Various packaging materials are often used by people in daily life. Their range is quite diverse. These are polyethylene, and air bubble wrap, and cardboard, and foam bubbles, and plastic containers, and Kraft paper, and much more.
Important criteria when choosing a material for packaging are strength, convenience, aesthetic appearance, environmental friendliness. The latter criterion is especially relevant in our time, because a huge amount of packaging materials are thrown into landfills every day, and the issue of their proper disposal is vital for environmental safety. Extremely strong Kraft wrapping paper, used for packaging purposes and the manufacture of various paper products, satisfies the above requirements to the maximum.
Benefits
Translated from German, the word "kraft" means "strength", "power". Indeed, paper of this grade is distinguished by high strength characteristics, including such indicators as resistance to fracture, punching.
Packaging of this material is well glued, does not swell when wet, is breathable and resistant to temperature changes. Kraft paper has a natural origin, which indicates its environmental friendliness.
Production technology
The technology for manufacturing high-strength wrapping paper has been known since 1852, but the production of this packaging material has gained industrial scale only a century later. From the USA, where kraft paper was first invented, the method of its production has spread all over the world. The basis for the manufacture is long-staple pulp, which is obtained from wood as a result of sulphate pulping, known as the kraft process. It is the wood base that provides high strength characteristics and resistance of paper to mechanical damage, and in addition, it makes it possible to further use this material as a secondary raw material.
Views
The color of kraft paper depends on the quality of the pulp it contains. Brown paper is obtained from unbleached wood, and bleached raw materials give a range of shades from light yellow to white. This packaging material is used for the manufacture of corrugated cardboard, convenient paper bags, bags, boxes, and envelopes. In addition, Kraft paper is produced in rolls and sheets of various sizes.
The material is small in volume and weight, easy to use. All products are characterized by high strength, which is the higher, the higherpaper weight (in the range of 35-120 g/m2). Washable kraft paper has the highest density. Its main difference is resistance to moisture. The texture of this material resembles leather, it can be ironed, washed, sewn, so washable kraft paper is often used in the textile industry.
Application
The unique properties of this material allow it to be used in many areas of human activity, primarily as unique packaging products. What is not packaged in high-strength bags and kraft paper bags! These are bulk building materials, food products, and various items that require safety during delivery. Such a strong airtight container is a reliable protection for the transportation of various goods, as well as fragile items. Bulky kraft paper envelopes for postal packaging are very popular.
Products made from this material become an excellent means of advertising if they are printed with advertising text or the manufacturer's logo. To stack the goods sold to the buyer, sellers often use boxes with bright prints and colorful bags of various configurations, with or without handles. Such attractive packaging not only reminds customers of pleasant purchases, but can also serve them for any purpose for a long time.
Colored kraft paper is also used for decorative and artistic work, such as scrapbooking or card making, and in printing for book covers.
Use of kraft paper in medicine
Kraft bags are widely used in medicine. They are used for packaging and temporary sterilization of medical instruments and kits of any kind. The packaging is hermetically sealed with an adhesive strip. When closed, the bags are impervious to microorganisms for about 50 days. The indicator on the outside of the package changes color from green to pink after sterilization, making it easy to see where the sterile medical material is located.
Kraft paper is gradually and steadily replacing synthetic packaging materials that are harmful to human he alth and dangerous to the environment, which, given the unique properties and low cost of this material, is not surprising to anyone.
