Kraft paper is a widely used material. In addition to bags, kraft paper is also playing its role in other field. With the awareness of environmental protection being strengthened all over the world, More and more occasions tend to choose kraft paper, which promotes the application scope of kraft paper in turn. As we all know, kraft paper is made of wood pulp, which can be roughly divided into two types. One part of kraft paper is made of all wood pulp, and the other part of kraft paper is made of recycled pulp. This is one of the basic properties. Since bags made from recycled pulp do not meet food packaging requirements, manufacturers can only use wood pulp to produce food-grade kraft paper.
Moreover, this kind of kraft paper will not lose hair and powder. So some high-end packaging will also be made of this paper. And recycled pulp can be used to make envelopes, notebook covers, and shopping bags.
As the most common application of kraft paper in life, kraft paper bags can be divided into many types. According to the standard of whether there is a handle, it can be divided into those with handles and those without handles. According to the color, it can be divided into primary colors, white, black, etc., and according to whether there is printing, it can be divided into those with printed patterns and those without printed patterns. Even according to the application, it can be divided into many kinds. As for how to make kraft paper, the steps are very cumbersome. Nothing can be done overnight, and the same is true for kraft paper production. There are 11 processes before and after the production of packaging kraft paper, namely: beating, filling, sizing, whitening, purification, screening, forming, dehydration pressing, drying, calendering, and coiling to make roll paper. The production can be considered complete only after such a whole set of processes.
We have already clarified that kraft paper is a widely used material, but what exactly can it be applied to? A large part of kraft paper is made into bags. Here are many uses for kraft bags; the first is the takeaway packing bag. Compared with some brightly colored takeaway bags, bags made of kraft paper look much more low-key. But that doesn't mean they’re not competitive. On the contrary, kraft paper bags account for a much larger share of the food delivery industry than we thought. Of course, this is not only because of its low cost but also because in the fast-paced modern society, the simple design of the kraft paper bag and the warm brown color bring people a relaxed feeling, so the unmodified takeaway bag is more popular with consumers.
Many grocery bags are also made of kraft paper. It is obviously a brilliant idea to take a kraft paper bag for groceries. Because in order to organize sundries, many people will especially buy some cabinets for sundries, such as drawers, storage boxes, and so on. But these are usually very expensive, and if you want to buy a certain amount, it will bring about cost problems. But using a brown paper bag for the sundries will work fine and be cost-effective.
Food-grade kraft paper
In the classification of kraft paper, food-grade kraft paper is a very special category. There is basically nothing special about the production process of this kind of kraft paper, but it has some more requirements than ordinary kraft paper. For example, it is not allowed to use fluorescent whitening agents in the production process, and the manufacturer needs to report food grade when selling, etc.
Because kraft paper is mainly made of wood pulp, that is to say, undyed kraft paper will show a natural brown color, and there is a very important classification in food-grade kraft paper called food-grade white kraft paper. This kind of kraft paper is sought after by many people because its color looks particularly pure and clean. In order to improve the whiteness of white kraft paper, many kraft paper manufacturers will add a large amount of fluorescent powder as a whitening agent in production. However, the fluorescent powder is harmful to the human body, and long-term exposure has a risk of cancer. Therefore, using white kraft paper with fluorescent powder is prohibited in the food packaging industry.
In addition, since the kraft paper used for food is in direct contact with food. Therefore, almost all countries require companies that produce food-grade kraft paper to provide food-grade inspection reports. For example, LEGB in Germany, CE in the European Union, and FDA in the United States is the most common. These provide an important guarantee for the safety of food packaging. The requirements of different countries may differ, but the purpose is the same: to ensure food safety and sanitation.
Food-grade kraft paper is mainly made into paper cups, boxes, bowls, etc. For example, some takeaway coffee cups. Because the amount required daily is extremely large, if the coffee shop uses traditional ceramic cups, it will bring serious cost problems. But if adopt plastic cup, it is not conducive to environmental protection. Therefore, kraft paper is undoubtedly the most suitable material to make takeaway cups. Because Research shows that customers strongly prefer paper packaging over plastic and would choose an online retailer offering paper over one that doesn't, and kraft paper is 100% recyclable and can be degraded by the environment in a short time without harming the soil, plants, and animals causing adverse effects. Kraft paper cups are, without a doubt, the best to-go cups. The same goes for kraft paper boxes and paper bowls.
