In recent months, people debate about packaging and environmental protection seem intensified. As the packing effect through all aspects of daily life and even the destruction of the environment, so the packaging industry to become the focus of attention. Retailers can not wait to take action to reduce packaging on the environment has adverse effects.

To achieve real environmental protection, not just in material selection and work hard so simple. Waste and Resources Action Group (WRAP) recent research shows that British households throw away 6.7 tons per year around the food, which is equivalent to the total amount of food they buy one third of the year. As a result, is not difficult to imagine without the effective preservation of food packaging, it was discarded due to spoilage of food will be more. Although it is not this a bit of a package as a measure of an indicator of environmental performance, but it does the impact on the environment.

Retailers have also found that the storage of grapes in bulk to sell more than 5% loss rate. If the bags sold, the loss rate will drop 0.5 percentage points. If we use in packaging to protect the basket weaving, then the grapes will be reduced to 1.5% loss rate. Take the same approach was fresh cucumber wrapped in plastic film or other products will also extend the shelf life of 5 days. In these areas, often accused of "excessive" packaging, in fact, have existence value.

It is for to protect, preserve food, packaging, only these values. Therefore, any enterprises in the design and manufacture of packaging, all must pay attention to the basic functions of packaging. Although people should achieve from the various environmental protection, environmental in nature, but should not sacrifice the cost of packaging the original function. If a package can not meet the promotion, protection and preservation of the basic requirements of products, then it is there would be no meaning.

But this is not to deny any packaging on the environment can reduce the adverse impact of new materials and new technologies. Basic function of packaging and environmental performance are very important. Materials science and advanced technology to provide end users with an environmentally-friendly to meet the promotion, protection and other requirements of the packaging.

For example, extracted from corn and other cereals made from biodegradable raw material polylactic acid (PLA) resin have been described as "green" plastics. Although the RPC’s of hot forming system can produce PLA packaging materials, but they still can not meet market demand. RPC is currently only able to use this technology to produce thermoformed packaging, and can not use mold injection molding technology to produce rigid containers.
