Green packaging needed a “coat”
China has implemented a “green food packaging generic guidelines” clearly provides that packaged food products does not allow the use of plastic foam polystyrene, polyurethane and other materials; green food packaging material used should be explicit instructions and re-use, recycling instructions and the green signs; green food packaging printing, the ink or adhesive labeling to be non-toxic, and should not be direct contact with food.
These standards will be fundamental to the food packaging, especially the green food packaging strict specifications in order to enhance their safety. The reason why I refer in particular to green packaging, because consumers pay attention to green itself, often overlooked, while creating new packaging for its pollution, so that organic foods become “contaminated food products.”
Can be found in some supermarkets, and many vegetables are green logo affixed, and carried out according to the weight of an independent packaging. However, these packages while using biodegradable plastic wrap, but the food trays are disposable plastic products; many have been cut fruit platter, also harmful to human health, using pairs of disposable foam plastic retaining net wrapped; while a considerable number of affixed high-quality rice, green label, but also the use of harmful plastic bags packed.
According to experts, is currently a lot of grain, vegetables and other food products used in plastic bags, plastic trays, the material is PVC, not only toxic to humans and cause pollution to the environment after use. In another example, some businesses had extensive use of whitening paper for food packaging. The paper in the production process, in order to improve its whiteness, most are used for very toxic to humans and animals of the fluorescent whitening agent for processing. It is particularly worth mentioning is that now there are many businesses prefer to use colored wrapping paper, resulting in pollution, more insidious. Colored wrapping paper containing benzene exceeded the color ink, if direct contact with food, you may directly endanger human health. Therefore, the green must prevent excessive benzene containing a color ink-printed “green bag.”
Industry insiders believe that without the need to change the traditional production technology at the same time, it is necessary to solve the green packaging ink and color printing process of benzene exceeded the issue, but also reduce on-site deployment of raw materials caused by waste and poisoning incidents occur, while improving the utilization of raw materials, lower production costs, reduce business risk, the best way is in accordance with GB-9685 standard, allowing only horse anhydride modified polypropylene and polyurethane adhesive is used in food trays packaging among and with benzene as solvent, a single-component pressure-sensitive adhesive must not be allowed to use. In other words, benzene printing technology should be the direction of green food packaging, packaging, food safety process from the perspective of enterprises, through technical improvements, from the source of packaging materials to achieve non-toxic harmless.
