Full paper trend of cushioning packaging materials
2024-06-01 13:08:01
With the country's emphasis on white pollution, the use of environmentally friendly materials instead of foam plastics as a buffer packaging material has become a development trend, and all-paper packaging has become a new favorite of modern packaging to avoid trade barriers. In recent years, the development of the structure of paper packaging materials has been rapidly developed. The structure of the cushioning material has also shifted from a single type to a complex type, from a process type to a functional type. In this paper, paper honeycomb materials, corrugated paperboard and pulp molded products are taken as examples to analyze the structural development of cushioning paper materials.
Paper Honeycomb Paper Honeycomb is famous for its light weight, environmental protection, sound insulation, shock resistance and high cost performance. It is mainly used to buffer shock or vibration during product transportation or loading and unloading. The structure of the paper honeycomb mainly has a regular hexagon, a rectangle, a prism, a corrugated shape, a square, a circled circle, a close row circle, a triangle, and the like. The traditional paper honeycomb structure has a regular hexagon shape, which is interlaced by a plurality of layers of paper, dried, cut into pieces, and then pulled apart to form a regular hexagonal structure. Positive hexagonal paper honeycombs are labor intensive and are not suitable for fully automated production.
The 3D folding paper honeycomb core adopts a new packaging machinery technology, which can be produced at a high speed, and its production cost is lower than that of the conventional paper honeycomb core. The main feature of 3D folded paper honeycomb cores is that they absorb a large amount of energy compared to the current honeycomb structure for loss prevention and shock resistance. In addition, the 3D folding core can reduce its cost. Since the 3D folded paper honeycomb can be rotated, wound, and bent, it can be conveniently used for processing any packaged product, and the 3D folded paper honeycomb is relatively small, light, and has a good protection product. Irregular, fragile products can be wrapped in 3D folded paper honeycombs and placed in other packaging containers. With the new paper folding technology, it is possible to print without packaging, and this folding technology can be used to make the company's LOGO. 3D folding paper honeycomb can not only play a role in promotion, but also protect the product against shock and vibration.
In order to replace foam plastics, corrugated cardboard has been used to develop a variety of corrugated cardboard composite cushioning packaging materials. In 1996, KimDoWook and KimKiJeong developed double-ply reinforced corrugated cardboard based on the original corrugated board, which changed the interlayer in the original three-layer corrugated board into two corrugated corrugated layers, without substantially increasing the thickness of the corrugated board. The compressive strength of corrugated cardboard is increased on the basis.
It is understood that the researchers conducted a four-point bending test on five different structural forms of corrugated cardboard. The results show that the corrugated board with new structure has better structural advantages than the traditional corrugated board. The folded corrugated composite material has high bearing capacity and a large static buffering energy, and is suitable for buffer packaging of products with large weight and hard surface.
The load-bearing properties of corrugated, honeycomb, and corrugated composites are highly dependent on the mechanical properties of the honeycomb core. Corrugated, honeycomb, and corrugated composites greatly increase the thickness of the composite with a small amount of material, and the cushioning energy absorption efficiency is improved compared with the simple corrugated stacking.
Pulp molded products Pulp molded products are mainly used in industrial packaging, such as egg trays, fresh fruit trays, food and semi-finished packaging, medical device packaging, and the like. Pulp molded products are generally processed by a combination of multiple sets of molds. With the improvement of mold technology, it is now possible to produce shaped cavity pulp molded products, which are mostly used as containers or decorations. The combined processing form is a packaging function required for a certain application by a combination of a plurality of differently shaped pulp molded bodies at the time of molding. In foreign countries, disposable pulp molded urinals have replaced the multiple use urinals made of polyester materials. With the improvement of mold technology, the structure of pulp molded products tends to be more complicated and detailed.
In addition to traditional honeycomb paperboard, corrugated board and pulp model products, foam paper particles that currently meet environmental requirements are gradually being developed and used in the buffering of electronic products. A company in Hamburg, Germany, chopped waste paper and mixed it with starch. The pulverized material was granulated, placed in a sealed container, high pressure and high temperature steam were applied, and then rapidly decompressed, and the granule package foamed. The porous pellets are formed into a foam packaging material, which can be used as a buffer material, has better cushioning performance than EPS, and is suitable for buffer packaging of electronic, instrument and sensitive materials.
