Several types of new packaging can not be ignored

At present, the concept of environmental protection and functional consumption has spawned innovative packaging, allowing traditional packaging to have greater innovation in function, design, and environmental protection.

At present, several new types of packaging with a high degree of concern in the industry are mainly focused on material innovation and functional innovation . New packaging companies and related products have emerged on the markets of developed countries such as Europe, America and Japan, and many domestic companies have followed suit.

Material innovation refers to the adoption of new materials that make packaging more environmentally friendly and more satisfying to consumers' needs, including nano packaging, edible packaging and green packaging.

Among them, the emergence of nanotechnology has provided new ideas and technical support for packaging. New materials such as nano-barrier materials, nano-anti-static materials, nano-stealth materials, nano-antibacterial materials, and nano-coatings will gradually be developed and applied in the packaging field.

Nano-packaging materials are nano-composite packaging materials made of single-crystal or multi-crystal materials with grain sizes of 1 nm to 100 nm and other packaging materials. They can be divided into four types according to the structure: the grain size is at least in one direction. Those within the nanometer range are called three-dimensional nanomaterials; those with a layered structure are called two-dimensional nanomaterials; those with a fiber structure are called one-dimensional nanomaterials; those with an atomic cluster and atomic beam structure are called zero-dimensional nanomaterials.

The benefits of quantum size are significant, giving nanomaterials many different properties from conventional materials such as high strength, high hardness, high resistivity, low thermal conductivity, low modulus of elasticity, low density, high barrier properties, etc. Its broad application prospects in the future.

Using the characteristics of nanoparticles, one can synthesize composite materials of two or more substances with completely different atomic arrangement states from ordered and disordered phases that were difficult to achieve in the past, and provide a wider application space for flexible film packaging!

Functional innovation refers to the use of new technologies to enable packaging to achieve its original functions, including composite packaging, active packaging, and self-heating and self-cooling packaging .

At present, most nano packaging and smart packaging products in China are still in the laboratory research and development stage; while edible packaging, self-heating and self-cooling packaging have only a small scope of investment in Japan, Europe and the United States market; green packaging industry is a weak foundation, the company is small Composite packaging technology requirements are relatively low and development is relatively mature.

With the rise of the e-commerce logistics industry and people’s increasing demand for the distribution of agricultural products and processed foods, cold chain logistics has become a new industry concern. The new types of packaging currently used in this industry include composite heat-insulated cartons, composite corrugated cartons, and EPP environmental protection incubators, which can better meet the needs of future cold-chain logistics packaging both from a functional and environmental perspective. In the downstream of cold chain logistics, agricultural products will remain the main category in the future. Among them, the annual output of the fruit market is large, rapid growth, and the maturity of the cold-chain technology continues to increase, will be the star category of cold-chain logistics goods.
