The lightweight reform of plastic flexible packaging advocates with environmental protection peers

the flexible packaging Association (FPA) said that as the second largest packaging field in the United States, flexible packaging solutions account for 3: the pendulum position is abnormal, accounting for 18% of the $145billion U.S. packaging market. Light flexible packaging includes film and laminated materials, which are conducive to the transportation of high-capacity products and reduce the raw materials required for production. For all brands, saving energy costs and reducing material costs is a revolutionary movement

production rationality of flexible packaging

in the production process, the energy used in flexible packaging 4. The prestressed concrete beam without fatigue fracture of non prestressed reinforcement at the bottom of the beam is 50% less than that of rigid bottles, and the plastic used is 60% less than that of rigid bottles

in production, flexible packaging requires less materials, produces less CO2 during transportation, and occupies less space in landfills. At the manufacturing end of the production/consumption cycle, flexible packaging is more reasonable because it has less negative impact on the environment than the corresponding hard plastic bottle. According to FPA, the packaging of flexible upright bags is 35 times higher than that of metal covered glass bottles and 21 times higher than that of aluminum cans

sustainable packaging is a major argument in the flexible packaging industry, and full environmental responsibility remains to be developed. For all consumers, recycled plastics is the answer. What's more, the case of February 8, 2017 was analyzed. The energy consumption of recycled plastics is 80% less than that of new plastic containers or bottles. But is recycling the only answer to environmental awareness? Is this applicable to flexible packaging

know yourself and know your enemy, and you will never be defeated in a hundred battles.

at the beginning of discussing these issues, we can't help but look at the imperfections of the packaging bags

although the demand for packaging bags in various fields is increasing, and the innovation of packaging bags is also improving, when it comes to the forming factors of bags, the problem of lack of adaptability innovation is still very prominent. Whether this bag is used to contain colloidal washed soap, dry granule baking seasoning, or liquid cooking sauce, its accessories are almost the same. According to the flexible packaging Association, in 2013, flexible packaging accounted for 58% of the packaging in the retail and institutional food industry, and 12% of the non food retail packaging. Flexible packaging has many advantages, such as less waste, low distribution cost and strong customizability

if we pay more attention to the rigid components contained in packaging bags, what will happen to the flexible packaging industry? What if the flexible packaging industry solves the structural problem

at present, there is no formal closed-loop system in place to deal with the recycling of flexible packaging, especially the system for multi-layer high barrier materials and aluminum foil laminated structure embedded with polyethylene (PE) layer. Single layer packaging is easier to recycle because it does not contain the center layer of aluminum foil. The recycling process of multi-layer flexible PE packaging involves the separation of each layer, which requires more steps than the traditional plastic recycling scheme. Then it is necessary to analyze, identify and recycle each layer, and further treat the plastic film to make recyclable resin. Since a large number of flexible packaging is used for food packaging, food pollution has become another obstacle to recycling. For most flexible packaging, because food pollution runs through the current recycling system, the proportion of reusable packaging is actually very small. The non regenerated polymer is sent to the anaerobic chamber for incineration to provide emission monitoring energy for the production workshop

the forward-looking thinking group (such as the flexible packaging Association) has taken a series of great measures, and it pays great attention to sustainable packaging. FPA is working with some manufacturers to study packaging for environmental safety. The sustainable plastics alliance, the association of post plastic recyclers (appr) and the flexible film recycling group (ffrg) are also vigorously promoting and carrying out public education and publicity on plastic film recycling

Barrytuner, President of the European packaging and Film Association (PAFA), once said that the British media distorted the authenticity of the value of plastic bags and "the minimum impact of plastic bags on the environment". In fact, all countries and regions are exaggerating these things about plastic bags

at present, enval's process of completely recycling aluminum parts and using pyrolysis to treat plastic parts is the best solution to deal with multi-layer packaging waste at present. However, there is no solution to fully recycle plastic parts in other plastic materials

through pyrolysis, the carbonization residue formed by plastic containing inorganic materials will contain 80% liquid carbon and 20% gaseous carbon (CO2 gas will not be produced due to the lack of oxygen in the chamber). Depending on the liquid fuel/energy requirements, this carbon can be transported to different locations. The ash produced can be used as a component of products such as concrete premixes. Carbon can be used as fuel, and companies often input mixed waste into the pyrolysis chamber to generate fuel that may not have the best availability

an effective way to turn this liquid carbon fuel into a more durable and highly integrated energy needs to be continuously studied

finding a more effective waste treatment process for flexible packaging (especially in pyrolysis) with a lower impact on the environment is a challenging task, but it is possible to achieve. As the flexible packaging industry has made various innovations, such as the use of bio based materials or the pyrolysis process of converting waste into energy, the cornerstone of further development has been laid
