It is understood, green packaging materials on the market there are many, generally can be divided into repeated reuse and regeneration of the packing material, edible packaging material, biodegradable materials and paper materials.
Repeated use of packaging materials are mainly used for glass bottle packaging beer, beverage, can be repeatedly used for many times; packing material regeneration is mainly plastic packaging, using physical methods of treatment can be made of recycled packaging containers, with chemical methods can be made into renewable packaging products. But these two methods a fly in the ointment, only to reduce the pollution to the environment, to finally face the problem of the pollution of the environment.
Biodegradable packaging materials used can be self degradation and reduction, no pollution to the environment; paper packaging recycling made of natural plant fiber utilization value is very high, the technology is also very mature.
Edible packaging material with natural edible substances (such as polysaccharides, proteins, etc.) as raw material, through different molecular interaction and the formation of edible packaging film. According to the different material and technology, can be divided into polysaccharide edible packing film, protein edible packaging film, composite edible packaging film.
Green packaging box made of France by sucrose showed that, this kind of packing has been developed, into the packaging market is, will have the use of space and more development prospect.
