Driven by environmental awareness and cutting-edge fashion, packaging styles are undergoing quiet changes. At present, under the guidance of a group of designers and brands, kraft paper packaging is becoming a great trend in the packaging industry. In recent years, with the simplification of gift packaging, kraft paper has become the new favorite of the packaging industry due to its recyclable and multiple use and low-cost characteristics. As a packaging material, kraft paper has high strength and is usually yellowish brown. Its biggest advantage is that the production cost is low, and the film is often not required, and the cost performance is very high.
But what is the difference between kraft paper and ordinary paper? Why is it stronger than ordinary paper? In fact, kraft paper is not much different from ordinary paper in terms of manufacturing method. The main difference is that kraft paper uses relatively long wood fibers in the selection of materials, and uses caustic soda and sulfide chemicals to treat the wood. The advantage of this is that the original strength of the wood fiber can be less damaged. Therefore, the kraft paper made from this kind of pulp has tightly connected fibers, so the kraft paper bag is very strong.
In addition, compared to bleached paper, the natural brown appearance of kraft paper bags of primary color has a healthy and retro charm. And the natural brown of kraft paper makes the packaging look warm and nostalgic, with a rustic style, which is very unique when used as for packaging. This is also the reason why kraft paper packaging can become popular.
For food packaging materials, its primary function is to provide convenience and practicality. In this regard, kraft paper has an absolute advantage. It is strong enough to protect food well. And in terms of packaging liquid food, kraft paper can be kept unchanged in a humid environment, so it can prevent the outflow of liquid food and play a better role in packaging.
In addition, kraft paper bags can also meet the requirements for the materials required for the packaging of frozen foods. Compared with other foods, the temperature of frozen foods varies greatly, and strength is the main factor to be considered when packaging frozen foods. In terms of strength, it is clear that kraft paper is better than bleached kraft paper of the same quality.
At the same time, kraft paper also has a unique effect on the storage of tea. You can wrap the tea leaves in thin kraft paper, tie them tightly, and arrange them in layers around the tea pot to prevent the tea leaves from becoming damp. When storing vegetables in the refrigerator, wrap the wild vegetables with a layer of kraft paper and put them in the refrigerator, which can also prevent the growth of bacteria. In addition, because kraft paper is highly absorbent, vegetables wrapped in kraft paper can prevent the loss of moisture and nutrients.
In general, the many advantages of kraft paper bags make it more and more popular today.
