Recyclable packaging material

Abstract

The invention provides a recyclable packaging material. The recyclable packaging material comprises two or more layers of functional films with different functions and characteristics. A plurality ofbuffer supporting units with buffer and supporting functions are connected and combined together, and packages in various shapes are manufactured through the modes such as cutting, heat sealing, gluing, hot pressing, binding and folding, so that the requirement for protecting packaged objects in the transportation logistics process is met. The functional films and the buffer and supporting units are mainly made of high polymer materials which can be recycled for multiple times, and the packages made of the packaging material have better compression resistance, breakage resistance and moistureresistance and longer service life than a traditional corrugated paper package; and meanwhile, the packaging material can be recycled for multiple times, the cost can be remarkably reduced, the carbonemission and energy consumption in the production and manufacturing process can be greatly reduced, and a cheap and environment-friendly bag replacement scheme for an existing corrugated carton and various buffer filling materials is achieved.

Description

technical field [0001] The invention relates to the technical field of transport packaging, in particular to a recyclable packaging material. Background technique [0002] In the past few decades, corrugated boxes have been the most important material and packaging method in the packaging and transportation link. According to statistics, the output value of the global corrugated box industry in 2017 reached 226 billion US dollars, and the global output of corrugated boxes reached 234 billion square meters. In China, the national output of corrugated boxes climbed from 2,560.30 thousand tons in 2000 to 40,275.78 thousand tons in 2016, with a compound annual growth rate of 18.79%. With the rapid development of e-commerce and the express delivery industry in recent years, the corrugated box industry has further grown (in 2019 alone, the number of express packages in China has exceeded 60 billion, most of which will use corrugated paper packaging). Due to the inherent material...

AI Technical Summary

Problems solved by technology

Due to the inherent material and process limitations of corrugated boxes, with the sharp increase in demand, its problems have become more prominent: such as sharp fluctuations in raw material prices, pulping pollution, transportation damage, and undurable lead to a large number of discards, and with the discarded cartons, There are also a large number of non-degradable sealing tapes, express orders, various inflatable bags, foam plastic fillings, all of which are bringing more and more serious environmental pressure

Specifically, corrugated boxes and box fillings have the following disadvantages: 1. Limited performance, not moisture-proof; 2. Poor durability, cannot be reused multiple times; 3. Low recycling efficiency, recycled materials are degraded, and raw materials are difficult to recycle; 4. There are many production processes, and only large batches can be automated, which cannot meet the needs of intelligent production; 5. The larger the scale, the more stock, it is difficult to achieve low inventory and high turnover; 6. The threshold for raw material production is low, it is not easy to supervise, and it is easy to cause environmental problems Pollution; 7. The use process is accompanied by a large amount of disposable waste, etc.
