Due to the continuous improvement of people’s environmental awareness, “green†and “environmental protection†have become more and more important to people. Under the advocacy of green environmental protection, designers have higher requirements for packaging materials, the intrinsic factor of green packaging. They follow the principle of "5R+1D" and make targeted choices for materials:
1. Lightweight packaging
Means to meet the various functional conditions, minimize the use of packaging materials. It is understood that the current expert in the strength test of corrugated board shows that: if the quantitative increase of corrugated paper 1g/m2, the ration of the cardboard can be reduced by 1g/m2. Therefore, in the production process of corrugated board, this method can achieve lightweight packaging.
2. Material Recycling (Return)
Refers to the recycling of used packaging products, reuse, and processing into new packaging products. At present, the issue of recycling of paper packaging materials has been basically solved, and the recycling of single plastic products (PE, P, etc.) has also made great breakthroughs, but there are still some problems in some composite plastic recycling technologies.
3. Material Reuse
It refers to the recycling of all or some of the used packaging products, and does not easily give up the packaging products that can be used again, thereby reducing the production of packaging products. Environmental packaging and distribution service is the use of the above materials to transport customers to print the printer. When the product is delivered to the customer, the package is brought back by the delivery staff for reuse. In addition, when the company recycles and reuses containers for large-sized output machines, the containers are recycled and reused according to the time required by the customer. In order to facilitate the recycling of the containers, they changed the raw materials of the boxes from the previous synthetic materials to single materials (cartons), which saved both resources and costs.
4. Material can be recycled (Recycle)
Means that used packaging products are recycled and reprocessed to be used in different fields. As composite materials have a series of difficulties in achieving recycling technology, merchants have begun to use some packaging materials made from a single material that are conducive to recycling to achieve recycling of materials. Currently, a pure polyester beverage bottle without a high-density polyethylene base has appeared on the market, and a pulp molding package can be used instead of some conventionally difficult-to-degrade plastic products.
5. Refusal to use non-ecological materials (Refuse)
It refers to the rejection of the use of packaging products that are not conducive to ecological development or can cause diseases, insect pests, etc. In terms of packaging materials, some developed countries, which are importing countries, have banned or restricted certain packaging materials (wooden boxes, straw bags, etc.) made from certain raw packaging materials and partially recycled packaging materials.
6. Degradable material
It means that in order not to form permanent waste, non-recyclable packaging waste should be decomposed and the purpose of soil improvement should be achieved through fertilization. Pulp molded products are typical multifunctional degradable products. Pulp molded lunch boxes have the advantages of heat preservation, heat insulation and pressure resistance. Pulp molded trays have excellent positioning cushioning, air permeability and fresh-keeping performance.
