Health and health food packaging green wave

The unreliability of packaging is a weakness of health foods. Many manufacturers are aware of this issue and are embarking on improvements. To this end, provide some packaging concepts of foreign developed countries, hoping to learn from them.

Environmental protection is a worldwide topic. A “green tide” is emerging in the global scope. The packaging industry must also consider environmental issues while developing. In this regard, developed countries have some new ideas:

Material Selection: Reducing Environmental Stress

When choosing packaging materials, try to use materials that are easy to handle and actively develop new packaging materials to reduce the pressure on the environment. At present, many European and American companies have developed "green packaging materials" that meet environmental requirements. Pulp forming packaging is gradually replacing traditional plastic materials that are difficult to degrade. For example, a U.S. company has developed a reusable paper packaging mat that uses old newspapers to create such packaging and can replace the widely used non-degradable foam mats.

Functional Selection: Develop Edible Packaging

Developing edible packaging is a new approach. Food packaging is a big industry for packaging industrial products, accounting for about 70% of the packaging industry. Food packaging waste also has the greatest environmental pollution. Therefore, solving the problem of food packaging waste is a major problem in the packaging industry. Developing edible packaging materials is a good way to solve the contradiction between food packaging discarding and environmental protection. Its goal is to create a food that does not affect the flavor of packaged foods. Packaging film, this film is edible.

For example, a company in Queensland, Australia, made an edible potato chip package. People can eat the potato chips and eat them without causing waste. Japan has developed decapcened chitosan made from shell materials to make edible wrapping paper. This type of edible wrapping wrapped snack noodles can be cooked directly in a hot pot. The use of edible packaging not only facilitates people's lives but also avoids packaging wastes from polluting the environment. It is worth further study.

Packaging Design: Consider Environmental Requirements

1. When designing packaging, try to use the same material or separable coexisting materials. Packaging made from a single material is easy to recycle. For example, a pure polyester coke bottle without a high-density polyethylene pedestal appears on the market, which facilitates regeneration. Multi-layered composite materials must be considered for ease of separation without hindering reuse. For example, when an organic beverage is coated on an aluminum beverage surface, the organic coating material can be burned without causing difficulty in recycling, and the composite paper-plastic packaging material is difficult to be separated and purified.

2. Design packaging that can be reused over and over again. The use of reusable packaging materials saves resources and reduces pollution, and should be strongly promoted. Japan's Asahi, Sapporo, and other beer companies have developed a longevity beer bottle that is 10% stronger than the original beer bottle, and has an average life expectancy that can be doubled and its service life can reach 16 years.

3. Simplify the packaging as much as possible to achieve proper packaging. Excessive packaging causes waste of resources and also causes unnecessary environmental pollution. Some developed countries are advocating proper packaging and have introduced some regulations in succession. For example, the U.S. has imposed a regulatory limit on the degree of complexity of product packaging in terms of a certain percentage. Excessive packaging exceeds the requirements and imposes heavy penalties. This forced the manufacturer to simplify the packaging. Japan even proposed the idea of ​​"zero packaging."

Classification and recycling: renewable resources available

As packaging waste is a large household of environmental pollution, all countries are trying their best to sort and recycle packaging waste and recycle it. For example, the classification and collection of packaging waste in Germany is very good. It not only recycles a large amount of useful materials, but also uses waste to incinerate electricity to generate energy and also reduces environmental pollution.
