Do you often use plastic bags to hold hot cooked food? Have you ever cared about ink printing on food bags? In fact, the food packages is as important as the quality of food. Packaging is the 'coat' of food. Once it has problems, food safety will also be threatened. Since 2006, McDonald's China has gradually implemented a kraft paper bag with heat preservation performance in all stores to hold take-out food instead of plastic food bags. This move has also received positive responses from other businesses, such as Nike, Adidas and other former plastic bag consumers, who have begun to replace plastic shopping bags with high-quality kraft paper bags. However, with the global prevalence of 'anti-plastic' wind, environmentalists have begun to look at ancient Kraft paper bags. Kraft paper bags are non-toxic, tasteless and pollution-free, conform to national environmental protection standards, have high strength and high environmental protection, and are currently one of the most popular environmental protection packaging materials in the world. Kraft paper bags made of kraft paper are more and more widely used. They are usually supplied with kraft paper bags in supermarkets, shopping malls, shoe shops, clothing stores and other places to facilitate customers to carry the purchased items. Kraft paper bag is an environmentally friendly packaging bag with a wide variety. The Kraft paper bag is based on the whole wood pulp paper. The color is divided into white kraft paper and yellow kraft paper. It can be coated with PP material on the paper to prevent water, the bag strength can be made into one to six layers according to the customer's requirements, and the printing and bag making are integrated. Opening and back sealing are divided into heat sealing, paper sealing and lake bottom. As we all know, paper is a recyclable resource. The raw materials for papermaking are mainly plant fibers. In addition to the three main components of cellulose, hemicellulose and lignin, there are other components with less content, such as resin and ash. In addition, there are auxiliary ingredients such as sodium sulfate. In addition to plant fibers, different fillers need to be added to different paper materials. The commonly used plastic bags are made of polyethylene and the raw material used is oil, which is already our shortage of energy. In contrast, the raw material for paper bags is trees, which is a renewable resource. The characteristics of being degradable and recyclable are naturally labeled with green labels.
