root.

In recent years, with the increasing awareness of environmental protection, more and more countries have proposed a "plastic limit order." In India, for example, the High Court has ordered the government of Delhi to completely ban the use of plastic bags in markets, shops, hotels and hospitals. However, municipal experts believe that plastic bags are an indispensable item for the masses and cannot be used for a while. In addition, according to the Central News Agency, the Delhi government established the "Plastic Bag Method" as early as 2000 to formulate the thickness of plastic bags for various purposes. It is also forbidden to throw plastic bags into ponds and ditches. In the same year, the Indian Parliament passed the "anti-plastic bag law" and was first implemented in northern India. It is forbidden to produce, use, store and sell plastic bags. However, to this day, plastics are still visible in most parts of India, including northern India. The use of bags is rampant, and piles of plastic bags of garbage can be seen everywhere on the streets. When heavy rains block the sewers, causing flooding, becoming a hotbed of malaria mosquitoes, causing various deadly diseases, and local treatment of plastic waste is often caused by burning. Air pollution. The non-government environmental organization "Tapas" said that Germany, Singapore, and even Bangladesh, a poor neighboring country in Bangladesh, have achieved good results in implementing banned plastic bags, but India has not been able to improve the abuse of plastic bags. In fact, it has so far Plastic bags are still widely used in the world, including packaging of pharmaceuticals, personal care products and food. At present, many countries and cities around the world have implemented banned plastic bags. For example, San Francisco has announced that it prohibits the use of plastic bags in large supermarkets. The bill to promote environmentally friendly recycling; London, England also enforced law enforcement stores for shopping plastic bags, and hope to encourage businesses and customers to use environmentally friendly bags to reduce the use of about 13 billion plastic bags per year.

In contrast, China's Environmental Protection Agency, starting in the Republic of China in 1992, stipulates that department stores, shopping centers, mass merchandisers, supermarkets, chain convenience stores, chain fast food restaurants and storefront catering businesses are prohibited from providing plastic bags free of charge. Consumers must pay for them. The purchaser of 0.06 mm thick plastic bags, after the implementation of the policy, in addition to the store catering industry only reduced the use of plastic bags by 20%, other businesses have successfully reduced the use of 70% to 80%. According to this, the Waste Management Office of the Environmental Protection Department said that in view of the Taiwanese people's habit of eating soup and water, the plastic bags that are taken out are easily stained and greasy by the soup, and cannot be reused. If the use of thick plastic bags is continued, Although the number of discarded plastic bags can be reduced, the total weight of the plastic bags will gradually increase. Therefore, since the Republic of China in 1995, plastic bags have been opened again. In order to improve this problem, the EPD has further promoted the recycling of plastic bags. For example, in the past, about 20 billion plastic bags were used in Taiwan each year. The average person uses 2.5 per person per day. After promoting the ban of some businesses, the annual reduction is about With the use of 2 billion plastic bags and the recycling of plastic bags, 3.5 billion plastic bags have been recovered, equivalent to 12,257 metric tons of plastic waste. These recycled plastic bags, After hot-melting, drawing and granulating into recycled plastic materials, it can be made into plastic products such as toolboxes, flower pots, pots, garbage bags and other non-prepared foods.

However, whether it is restricted or recycled, the environmental problems caused by plastic bags have always existed. After all, plastic bags made of petrochemical products will not only cause pollution during the manufacturing process, but also will not degenerate naturally. The problem of pollution will not only block the ditch, but also cause the fish to swallow and die. If the temperature is insufficient and the incineration is incomplete during incineration, it will cause Dioxin, which has a great impact on human health. However, if the government excessively restricts the use of plastic bags, the use of paper bags by businesses and people does not mean environmental protection. Because paper products consume more energy than plastics when they are manufactured, they also cause environmental burdens. Moreover, for paper cutting. Trees will cause ecological catastrophe. "In order to facilitate convenience and hygiene, it is impossible for human beings to completely ban plastic bags and paper bags, but it can be "saving". For example, the dry plastic bags for general items and the wet plastic bags for food can be separated. Reuse; fixed purchase of catering students, office workers, develop the habit of self-contained containers to hold food, reduce the use of plastic bags to a minimum, use one less per day, use less than three hundred a year Fifteen plastic bags, in short, "It is important to sort and recycle, it can be better!" However, in fact, the inability to eliminate the use of plastic bags has always been an important environmental issue facing all countries in the world.

According to the instructions of all countries in the world when making such plastic bags, the main steps are as follows: (1) Please refer to Figure 1 to first set up a roll of bag 10 to a production line.
