With the increasing proportion of plastic packaging in the packaging industry, new types of plastic packaging materials are constantly emerging.
New-style polyester packaging dominates the plastic packaging materials. The most eye-catching target is the use of polyethylene naphthalate, which is a new-style polyester packaging material with excellent gas barrier properties, UV resistance and Heat resistance.
Because metallocene polymers have many advantages, such as good processing performance, high strength, high rigidity and good transparency, they have received great attention from the packaging industry, and many new products have been introduced. Metallocene plastics will directly attack the pp, hdpe, ldpe, and elastomer plastic markets. It is very suitable for food packaging, medical packaging, shrink film and sanitary products.
In terms of the purpose of the development of plastic packaging, the first is the reduction of plastic packaging waste, and reducing the occurrence of plastic packaging waste should be the main environmental strategy for plastic packaging. First of all, the design innovation of plastic packaging should be promoted, so that plastic packaging can achieve the lightweight or thin-walled plastic packaging under the premise of ensuring its basic performance. So far, the technological advancement of the raw material consolidation process has been able to deliver the types of plastics that reach this type of goal.
It should be understood that the recycling of plastic packaging waste materials is different in nature from the recycling of scraps during the production process. It is not only a technical problem, but also a social problem. It not only touches on economic benefits, but more importantly, social benefits and Environmental benefits. Therefore, the recycling of plastic packaging waste has a certain level of public welfare nature.
The recycling and utilization of plastic waste should not be viewed with the mentality of recycling scraps during the production process. Even in terms of technical issues, there are still decision-making elements that affirm the economic effectiveness of waste recycling and utilization techniques, and demand is particularly important.
