Kraft Paper Bag

Also known as natural kraft paper. It has high tensile strength, high toughness, usually brownish yellow, high tear strength, cracking and high dynamic strength. It is widely used in shopping bags, envelopes, etc. Commonly used thicknesses range from 120 grams to 300 grams of natural kraft paper. Kraft paper is generally suitable for printing monochrome or two-color and uncomplicated manuscripts. Compared to white cardboard and white paper carton coated paper, yellow kraft paper has the lowest price. Paper is a resource that can be recycled. 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 components such as sodium sulfate. In addition to plant fibers, paper also needs to add different fillers depending on the paper. The commonly used plastic bags made of polyethylene are made from petroleum, and oil is already a scarce source of energy. In contrast, paper bags are made from trees and are a renewable resource. The inherently degradable, recyclable features are naturally labeled with green labels.
