For a long time, kraft paper packaging has been favored by various industries, and the catering industry is no exception. Many businesses in the catering industry use kraft paper as food packaging. What are the benefits of using kraft paper as the material for food paper bags?
First of all, kraft paper bags are non-toxic, tasteless and pollution-free, and the use of kraft paper packaging is in line with the environmental protection concept advocated by the country. Because kraft paper has the characteristics of high strength and high environmental protection, it is now one of the most popular packaging materials in the world. Kraft paper bags made of kraft paper are getting more and more attention, and they can be seen everywhere in supermarkets, shopping malls, clothing stores and other places. Therefore, the catering industry catches up with the trend of kraft paper bag packaging and is more easily accepted by consumers. And the kraft paper bag is suitable for printing different patterns, which is more interesting.
Furthermore, kraft paper is based on wood pulp paper, and the colors are divided into white kraft paper and yellow kraft paper. A film of PP material can be used on the paper to prevent oil and water, and the strength of the bag can be made from one to six layers according to customer requirements. As we all know, paper is a recyclable resource. The raw materials for papermaking are mainly plant fibers, which are renewable resources. But the plastic bags we use are made of polyethylene. The raw material of polyethylene is petroleum, which is a non-renewable resource. In comparison between the two, food paper bags made of kraft paper are more degradable and recyclable, which can be more favored by merchants.
Speaking of the first kraft paper bag for shopping, it was born in 1908 in St. Paul, Minnesota, USA. In order to promote sales growth, a local grocery store owner, Walter Duvina, began to look for new ways to make consumers buy more things at one time. He believes that it should be a prefabricated bag that is inexpensive and easy to use, and can bear at least 75 pounds. After repeated experiments, he locked the raw material of this bag on kraft paper. Because kraft paper is pulped from conifers with long wood fibers, it is treated with mild chemicals during the cooking process, so that the original strength of the wood fibers is less damaged. Therefore, the final paper produced has tight connections between fibers, and the paper is tough and can withstand greater tension and pressure without breaking.
With the global prevalence of anti-plastic wind, environmentalists have turned their attention to kraft paper bags. Beginning in 2006, McDonald's China has gradually introduced a kraft paper bag with thermal insulation properties to store take-out food in all stores, instead of using plastic food bags. This move has also received positive responses from other businesses, such as Nike, Adidas and other big consumers of plastic bags, have begun to use high-quality kraft paper bags to replace plastic shopping bags.
As kraft paper bags are oil-proof and waterproof and belong to renewable resources, it has become a popular trend in the entire packaging industry today.
