Kraft boxes

by Whitney Mendoza Whitney mendoza
The packaging is an important parameter on which not only the sales volume depends, but also the safety of the product itself (this is especially true for food products).

Kraft is translated from German as "power". This literal translation reflects the essence of the material: by Kraft paper, we mean a packaging material of increased strength. Increased resistance to various mechanical influences is the main characteristic and foremost advantage of the material.
It is impossible not to mention the environmental friendliness of Kraft paper, its simplicity and relative cheapness. These factors have ensured the competitiveness of the material. Before the appearance of Kraft boxes, the primary packaging material was polyethene, a substance that decomposes in natural conditions for a long time. Now, in some areas, packaging from Kraft boxes, made from renewable natural resources, has replaced polyethene.
The technology of material production was created more than a century ago (in 1852) in the U.S., so it would not be entirely correct to attribute Kraft paper to the latest innovations. This type of packaging is somewhat well forgotten old because the development of the middle of the XIX century found full application only at the turn of XX-XXI century.
Production
The primary raw material is wood, and the long-fibre cellulose made of it. Raw material processing involves sulphate pulping. Thanks to the extreme naturalness, recycling of used paper are possible, which prevents environmental pollution.
The shade of the material depends directly on the selected wood grade. The most common colour is brown. No bleaching technology is used to produce brown Kraft boxes. The yellow and white paper is created from pre-bleached cellulose.
The area of use of Kraft paper depends on the density of the material. The minimum mass of produced paper is 35 g/m2; the maximum thickness is 120 g/m2.
Output products are ready for use. Besides, sheet paper and Kraft paper are produced in rolls of various sizes from which it is possible to make any goods. The area of the sheets varies in a wide range: from very small to industrial.
Areas of use
*) Packaging, wrapping, manufacturing of food packaging;
*) Wrapping of fragile products and materials;
*) Production of envelopes for correspondence;
*) Manufacture of corrugated cardboard;
*) Production of garbage bags;
*) Kraft boxes with a material density of 60 g/m2 is necessary for packing bulk materials (cement, building mixtures, etc.);
*) On Kraft paper of white colour, it is convenient to put trademarks or appropriate 
*) inscriptions, illustrations;
*) Colored Kraft,which does not discolour over time, is suitable for art compositions,
*) is widely used in printing houses for book and magazine covers;
Textile industry: it uses a special kind of material - washable Kraft paper - with its appearance and properties similar to natural leather. Such Kraft is very resistant to water; it withstands the process of sewing, ironing, washing.
During repair work, Kraft paper covers the surface, which should be protected from paint drops or solvent.
Kraft boxes for business
Kraft boxes is firmly established among various packaging materials due to its impressive characteristics: it protects packaged products not only from mechanical influences but also from bright light and temperature changes.
