How to choose environmental protection, material reduction, structural optimization, and simple decoration as the main breakthroughs, using the general and green design concept to improve the design of express packaging containers, on the basis of satisfying protection, versatility and recycling. Highlighting convenience and greenness is the main idea to effectively solve the pollution of express packaging waste and practice the concept of sustainable development.
Design Principles
1. General principle
Designed according to national standards or industry standard specifications, the packaging structure is optimized or newly designed to meet the packaging and transportation of various types and sizes of goods.
2. Green principle
The greening of express packaging requires the selection of raw materials, production and processing, transportation and distribution of products, and recycling after use. The whole process is green and environmentally friendly, forming a green product packaging system.
Design ideas
After market research and data review, the following three design ideas are proposed for the problems existing in express packaging.
1. Reduce packaging materials
Material reduction generally refers to reducing the amount of host material and auxiliary materials. Through the scientific rationalization of structural design, the material of a single carton is made the most economical, and the utilization rate of the paperboard is improved. As a transport package, it reduces unnecessary design and saves printed materials.
2. Using environmentally friendly degradable materials
Tape is the most used auxiliary material in express packaging. When designing, it is considered to change the tape sealing to be sealed with degradable double-sided adhesive. It is reported that the degradation rate of the double-sided adhesive material can reach 99. %, under a certain pressure to ensure a firm bond, can withstand extreme cold and extreme heat (-40 ° C ~ 80 ° C) environment and easy to open.
3. Recycling function through mode change
At present, most of the express packaging containers are cardboard boxes or plastic bags, which have the value of recycling. E-commerce companies, carton suppliers, courier companies and consumers should join hands to reach a consensus to recycle cardboard boxes and plastic bags. For example, when the express delivery is made, a recyclable non-woven bag or a recyclable kraft paper bag can be provided, and the non-useable packaging box can be recycled in situ, which can achieve high economic and social benefits, and effectively reduce the waste of the express package. Object.
Design
Because the design object is the general express package, the packaging material is double corrugated cardboard, the thickness is 6mm, and the design reference specification is 6# express box (small and medium box).
1. Option 1
The expansion plan of the scheme is shown in Figure 1. The structural design features are sealed with degradable double-sided tape. The opening method is “one-for-one tearing”, which can improve the sealing efficiency while being firmly pasted; The handle is provided on the side for easy carrying; the bottom of the box adopts a lock-bottom structure, which is suitable for lighter and multi-category product packaging, and exhibits versatility.
2. Option 2
The structural design of the scheme is shown in Figure 4. The bottom of the box is fixed by the foot and the cover part is sealed by a plug-lock structure to ensure a high sealing and fixing strength. The box body is formed by side-locking structure, and the handle holes on both sides are convenient for lifting, which can meet the requirements of multi-category and certain weight of product storage, storage and transportation. The box is molded and sealed without the use of adhesives and tapes, which saves resources and materials, simplifies recycling and increases efficiency. The design and molding effect of the decoration implements the design principle of simplicity and reduction, and only designs and prints the necessary packaging labels.
3. Option 3
The design uses a corrugated box + non-woven bag model. The outer packaging adopts the box structure of the first scheme, and the inner packaging adopts a non-woven bag. There are three kinds of specifications for non-woven bag: 3#～5# carton bag 400mm×140mm×380mm; 6#～8# carton bag 230mm×80mm×290mm; 8# below bag 165mm×85mm×230mm.
When the consumer purchases multiple types of goods at a time, the non-woven bag is pre-placed inside the carton. After receiving the goods, the consumer can open the courier box for inspection and use the non-woven bag to hold the goods, and then fold the carton and then hand over the carton. It can be recycled by express delivery or placed in carton recycling equipment (can be set at the express delivery point) to effectively recycle or reuse the carton. Carton and non-woven bags need to be designed and used according to the type and specifications of the product. The structure is designed to meet various specifications from 3# carton (430mm × 210mm × 270mm) to 12# carton (130mm × 80mm × 90mm). In the article, the 6# carton (260mm × 150mm × 180mm) standard is taken as an example for structural display. It is worth mentioning that the non-woven bag can be used multiple times, effectively solving the problems of recycling and waste of resources in the current express package. The molding effect of the scheme is shown in Figure 7. The bag made of non-woven fabrics of different colors and printed with the brand logo helps to enhance the brand image of the product.
