Packaging problems where strong nanomaterials have methods

With the formation of new packaging markets such as agricultural product packaging and cold chain packaging, new issues have been proposed for corrugated packaging in China, such as preservation, waterproofing, moisture resistance, anti-static, and abrasion resistance. Nowadays, with the application of nano high-tech in the field of packaging and printing, high-tech products such as nano-paper and nano-ink with special functions have been developed to solve these problems.

Nano materials are widely used in paper, and can achieve some special properties of paper. For example, the compound with the polymer matrix and the inorganic filler on the nanometer scale enables the composite material to have excellent mechanical properties, heat resistance, barrier properties, weather resistance, etc. Nano-materials can be compatible at the molecular level, and the size is smaller than the light wavelength, and the transparency is good; superconducting, photochromic, and electrochromic materials are available, which is of great significance in the manufacture of anti-counterfeiting paper and packaging paper.

The role of nano-paper in corrugated boxes is mainly to use nano-paper antibacterial preservation and hydrophobicity and other special properties to increase the anti-bacterial preservation function of corrugated boxes in packaging and improve the printing suitability of the carton.

The biggest feature of nano paper is that it has the corresponding nano function when the paper is formed. It is the most effective and lowest cost technology in corrugated box packaging technology, and its application prospect is very broad. For example, the use of super-hydrophobic nanostructures and coating technology improves the hydrophobicity and surface strength of paper. Super-hydrophobic nanostructure coating technology and its application in paper products are the first in China. In addition to the original writing, copying and other functions of this paper, this kind of nano paper also has super hydrophobic and moisture resistance that ordinary paper does not have, and has the special properties of improving the strength of the printed surface and reducing the expansion and contraction rate. Free scrolling as above. And its increased cost is only about 10% of the cost of ordinary paper. In the field of packaging materials, paper products, cartons, films, etc. have also achieved strange super-hydrophobic and super-oleophobic effects.

In addition, in the manufacture of corrugated boxes, other properties of nanomaterials can also be used to improve the performance of corrugated paper. For example, applying the characteristics of nano-hydrophobicity, the nano-water repellent is coated on the inner layer of the corrugated cardboard box, so that the surface of the cardboard box is not sticky to water, and has the functions of environmental protection, moisture resistance, moisture resistance, etc. Used for packaging beer, etc.

For fruits and some foods, product preservation is very important. However, the fresh-keeping packaging technology and process are complicated, the packaging operation, storage and transportation costs are high, and the fresh-keeping effect is not ideal. Nowadays, the nano paper with antibacterial function introduced after adopting nano high-tech has solved this problem well. Many organic antibacterial agents have the disadvantages of poor heat resistance, easy volatility, easy decomposition to produce harmful substances, and poor safety performance.

The fresh-keeping corrugated box is a special package and a technological innovation product. It is the product of the combination of modern science and technology and packaging engineering, reflecting the development direction of modern packaging technology. The key to fresh-keeping corrugated boxes is nano-modification of traditional corrugated board and fresh-keeping design and innovation of traditional corrugated box structures. The way to keep fruits and vegetables fresh is to reduce water loss, inhibit biological respiration and bacterial growth, and at the same time remove the ethylene gas that promotes their aging and maturation. Preserving corrugated cardboard is processed manually from these aspects.

Of course, the application of nanotechnology can only be glimpsed here. As nanotechnology continues to mature and improve, its application in corrugated boxes will be more extensive, and it will have a good relationship with mature technology in terms of quantity and cost. Competitive Advantage.

In short, the application of nanotechnology and nanomaterials in corrugated boxes will open up a new field of packaging technology, and their excellent characteristics and functions provide a new way for the development of the corrugated box industry.
