Some people who don't understand kraft paper might mistakenly believe it's made from real cowhide, or they might think it's crafted from a unique material. However, this is not the case. Allow Kunou to guide you through a deeper understanding of kraft paper!
Kraft paper, used as a packaging material, boasts high strength. It typically appears in a yellowish-brown color. Semi-bleached or fully bleached kraft pulp presents a light brown, cream, or white hue. With a basis weight ranging from 80 to 120g/m², its breaking length generally exceeds 6000m. It exhibits high tear resistance, bursting strength, and dynamic strength. Kraft paper is mostly available in roll form, though flat sheets are also available. Made from sulfate softwood pulp, it undergoes pulping and is produced on a Fourdrinier paper machine.
Nowadays, with the growing environmental awareness，more and more people are starting to use kraft paper. The introduction of the plastic limit order has further promoted the development of kraft paper, leading to widespread purchases and use. On one hand, it is environmentally friendly, and on the other, it can be used for a long time, making a certain contribution to the country's resources and environmental protection. Therefore, people advocate the use of kraft paper.
Having said all that, where can kraft paper be used?
Kraft paper is applied in various industries such as chemical and machinery, and is particularly widely used in the food packaging industry.
Kraft paper applications: Kraft paper is widely used in various packaging products, such as paper bags, handbags made of kraft paper, color boxes, gift boxes made of kraft paper, printed kraft paper, notebooks made of kraft paper, exercise books made of kraft paper, envelopes made of kraft paper, and food packaging. The principle of convenience and portability should be followed in food packaging. The tensile strength of kraft paper makes it very suitable for packaging needs. To prevent the bags from being torn when consumers carry take-out food, the packaging materials are required to have good tensile strength. Beverage packaging requires materials with a certain degree of moisture resistance and deformation resistance to prevent deformation and damage due to water absorption.
Kraft paper packaging materials are characterized by their environmental friendliness, recyclability, and cost savings. With the increasing demand for environmentally friendly packaging materials in the international market, kraft paper, known for its high strength and environmental friendliness, has emerged as a popular choice. Kunou analyzes that apart from being environmentally friendly, kraft paper packaging materials have another characteristic: they can quickly pass through customs inspection, facilitating rapid logistics and cost savings. This is because customs does not require additional testing for kraft paper and yellow kraft paper packaging materials, which is another advantage compared to wooden packaging materials. Additionally, from the perspective of usability, kraft paper packaging is conducive to mechanized production and packing and sealing processes, with high production efficiency and ease of achieving packaging standardization. Coupled with its light weight and low transportation cost, it can also be used in paper pad machines to lay plastic linings inside the boxes for cushioning, wrapping, filling, support, and moisture prevention (as shown below). From the perspective of supervision, it is acceptable. Apart from the above two points, kraft paper packaging also has the advantage of easily leaving traces of theft of goods inside the boxes, thus effectively preventing theft. When insuring against W.P.A. (With Particular Average) and TPND (Theft, Pilferage and Non-Delivery) risks during sea transportation, insurance companies accept it.
