As we know that Kraft paper is used in chemical industry, machinery and other industries, especially widely used in food packaging industry.

First, kraft paper is widely used in a variety of packaging supplies, paper bags, handbag kraft paper, color box, gift box kraft paper, printing kraft paper, notebook kraft paper, exercise paper, envelope special kraft paper, food packaging, a variety of high-grade commodity packaging, such as wine boxes, sports apparel gift boxes; Envelopes, such as culture, education and health, archives preservation of enterprises and institutions, such as common postal seals; It can also process shopping bags, such as shopping bags commonly used in shopping malls and brand stores, or used for box board hanging paper. The tensile advantage of kraft paper makes it very suitable for the needs of packaging, so as to avoid the disadvantage of the bag being pulled off.

Second, kraft paper can also be used as a buffer material. Some precision parts such as auto parts need to buffer, kraft paper is a good buffer material, cut it into thin strips filled in the buffer role, environmental protection, low cost.

Three, kraft paper is especially suitable for making multi-layer kraft paper bags to fill cement, putty powder, barite powder, titanium dioxide, dry powder mortar and other powdered products, but also can make insulating paper, asphalt paper, cable protection paper, plastic sealing paper, etc., with moisture proof and leak proof, convenient stacking, not easy to slip, transportation safety and other characteristics, is currently one of the most selected packaging materials at home and abroad! The benefits of packaging with kraft paper are determined by the performance of kraft paper, because kraft paper can be recycled and reused many times, renewable environmental protection, and the price is not high, printing costs are low, and cost savings.

Fourth, in order to prevent the bag from being broken when the consumer carries the takeaway food, the packaging material is required to have good tensile strength. Beverage packaging requires that the production material has a certain ability to resist moisture and not deform, to prevent water absorption deformation and damage. For the packaging of frozen food, the use of high-strength materials as packaging is also the key to consider, this material must be able to withstand the thermal expansion and contraction when freezing at low temperature and melting at high temperature, to prevent deformation, distortion, wrinkling and excessive moisture absorption can not be loaded with food. From these aspects, primary kraft paper is even more suitable than SBS paper.
